    The paper supports the development of evidence-based emergency management frameworks of cooperation between agencies in the area of drinking water and public health, as part of developing the overall risk management culture within water utilities. We employed a qualitative research design to understand critical gaps in inter-agency relations that aggravated past drinking water and health incidents and from these identified determinants of effective relationships. We identified six critical institutional relationship components that were deficient in past incidents, namely proactivity, communication, training, sharing expertise, trust and regulation. We then analysed how these components are addressed by reputable water utilities and public health departments to develop positive examples of inter-agency cooperation. Control of different risks (e.g. public health, business, and reputation) resulting from drinking water incidents should employ a preventive framework similar to the multiple barrier approach for management of drinking water quality.

  3. Developing a state wellhead protection program: a user's guide to assist state agencies under the Safe Drinking Water Act

    1988-07-01

    The 1986 Amendments to the Safe Drinking Water Act established a new Wellhead Protection (WHP) Program to protect ground water that supplies drinking water wells from sources of contamination. Under Section 1428 of the Act, each State must prepare a WHP program and submit it to EPA by June 19, 1989. Although the law requires that every State WHP program must contain specific elements, EPA recognizes that States should be allowed flexibility to tailor program details to best suit their individual needs. The document provides an overview of the major program requirements, presents major messages that a State should consider while developing a WHP program, and presents case-study examples to illustrate how a State might address each element of its WHP program.

    Up to half the population of some states in the United States drink water from small systems not regulated by the Safe Drinking Water Act. The quality of the drinking water from these systems is generally unknown and may be suspect. In many jurisdictions, private wells are the primary source of water. In some instances, construction of wells may have met regulatory requirements but may not have adequately prevented disease transmission. Anecdotal information, periodic water-borne outbreaks, and recent well surveys suggest that there are public health concerns associated with these and similar systems. This article provides an assessment of the need for governmental oversight (regulatory and non-regulatory) of drinking water supplies, describes how a "systems-based" approach might be used to evaluate water supply systems and to identify and prevent possible contamination, and presents case studies describing the systems-based approach as well as a comprehensive approach to environmental health that includes drinking water regulation.

    Millions of people die every year around the world from diarrheal diseases much of which is caused by contaminated drinking water. By contrast, drinking water safety is largely taken for granted by many citizens of affluent nations. The ability to drink water that is delivered into households without fear of becoming ill may be one of the key defining characteristics of developed nations in relation to the majority of the world. Yet there is well-documented evidence that disease outbreaks remain a risk that could be better managed and prevented even in affluent nations. A detailed retrospective analysis of more than 70 case studies of disease outbreaks in 15 affluent nations over the past 30 years provides the basis for much of our discussion [Hrudey, S.E. and Hrudey, E.J. Safe Drinking Water--Lessons from Recent Outbreaks in Affluent Nations. London, UK: IWA Publishing; 2004.]. The insights provided can assist in developing a better understanding within the water industry of the causes of drinking water disease outbreaks, so that more effective preventive measures can be adopted by water systems that are vulnerable. This preventive feature lies at the core of risk management for the provision of safe drinking water.

  15. Safe drinking water: a public health challenge.

    PubMed

    Wigle, D T

    1998-01-01

    Disinfection of drinking water through processes including filtration and chlorination was one of the major achievements of public health, beginning in the late 1800s and the early 1900s. Chloroform and other chlorination disinfection by-products (CBPs) in drinking water were first reported in 1974. Chloroform and several other CBPs are known to cause cancer in experimental animals, and there is growing epidemiologic evidence of a causal role for CBPs in human cancer, particularly for bladder cancer. It has been estimated that 14 16% of bladder cancers in Ontario may be attributable to drinking water containing relatively high levels of CBPs; the US Environmental Protection Agency has estimated the attributable risk to be 2 17%. These estimates are based on the assumption that the associations observed between bladder cancer and CBP exposure reflect a cause-effect relation. An expert working group (see Workshop Report in this issue) concluded that it was possible (60% of the group) to probable (40% of the group) that CBPs pose a significant cancer risk, particularly of bladder cancer. The group concluded that the risk of bladder and possibly other types of cancer is a moderately important public health problem. There is an urgent need to resolve this and to consider actions based on the body of evidence which, at a minimum, suggests that lowering of CBP levels would prevent a significant fraction of bladder cancers. In fact, given the widespread and prolonged exposure to CBPs and the epidemiologic evidence of associations with several cancer sites, future research may establish CBPs as the most important environmental carcinogens in terms of the number of attributable cancers per year.

    The New South Wales (NSW) Public Health Act 2010 requires water suppliers to implement a drinking water quality assurance program that addresses the 'Framework for management of drinking water quality' in the Australian drinking water guidelines. NSW Health has recognised the importance of a staged implementation of this requirement and the need to support regional water utilities. To date, NSW Health has assisted 74 regional utilities to develop and implement their management systems. The Public Health Act 2010 has increased awareness of drinking water risk management, and offers a systematic process to identify and control risks. This has benefited large utilities, smaller suppliers, and remote and Aboriginal communities. Work is continuing to ensure implementation of the process by private suppliers and water carters.

    1989-01-01

    This book approaches the topic of safe drinking water by communicating how the EPA has responded to the mandates of Congress. Chapter 1 summarizes what is and will be involved in achieving safe drinking water. Chapter 2 describes the historical development of drinking water regulations. Chapter 3 summarizes the directives of the Safe Drinking Water Act Amendments of 1986. Chapters 4 through 9 discuss each phase of the regulatory program in turn. Specific problems associated with volatile organic chemicals, synthetic organics, inorganic chemicals, and microbiological contaminants are assessed in Chapter 4 and 5. The unique characteristics of radionuclides and their regulation are treated in Chapter 6. The disinfection process and its resultant disinfection by-products are presented in Chapter 7. The contaminant selection process and the additional contaminants to be regulated by 1989 and 1991 and in future years are discussed in Chapters 8 and 9. EPA's Office of Drinking Water's Health Advisory Program is explained in Chapter 10. The record of public water system compliance with the primary drinking water regulations is detailed in Chapter 11. Chapter 12 offers a nongovernmental perspective on the general quality of drinking water and how this is affected by a wide range of drinking water treatment technologies. Separate abstracts are processed for 5 chapters in this book for inclusion in the appropriate data bases.

    This report provides current information on the Safe Drinking Water Act and recent amendments. The report describes the evolution of the Safe Drinking Water Act and the responsibilities of base personnel involved in compliance with the Act. It also describes the monitoring requirements, analytical requirements, best available technology for controlling contaminants, and public notification requirements for regulated contaminants. The appendixes include proposed contaminants and state water quality agencies. Each Air Force public water distribution system (PWDS) must comply with the SDWA, and the National Primary Drinking Water Regulations (NPDWRs). In the United States and its territories, the provisions of the SDWA and the NPDWRs are enforced by the states except in the few instances in which the state has not been delegated primary enforcement responsibility (primacy) by the EPA. States that have primacy may establish drinking water regulations, monitoring schedules, and reporting requirements more stringent than, or in addition to, those in the NPDWRs. Air Force public water systems in these states are required to comply with these additional requirements as well as federal enforcement actions as carried out by the EPA Regional Office.

    This study aims to determine the quality of Jakarta Capital Region’s groundwater and its recommendation based on the standards set by the Indonesian government especially The Health Minister Decree No. 907 / Menkes / SK / VII / 2002 about The Drinking Water Monitoring. The study activity uses the data that carried out by Geological Agency, Ministry of Energy and Mineral Resources, Indonesia from March to April 2015. The methods used in this study are direct observation and hydrogeological measurement to measure physics and chemistry parameters. The results show that most places in the study area have the low quality of groundwater which is below the drinking water quality standards according to the government. However, at the unconfined aquifer (depth of 0-40 meters), the certain areas such as in the Kramat Jati, Halim Perdana Kusuma, Tongkol-Pademangan, and Duren sawit are still relatively safe for consumption as drinking water. In addition, the confined aquifer (depth> 40 meters) such as in the area of Cibubur, Pasar Rebo, and Jagakarsa are considered safe for consumption as drinking water. This study is expected to be used as a benchmark for researchers, especially academics in the region in order to maintain the sustainable groundwater resources in the area.

    2014-10-01

    This study examines willingness to pay (WTP) in Bangladesh for arsenic (As) safe drinking water across different As-risk zones, applying a double bound discrete choice value elicitation approach. The study aims to provide a robust estimate of the benefits of As safe drinking water supply, which is compared to the results from a similar study published almost 10 years ago using a single bound estimation procedure. Tests show that the double bound valuation design does not suffer from anchoring or incentive incompatibility effects. Health risk awareness levels are high and households are willing to pay on average about 5 percent of their disposable average annual household income for As safe drinking water. Important factors influencing WTP include the bid amount to construct communal deep tubewell for As safe water supply, the risk zone where respondents live, household income, water consumption, awareness of water source contamination, whether household members are affected by As contamination, and whether they already take mitigation measures.

  19. Pregnancy and alcohol: occasional, light drinking may be safe.

    PubMed

    2012-02-01

    Many pregnant women drink varying quantities of alcohol, although several guidelines recommend total abstinence. What is known of the dangers of alcohol for the outcome of pregnancy and for the unborn child? To answer this question, we conducted a review of the literature using the standard Prescrire methodology. Fetal alcohol syndrome, which combines facial dysmorphism, growth retardation and intellectual disability, occurs in about 5% of children who are regularly exposed to at least five standard units per day (about 50 g of alcohol per day). Four studies have explored the link between heavy maternal alcohol use over a short period and the risk of cognitive impairment in the child. The results were inconclusive, however, and the authors failed to take concomitant chronic alcohol consumption into account. A methodologically sound study showed an increase in neurological abnormalities (seizures and epilepsy) when the mother drank heavily during short periods between the 11th and 16th weeks of pregnancy. There is a risk of cognitive and behavioural problems in children whose mothers regularly drank more than 2 standard units per day. Studies involving a total of about 150 000 pregnancies sought a link between low-level alcohol consumption and abnormal pregnancy outcomes. Very few showed a statistically significant link, and the results are undermined by the failure to take other risk factors into account. Weekly consumption of 5 standard units or more during pregnancy has been linked to an increased risk of cryptorchidism. Studies in a total of 57 000 pregnancies showed no effect of minimal alcohol consumption on the risk of malformations. A study of 1000 pregnancies showed a statistically significant risk of major malformations, but there were several apparent biases. A link between infant mortality and alcohol consumption during pregnancy was examined in large cohort studies. Consumption of at least 4 standard units per week increased the risk of early neonatal

    2016-06-01

    The Safe Drinking Water Act 2011 was introduced in South Australia to provide clear direction to drinking water providers on how to achieve water safety. The Act requires drinking water providers to register with SA Health and develop a risk management plan (RMP) for their water supply that includes operational and verification monitoring plans and an incident notification and communication protocol. During the first year of operation, 212 drinking water providers registered under the Act, including one major water utility and a range of small to medium sized providers in regional and remote areas of the State. Information was captured on water source(s) used and water treatment. Rainwater was the most frequently reported drinking water source (66%), followed by bore water (13%), on-supply or carting of mains water (13%), mixed source (rainwater with bore water backup) (6%) and surface water (3%). The majority of providers (91%) treated the water supply, 87% used disinfection. During the first year of operation, 16 water quality incidents were formally reported to SA Health. These included both microbial and chemical incidents.

    Arsenic contamination of drinking water is a serious public health threat. In Bangladesh, eight major safe water options provide an alternative to contaminated shallow tubewells: piped water supply, deep tubewells, pond sand filters, community arsenic-removal, household arsenic removal, dug wells, well-sharing, and rainwater harvesting. However, it is uncertain how well these options are accepted and used by the at-risk population. Based on the RANAS model (risk, attitudes, norms, ability, and self-regulation) this study aimed to identify the acceptance and use of available safe water options. Cross-sectional face-to-face interviews were used to survey 1,268 households in Bangladesh in November 2009 (n = 872), and December 2010 (n = 396). The questionnaire assessed water consumption, acceptance factors from the RANAS model, and socioeconomic factors. Although all respondents had access to at least one arsenic-safe drinking water option, only 62.1% of participants were currently using these alternatives. The most regularly used options were household arsenic removal filters (92.9%) and piped water supply (85.6%). However, the former result may be positively biased due to high refusal rates of household filter owners. The least used option was household rainwater harvesting (36.6%). Those who reported not using an arsenic-safe source differed in terms of numerous acceptance factors from those who reported using arsenic-safe sources: non-users were characterized by greater vulnerability; showed less preference for the taste and temperature of alternative sources; found collecting safe water quite time-consuming; had lower levels of social norms, self-efficacy, and coping planning; and demonstrated lower levels of commitment to collecting safe water. Acceptance was particularly high for piped water supplies and deep tubewells, whereas dug wells and well-sharing were the least accepted sources. Intervention strategies were derived from the results in order to

    Despite substantial advances in the past 100 years in public health, technology and medicine, 20% of the world population, mostly comprised of the poor population segments in developing countries (DCs), still does not have access to safe drinking water. To reach the United Nations (UN) Millennium Goal of halving the number of people without access to safe water by 2015, the global community will need to provide an additional one billion urban residents and 600 million rural residents with safe water within the next twelve years. This paper examines current water treatment measures and implementation methods for delivery of safe drinking water, and offers suggestions for making progress towards the goal of providing a timely and equitable solution for safe water provision. For water treatment, based on the serious limitations of boiling water and chlorination, we suggest an approach based on filtration coupled with ultraviolet (UV) disinfection, combined with public education. Additionally, owing to the capacity limitations for non-governmental organizations (NGOs) to take on this task primarily on their own, we suggest a strategy based on financially sustainable models that include the private sector as well as NGOs.

    Results of recent epidemiologic studies suggest the need to reassess the safe upper limit in drinking water of selenium, a metalloid with both toxicological and nutritional properties. Observational and experimental human studies on health effects of organic selenium compounds consumed through diet or supplements, and of inorganic selenium consumed through drinking water, have shown that human toxicity may occur at much lower levels than previously surmised. Evidence indicates that the chemical form of selenium strongly influences its toxicity, and that its biological activity may differ in different species, emphasizing the importance of the few human studies on health effects of the specific selenium compounds found in drinking water. Epidemiologic studies that investigated the effects of selenate, an inorganic selenium species commonly found in drinking water, together with evidence of toxicity of inorganic selenium at low levels in from in vitro and animal studies, indicate that health risks may occur at exposures below the current European Union and World Health Organization upper limit and guideline of 10 and 40 μg/l, respectively, and suggest reduction to 1 μg/l in order to adequately protect human health. Although few drinking waters are currently known to have selenium concentrations exceeding this level, the public health importance of this issue should not be overlooked, and further epidemiologic research is critically needed in this area.

  11. Developing a national framework for safe drinking water--case study from Iceland.

    2015-03-01

    Safe drinking water is one of the fundaments of society and experience has shown that a holistic national framework is needed for its effective provision. A national framework should include legal requirements on water protection, surveillance on drinking water quality and performance of the water supply system, and systematic preventive management. Iceland has implemented these requirements into legislation. This case study analyzes the success and challenges encountered in implementing the legislation and provide recommendations on the main shortcomings identified through the Icelandic experience. The results of the analysis show that the national framework for safe drinking water is mostly in place in Iceland. The shortcomings include the need for both improved guidance and control by the central government; and for improved surveillance of the water supply system and implementation of the water safety plan by the Local Competent Authorities. Communication to the public and between stakeholders is also insufficient. There is also a deficiency in the national framework regarding small water supply systems that needs to be addressed. Other elements are largely in place or on track. Most of the lessons learned are transferable to other European countries where the legal system around water safety is built on a common foundation from EU directives. The lessons can also provide valuable insights into how to develop a national framework elsewhere.

  12. Public health and regulatory considerations of the Safe Drinking Water Act.

    PubMed

    Raucher, R S

    1996-01-01

    This paper provides an overview of the public health and economic issues associated with drinking water quality regulations in the United States. A historic perspective is provided by the use of filtration and chlorine disinfection, and of public health laws from the early 20th century up to passage of the Safe Drinking Water Act (SDWA), in 1974. The contaminants regulated under the Act, and the 1986 Amendments to the SDWA, are evaluated according to health endpoint, related issues in risk assessment, and the cost of complying with associated regulations. Risk-cost and benefit-cost analyses are offered for carcinogens, systemics, and pathogens. The paper describes the evolution of public health issues from the initial focus on waterborne infectious diseases to concerns over chemical contaminants, and the recent reemergence of microbials as the high-priority public health concern.

    Since the discovery of Arsenic (As) in Bangladesh groundwater in 1993, there has been a limited success in mitigation and several millions of people are at health risk. Tubewell has been recognized as widely accepted option due to its easy operation, almost no cost for maintenance and the availability of year round water. Since a significant proportion of shallow wells (usually < 80m) are at risk with As-contamination, deep wells are drilled to depths of around 250 m as a mitigation option. Compared to safe water demand, the number of deep wells is still very low, as the installation cost is beyond affordability of the local community. Hydrogeochemical characterization of shallow, intermediate deep and deep aquifer systems were performed through monitoring of groundwater using depth-specific piezometers (n=82) installed in 15 locations in Matlab area of Bangladesh. Monitoring was done over a 3 year period (pre- and post-monsoon for 2009-2011 period). Results from additional 87 existing drinking water supply tubewells were also considered for the study. For the installation of shallow drinking water wells, one aim of this study was to develop a sediment color tool on the basis of local driller's color perception of sediments (Black, White, Off-white and Red), As concentration of tubewell waters and respective color of aquifer sediments. Average and median values of As, less than the WHO guideline value of 10 μg/L observed from 39 wells installed in red sands gave strong evidence that red sediments provide As-safe water. Arsenic concentrations in more than 90% of the 66 shallow wells installed in black sands were high with an average value of 239 μg/L. Therefore, it is recommended to avoid installation of shallow wells in aquifers consisting of black sands. The use of Munsell Color Chart for the characterization of 2240 sediment samples collected from each of 1.5 m section up to a depth of 100 m from 15 locations spread over 410 km2 area led to identify 60 color

    To supply the population with qualitative potable water is a priority problem in the provision of sanitary-and-epidemiologic well-being and in the prevention of disease in the Vologda Region. The monitoring of the results of laboratory control over the quality of drinking-water and the assessment of health risk enabled a package of measures to be proposed to optimize the conditions of drinking water supply in the Vologda Region. The risk assessment technology used by a state agency for sanitary-and-epidemiological surveillance makes it possible to substantiate a system of actions to organize household water use and to include scientifically grounded proposals into the developed regional and local programs.

    Almost half of all deaths from drinking microbiologically unsafe water occur in Sub-Saharan Africa. Household water treatment and safe storage (HWTS) systems, when consistently used, can provide safer drinking water and improve health. Social marketing to increase adoption and use of HWTS depends both on the prices of and preferences for these systems. This study included 556 households from rural Tanzania across two low-income districts with low-quality water sources. Over 9 months in 2012 and 2013, we experimentally evaluated consumer preferences for six "low-cost" HWTS options, including boiling, through an ordinal ranking protocol. We estimated consumers' willingness to pay (WTP) for these options, using a modified auction. We allowed respondents to pay for the durable HWTS systems with cash, chickens or mobile money; a significant minority chose chickens as payment. Overall, our participants favored boiling, the ceramic pot filter and, where water was turbid, PuR™ (a combined flocculant-disinfectant). The revealed WTP for all products was far below retail prices, indicating that significant scale-up may need significant subsidies. Our work will inform programs and policies aimed at scaling up HWTS to improve the health of resource-constrained communities that must rely on poor-quality, and sometimes turbid, drinking water sources.

    2011-01-01

    Source water protection has gained considerable attention in the water resources literature particularly after several well publicized (non-First Nations) water contamination events in Canada. This short report explores health and place through an examination of access to safe drinking water in a developed country. For First Nations in Canada, safe drinking water remains a serious, albeit under-reported, problem. The incidence of contaminated drinking water is pervasive in many First Nations communities. Attempts to "fix" water quality problems using technology alone have produced only limited success. It will be shown that greater attention to source water protection has potential for both to improve drinking water quality as well as to re-connect health and place for First Nations in Canada.

    2000-01-01

    At the fundamental level, there are remarkable parallels between developed and less developed countries in problems of providing safe drinking water in rural areas, but of course, they differ greatly in degree and in the opportunities for resolution. Small water supplies frequently encounter difficulty accessing sufficient quantities of drinking water for all domestic uses. If the water must be treated for safety reasons, then treatment facilities and trained operating personnel and finances are always in short supply. Ideally, each solution should be sustainable within its own cultural, political and economic context, and preferably with local personnel and financial resources. Otherwise, the water supply will be continuously dependent on outside resources and thus will not be able to control its destiny, and its future will be questionable. The history of success in this regard has been inconsistent, particularly in less developed but also in some developed countries. The traditional and ideal solution in developing countries has been central water treatment and a piped distribution network, however, results have had a mixed history primarily due to high initial costs and operation and maintenance, inadequate access to training, management and finance sufficient to support a fairly complex system for the long term. These complete systems are also slow to be implemented so waterborne disease continues in the interim. Thus, non-traditional, creative, cost-effective practical solutions that can be more rapidly implemented are needed. Some of these options could involve: small package central treatment coupled with non piped distribution, e.g. community supplied bottled water; decentralized treatment for the home using basic filtration and/or disinfection; higher levels of technology to deal with chemical contaminants e.g. natural fluoride or arsenic. These technological options coupled with training, technical support and other essential elements like community

    QC sample results are required in order to have confidence in the results from analytical tests. Some of the AOAC water methods include specific QC procedures, frequencies, and acceptance criteria. These are considered to be the minimum controls needed to perform the method successfully. Some regulatory programs, such as those in 40 CFR Part 136.7, require additional QC or have alternative acceptance limits. Essential QC measures include method calibration, reagent standardization, assessment of each analyst's capabilities, analysis of blind check samples, determination of the method's sensitivity (method detection level or quantification limit), and daily evaluation of bias, precision, and the presence of laboratory contamination or other analytical interference. The details of these procedures, their performance frequency, and expected ranges of results are set out in this manuscript. The specific regulatory requirements of 40 CFR Part 136.7 for the Clean Water Act, the laboratory certification requirements of 40 CFR Part 141 for the Safe Drinking Water Act, and the ISO 17025 accreditation requirements under The NELAC Institute are listed.

    Human beings are frequently exposed to pathogens and heavy metals through ingestion of contaminated drinking water throughout the world particularly in developing countries. The present study aimed to assess the quality of water used for drinking purposes in Malakand Agency, Pakistan. Water samples were collected from different sources (dug wells, bore wells, tube wells, springs, and hand pumps) and analyzed for different physico-chemical parameters and bacterial pathogens (fecal coliform bacteria) using standard methods, while heavy metals were analyzed using atomic absorption spectrophotometry (AAS-PEA-700). In the study area, 70 % of water sources were contaminated with F. coliform representing high bacterial contamination. The heavy metals, such as Cd (29 and 8 %), Ni (16 and 78 %), and Cr (7 %), exceeded their respective safe limits of WHO (2006) and Pak-EPA (2008), respectively, in water sources, while Pb (9 %) only exceeded from WHO safe limit. The risk assessment tools such as daily intake of metals (DIMs) and health risk indexes (HRIs) were used for health risk estimation and were observed in the order of Ni > Cr > Mn > Pb > Cd and Cd > Ni > Pb > Mn > Cr, respectively. The HRI values of heavy metals for both children and adults were <1, showing lack of potential health risk to the local inhabitants of the study area.

    An estimated 1.6 million people die from diarrheal diseases each year due to lack of access to safe water and sanitation, and persons with physical disabilities face additional barriers. In Cambodia, approximately 5% of the population is disabled, presenting substantial obstacles in accessing these basic services. The purpose of this study was twofold: first, to identify the challenges facing persons with physical disabilities in accessing safe household water and basic hygiene in rural Cambodia; and, second, to use these results to generate policy and practice recommendations for the water and sanitation hygiene sector implementing water treatment system interventions in rural settings. Fifteen field interviews were conducted with persons with physical disabilities. Thematic analysis was used to identify six main themes. The results indicated that environmental barriers to access were greater in the workplace than household settings and those persons with disabilities had greater awareness about safe drinking water compared to basic hygiene. Additionally, lack of physical strength, distance to water, and lack of financial means were noted as common access barriers. The findings support ongoing research and offer insight into the particular challenges facing persons with physical disabilities in rural areas in accessing safe drinking water and basic hygiene.

Using a sample of 304 blue-collar retirees, our findings indicate that, when controlling for pre-retirement drinking behavior, perceptions of retirement as the result of a more forced or involuntary decision are associated with greater alcohol consumption, while perceptions of retirement as the result of a more volitional or voluntary process are associated with lower levels of alcohol consumption and a lower risk of problematic drinking behavior. Our results also indicate that pre-retirement job satisfaction amplifies the former relationship, while attenuating the latter one. PMID:19956364

    Protecting the public from waterborne diseases is an environmental health responsibility that every government worldwide must deal with. Canada's recent experience with waterborne outbreaks has brought the effectiveness of its water-monitoring and treatment systems under scrutiny. This paper focuses on microbial waterborne diseases and the shortcomings of drinking-water systems, dividing them into source control, monitoring, treatment, and operation, epidemiologic, and risk communication issues. Whereas some of these issues are often addressed, others, such as risk communication issues, are less frequently included in drinking water-management plans. Lessons can be learned from the Canadian experience, as these issues are applicable worldwide and especially in the developed world.

    Adequate and safe water is important for human health and well-being, economic production, and sustainable development. Failure to ensure the safety of drinking water may expose the community to the risk of outbreaks of waterborne and infectious diseases. Although drinking water is a basic human right, many people do not have access to safe and adequate drinking water or proper sanitation facilities. The authors conducted a study to assess the quantity, cost, continuity, coverage, and quality of drinking water in the village of Zawtar El-Charkieh, Lebanon. Their aim was to identify the challenges of sustainable access to safe drinking water in order to determine the short-term management actions and long-term strategies to improve water quality. Results revealed that contamination of the source, absence of any disinfection method or insufficient dose, poor maintenance operations, and aging of the networks are significant factors contributing to water contamination during the storage and distribution process. Establishing a comprehensive drinking water system that integrates water supply, quality, and management as well as associated educational programs in order to ensure the safety and sustainability of drinking water supplies is essential.

    To ascertain the quality of drinking water being supplied, water quality monitoring and surveillance was conducted in Gangtok city at various treatment stages, service reservoirs, distribution network, public standposts, and households. No significant change in raw water quality was observed on day-to-day basis. Residual chlorine was found in the range of nil to 0.2 mg/l in the sump water/finished water. Throughout the year (i.e., during summer, winter, and monsoon seasons), the total coliform and fecal coliform counts were ranged from nil to 7 CFU/100 ml and nil to 3 CFU/100 ml, respectively, in sump water of Selep and VIP complex water treatment plant; however, at consumer end, those were observed as nil to 210 CFU/100 ml and nil to 90 CFU/100 ml, respectively. These variations in bacterial counts among the different service reservoirs and consumer ends may be attributed to the general management practices for maintenance of service reservoirs and the possibility of enroute contamination. Evaluation of the raw water quality indicates that the water is suitable for drinking after conventional treatment followed by disinfection. The finished water quality meets the level of standards described as per Bureau of Indian Standard specifications (BIS:10500 1991) for potability in terms of its physicochemical characteristics.

    In rural Bangladesh, drinking water supply mostly comes from shallow hand tubewells installed manually by the local drillers, the main driving force in tubewell installation. This study was aimed at developing a sediment color tool on the basis of local driller's perception of sediment color, arsenic (As) concentration of tubewell waters and respective color of aquifer sediments. Laboratory analysis of 521 groundwater samples collected from 144 wells during 2009 to 2011 indicate that As concentrations in groundwater were generally higher in the black colored sediments with an average of 239 μg/L. All 39 wells producing water from red sediments provide safe water following the Bangladesh drinking water standard for As (50 μg/L) where mean and median values were less than the WHO guideline value of 10 μg/L. Observations for off-white sediments were also quite similar. White sediments were rare and seemed to be less important for well installations at shallow depths. A total of 2240 sediment samples were collected at intervals of 1.5m down to depths of 100 m at 15 locations spread over a 410 km(2) area in Matlab, Bangladesh and compared with the Munsell Color Chart with the purpose of direct comparison of sediment color in a consistent manner. All samples were assigned with Munsell Color and Munsell Code, which eventually led to identify 60 color shade varieties which were narrowed to four colors (black, white, off-white and red) as perceived and used by the local drillers. During the process of color grouping, participatory approach was considered taking the opinions of local drillers, technicians, and geologists into account. This simplified sediment color tool can be used conveniently during shallow tubewell installation and thus shows the potential for educating local drillers to target safe aquifers on the basis of the color characteristics of the sediments.

  11. The quest for safe drinking water: an example from Guinea-Bissau (West Africa).

    While humans require water for life, one-sixth of our species lives without access to safe water. In Africa, the situation is particularly acute because of global warming, the progression of the Sahara desert, civil unrest and poor governance, population growth, migration and poverty. In rural areas, the lack of adequate safe water and sanitary infrastructures leaves millions with doubtful water quality, increasing the harshness of daily life. In this paper, a pilot study was conducted during the wet season on Bolama Island (Guinea-Bissau, West Africa), a UNESCO Man and the Biosphere Reserve. Twenty-eight shallow wells, supplying water to most of the population, were sampled for microbiological, physical and chemical water quality characteristics. A ten-parameter water quality index (WQI) adapted to tropical conditions was applied to compare the different wells. About 79% of the wells showed moderate to heavy fecal contamination. From the surveyed parameters, it was found that chemical contamination was less important, although all samples were acidic, with the pH averaging 5.12+/-0.08. The WQI was 43+/-4% (0%-worst; 100%-best quality), showing that the water from the majority of wells was polluted but should be suitable for domestic use after appropriate treatment. At the onset of the wet season, diarrhea represented 11.5% of all medical cases, 92.5% of which were children aged <15. This paper suggests inexpensive steps to reduce the fecal contamination and control the pH in order to increase the potability of the well water and, concomitantly, to raise the living standards of the population in one of the poorest countries of the world.

    Intervention trials are used extensively to assess household water treatment (HWT) device efficacy against diarrheal disease in developing countries. Using these data for policy, however, requires addressing issues of generalizability (relevance of one trial in other contexts) and systematic bias associated with design and conduct of a study. To illustrate how quantitative microbial risk assessment (QMRA) can address water safety and health issues, we analyzed a published randomized controlled trial (RCT) of the LifeStraw Family Filter in the Congo. The model accounted for bias due to (1) incomplete compliance with filtration, (2) unexpected antimicrobial activity by the placebo device, and (3) incomplete recall of diarrheal disease. Effectiveness was measured using the longitudinal prevalence ratio (LPR) of reported diarrhea. The Congo RCT observed an LPR of 0.84 (95% CI: 0.61, 1.14). Our model predicted LPRs, assuming a perfect placebo, ranging from 0.50 (2.5-97.5 percentile: 0.33, 0.77) to 0.86 (2.5-97.5 percentile: 0.68, 1.09) for high (but not perfect) and low (but not zero) compliance, respectively. The calibration step provided estimates of the concentrations of three pathogen types (modeled as diarrheagenic E. coli, Giardia, and rotavirus) in drinking water, consistent with the longitudinal prevalence of reported diarrhea measured in the trial, and constrained by epidemiological data from the trial. Use of a QMRA model demonstrated the importance of compliance in HWT efficacy, the need for pathogen data from source waters, the effect of quantifying biases associated with epidemiological data, and the usefulness of generalizing the effectiveness of HWT trials to other contexts.

    Quality assurance (QA) and quality control (QC) data are required in order to have confidence in the results from analytical tests and the equipment used to produce those results. Some AOAC water methods include specific QA/QC procedures, frequencies, and acceptance criteria, but these are considered to be the minimum controls needed to perform a microbiological method successfully. Some regulatory programs, such as those at Code of Federal Regulations (CFR), Title 40, Part 136.7 for chemistry methods, require additional QA/QC measures beyond those listed in the method, which can also apply to microbiological methods. Essential QA/QC measures include sterility checks, reagent specificity and sensitivity checks, assessment of each analyst's capabilities, analysis of blind check samples, and evaluation of the presence of laboratory contamination and instrument calibration and checks. The details of these procedures, their performance frequency, and expected results are set out in this report as they apply to microbiological methods. The specific regulatory requirements of CFR Title 40 Part 136.7 for the Clean Water Act, the laboratory certification requirements of CFR Title 40 Part 141 for the Safe Drinking Water Act, and the International Organization for Standardization 17025 accreditation requirements under The NELAC Institute are also discussed.

    Treatment of mice with 15 mg l(-1) sodium fluoride (NaF) for 30 days increased the number of cell death, chromosomal aberrations (CAs) and 'cells with chromatid breaks' (aberrant cells) compared with control. The present study was intended to determine whether the fluoride (F)-induced genotoxicity could be reduced by substituting high F-containing water after 30 days with safe drinking water, containing 0.1 mg F ions l(-1). A significant fall in percentage of CAs and aberrant cells after withdrawal of F-treatment following 30 days of safe water treatment in mice was observed which was highest after 90 days, although their levels still remained significantly high compared with the control group. This observation suggests that F-induced genotoxicity could be reduced by substituting high F-containing water with safe drinking water. Further study is warranted with different doses and extended treatment of safe water to determine whether the induced damages could be completely reduced or not.

    To delineate arsenic (As) safe aquifer(s) within shallow depth, the present study has investigated the shallow hydrostratigraphic framework over an area of 100 km(2) at Chakdaha Block of Nadia District, West Bengal. Drilling of 29 boreholes and subsequent hydrostratigraphic modeling has identified three types of aquifer within 50 m below ground level (bgl). Aquifer-1 represents a thick paleochannel sequence, deposited parallel to the River Hooghly and Ichamati. Aquifer-2 is formed locally within the overbank deposits in the central floodplain area and its vertical extension is strictly limited to 25 m bgl. Aquifer-3 is distributed underneath the overbank deposits and represents an interfluvial aquifer of the area. Aquifer-3 is of Pleistocene age (~70 ka), while aquifer-1 and 2 represent the Holocene deposits (age <9.51 ka), indicating that there was a major hiatus in the sediment deposition after depositing the aquifer-3. Over the area, aquifer-3 is markedly separated from the overlying Holocene deposits by successive upward sequences of brown and olive to pale blue impervious clay layers. The groundwater quality is very much similar in aquifer-1 and 2, where the concentration of As and Fe very commonly exceeds 10 μg/L and 5 mg/L, respectively. Based on similar sediment color, these two aquifers have jointly been designated as the gray sand aquifer (GSA), which constitutes 40% (1.84×10(9) m(3)) of the total drilled volume (4.65×10(9) m(3)). In aquifer-3, the concentration of As and Fe is very low, mostly <2 μg/L and 1mg/L, respectively. This aquifer has been designated as the brown sand aquifer (BSA) according to color of the aquifer materials and represents 10% (4.8×10(8) m(3)) of the total drilled volume. This study further documents that though the concentration of As is very low at BSA, the concentration of Mn often exceeds the drinking water guidelines.

    PubMed

    2008-08-01

    The goals of environmental legislation and associated regulations are to protect public health, natural resources, and ecosystems. In this context, monitoring programs should provide timely and relevant information so that the regulatory community can implement legislation in a cost-effective and efficient manner. The Safe Drinking Water Act (SDWA) of 1974 attempts to ensure that public water systems (PWSs) supply safe water to its consumers. As is the case with many other federal environmental statutes, SDWA monitoring has been implemented in relatively uniform fashion across the USA. In this three part series, spatial and temporal patterns in water quality data are utilized to develop, compare, and evaluate the economic performance of alternative place-based monitoring approaches to current monitoring practice. Under the Safe Drinking Water Act (SDWA), a common list of over 90 contaminants is analyzed nationwide using EPA-authorized laboratory procedures. National and state-level summaries of SDWA data have shown that not all contaminants occur in all places at all times. This hypothesis is confirmed and extended by showing that only a few (less than seven) contaminants are of concern in any one of 19 Iowa surface water systems studied. These systems collectively serve about 350,000 people and their sizes vary between 1,200 and 120,000. The distributions of contaminants found in these systems are positively skewed, with many non-detect measurements. A screening strategy to identify such contaminants in individual systems is presented. These findings have significant implications not only for the design of alternative monitoring programs, but also in multi-billion-dollar decisions that influence the course of future drinking water infrastructure, repair, and maintenance investments.

    This research is a continuation of an earlier work, which evaluated the United States Environmental Protection Agency's Perchlorate Method 332.0, in which standards were prepared in deionized water over an extended concentration range (i.e., to a maximum of 200 μg/L). This current paper investigates the performance of the same method in which standards were made in simulated drinking water. A microbore format with a 15-μL injection volume was employed to conduct a recovery study and generate recovery curves (which hold the key to a statistically sound assessment of method performance in more complex matrices). The maximum analyte concentration range was 1 to 200 μg/L. For various subset concentration ranges, recovery evaluations were made using both raw peak-area data and analyte responses scaled by the internal standard (ISTD). The results indicate that in complicated matrices such as drinking water, ISTDs may not provide simultaneously high precision and recovery.

    In collaboration with a local non-profit organization, this study evaluated the expansion of a program that promoted and installed Mesita Azul, an ultraviolet-disinfection system designed to treat household drinking water in rural Mexico. We conducted a 15-month, cluster-randomized stepped wedge trial by randomizing the order in which 24 communities (444 households) received the intervention. We measured primary outcomes (water contamination and diarrhea) during seven household visits. The intervention increased the percentage of households with access to treated and safely stored drinking water (23–62%), and reduced the percentage of households with Escherichia coli contaminated drinking water (risk difference (RD): −19% [95% CI: −27%, −14%]). No significant reduction in diarrhea was observed (RD: −0.1% [95% CI: −1.1%, 0.9%]). We conclude that household water quality improvements measured in this study justify future promotion of the Mesita Azul, and that future studies to measure its health impact would be valuable if conducted in populations with higher diarrhea prevalence.

    2008-06-15

    The lack of safe water creates a tremendous burden of diarrheal disease and other debilitating, life-threatening illnesses for people in the developing world. Point-of-use (POU) water treatment technology has emerged as an approach that empowers people and communities without access to safe water to improve water quality by treating it in the home. Several POU technologies are available, but, except for boiling, none have achieved sustained, large-scale use. Sustained use is essential if household water treatment technology (HWT) is to provide continued protection, but it is difficult to achieve. The most effective, widely promoted and used POU HWTs are critically examined according to specified criteria for performance and sustainability. Ceramic and biosand household water filters are identified as most effective according to the evaluation criteria applied and as having the greatest potential to become widely used and sustainable for improving household water quality to reduce waterborne disease and death.

    The objectives of this cross-sectional study were to detect the presence of Cryptosporidium spp. and Giardia duodenalis in drinking water treatments plants (DWTPs) in Galicia (NW Spain) and to identify which species and genotype of these pathogenic protozoans are present in the water. Samples of untreated water (surface or ground water sources) and of treated drinking water (in total, 254 samples) were collected from 127 DWTPs and analysed by an immunofluorescence antibody test (IFAT) and by PCR. Considering the untreated water samples, Cryptosporidium spp. were detected in 69 samples (54.3%) by IFAT, and DNA of this parasite was detected in 57 samples (44.8%) by PCR, whereas G. duodenalis was detected in 76 samples (59.8%) by IFAT and in 56 samples (44.0%) by PCR. Considering the treated drinking water samples, Cryptosporidium spp. was detected in 52 samples (40.9%) by IFAT, and the parasite DNA was detected in 51 samples (40.1%) by PCR, whereas G. duodenalis was detected in 58 samples (45.6%) by IFAT and in 43 samples (33.8%) by PCR. The percentage viability of the (oo)cysts ranged between 90.0% and 95.0% in all samples analysed. Cryptosporidium andersoni, C. hominis, C. parvum and assemblages A-I, A-II, E of G. duodenalis were identified. The results indicate that Cryptosporidium spp. and G. duodenalis are widespread in the environment and that DWTPs are largely ineffective in reducing/inactivating these pathogens in drinking water destined for human and animal consumption in Galicia. In conclusion, the findings suggest the need for better monitoring of water quality and identification of sources of contamination.

    Naturally occurring arsenic (As) in Holocene aquifers in Bengal basin (India and Bangladesh) have undermined a long success of supplying the population with safe drinking water. Several studies have shown that many of the tested mitigation options have not been well accepted by the people. Instead, local drillers target presumed safe groundwater on the basis of the colour of the sediments. The overall objective of the study has thus been focused on assessing the potential for local drillers to target As safe groundwater. The specific objectives have been to validate the correlation between aquifer sediment colours and groundwater chemical composition, characterize aqueous and solid phase geochemistry and dynamics of As mobility and to assess the risk for cross-contamination of As between aquifers in areas of southeastern Bangladesh and West Bengal. Drillings to a depth of 60 m revealed two distinct hydrostratigraphic units, a strongly reducing aquifer unit with black to grey sediments overlying a patchy sequence of weathered and oxidised white, yellowish-grey to reddish-brown sediment. The aquifers are separated by an impervious clay unit. The reducing aquifer is characterized by high concentrations of dissolved As, DOC, Fe and PO43--tot. On the other hand, the off-white and red sediments contain relatively higher concentrations of Mn and SO42- and low As. Groundwater chemistry correlates well with the colours of the aquifer sediments. Geochemical investigations indicate that secondary mineral phases control dissolved concentrations of Mn, Fe and PO43--tot. Dissolved As is influenced by the amount of Hfo, pH and PO43--tot as a competing ion. Laboratory studies suggest that oxidised sediments have a higher capacity to absorb As. Monitoring of hydraulic heads and groundwater modelling illustrate a complex aquifer system with three aquifers to a depth of 250 m. Groundwater modelling studies illustrate two groundwater flowsystems: i) a deeper regional predominantly

    The indicator used to measure progress toward the Millennium Development Goal (MDG) for water is access to an improved water supply. However, improved supplies are frequently fecally contaminated in developing countries. We examined factors associated with Escherichia coli contamination of improved water supplies in rural Pisco province, Peru. A random sample of 207 households with at least one child less than 5 years old was surveyed, and water samples from the source and storage container were tested for E. coli contamination. Although over 90% of households used an improved water source, 47% of source and 43% of stored water samples were contaminated with E. coli. Pouring or using a spigot to obtain water from the storage container instead of dipping a hand or object was associated with decreased risk of contamination of stored water (adjusted prevalence ratio [aPR] = 0.58, 95% confidence interval [CI] = 0.42, 0.80). Container cleanliness (aPR = 0.67, 95% CI = 0.45, 1.00) and correct handwashing technique (aPR = 0.62, 95% CI = 0.42, 0.90) were also associated with decreased contamination risk. These findings highlighted the limitations of improved water supplies as an indicator of safe water access. To ensure water safety in the home, household water treatment and improved hygiene, water handling, and storage practices should be promoted. PMID:26195455

    Background: Excessive fluoride in drinking water causes dental, skeletal and non-skeletal fluorosis which is encountered in endemic proportions in several parts of the world. The World Health Organization (WHO) guideline value and the permissible limit of fluoride as per the Bureau of Indian Standards (BIS) is 1.5 mg/L. Studies showed that withdrawal of sources identified for fluoride, often leads to reduction of fluoride in the body fluids (re-testing urine and serum after a week or ten days) and results in the disappearance of non-skeletal fluorosis within a short duration of 10-15 days. Objective: To determine the prevalence of signs and symptoms of suspected dental, skeletal and non-skeletal fluorosis along with food habits, addictions and use of fluoride-containing toothpaste among participants taking water with fluoride concentration above permissible limit and to assess the changes in clinical manifestations of the above participants after consumption of safe drinking water with fluoride concentration below permissible limit. Materials and Methods: A longitudinal intervention study was conducted from October 2010 to December 2011 in a village selected randomly in Purulia District of West Bengal which is endemic for fluorosis. Thirty-six families with 104 family members in the above village having history of taking unsafe water containing high level of fluoride were selected for the study. The occurrence of various dental, skeletal and non-skeletal manifestations of fluorosis along with food habits, addictions and use of fluoride-containing toothpaste among the study population was assessed; the impact of taking safe water with fluoride concentration below permissible limit from a supplied community filter on these clinical manifestations was studied by follow-up examination of the above participants for six months. The data obtained is compared with the collected data from the baseline survey. Results: The prevalence of signs and symptoms of dental, skeletal

    The goals of environmental legislation and associated regulations are to protect public health, natural resources, and ecosystems. In this context, monitoring programs should provide timely and relevant information so that the regulatory community can implement legislation in a cost-effective and efficient manner. The Safe Drinking Water Act (SDWA) of 1974 attempts to ensure that public water systems (PWSs) supply safe water to its consumers. As is the case with many other federal environmental statutes, SDWA monitoring has been implemented in relatively uniform fashion across the United States. In this three part series, spatial and temporal patterns in water quality data are utilized to develop, compare, and evaluate the economic performance of alternative place-based monitoring approaches to current monitoring practice. Part II: Several factors affect the performance of monitoring strategies, including: measurable objectives, required precision in estimates, acceptable confidence levels of such estimates, available budget for sampling. In this paper, we develop place-based monitoring strategies based on extensive analysis of available historical water quality data (1960-1994) of 19 Iowa community water systems. These systems supply potable water to over 350,000 people. In the context of drinking water, the objective is to protect public health by utilizing monitoring resources to characterize contaminants that are detectable, and are close to exceeding health standards. A place-based monitoring strategy was developed in which contaminants were selected based on their historical occurrence, rather than their appearance on the SDWA contaminant list. In a subset of the water systems, the temporal frequency of monitoring for one ubiquitous contaminant, nitrate, was tailored to patterns in its historical occurrence and concentration. Three sampling allocation models (linear, quadratic, and cubic) based on historic patterns in peak occurrence were developed and

    Arsenic is naturally found in surface and ground waters and the inorganic forms of arsenic are the most toxic forms. The adverse health effects of arsenic may involve the respiratory, gastrointestinal, cardiovascular, nervous, and haematopoietic systems. Arsenic contamination in drinking water is a global problem widely seen in Bangladesh and West Bengal of the Indian sub continent. As there is a great demand for field test kits due to the anticipated reduction of the US EPA arsenic standard from 50ppb to 10ppb a field kit which offers rapid, simple and safe method for precise estimation of arsenic at 10ppb in drinking water samples is developed. Field methods, based on the mercuric-bromide-stain, consist of three different major parts, which are carried out stepwise. The first part of the procedure is to remove serious interference caused by hydrogen sulphide. In commercially available kits either the sulphide is oxidized to sulphate and the excess oxidizing reagent removed prior to the hydride generation step or, the hydrogen sulphide is filtered out by passing the gas stream through a filter impregnated with lead acetate during the hydride generation step. The present method employs cupric chloride in combination with ferric chloride or Fentonis reagent for the removal of hydrogen sulphide, which is rapid, simple and more efficient. Other interferences at this step of the analyses are normally not expected for drinking water analysis. In the second step, the generation of the arsine gas involves the classical way of using zinc metal and hydrochloric acid, which produce the enascenti hydrogen, which is the actual reducing agent. Hydrochloric acid can be replaced by sulfamic acid, which is solid and avoids a major disadvantage of having to handle a corrosive liquid in the field. The arsine gas produces a yellowish spot on the reagent paper. Depending on the arsenic content, either, Yellow n H (HgBr)2 As (10-50ppb), Brown n (HgBr)3 As (50-100ppb) or Black n Hg3 As2

  7. Improving the performance of US Environmental Protection Agency Method 300.1 for monitoring drinking water compliance.

    In 1998, the United States Environmental Protection Agency (EPA) promulgated the maximum contaminant level (MCL) for bromate in drinking water at 10 microg/l, and the method for compliance monitoring of bromate in drinking water was established under Stage 1 of the Disinfectants/Disinfection By-Products Rule (D/DBP) as EPA Method 300.1. In January 2002, the United States Food and Drug Administration (FDA) regulated the bromate concentration in bottled waters at 10 microg/l. EPA anticipates proposing additional methods, which have improved performance for bromate monitoring, in addition to EPA Method 300.1, in the Stage 2 DBP Rule. Until the Stage 2 Rule is promulgated, EPA Method 300.1 will continue to be the only method approved for compliance monitoring of bromate. This manuscript describes the work completed at EPA's Technical Support Center (TSC) to assess the performance of recently developed suppressor technologies toward improving the trace level performance of EPA Method 300.1, specifically for the analysis of trace levels of bromate in high ionic matrices. Three different types of Dionex suppressors were evaluated. The baseline noise, return to baseline after the water dip, detection limits, precision and accuracy, and advantages/disadvantages of each suppressor are discussed. Performance data for the three different suppressors indicates that chemical suppression of the eluent, using the AMMS III suppressor, is the most effective means to reduce baseline noise, resulting in the best resolution and the lowest bromate detection limits, even when a high ionic matrix is analyzed. Incorporation of the AMMS III suppressor improves the performance of EPA Method 300.1 at and below 5.0 microg/l and is a quick way for laboratories to improve their bromate compliance monitoring.

The Safe Drinking Water Act (SDWA) of 1974 attempts to ensure that public water systems (PWSs) supply safe water to its consumers. As is the case with many other federal environmental statutes, SDWA monitoring has been implemented in relatively uniform fashion across the USA. In this three part series, we present over 30 years of evidence to demonstrate unique patterns in water quality contaminants over space and time, develop alternative place-based monitoring approaches that exploit such patterns, and evaluate the economic performance of such approaches to current monitoring practice. Part III: Place-based (PBA) and current SDWA monitoring approaches were implemented on test datasets (1995-2001) from 19 water systems and evaluated based on the following criteria: percent of total detections, percent detections above threshold values (e.g. 20, 50, 90% of MCL), and cost. The PBA outperformed the current SDWA monitoring requirements in terms of total detections, missed only a small proportion of detections below the MCL, and captured all detections above 50% of the MCL. Essentially the same information obtained from current compliance monitoring requirements can be gained at approximately one-eighth the cost by implementing the PBA. Temporal sampling strategies were implemented on test datasets (1995-2001) from four water systems and evaluated by the following criteria: parameter estimation, percent deviation from "true" 90th, 95th, and 99th percentiles, and number of samples versus accuracy of the estimate. Non event-based (NEB) strategies were superior in estimating percentiles 1-50, but underestimated the higher percentiles. Event-based strategies were

    One of the United Nations Millennium Development Goals is to reduce to half by 2015 the number of people, worldwide, who lack access to safe water. Due to the numerous deaths and illnesses caused by waterborne pathogens, various household water treatment devices and safe storage technologies have been developed to treat and manage water at the household level. The new approaches that are continually being examined need to be durable, lower in overall cost and more effective in the removal of the contaminants. In this study, an extensive literature survey was conducted to regroup various household treatment devices that are suitable for the inexpensive treatment of water on a household basis. The survey has resulted in the selection of four household treatment devices: the biosand filter (BSF), bucket filter (BF), ceramic candle filter (CCF) and the silver-impregnated porous pot filter (SIPP). The first three filters were manufactured in a Tshwane University of Technology workshop, using modified designs reported in literature. The SIPP filter is a product of the Tshwane University of Technology. The performance of the four filters was evaluated in terms of flow rate, physicochemical contaminant (turbidity, fluorides, phosphates, chlorophyll a, magnesium, calcium and nitrates) and microbial contaminant ( Escherichia coli, Vibrio cholerae, Salmonella typhimurium, Shigella dysenteriae) removals. The flow rates obtained during the study period were within the recommended limits (171 l/h, 167 l/h, 6.4 l/h and 3.5 l/h for the BSF, BF, CCF and SIPP, respectively). Using standard methods, the results of the preliminary laboratory and field studies with spiked and environmental water samples indicated that all filters decreased the concentrations of contaminants in test water sources. The most efficiently removed chemical contaminant in spiked water was fluoride (99.9%) and the poorest removal efficiency was noted for magnesium (26-56%). A higher performance in chemical

    Endemic fluorosis was detected in 31 villages in the Dhar district of Madhya Pradesh, Central India. Out of the 109 drinking water sources that were analyzed, about 67 % were found to contain high concentration of fluoride above the permissible level of 1.0 mg/l. Dental fluorosis among the primary school children in the age between 8 and 15 served as primary indicator for fluoride intoxication among the children. Urinary fluoride levels among the adults were found to be correlated with drinking water fluoride in 10 villages affected by fluoride. Intervention in the form of alternate safe water supply in five villages showed significant reduction in the urinary fluoride concentration when compared to the control village. Urinary fluoride serves as an excellent marker for assessing the effectiveness of intervention program in the fluoride-affected villages.

    2011-01-01

    The quality of drinking water in the United States has continued to improve over the past 40 years. The formation of the U.S. Environmental Protection Agency (USEPA) in 1971, the passage of the initial Safe Drinking Water Act (SDWA, PL 93-523) in 1974, and the passage of the 1996 SDWA Amendments (PL 104-208) represent significant progress in drinking water quality. While the widespread adoption of filtration and disinfection in the early 1900s virtually eliminated waterborne typhoid fever, some residual risks still remained 40 years ago. These national regulatory developments compelled USEPA and the drinking water community to address these remaining risks in drinking water and optimize risk reduction for the public.

    Recent studies have shown a decrease in the concentration of pesticides, pharmaceuticals and personal care products (PCPs) in water after treatment. A possible explanation for this phenomenon is that these compounds may adhere to the sludge; however, investigation of these compounds in drinking water treatment sludge has been scarce. The sludge generated by drinking water treatment plants during flocculation and decantation steps should get some special attention not only because it has been classified as non-inert waste but also because it is a very complex matrix, consisting essentially of inorganic (sand, argil and silt) and organic (humic substances) compounds. In the first step of this study, three QuEChERS methods were used, and then compared, for the extraction of pesticides (atrazine, simazine, clomazone and tebuconazole), pharmaceuticals (amitriptyline, caffeine, diclofenac and ibuprofen) and PCPs (methylparaben, propylparaben, triclocarban and bisphenol A) from drinking water treatment sludge. Afterwards, the study of different sorbents in the dispersive solid phase extraction (d-SPE) step was evaluated. Finally, a new QuEChERS method employing chitin, obtained from shrimp shell waste, was performed in the d-SPE step. After having been optimized, the method showed limits of quantification (LOQ) between 1 and 50 μg kg(-1) and the analytical curves showed r values higher than 0.98, when liquid chromatography tandem mass spectrometry was employed. Recoveries ranged between 50 and 120% with RSD≤15%. The matrix effect was evaluated and compensated with matrix-matched calibration. The method was applied to drinking water treatment sludge samples and methylparaben and tebuconazole were found in concentration

    This report contains a series of tables summarizing the thermodynamic properties of aqueous carbonate complexes and solid carbonate phases of the following elements: arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), nickel (Ni) thallium (Tl), uranium (U) and zinc (Zn). Most of these elements are potentially hazardous as defined by extant primary drinking water standards of the United States Environmental Protection Agency (EPA). The remainder are not considered hazardous, but are either listed by EPA under secondary standards, or because they can adversely affect drinking water quality. Additional tables are included giving the thermodynamic properties for carbonates of the alkali metal and alkali earth elements, sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), and strontium (Sr), because of their value in developing correlative models to estimate the thermodynamic properties of carbonate minerals for which no such data currently exist. The purpose in creating the tables in this report is to provide future investigators with a convenient source for selecting and tracing the sources of thermodynamic data of the above listed elements for use in modeling their geochemical behavior in “underground sources of drinking water” (USDW). The incentive for doing so lies with a heightened concern over the potential consequences of the proposed capture and storage of carbon dioxide (CO2) generated by fossil fuel fired power plants in deep subsurface reservoirs. If CO2 were to leak from such reservoirs, it could migrate upward and contaminate USDWs with undesirable, but undetermined, consequences to water quality. The EPA, Office of Research and Development, through an Interagency Agreement with the U.S. Department of Energy at the Lawrence Berkeley National Laboratory, funded the preparation of this report.

    Washington River Protection Solutions, LLC (WRPS) has faced significant project management challenges in managing Davis-Bacon construction work that meets contractually required small business goals. The unique challenge is to provide contracting opportunities to multiple small business construction subcontractors while performing high hazard work in a safe and productive manner. Previous to the Washington River Protection Solutions, LLC contract, Construction work at the Hanford Tank Farms was contracted to large companies, while current Department of Energy (DOE) Contracts typically emphasize small business awards. As an integral part of Nuclear Project Management at Hanford Tank Farms, construction involves removal of old equipment and structures and installation of new infrastructure to support waste retrieval and waste feed delivery to the Waste Treatment Plant. Utilizing the optimum construction approach ensures that the contractors responsible for this work are successful in meeting safety, quality, cost and schedule objectives while working in a very hazardous environment. This paper describes the successful transition from a traditional project delivery method that utilized a large business general contractor and subcontractors to a new project construction management model that is more oriented to small businesses. Construction has selected the Agency Construction Management Method. This method was implemented in the first quarter of Fiscal Year (FY) 2009, where Construction Management is performed by substantially home office resources from the URS Northwest Office in Richland, Washington. The Agency Method has allowed WRPS to provide proven Construction Managers and Field Leads to mentor and direct small business contractors, thus providing expertise and assurance of a successful project. Construction execution contracts are subcontracted directly by WRPS to small or disadvantaged contractors that are mentored and supported by DRS personnel. Each small

    Drinking water represents a major pathway of trace elements into the human body. As such, groundwaters, the chemistry of which reflect water/rock interaction, can be a source of trace elements which will have a marked health effect on humans consuming them. Health problems associated with the consumption of groundwater enriched in various elements and compounds have been recorded for many years. For example, high-arsenic groundwaters used for public water supply were first associated with harmful health effects as early as 1917 in Córdoba Province in Argentina, where the local population suffered from skin disorders. Subsequently, in the 1960s consumption of high-arsenic groundwaters was identified as a factor in the aetiology of "black foot disease", an endemic vascular disease, in Taiwan. However, it is problems associated with the very high-arsenic groundwaters of the highly populous Ganges delta area of Bangladesh and West Bengal that has more recently highlighted the health problem of consuming high-arsenic waters. The most obvious problems of excess arsenic consumption through drinking water are arsenical skin lesions, the severity of which being generally correlated with arsenic content of the water. A high incidence of cancers of the skin, bladder and other organs has been recorded in the high-arsenic drinking water areas of the world. A high incidence of vascular disease, found in the arsenic-rich area of Taiwan, has also been shown to occur in Bangladesh. In addition, it has been suggested that high arsenic in drinking water results in increased incidence of diabetes mellitus. Fluorine is another element long recognised as having a major effect on the well-being of humans. Consumption of high-fluorine waters were first identified as having a detrimental effect on teeth in the 1920s and 30s. It was subsequently shown that where fluorine is present in drinking waters at concentrations of around 0.5 to 1 mg/L it can have beneficial effects on humans

    Exploitation of groundwater from shallow, high prolific Holocene sedimentary aquifers has been a main element for achieving safe drinking water and food security in Bangladesh. However, the presence of elevated levels of geogenic arsenic (As) in these aquifers has undermined this success. Except for targeting safe aquifers through installations of tubewells to greater depth, no mitigation option has been successfully implemented on a larger scale. The objective of this study has been to characterise the hydrostratigraphy, groundwater flow patterns, the hydraulic properties to assess the vulnerability of low-arsenic aquifers at Matlab, in south-eastern Bangladesh, one of the worst arsenic-affected areas of the country. Groundwater modelling, conventional pumping test using multilevel piezometers, hydraulic head monitoring in piezometer nests, 14C dating of groundwater and assessment of groundwater abstraction were used. A model comprising of three aquifers covering the top 250 m of the model domain showed the best fit for the calibration evaluation criteria. Irrigation wells in the Matlab area are mostly installed in clusters and account for most of the groundwater abstraction. Even though the hydraulic heads are affected locally by seasonal pumping, the aquifer system is fully recharged from the monsoonal replenishment. Groundwater simulations demonstrated the presence of deep regional flow systems with recharge areas in the eastern, hilly part of Bangladesh and shallow small local flow systems driven by local topography. Based on modelling results and 14C groundwater data, it can be concluded that the natural local flow systems reach a depth of 30 m b.g.l. in the study area. A downward vertical gradient of roughly 0.01 down to 200 m b.g.l. was observed and reproduced by calibrated models. The vertical gradient is mainly the result of the aquifer system and properties rather than abstraction rate, which is too limited at depth to make an imprint. Although

    US Environmental Protection Agency (EPA) Method 331 determines perchlorate in drinking water using non-suppressed ion chromatography with tandem mass spectrometry. This study reports the results of calibration and recovery studies in reagent water, as well as of a recovery study in simulated drinking water (i.e., total dissolved solids are 500 mg/mL each of chloride, sulfate, and bicarbonate). The perchlorate concentrations in the study ranged from 0.05 to 64 ng/mL. At 95% confidence, the Hubaux-Vos detection limit (H-V DL) was 0.04 ng/mL for the calibration study and the simulated-drinking-water recovery study, and 0.03 ng/mL for the reagent-water recovery study. The lowest concentration minimum reporting level was 0.03 ng/mL for reagent water and 0.0 7 ng/mL for simulated drinking water, again at 95% confidence.

    Natural disasters can be devastating to local water supplies affecting millions of people. Disaster recovery plans and water industry collaboration during emergencies protect consumers from contaminated drinking water supplies and help facilitate the repair of public water systems. Prior to an event, utilities and municipalities can use "What if"? scenarios to develop emergency operation, response, and recovery plans designed to reduce the severity of damage and destruction. Government agencies including the EPA are planning ahead to provide temporary supplies of potable water and small drinking water treatment technologies to communities as an integral part of emergency response activities that will ensure clean and safe drinking water.

    Objective To examine factors associated with suffering harm from another person's alcohol consumption and explore how suffering such harms relate to feelings of safety in nightlife. Design Cross-sectional opportunistic survey (Global Drug Survey) using an online anonymous questionnaire in 11 languages promoted through newspapers, magazines and social media. Subjects Individuals (participating November 2014–January 2015) aged 18–34 years, reporting alcohol consumption in the past 12 months and resident in a country providing ≥250 respondents (n=21 countries; 63 725 respondents). Main outcome measures Harms suffered due to others’ drinking in the past 12 months, feelings of safety on nights out (on the way out, in bars/pubs, in nightclubs and when travelling home) and knowledge of over-serving laws and their implementation. Results In the past 12 months, >40% of respondents suffered at least one aggressive (physical, verbal or sexual assault) harm and 59.5% any harm caused by someone drunk. Suffering each category of harm was higher in younger respondents and those with more harmful alcohol consumption patterns. Men were more likely than women to have suffered physical assault (9.2% vs 4.7; p<0.001), with women much more likely to suffer sexual assault or harassment (15.3% vs 2.5%; p<0.001). Women were more likely to feel unsafe in all nightlife settings, with 40.8% typically feeling unsafe on the way home. In all settings, feeling unsafe increased with experiencing more categories of aggressive harm by a drunk person. Only 25.7% of respondents resident in countries with restrictions on selling alcohol to drunks knew about such laws and 75.8% believed that drunks usually get served alcohol. Conclusions Harms from others’ drinking are a threat to people's health and well-being. Public health bodies must ensure that such harms are reflected in measures of the societal costs of alcohol, and must advocate for the enforcement of legislation designed to

    Safe drinking-water supplies are critical to maintaining and preserving public health. Although the Nation's drinking water is generally safe, natural and introduced contaminants in water supplies throughout the country have adversely affected human health. This new U.S. Geological Survey (USGS) initiative will provide information on the vulnerability of water supplies to be used by water-supply and regulatory agencies who must balance water-supply protection with the wise use of public funds. Using the results of the initiative, they will be better able to focus on the supplies most at risk and the variability of contaminants of most concern, and so address the mandates of the Safe Drinking Water Act. With its store of geologic, hydrologic, and land use and land cover data and its network of information in every State, the USGS can help to identify potential sources of contamination, delineate source areas, determine the vulnerability of waters to potential contamination, and evaluate strategies being used to protect source waters in light of the scientific information available. Many recent and ongoing studies by the USGS concern drinking-water issues. This fact sheet highlights four particular studies begun under the Drinking Water Initiative.

    Jacangelo, Joseph G; Askenaizer, Daniel J; Schwab, Kellogg

    2006-01-01

    Regulations are one of the primary drivers for research on contaminants in drinking water in the United States. Since the original Safe Drinking Water Act (SDWA), enacted in 1974, the United States Environmental Protection Agency (USEPA) has developed a series of drinking water regulations. These regulations are focused on protecting public health. When evaluating available information on whether or not to regulate a constituent in drinking water, USEPA considers available information on health effects and occurrence of the constituent. The authors provide their view of the research needed for these contaminants. For inorganics, more data are needed on perchlorate. For organics, greater treatment and health effects information is warranted for N-nitrosodimethylamine (NDMA), methyl tertiary butyl ether (MTBE) and pharmaceuticals and personal care products. Finally, more research is needed on analytical methods for noroviruses and other emerging pathogens.

    The biggest users of GRID technologies came from the science and technology communities. These consist of government, industry and academia (national and international). The NASA GRID is moving into a higher technology readiness level (TRL) today; and as a joint effort among these leaders within government, academia, and industry, the NASA GRID plans to extend availability to enable scientists and engineers across these geographical boundaries collaborate to solve important problems facing the world in the 21 st century. In order to enable NASA programs and missions to use IPG resources for program and mission design, the IPG capabilities needs to be accessible from inside the NASA center networks. However, because different NASA centers maintain different security domains, the GRID penetration across different firewalls is a concern for center security people. This is the reason why some IPG resources are been separated from the NASA center network. Also, because of the center network security and ITAR concerns, the NASA IPG resource owner may not have full control over who can access remotely from outside the NASA center. In order to obtain organizational approval for secured remote access, the IPG infrastructure needs to be adapted to work with the NASA business process. Improvements need to be made before the IPG can be used for NASA program and mission development. The Secured Advanced Federated Environment (SAFE) technology is designed to provide federated security across NASA center and NASA partner's security domains. Instead of one giant center firewall which can be difficult to modify for different GRID applications, the SAFE "micro security domain" provide large number of professionally managed "micro firewalls" that can allow NASA centers to accept remote IPG access without the worry of damaging other center resources. The SAFE policy-driven capability-based federated security mechanism can enable joint organizational and resource owner approved remote

  3. Drinking water standards for radionuclides: the dilemma and a possible resolution.

    PubMed

    Kocher, D C

    2001-05-01

    The U.S. Environmental Protection Agency (EPA) is undertaking a revision of existing standards for radionuclides in drinking water. The Safe Drinking Water Act specifies that any revision "shall maintain or provide for greater protection of the health of persons." This provision appears to require that existing standards (maximum contaminant levels, MCLs) cannot be relaxed. Such a requirement presents a dilemma for two reasons. First, EPA has shown that the MCL for radium was not cost-effective. Second, MCLs for beta/gamma-emitting radionuclides incorporate outdated approaches to estimating dose from ingestion of radionuclides and, thus, appear to violate provisions of the Safe Drinking Water Act concerning the use of sound science in setting standards. We suggest that this dilemma can be resolved based on an argument that the standard for protection of public health mandated by the Safe Drinking Water Act is one of applying best-available technology for removal of contaminants from drinking water at a reasonable cost, not one of meeting previously established MCLs.

  8. Drinking water disinfection byproducts: review and approach to toxicity evaluation.

    PubMed

    Boorman, G A

    1999-02-01

    There is widespread potential for human exposure to disinfection byproducts (DBPs) in drinking water because everyone drinks, bathes, cooks, and cleans with water. The need for clean and safe water led the U.S. Congress to pass the Safe Drinking Water Act more than 20 years ago in 1974. In 1976, chloroform, a trihalomethane (THM) and a principal DBP, was shown to be carcinogenic in rodents. This prompted the U.S. Environmental Protection Agency (U.S. EPA) in 1979 to develop a drinking water rule that would provide guidance on the levels of THMs allowed in drinking water. Further concern was raised by epidemiology studies suggesting a weak association between the consumption of chlorinated drinking water and the occurrence of bladder, colon, and rectal cancer. In 1992 the U.S. EPA initiated a negotiated rulemaking to evaluate the need for additional controls for microbial pathogens and DBPs. The goal was to develop an approach that would reduce the level of exposure from disinfectants and DBPs without undermining the control of microbial pathogens. The product of these deliberations was a proposed stage 1 DBP rule. It was agreed that additional information was necessary on how to optimize the use of disinfectants while maintaining control of pathogens before further controls to reduce exposure beyond stage 1 were warranted. In response to this need, the U.S. EPA developed a 5-year research plan to support the development of the longer term rules to control microbial pathogens and DBPs. A considerable body of toxicologic data has been developed on DBPs that occur in the drinking water, but the main emphasis has been on THMs. Given the complexity of the problem and the need for additional data to support the drinking water DBP rules, the U.S. EPA, the National Institute of Environmental Health Sciences, and the U.S. Army are working together to develop a comprehensive biologic and mechanistic DBP database. Selected DBPs will be tested using 2-year toxicity and

    NASA Technical Reports Server (NTRS)

    2004-01-01

    A mineral identification tool that was developed for NASA's Mars Rover Technology Development program is now serving as a powerful tool for U.S. law enforcement agencies and military personnel to identify suspicious liquid and solid substances. The tool can measure unknown substances through glass and plastic packaging materials with the RamanProbe(TradeMark) focused fiber-optic probe. The probe length can be extended up to 200 meters to enable users to analyze potentially dangerous substances at a safe distance. In many cases, the spectrometer and personnel are kept in a safe zone while the probe is positioned next to the sample being analyzed. Being able to identify chemicals in remote locations also saves users time and labor, since otherwise the samples would need to be collected, transported, and prepared prior to measurement in the laboratory.

    Along the intense industrialization of the Ruhr valley (Germany), the River Ruhr became increasingly polluted. Over time, using it for recreational purposes became a serious health hazard and bathing was banned due to chemical and microbiological risks. The purpose of the collaborative project "Safe Ruhr" was to verify the current status and to provide a scientific basis for lifting the bathing ban. As the river also provides a raw water source for drinking water production, it was investigated how well the treatment procedures control possible hygienic risks. As study area, the barrier Lake Baldeney was chosen as it embraces earlier bathing sites and tributes to river bank filtration water for drinking water treatment plants. The hygienic condition of the river water was determined over 18 months by measuring general physical, chemical and microbiological water quality parameters including fecal indicators, bacterial obligate and facultative pathogens, parasitic protozoa, enteric viruses and schistosome parasites (Trichobilharzia). Samples were taken at eight locations including sites before and after receiving the discharge of stormwater and treated wastewater, potential future bathing sites and a raw water abstraction point for potable water production. In summary, for all investigated physico-chemical parameters no significant difference between the eight investigated sampling locations on a distinct sampling date were observed. This study focused on hygienically relevant bacteria and parasitic protozoa. Fecal indicators, Escherichia coli, intestinal enterococci and Clostridium perfringens as well as coliform bacteria were detected in 94-100% of the water samples. Enteric pathogens, including Campylobacter spp. and Salmonella enterica, were isolated from 33% and 28% of the samples, respectively, in relatively low concentrations. Among the environmental facultative pathogens, P. aeruginosa was detected at a high frequency of 82% of all samples, but in low

People with compromised immune systems are vulnerable to infection from the parasite cryptosporidium in the water supply. Currently, there is no effective treatment for the condition. On June 15, 1995, the Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) published guidelines to inform people how to avoid infection with cryptosporidium. The Council publicly supports these guidelines about home filtration, boiling water, and bottled water.

    Drinking water regulations under the Final Coliform Rule require that total coliform-positive drinking water samples be examined for the presence of Escherichia coli or fecal coliforms. The current U.S. Environmental Protection Agency-approved membrane filter (MF) method for E. coli requires two media, an MF transfer, and a total incubation time of 28 h. A newly developed MF method, the MI agar method, containing indoxyl-beta-D-glucuronide and 4-methylumbelliferyl-beta-D-galactopyranoside for the simultaneous detection of E. coli and total coliforms, respectively, by means of their specific enzyme reactions, was compared with the approved method by the use of wastewater-spiked tap water samples. Overall, weighted analysis of variance (significance level, 0.05) showed that the new medium recoveries of total coliforms and E. coli were significantly higher than those of mEndo agar and nutrient agar plus MUG (4-methylumbelliferyl-beta-D-glucuronide), respectively, and the background counts were significantly lower than those of mEndo agar (< 5%). Generally, the tap water source, overall chlorine level, wastewater source, granular activated carbon treatment of the tap water, and method of grouping data by E. coli count for statistical analysis did not affect the performance of the new medium.

  15. Burden of Cancer from Chemicals in North Carolina Drinking Water

    NASA Astrophysics Data System (ADS)

    DeFelice, N.

    2013-12-01

    Monitoring programs required by the U.S. Safe Drinking Water Act (SDWA) currently do not consider potential differences in chemical exposure patterns and human health risks. Rather, U.S. agencies establish monitoring requirements based on the type of water system and the number of people the system serves; within categories of systems, all potentially carcinogenic chemicals must be monitored with equal frequency, regardless of the potential level of risk these chemicals pose. To inform future policies concerning contaminant monitoring under the SDWA, we examined the potential health threats in North Carolina from the 34 carcinogenic chemicals covered under the SDWA. We analyzed reported contaminant concentration data for all community water systems (CWSs) for the years 1998-2011. We employed an attributable fraction approach that uses probabilistic inputs to evaluate the percent of cancer cases that may be attributable to chemical exposure in drinking water. We found that cancer risks are dominated by 3 of the 34 chemicals and chemical classes (total trihalomethanes (TTHMs), arsenic and gross alpha particles); all other chemicals contribute to less than one cancer case per year in the state. We showed that around 840 cases of cancer annually (2% of annual cancer cases) are attributable to contaminated drinking water. The majority cases are due to TTHMs, arsenic and gross alpha particles, which contributed 810 (95% CI 560-1,280), 14 (95% CI 3 -32), and 13 (95% CI 2-48) cases, respectively. Sixty-seven counties had annual cancer rates higher than 1 in 10,000 attributable to community water systems. Annual cancer rate attributable to chemicals found in drinking water that are regulated under the safe drinking water act.

    The role that deficient institutional relationships have played in aggravating drinking water incidents over the last 30 years has been identified in several inquiries of high profile drinking water safety events, peer-reviewed articles and media reports. These indicate that collaboration between water utilities and public health agencies (PHAs) during normal operations, and in emergencies, needs improvement. Here, critical elements of these interagency collaborations, that can be integrated within the corporate risk management structures of water utilities and PHAs alike, were identified using a grounded theory approach and 51 semi-structured interviews with utility and PHA staff. Core determinants of effective interagency relationships are discussed. Intentionally maintained functional relationships represent a key ingredient in assuring the delivery of safe, high quality drinking water.

  20. Role of detection limits in drinking water regulation.

    PubMed

    Calder, Ryan S D; Schmitt, Ketra A

    2010-11-01

    Some commentators on environmental science and policy have claimed that advances in analytical chemistry, reflected by an ability to detect contaminants at ever-decreasing concentrations, lead to regulations stricter than justified by available toxicological data. We evaluate this claim in the context of drinking water regulation, with respect to contaminants regulated under the Safe Drinking Water Act (SDWA). We examine the relationships between historical and present maximum contaminant levels and goals in the greater context of detection capability and evaluate the extent to which different aspects of the regulatory apparatus (i.e., analytical capability, cost-benefit analysis, analysis of competing risks, and available toxicological data) influence the regulatory process. Our findings do not support the claim that decreases in detection limit lead to more stringent regulation in the context of drinking water regulation in the United States. Further, based on our analysis of the National Primary Drinking Water Regulation and existing United States Environmental Protection Agency approaches to establishing the practical quantifiable level, we conclude that in the absence of changes to the underlying toxicological model, regulatory revision is unlikely.

    Objective: The market and degree of consumption of energy drinks have exponentially expanded while studies that assess their psychological effects and impact on quality of life remain in the early stages, albeit on the rise. This review aims to examine the literature for evidence of the psychological effects of energy drinks and their impact on the sense of well-being and quality of life. Methods: Studies were identified through Pubmed, Medline, and PsycINFO searches from the dates of 1990 to 2011, published in English, using the keywords energy or tonic drinks, psychological effects, caffeine and cognitive functions, mood, sleep, quality of life, well-being, and mental illness. Three authors agreed independently on including 41 studies that met specific selection criteria. Results: The literature reveals that people most commonly consume energy drinks to promote wakefulness, to increase energy, and to enhance the experience of alcohol intoxication. A number of studies reveal that individuals who consume energy drinks with alcohol were more inclined to be involved in risk-taking behaviors. There was also excessive daytime sleepiness the day following energy drink consumption. Contrary to expectations, the impact of energy drinks on quality of life and well-being was equivocal. Conclusions: Energy drinks have mixed psychological and well-being effects. There is a need to investigate the different contexts in which energy drinks are consumed and the impact on mental health, especially in the psychiatrically ill. PMID:22347688

    This study aimed to describe the households’ choices of drinking water sources, and evaluate the risk of human exposure to heavy metals via different drinking water sources in Chenzhou City of Hunan Province, Southern China. A cross-sectional face-to-face survey of 192 householders in MaTian and ZhuDui village was conducted. The concentrations of heavy metals in their drinking water sources were analyzed. Carcinogenic and non-carcinogenic risk assessment was performed according to the method recommended by the United States Environmental Protection Agency. In total, 52.60% of the households used hand-pressed well water, and 34.89% used barreled water for drinking. In total, 6.67% of the water samples exceeded the Chinese drinking water standards. The total health risk of five metals is 5.20 × 10−9~3.62 × 10−5. The total health risk of five metals was at acceptable levels for drinking water sources. However, the total risk of using hand-pressed well water’s highest value is 6961 times higher than the risk of using tap water. Household income level was significantly associated with drinking water choices. Arsenic (As) and lead (Pb) are priority controlled pollutants in this region. Using safe drinking water (tap water, barreled water and so on) can remarkably reduce the risk of ingesting heavy metals. PMID:26569281

    2015-05-01

    Accounting for fecal contamination of drinking water sources is an important step in improving monitoring of global access to safe drinking water. Fecal contamination varies with time while its monitoring is often infrequent. We sought to understand seasonal trends in fecal contamination to guide best practices to capture seasonal variation and ascertain the extent to which the results of a single sample may overestimate compliance with health guidelines. The findings from 22 studies from developing countries written in English and identified through a systematic review were analyzed. Fecal contamination in improved drinking water sources was shown to follow a statistically significant seasonal trend of greater contamination during the wet season (p<0.001). This trend was consistent across fecal indicator bacteria, five source types, twelve Köppen-Geiger climate zones, and across both rural and urban areas. Guidance on seasonally representative water quality monitoring by the World Health Organization and national water quality agencies could lead to improved assessments of access to safe drinking water.

    Making appropriate recommendations for safe drinking behavior among different age groups requires understanding of differences between young and older adults in following them. The purpose of this study was to investigate how drinking behavior in terms of drinking speed and bolus size differs between young and older adults following instructions to change drinking rate. Thirty young (mean age 24.7 years) and 30 older (mean age 66.9 years) healthy female participants were recruited. All participants drank water under different drinking instructions: "as they normally would", "as quickly as is comfortably possible", and "slowly". Results showed that when asked to drink quickly, both age groups increased drinking speed to a similar extent. When asked to drink slowly, older adults were unable to slow their drinking rate as much as young adults (P < .001). When drinking slowly, older adults had significantly larger bolus size than young adults'. These suggest that in a healthcare setting, the often prescribed advice to "drinking slowly" may be insufficient precaution for older patients. Prudence is suggested to carefully observe patients drinking after they've been asked to drink slowly, before making a clinical judgment if additional, more specific strategies may be indicated.

  3. US Environmental Protection Agency Method 314.1, an automated sample preconcentration/matrix elimination suppressed conductivity method for the analysis of trace levels (0.50 microg/L) of perchlorate in drinking water.

    Since 1997 there has been increasing interest in the development of analytical methods for the analysis of perchlorate. The US Environmental Protection Agency (EPA) Method 314.0, which was used during the first Unregulated Contaminant Monitoring Regulation (UCMR) cycle, supports a method reporting limit (MRL) of 4.0 microg/L. The non-selective nature of conductivity detection, combined with very high ionic strength matrices, can create conditions that make the determination of perchlorate difficult. The objective of this work was to develop an automated, suppressed conductivity method with improved sensitivity for use in the second UCMR cycle. The new method, EPA Method 314.1, uses a 35 mm x 4 mm cryptand concentrator column in the sample loop position to concentrate perchlorate from a 2 mL sample volume, which is subsequently rinsed with 10 mM NaOH to remove interfering anions. The cryptand concentrator column is combined with a primary AS16 analytical column and a confirmation AS20 analytical column. Unique characteristics of the cryptand column allow perchlorate to be desorbed from the cryptand trap and refocused on the head of the guard column for subsequent separation and analysis. EPA Method 314.1 has a perchlorate lowest concentration minimum reporting level (LCMRL) of 0.13 microg/L in both drinking water and laboratory synthetic sample matrices (LSSM) containing up to 1,000 microg/L each of chloride, bicarbonate and sulfate.

    The impact of social anxiety on negative alcohol-related behaviors among college students has been studied extensively. Drinking motives are considered the most proximal indicator of college student drinking behavior. The current study examined the mediating role of drinking motives in the relationship that social anxiety symptoms have with problematic (alcohol consumption, harmful drinking, and negative consequences) and safe (protective behavioral strategies) drinking behaviors. Participants were 532 undergraduates who completed measures of social anxiety, drinking motives, alcohol use, harmful drinking patterns, negative consequences of alcohol use, and protective behavioral strategy use. Our results show that students with higher levels of social anxiety symptoms who were drinking for enhancement motives reported more harmful drinking and negative consequences, and used fewer protective behavioral strategies. Thus, students who were drinking to increase their positive mood were participating in more problematic drinking patterns compared with students reporting fewer social anxiety symptoms. Further, conformity motives partially mediated the relationship between social anxiety symptoms and negative consequences. Thus, students with more symptoms of social anxiety who were drinking in order to be accepted by their peers were more likely than others to experience negative consequences. Clinical and research implications are discussed.

    Alcohol is the substance most frequently abused by children and adolescents in the United States, and its use is associated with the leading causes of death and serious injury at this age (ie, motor vehicle accidents, homicides, and suicides). Among youth who drink, the proportion who drink heavily is higher than among adult drinkers, increasing from approximately 50% in those 12 to 14 years of age to 72% among those 18 to 20 years of age. In this clinical report, the definition, epidemiology, and risk factors for binge drinking; the neurobiology of intoxication, blackouts, and hangovers; genetic considerations;and adverse outcomes are discussed. The report offers guidance for the pediatrician. As with any high-risk behavior, prevention plays a more important role than later intervention and has been shown to be more effective. In the pediatric office setting, it is important to ask every adolescent about alcohol use.

  8. The risks of drinking water

    NASA Astrophysics Data System (ADS)

    1984-04-01

    Three researchers from the Energy and Environmental Policy Center at Harvard University have come up with a new method of calculating the risk from contaminants in drinking water, one that they believe takes into account some of the uncertainties in pronouncing water safe or dangerous to drink. The new method concentrates on the risk of cancer, which authors Edmund Crouch, Richard Wilson, and Lauren Zeise believe has not been properly considered in establishing drinking water standards.Writing in the December 1983 issue of Water Resources Research, the authors state that “current [drinking water] standards for a given chemical or class of chemicals do not account for the presence of other pollutants” that could combine to create dangerous substances. According to Wilson, “Over a hundred industrial pollutants and chlorination byproducts have been found in various samples of drinking water, some of which are known carcinogens, others suspected carcinogens.” The same chlorine that solves one major health problem—the threat of bacterial disease—can thus contribute to another, according to the authors, by increasing the long-term risk of cancer. The largest risks are due to halomethanes such as chloroform and bromoform, produced as chlorine reacts with organic matter in drinking water.

  13. Proposed modifications of Environmental Protection Agency Method 1601 for detection of coliphages in drinking water, with same-day fluorescence-based detection and evaluation by the performance-based measurement system and alternative test protocol validation approaches.

    PubMed

    2010-12-01

    Coliphages are microbial indicators specified in the Ground Water Rule that can be used to monitor for potential fecal contamination of drinking water. The Total Coliform Rule specifies coliform and Escherichia coli indicators for municipal water quality testing; thus, coliphage indicator use is less common and advances in detection methodology are less frequent. Coliphages are viral structures and, compared to bacterial indicators, are more resistant to disinfection and diffuse further distances from pollution sources. Therefore, coliphage presence may serve as a better predictor of groundwater quality. This study describes Fast Phage, a 16- to 24-h presence/absence modification of U.S. Environmental Protection Agency (EPA) Method 1601 for detection of coliphages in 100 ml water. The objective of the study is to demonstrate that the somatic and male-specific coliphage modifications provide results equivalent to those of Method 1601. Five laboratories compared the modifications, featuring same-day fluorescence-based prediction, to Method 1601 by using the performance-based measurement system (PBMS) criterion. This requires a minimum 50% positive response in 10 replicates of 100-ml water samples at coliphage contamination levels of 1.3 to 1.5 PFU/100 ml. The laboratories showed that Fast Phage meets PBMS criteria with 83.5 to 92.1% correlation of the same-day rapid fluorescence-based prediction with the next-day result. Somatic coliphage PBMS data are compared to manufacturer development data that followed the EPA alternative test protocol (ATP) validation approach. Statistical analysis of the data sets indicates that PBMS utilizes fewer samples than does the ATP approach but with similar conclusions. Results support testing the coliphage modifications by using an EPA-approved national PBMS approach with collaboratively shared samples.

  1. Safe motherhood in refugee settings.

    PubMed

    Sachs, L

    1997-05-01

    The complications of pregnancy and delivery is one of the major causes of death and disease among refugee women of childbearing age. While it is difficult to obtain accurate statistics on the number of pregnant refugees worldwide, an estimated 25% of such women are pregnant at any given time. The dislocation, inadequate shelter, minimal food rations, poor sanitation, and physical danger typical of refugee life make safe motherhood almost impossible. In such situations, fertility rates tend to be extremely high, with refugee women having very large numbers of children in response to pressure on them from leaders to rebuild the population, improvements in child survival rates, and the absence of fertility-regulating information and services. Closely spaced pregnancies are thus common. The two field operations manuals created out of the 1995 Inter-Agency Symposium on Reproductive Health in Refugee Situations recommend making safe motherhood a high priority during both the emergency and stabilization phases in refugee situations.

  2. Drinking motives, drinking restraint and drinking behaviour among young adults.

    2010-02-01

    Motives to drink alcohol are widely thought to be the proximal cognitive factors involved in the decision to consume alcohol beverages. However it has also been argued that the ability to restrain drinking may be a more proximal predictor of drinking behaviour. The current study aimed to examine the relationships between drinking motives, drinking restraint and both alcohol consumption and alcohol-related problems in a sample of young adults. A sample of 221 young adults (aged 17-34 years) completed self-report measures assessing drinking behaviour, motives for drinking and drinking restraint. Multiple regression analyses revealed that coping, enhancement and social motives were related to alcohol consumption and alcohol-related problems, while Cognitive and Emotional Preoccupation with drinking was related to all criterion variables. Further, the relationship between coping motives and drinking behaviour was mediated by preoccupation with drinking. The results are discussed in light of the roles of drinking motives and drinking restraint in risky drinking among young people, and implications for prevention and early intervention are presented.

  3. Energy drinks: a review of use and safety for athletes.

    Duchan, Erin; Patel, Neil D; Feucht, Cynthia

    2010-06-01

    Energy drinks have increased in popularity in adolescents and young adults; however, concerns have been raised regarding the ingredients in energy drinks and their potential negative effects on health. Caffeine, the most physiologically active ingredient in energy drinks, is generally considered safe by the US Food and Drug Administration (FDA), although adverse effects can occur at varying amounts. Guarana, which contains caffeine in addition to small amounts of theobromine, theophylline, and tannins, is also recognized as safe by the FDA, although it may lead to caffeine toxicity when combined with caffeine. The amount of ginseng in energy drinks is typically far below the amount used as a dietary supplement, and is generally considered safe. Taurine, an intracellular amino acid, has been reported to have positive inotropic effects; however, this claim is not supported by research. Most energy drinks also contain sugar in an amount that exceeds the maximum recommended daily amount. Young athletes are increasingly using energy drinks because of the ergogenic effects of caffeine and the other ingredients found in these beverages. Energy drinks combined with alcohol are also gaining popularity in young adults, which poses significant concerns about health risks. Other health concerns related to consumption of energy drinks include case reports of seizures and cardiac arrest following energy drink consumption and dental enamel erosion resulting from the acidity of energy drinks.

    2014-01-01

    Millennium Development Goal Target 7c (to halve between 1990 and 2015 the proportion of the global population without sustainable access to safe drinking water), was celebrated as achieved in 2012. However, new studies show that we may be prematurely celebrating. Access to safe drinking water may be overestimated if microbial water quality is considered. The objective of this study was to examine the relationship between microbial drinking water quality and drinking water source in the Puerto Plata region of the Dominican Republic. This study analyzed microbial drinking water quality data from 409 households in 33 communities. Results showed that 47% of improved drinking water sources were of high to very-high risk water quality, and therefore unsafe for drinking. This study provides evidence that the current estimate of safe water access may be overly optimistic, and microbial water quality data are needed to reliably assess the safety of drinking water.

  7. The control of organics in drinking water in Canada and the United States (standards, legislation and practice).

    PubMed

    Toft, P

    1985-12-01

    Both the United States and Canada have a federal form of government, but approaches used in the two countries to ensure the safety of drinking water supplies differ. The Environmental Protection Agency currently enforces regulations for 10 organic chemicals (including 6 pesticides) under the Safe Drinking Water Act and provides advice on others through its health advisory program. Canada, however, does not have similar legislation, but rather provides health-related guidelines for 21 organic chemicals (including 16 pesticides) which are used by the provincial agencies responsible for drinking water supplies. Both countries are in the process of revising their standards and will include a variety of additional synthetic organic chemicals. Where possible, standards are set using a calculated acceptable daily intake usually derived from animal feeding experiments. Procedures for setting standards for carcinogens involve a blend of risk estimation coupled with consideration of the feasibility of reducing the risk in light of socio-economic factors. Most drinking water treatment plans in North America utilize 'conventional' treatment. Some now employ modifications in order to minimize trihalomethane formation. A few use aeration or granular activated carbon to remove synthetic organic chemicals.

    Blette, Veronica

    2008-01-01

    The United States Environmental Protection Agency implements a national drinking-water program under the authority of the Federal Safe Drinking Water Act. Amendments to the Act in 1996 added new provisions to enhance consumer understanding of drinking-water issues. Notification requirements associated with annual consumer confidence reports, source water assessments and state compliance reports are intended to enhance the public's knowledge of the quality of their drinking water. Water utilities are also subject to public notification requirements to provide more timely information to consumers in response to violations of health standards. These right-to-know requirements are intended to build the public's confidence, but communicating with consumers can be challenging for both utility managers and government leaders. This paper discusses the need for timely communication, the challenge of providing information when there is uncertainty in the science and the importance of preparing to respond to critical incidents. Because surveys have shown that other members of the community may have better access to consumers or are more trusted, it is important for water utilities to establish relationships with the media and the local public health community.

  15. Safe motherhood for women refugees.

    PubMed

    O'heir, J

    1999-01-01

    A UN refugee agency supported a review that aims to strengthen safe motherhood services for women refugees in northwest Tanzania. The review, which utilized the safe motherhood needs assessment of WHO as a guide, found that antenatal care as well as labor and delivery services were both available and accessible to women in the refugee camps. However, certain aspects of care could be improved by introducing a shorter schedule of visits. Limiting the use of unqualified care providers was also suggested since this practice increases the risk of disability and death. Furthermore, most of the camps tended to neglect postnatal care, and none of them had written guidelines for care of the mother and newborn. However, draft guidelines were formulated as the review progressed. Up-to-date technical information was also given to staff members to maintain quality care. This review of safe motherhood services demonstrates that it is possible to provide good quality services for children and mothers even in difficult situations. Such services do not require enormous financial resources, neither do they require sophisticated technology and highly specialized staff.

    Authenticating and upgrading system software plays a critical role in information security, yet practical tools for assessing and installing software are lacking in today's marketplace. The SafePatch tool provides the mechanism of performing automated analysis, notification, distribution, and installation of security patches and related software to network-based computer systems in a vendor-independent fashion. SafePatch assists in the authentication of software by comparing the system's objects with the patch's objects. SafePatch will monitor vendor's sites to determine when new patches are released and will upgrade system software on target systems automatically. This paper describes the design of SafePatch, motivations behind the project and the advantages of SafePatch over existing tools.

    2008-01-01

    A targeted review of documented waterborne disease outbreaks over the past decades reveals some recurring themes that should be understood by drinking-water suppliers. Evidence indicates the outbreaks are often linked to some significant change in conditions that provides a sudden challenge to a water system. Severe weather events, such as heavy rainfall or runoff from snow melt, as well as treatment process and system changes, are common risk factors for drinking-water outbreaks. Failure to recognise warning signs and complacency are important contributors to drinking water becoming unsafe. Drinking-water suppliers must focus on competence and vigilance in maintaining effective multiple barriers appropriate to the challenges facing the drinking-water system. Understanding the risk factors and failure modes of waterborne disease outbreaks is an essential component for effective management of community drinking-water supplies and ensuring the delivery of safe drinking-water to consumers.

    2006-04-01

    Seventeen different brands of bottled drinking water, collected from different retail shops in Amritsar, were analyzed for different physical and chemical parameters to ascertain their compliability with the prescribed/recommended limits of the World Heath Organization (WHO) and the United States Environmental Protection Agency (USEPA). It was found that the majority of the brands tested were over-treated. Lower values of hardness, total dissolved solids (TDS) and conductance than the prescribed limits of WHO showed that water was deficient in essential minerals. Minerals like magnesium, potassium, calcium and fluoride were present in some cases in such a low concentration that water seemed to be as good as distilled water. Samples showing fluoride lesser than 0.5 mg/l warranted additional sources of fluoride for the people consuming only bottled water for drinking purposes. Zero values for chlorine demand as shown by all the bottled water samples showed that water samples were safe from micro-organisms. In case of heavy metals, only lead had been found to be greater than the limit of 0.015 mg/l as prescribed by WHO and USEPA, in seven out of 17 samples. Lead even at such a low concentration can pose a great health hazard.

  9. Parenthood, drinking locations and heavy drinking.

    PubMed

    Paradis, Catherine

    2011-04-01

    This study tests the hypothesis that the relationship between parenthood and heavy drinking is mediated by drinking locations. The analysis is based on a random sample of 4180 female and 3630 male Canadian drinkers aged between 18 and 55 years old. A multiple mediator model is tested. Results show that the parental role may be associated with variation in where people drink, and where people drink may be associated with variation in heavy drinking. For women, parenthood is related to a reduction in heavy drinking associated with a reduction of drinking occasions that occur at bars, offset to some extent by the fact that drinking in restaurants is also less common among mothers than non-mothers. For men, parenthood is related to a reduction in heavy drinking partly because fathers more often drink at friends' homes and the proportion of drinking occasions that occur at bars is smaller among fathers than non-fathers. The results of this study correspond with a refined version of the opportunity perspective. Given the nature of the processes by which parenthood is related to heavy drinking, alcohol consumption needs to be understood through a perspective that includes both individual and contextual factors.

    1994-09-01

    Today's regulatory environment has led to the proliferation of voluntary consensus standards and certification programs that are important to ensuring safety and health in a number of areas. One such area -- the treatment and delivery of potable water -- is addressed by the Drinking Water Additives Program.'' At the request of the Environmental Protection Agency (EPA), this program was developed in the mid-1980s by an independent, voluntary consensus standards organization called NSF International (formerly known as the National Sanitation Foundation). This paper explains the need for and the structure of the Drinking Water Additives Program; the rationale for transferring responsibility for its execution from the EPA to the private sector; and the impact of its standards on users, manufacturers, and state and local regulatory bodies. Understanding the additives program is critically important to industry suppliers because, as it continues to gain greater awareness and acceptance, there are a growing number of manufacturers sourcing materials and products primarily from suppliers whose products meet the program's certification requirements.

    NASA Astrophysics Data System (ADS)

    Pranantyo, Ignatius Ryan; Fadmastuti, Mahardika; Chandra, Fredy

    2015-04-01

    Disaster preparedness activities aim to reduce the impact of disasters by being better prepared to respond when a disaster occurs. In order to better anticipate requirements during a disaster, contingency planning activities can be undertaken prior to a disaster based on a realistic disaster scenario. InaSAFE is a tool that can inform this process. InaSAFE is a free and open source software that estimates the impact to people and infrastructure from potential hazard scenarios. By using InaSAFE, disaster managers can develop scenarios of disaster impacts (people and infrastructures affected) to inform their contingency plan and emergency response operation plan. While InaSAFE provides the software framework exposure data and hazard data are needed as inputs to run this software. Then InaSAFE can be used to forecast the impact of the hazard scenario to the exposure data. InaSAFE outputs include estimates of the number of people, buildings and roads are affected, list of minimum needs (rice and clean water), and response checklist. InaSAFE is developed by Indonesia's National Disaster Management Agency (BNPB) and the Australian Government, through the Australia-Indonesia Facility for Disaster Reduction (AIFDR), in partnership with the World Bank - Global Facility for Disaster Reduction and Recovery (GFDRR). This software has been used in many parts of Indonesia, including Padang, Maumere, Jakarta, and Slamet Mountain for emergency response and contingency planning.

    Water pollution with pathogenic microorganisms is one of the serious threats to human health, particularly in developing countries. The main objective of this article is to highlight microbial contamination of drinking water, the major factors responsible for microbial contamination, and the resulting health problems in Pakistan. Furthermore, this study will be helpful for researchers and administrative agencies to initiate relevant studies and develop new policies to protect further deterioration of water supply with pathogenic microbes and ensure clean and safe drinking water to the public in Pakistan. In Pakistan, water at the source, in the distribution network, and at the consumer tap is heavily polluted with coliforms and fecal coliforms all over the country. An overview of more than 7,000 water samples reviewed here reveals that an average of over 71 and 58 % samples in the country was contaminated with total coliforms and fecal coliforms, respectively. Drinking water contamination accounts for 20 to 40 % of all diseases in the country, which causes national income losses of Rs 25-58 billion annually (US$0.25-0.58 billion, approximately 0.6-1.44 % of the country's GDP). Improper disposal of industrial and municipal wastes is the most important factor responsible for water pollution in the country followed by cross-contamination due to old and leaking pipes and lack of water filtration and disinfection facilities. There is an urgent need for emergency steps to stop further deterioration of water quality and improve the existing water quality so as to protect the public from widespread waterborne diseases.

Several regulatory agencies have set or plan to set drinking water guidelines or standards for boron (B). Recent publication of reproductive and developmental toxicity studies by the National Toxicology Program prompted this risk assessment, along with the understanding that boron may be nutritionally essential. A rat developmental toxicity study with a NOAEL of 9.6 mg B/kg/day was selected as the pivotal study on which to base this risk assessment, since it represents the most sensitive endpoint of toxicity. A detailed evaluation of these and other studies allowed modifications of the default values for uncertainty factors to account for the pharmacokinetic similarities among species, the lack of metabolism of inorganic boron-containing compounds, the similarity of the toxicity profile across species, the quality of the toxicological database, and other factors according to the approach described by Renwick previously. Benchmark dose calculations were performed, and the results were in close agreement with the NOAEL selected for this risk assessment. The Reference Dose was calculated to be 0.3 mg B/kg/day, resulting in an acceptable daily intake of 18 mg B/day. Considering that the U.S. average dietary intake of boron is 1.5 mg B/day, 16.5 mg B/day could be available for drinking water or other exposures, if any. A preliminary review of boron data in the National Inorganic Radionuclide Survey by the EPA indicates the median boron level in U.S. drinking water supplies to be 0.031 mg B/liter, and most exposures are less than 2.44 mg B/liter (99th percentile). It is concluded that boron in U.S. drinking water would not be expected to pose any health risk to the public.

    Uranium is a heavy metal that is not only radiologically harmful but also a well-known nephrotoxic element. In this study, occurrence of uranium in drinking water samples from locations near the uranium mining site at Jaduguda, India, was studied by Laser-induced fluorimetry. Uranium concentrations range from 0.03 ± 0.01 to 11.6 ± 1.3 µg l(-l), being well within the US Environmental Protection Agency drinking water limit of 30 μg l(-1). The ingestion dose due to the presence of uranium in drinking water for various age groups varies from 0.03 to 28.3 μSv y(-1). The excess lifetime cancer risk varies from 4.3×10(-8) to 1.7×10(-5) with an average value of 4.8×10(-6), much less than the acceptable excess lifetime cancer risk of 10(-3) for radiological risk. The chemical risk (hazard quotient) has an average value of 0.15 indicating that the water is safe for drinking.

    Drinking groundwater is a significant pathway for human exposure to heavy metals. To evaluate the health effect of some heavy metals ingestion through the groundwater drinking pathway, the authors collected 35 groundwater samples from the drinking water wells of local residents and the exploitation wells of waterworks in Baotou, China. The monitoring results indicate that the groundwater had been polluted by heavy metals in some regions of the study area. A health risk assessment model derived from the U.S. Environmental Protection Agency was used to determine the noncarcinogenic and carcinogenic effects to residents who drink groundwater. All the respondents in the study area were at potential risk of carcinogenic health effects from arsenic when using the lowest safe standard for carcinogenic risk (1E-06). The hazard quotient values for noncarcinogenic health risk of arsenic exceeded 1 in 14.3% of the sampling wells in the study area. The research results could provide baseline data for groundwater utilization and supervision in the Baotou plain area.

    Levels of methyl tertiary-butyl ether (MTBE) in occupational air, ambient air, and drinking water in Nanning, South China, were investigated, and then their potential health risks to occupational workers and the general public were evaluated. Results show that the MTBE concentration in occupational air from 13 service stations was significantly higher than that in ambient air from residential areas (p<0.0001); both are far lower than the threshold limit value-time weighted average of MTBE regulated in the United States (US). The drinking water samples from household taps yielded detectable MTBE in the range of 0.04-0.33 μg/L, which is below the US drinking water standard of 20-40 μg/L. The non-carcinogenic risk of MTBE from air inhalation may be negligible because the calculated hazard quotient was less than 1. The mean MTBE lifetime cancer risk was within the acceptable limit of 1 × 10(-6) to 1 × 10(-4), but the lifetime cancer risk of refueling workers in the urban service station at the 95th percentile slightly exceeded the maximum acceptable carcinogen risk (1 × 10(-4)), indicating the potential carcinogenic health effects on the population highly exposed to MTBE in this region. The hazard index and carcinogenic risk of MTBE in drinking water were significantly lower than the safe limit of US Environmental Protection Agency, suggesting that drinking water unlikely poses significant health risks to the residents in Nanning.

    In 1998, faced with growing international concern, WHO set out an approach for achieving injection safety that encompassed all elements from patients' expectations and doctors' prescribing habits to waste disposal. This article follows that lead and describes the implications of the approach for two injection technologies: sterilizable and disposable. It argues that focusing on any single technology diverts attention from the more fundamental need for health services to develop their own comprehensive strategies for safe injections. National health authorities will only be able to ensure that injections are administered safely if they take an approach that encompasses the whole system, and choose injection technologies that fit their circumstances.

    1995-12-01

    Burner management systems ensure safe admission of fuel to the furnace and prevent explosions. This article describes how programmable control systems can be every bit as safe and reliable as hardwired or standard programmable logic controller-based designs. High-pressure boilers are required by regulatory agencies and insurance companies alike to be equipped with a burner management system (BMS) to ensure safe admission of fuel to the furnace and to prevent explosions. These systems work in parallel with, but independently of, the combustion and feedwater control systems that start up, monitor, and shut down burners and furnaces. Safety and reliability are the fundamental requirements of a BMS. Programmable control system for BMS applications are now available that incorporate high safety and reliability into traditional microprocessor-based designs. With one of these control systems, a qualified systems engineer applying relevant standards, such as the National Fire Protection Assn (NFPA) 85 series, can design and implement a superior BMS.

    In space, the controlled release of certain cargoes is no less useful than the maritime jettisons from which they take their name but is also much more dangerous. Experience has shown that jettisons can be performed safely, but the process is complicated with the path to performing a jettison taking months or even years. In the background, time is also required to write procedures, train the crew, configure the vehicle, and many other activities. This paper outlines the current process used by the National Aeronautics and Space Administration (NASA) for manual jettisons, detailing the methods used to assure that the jettisons and the jettisoned objects are as safe as achievable and that the crew is adequately trained to be able to affect the safe jettison. The goal of this paper is not only to capture what it takes to perform safe jettisons in the near Earth environment but to extrapolate this knowledge to future space exploration scenarios that will likely have Extravehicular Activity (EVA) and International Partner (IP) interfaces.

    The Thai Health Promotion Foundation supported the Improvement of Quality of Life of Informal Workers project in Ban Luang District, Amphur Photaram, Ratchaburi Province. There were many informal workers in Ban Luang District. Sweet-crispy fish producers in Ban Luang were the largest group among the sweet-crispy fish producers in Thailand. This project was aimed at improving living and working conditions of informal workers, with a focus on the sweet-crispy fish group. Good practices of improved living and working conditions were used to help informal workers build safe, healthy and productive work environments. These informal workers often worked in substandard conditions and were exposed to various hazards in the working area. These hazards included risk of exposure to hot work environment, ergonomics-related injuries, chemical hazards, electrical hazards etc. Ergonomics problems were commonly in the sweet-crispy fish group. Unnatural postures such as prolonged sitting were performed dominantly. One hundred and fifty informal workers participated in this project. Occupational health volunteers were selected to encourage occupational health and safety in four groups of informal workers in 2009. The occupational health volunteers trained in 2008 were farmers, beauty salon workers and doll makers. The occupational health and safety knowledge is extended to a new informal worker group: sweet-crispy fish producer, in 2009. The occupational health and safety training for sweet-crispy fish group is conducted by occupational health volunteers. The occupational health volunteers increased their skills and knowledge assist in to make safe home and safe community through participatory oriented training. The improvement of living and working condition is conducted by using a modified WISH, Work Improvement for Safe Home, checklist. The plans of improvement were recorded. The informal workers showed improvement mostly on material handling and storage. The safe uses and safe

    The Safe Drinking Water Act of 1974 represents an important step in improving the quality of public water supply in the United States. However, it fails to address two important problems: (1) The 1970 Public Health Service Community Water Supply Survey revealed that small public water supply systems often deliver poor quality water. The Act does not assure that these supplies will now receive appropriate attention; furthermore, the Act does not address the needs of the 50 million people not now served by public water systems; (2) About one-third of our population draws its drinking waters from polluted sources. The decisions to use these low cost sources were made generations ago when consumers could be protected from water-borne infectious disease. A new problem has now arisen--the presence of numerous synthetic organic chemicals of uncertain health consequence, not removed by conventional water treatment. The Act does not address this problem. Regionalization and the integration of water resource and water pollution control authorities are proposed as a reasonable solution to these problems. The development of dual water supply systems in order to conserve scarce pure water sources for human consumption appears to be a feasible way to avoid using polluted waters for drinking. The development of dual supplies would be enhanced by regionalization and integration of water authorities.

    In this paper, the US Environmental Protection Agency (EPA) presents an approach and a national estimate of drinking water related endemic acute gastrointestinal illness (AGI) that uses information from epidemiologic studies. There have been a limited number of epidemiologic studies that have measured waterborne disease occurrence in the United States. For this analysis, we assume that certain unknown incidence of AGI in each public drinking water system is due to drinking water and that a statistical distribution of the different incidence rates for the population served by each system can be estimated to inform a mean national estimate of AGI illness due to drinking water. Data from public water systems suggest that the incidence rate of AGI due to drinking water may vary by several orders of magnitude. In addition, data from epidemiologic studies show AGI incidence due to drinking water ranging from essentially none (or less than the study detection level) to a rate of 0.26 cases per person-year. Considering these two perspectives collectively, and associated uncertainties, EPA has developed an analytical approach and model for generating a national estimate of annual AGI illness due to drinking water. EPA developed a national estimate of waterborne disease to address, in part, the 1996 Safe Drinking Water Act Amendments. The national estimate uses best available science, but also recognizes gaps in the data to support some of the model assumptions and uncertainties in the estimate. Based on the model presented, EPA estimates a mean incidence of AGI attributable to drinking water of 0.06 cases per year (with a 95% credible interval of 0.02-0.12). The mean estimate represents approximately 8.5% of cases of AGI illness due to all causes among the population served by community water systems. The estimated incidence translates to 16.4 million cases/year among the same population. The estimate illustrates the potential usefulness and challenges of the approach, and

    Expansion of uranium mining in the United States is a concern to some environmental groups and sovereign Native American Nations. An approach which may alleviate some problems is to develop inherently safe in situ uranium recovery ('ISR') technologies. Current ISR technology relies on chemical extraction of trace levels of uranium from aquifers that, once mined, can still contain dissolved uranium and other trace metals that are a health concern. Existing ISR operations are few in number; however, high uranium prices are driving the industry to consider expanding operations nation-wide. Environmental concerns and enforcement of the new 30 ppb uranium drinking water standard may make opening new mining operations more difficult and costly. Here we propose a technological fix: the development of inherently safe in situ recovery (ISISR) methods. The four central features of an ISISR approach are: (1) New 'green' leachants that break down predictably in the subsurface, leaving uranium, and associated trace metals, in an immobile form; (2) Post-leachant uranium/metals-immobilizing washes that provide a backup decontamination process; (3) An optimized well-field design that increases uranium recovery efficiency and minimizes excursions of contaminated water; and (4) A combined hydrologic/geochemical protocol for designing low-cost post-extraction long-term monitoring. ISISR would bring larger amounts of uranium to the surface, leave fewer toxic metals in the aquifer, and cost less to monitor safely - thus providing a 'win-win-win' solution to all stakeholders.

    Drinking water supplies continue to be a major source of human disease and death globally because many of them remain unsafe and vulnerable. Greater efforts are needed to address the key issues and questions which influence the provision of safe drinking water. Efforts are needed to re-evaluate and set new and better priorities for drinking water research and practice. More stakeholders need to be included in the processes of identifying key issues and setting priorities for safe drinking water. The overall approach to drinking water research and the provision of safe drinking water needs to become more rational and scientific, and become more visionary and anticipatory of the ever-present and emerging risks to drinking water safety. Collectively, we need to do a better job of making safe water available, accessible and affordable for all. One such approach to safe water for all is household water treatment and safe storage, which is being promoted globally by the World Health Organization and many other stakeholders and partners to reduce the global burden of waterborne disease.

    Many college students drink heavily and experience myriad associated negative consequences. This review suggests that a developmental perspective can facilitate a better understanding of college drinking. Specifically, using an emerging adulthood framework that considers the ongoing role of parents and neurodevelopmental processes can provide insight into why students drink. Most college students drink and tend to drink more and more heavily than their non–college-attending peers. These drinking patterns are affected by environmental and temporal characteristics specific to the college environment, including residential campus living, the academic week, and the academic year. Additional psychosocial factors are of particular relevance to the drinking behavior of college-age people, and include exaggerated peer norms, the development and use of protective behavioral strategies, and mental health considerations. Understanding the unique interaction of person and environment is key to designing prevention/intervention efforts. PMID:27159817

    The disposal of hydrogen is often required in the operation of an experimental facility that contains hydrogen. Whether the vented hydrogen can be discharged to the atmosphere safely depends upon a number of factors such as the flow rate and atmospheric conditions. Calculations have been made that predict the distance a combustible mixture can extend from the point of release under some specified atmospheric conditions. Also the quantity of hydrogen in the combustible cloud is estimated. These results can be helpful in deciding of the hydrogen can be released directly to the atmosphere, or if it must be intentionally ignited. 15 refs., 5 figs., 2 tabs.

    Legislation passed during this year's legislative session will help the Texas Department of State Health Services (DSHS) identify the source of food-borne illness outbreaks. Senate Bill 81 increases the number of food wholesalers and warehouse operators that must obtain licenses from DSHS. DSHS enforcement activities include follow-up inspections at establishments that have problems, sending warning letters, holding management meetings with the firms, and providing technical assistance. When a food-borne illness outbreak involves a Texas manufacturer, wholesaler, or warehouse, DSHS can recall contaminated products, close establishments temporarily until they can ensure their food is safe or close them permanently, and levy fines.

    Owing to limited surface water during a long-term drought, this work attempted to locate clean and safe groundwater in the Choushui River alluvial fan of Taiwan based on drinking-water quality standards. Because aquifers contained several pollutants, multivariate indicator kriging (MVIK) was adopted to integrate the multiple pollutants in groundwater based on drinking- and raw-water quality standards and to explore spatial uncertainty. According to probabilities estimated by MVIK, safe zones were determined under four treatment conditions--no treatment; ammonium-N and iron removal; manganese and arsenic removal; and ammonium-N, iron, manganese, and arsenic removal. The analyzed results reveal that groundwater in the study area is not appropriate for drinking use without any treatments because of high ammonium-N, iron, manganese, and/or arsenic concentrations. After ammonium-N, iron, manganese, and arsenic removed, about 81.9-94.9% of total areas can extract safe groundwater for drinking. The proximal-fan, central mid-fan, southern mid-fan, and northern regions are the excellent locations to pump safe groundwater for drinking after treatment. Deep aquifers of exceeding 200 m depth have wider regions to obtain excellent groundwater than shallow aquifers do.

    This unmatched case-control study aimed to determine the relationship among caffeine drinks consumption known as "energy drinks consumption", drug dependence and related factors in male construction workers in Chonburi Province. It was conducted during December 15, 2001 and February 15, 2002. Data were collected using interview questionnaires. The logistic regression was used to control possible confounding factors. The subjects consisted of 186 cases who had consumed energy drinks for more than 3 months and 186 controls who had given up for more than 3 months. They were frequency/group matched by age group. There was statistically significant association among energy drinks consumption and overtime work, motivation from advertisements, positive attitude of energy drinks consumption, alcohol drinks, smoking and ex-taking Kratom behavior. Multivariate analyses revealed that only 5 factors were related to energy drinks consumption: marital status (OR = 1.88, 95%CI: 1.14, 3.11), overtime work (OR = 2.84, 95%CI: 1.73, 4.64), motivation from advertisements (OR = 2.72, 95%CI: 1.67, 4.42), positive attitude of energy drinks consumption (OR = 4.06, 95%CI: 1.65, 10.01) and ex-taking Kratom behavior (OR = 2.77, 95%CI: 1.19, 6.44). As a result, construction workers should be provided with the knowledge of energy drinks consumption, the effect of drug dependence behavior, and the advantages of safe and healthy food that is cheap, readily available, and rich in nutrients.

    The consumption of a daily multivitamin among people all over the world is dramatically increasing in recent years. Most of the people believe that if vitamins are not effective, at least they are safe. However, the long term health consequences of vitamins consumption are unknown. This study aimed to assess the side effects and possible harmful and detrimental properties of vitamins and to discuss whether vitamins can be used as safe health products or dietary supplements. We performed a MEDLINE/PubMed, EMBASE, Scopus and Google Scholar search and assessed reference lists of the included studies which were published from 1993 through 2015. The studies, with an emphasis on RCTs (randomized controlled clinical trials), were reviewed. As some vitamins such as fat-soluble vitamins (vitamin A, vitamin D, vitamin E), and also some of the water-soluble vitamins like folic acid may cause adverse events and some like vitamin C is widely taken assuming that it has so many benefits and no harm, we included relevant studies with negative or undesired results regarding the effect of these vitamins on health. Our recommendation is that taking high-dose supplements of vitamins A, E, D, C, and folic acid is not always effective for prevention of disease, and it can even be harmful to the health.

    Drinking-water quality in both urban and rural areas of Pakistan is not being managed properly. Results of various investigations provide evidence that most of the drinking-water supplies are faecally contaminated. At places groundwater quality is deteriorating due to the naturally occurring subsoil contaminants or to anthropogenic activities. The poor bacteriological quality of drinking-water has frequently resulted in high incidence of waterborne diseases while subsoil contaminants have caused other ailments to consumers. This paper presents a detailed review of drinking-water quality in the country and the consequent health impacts. It identifies various factors contributing to poor water quality and proposes key actions required to ensure safe drinking-water supplies to consumers.

    Social Disparities in Drinking Water Quality in California's San Joaquin Valley Carolina Balazs, Rachel Morello-Frosch, Alan Hubbard and Isha Ray Little attention has been given to research on social disparities and environmental justice in access to safe drinking water in the USA. We examine the relationship between nitrate and arsenic concentrations in community water systems (CWS) and the ethnic and socioeconomic characteristics of their customers. We hypothesized that systems in the San Joaquin Valley that serve a higher proportion of minority (especially Latino) residents, and/or lower socioeconomic status (proxied by rates of home ownership) residents, have higher nitrate levels and higher arsenic levels. We used water quality monitoring datasets (1999-2001) to estimate nitrate as well as arsenic levels in CWS, and source location and Census block group data to estimate customer demographics. We found that percent Latino was associated with a .04 mg NO3/L increase in a CWS' estimated nitrate ion concentration (95% CI, -.08, .16) and rate of home ownership was associated with a .16 mg NO3/L decrease (95% CI, -.32, .002). We also found that each percent increase in home ownership rate was associated with a .30 ug As/L decrease in arsenic concentrations (p<.05), but our data showed no significant correlation between arsenic concentration and percent Latino. These results show that exposure disparities and compliance burdens in accordance with EPA standards fell most heavily on socio-economically disadvantaged communities.

    2015-04-01

    Concerns about potential dangers from energy drink consumption by youth have been raised by health experts, whereas energy drink manufacturers claim these products are safe and suitable for marketing to teens. This review summarizes the evidence used to support both sides of the debate. Unlike most beverage categories, sales of energy drinks and other highly caffeinated products continue to grow, and marketing is often targeted to youth under the age of 18 years. These products pose a risk of caffeine toxicity when consumed by some young people, and there is evidence of other troubling physiological and behavioral effects associated with their consumption by youth. The US Food and Drug Administration has indicated it will reexamine the safety of caffeine in the food supply; however, more research is needed to better understand youth consumption of energy drinks and caffeine in general, as well as the long-term effects on health. Meanwhile, policymakers and physician groups have called on energy drink manufacturers to take voluntary action to reduce the potential harm of their products, including placing restrictions on marketing to youth under the age of 18 years. Additional regulatory and legislative options are also being discussed.

    Animal studies and small studies in humans have shown that uranium is nephrotoxic. However, more information about its renal effects in humans following chronic exposure through drinking water is required. We measured uranium concentrations in drinking water and urine in 325 persons who had used drilled wells for drinking water. We measured urine and serum concentrations of calcium, phosphate, glucose, albumin, creatinine, and beta-2-microglobulin to evaluate possible renal effects. The median uranium concentration in drinking water was 28 microg/L (interquartile range 6-135, max. 1,920 microg/L) and in urine 13 ng/mmol creatinine (2-75), resulting in the median daily uranium intake of 39 microg (7-224). Uranium concentration in urine was statistically significantly associated with increased fractional excretion of calcium and phosphate. Increase of uranium in urine by 1 microg/mmol creatinine increased fractional excretion of calcium by 1.5% [95% confidence interval (CI), 0.6-2.3], phosphate by 13% (1.4-25), and glucose excretion by 0.7 micromol/min (-0.4-1.8). Uranium concentrations in drinking water and daily intake of uranium were statistically significantly associated with calcium fractional excretion, but not with phosphate or glucose excretion. Uranium exposure was not associated with creatinine clearance or urinary albumin, which reflect glomerular function. In conclusion, uranium exposure is weakly associated with altered proximal tubulus function without a clear threshold, which suggests that even low uranium concentrations in drinking water can cause nephrotoxic effects. Despite chronic intake of water with high uranium concentration, we observed no effect on glomerular function. The clinical and public health relevance of the findings are not easily established, but our results suggest that the safe concentration of uranium in drinking water may be within the range of the proposed guideline values of 2-30 microg/L.

    The basic elements of a safe birth are proper prenatal care, adequate preparation of the mother, health worker, and site, awareness of the progress of labor and safe delivery, recognition of danger signs, and appropriate follow-up care. Technologies are differentiated by determining 1) the needs of rural birth attendants, 2) the nature of delivery kits, 3) proper cleanliness of the hands and equipment, and appropriate use of 5) disinfecting equipment, 6) drugs and medications, 7) the vertical position, 8) specialized instruments, and 9) records and support materials. Alternatives for measuring time are indicated. Customized kits available from UNICEF are described; some of the problems with these kits are reported. The logistics, referral procedures, and training and supervision needed for appropriate program managements are discussed. Adapting technologies to the local environment requires assessing the practices of traditional birth attendants (TBAs), the provision of kits (cost, ease of use and maintenance, replacement, durability, availability), the training required for proper use of equipment, the logistics of kit use, side effects of technologies, community attitudes, and evaluation. The advantages and disadvantages of including or not including particular supplies in the kit are discussed, i.e., the container for boiling water would either be a local pot or the aluminum carrying case. In lieu of a fingernail brush, a twig may be used for nail cleaning. Hand washing where water shortages exist might entail using a tin with a hole plugged with a stick to let water trickle as needed. Antiseptic solutions such a Dettol or Savlon can be used where a severe shortage exists. Basic equipment includes: soap and water, a container for boiling, other sterile containers, a protective cover of delivery area, towels, swabs, an optional apron, cord ties, a cutting instrument, gauze, a receiving blanket, records, and a carrying case.

    More than 100 million people globally are estimated to be exposed to arsenic in drinking water that exceeds the World Health Organization guideline of 10 µg/L. In an effort to develop and test a low-cost sustainable approach for water arsenic testing in Bangladesh, we conducted a randomized controlled trial which found arsenic educational interventions when combined with fee-based water arsenic testing programs led to nearly all households buying an arsenic test for their drinking water sources (93%) compared with only 53% when fee-based arsenic testing alone was offered. The aim of the present study was to build on the findings of this trial by investigating prospectively the psychological factors that were most strongly associated with switching to arsenic-safe wells in response to these interventions. Our theoretical framework was the RANAS (risk, attitude, norm, ability, and self-regulation) model of behavior change. In the multivariate logistic regression model of 285 baseline unsafe well users, switching to an arsenic-safe water source was significantly associated with increased instrumental attitude (odds ratio [OR] = 9.12; 95% confidence interval [CI] = [1.85, 45.00]), descriptive norm (OR = 34.02; 95% CI = [6.11, 189.45]), coping planning (OR = 11.59; 95% CI = [3.82, 35.19]), and commitment (OR = 10.78; 95% CI = [2.33, 49.99]). In addition, each additional minute from the nearest arsenic-safe drinking water source reduced the odds of switching to an arsenic-safe well by more than 10% (OR = 0.89; 95% CI = [0.87, 0.92]). Future arsenic mitigation programs should target these behavioral determinants of switching to arsenic-safe water sources.

    The International Children's Centre (ICC) works worldwide to improve child health in the least developed countries. In its training and research projects the agency contributes to the Safe Motherhood Initiative to improve the health of mothers and infants. ICC is based in Paris, it was established in 1949, and the agency has cooperated with governments, nongovernmental organizations and international bodies like the World Health Organization (WHO) in child care. ICC's activities reflect concern for the health of women before and during pregnancy and the rest of their lives. The center's work comprises training, research, local projects, and information and documentation. Following the 1987 Nairobi conference on safe motherhood, ICC organized a seminar in Paris on maternal mortality in Sub-Saharan francophone Africa, which led to participation in the Safe Motherhood Initiative with a variety of training and research programs. ICC training is integrated, community-based, and multidisciplinary. Anthropology, psychology, economics and management have played a role in ICC training courses. The center runs an international course on maternal and child health from January to April each year and also organizes distance training courses on problem solving in health care. ICC training programs have taken place in Laos, Senegal, and Vietnam to strengthen the work of maternal and child health training centers there. A 4-week course on economic evaluation of health programs is held in Paris each July. In 1989 and 1990, ICC organized in collaboration with WHO safe motherhood workshops on research methodology in Benin and in Burkina Faso with participants from 6 francophone African countries. One research project in Benin is on risk factors for maternal and perinatal mortality and morbidity, and the other in Cameroon on improving surveillance of pregnancy, delivery, and the postnatal period. ICC focuses on long-term planning and action for the benefit of mothers and children.

    The objective of this study was to investigate how well cows drink the Propeller calcium drink, and it's effect on blood calcium concentration. Drinking was tested in 120 cows right after calving, before cows drank anything else. 60 cows each were offered 20 liters of Propeller calcium drink or 20 liters of water. Cows drank the Propeller as good as water. 72% of all cows drank all 20 liters, 18% drank on average 8.2 liters and 10% drank less than 1 liter. Blood calcium concentration was studied in 16 cows right after calving. Eight cows each were offered 20 liters of Propeller calcium drink or no calcium drink. Blood calcium significantly increased ten minutes after Propeller intake and stayed significantly elevated for 24 hours. Without calcium drink blood calcium levels decreased significantly. Advantages of the new Propeller calcium drink over calcium gels or boli could be that cows now drink calcium themselves and that the Propeller increases blood calcium concentration rapidly and long lasting.

    In the present investigation, radon concentration and heavy metal analysis were carried out in drinking water samples in Jammu district, Jammu & Kashmir, India. The radon concentration was measured by using RAD-7, portable alpha particle detector. The values of radon concentration in drinking water samples were also compared within the safe limit recommended by different health agencies. The total annual effective dose ranged from 53.04 to 197.29 µSv y(-1) The annual effective dose from few locations from the studied area was found to be greater than the safe limit (100 µSv y(-1)) suggested by World Health Organisation (WHO) and EU Council. Heavy metal concentration was determined by atomic absorption spectrophotometer. A total of eight elements were analysed, viz. arsenic, mercury, zinc, iron, copper, chromium, manganese and cadmium. Heavy metals are considered to be the major pollutants of water sources. The results were compared with the limits of WHO, EU and Indian organisations. The trace metal analysis is not on the exceeding side of the permissible limit in all the samples.

    2016-01-01

    Access to safe and reliable drinking water is commonplace for most Canadians. However, the right to safe and reliable drinking water is denied to many First Nations peoples across the country, highlighting a priority public health and environmental justice issue in Canada. This paper describes trends and characteristics of drinking water advisories, used as a proxy for reliable access to safe drinking water, among First Nations communities in the province of Ontario. Visual and statistical tools were used to summarize the advisory data in general, temporal trends, and characteristics of the drinking water systems in which advisories were issued. Overall, 402 advisories were issued during the study period. The number of advisories increased from 25 in 2004 to 75 in 2013. The average advisory duration was 294 days. Most advisories were reported in summer months and equipment malfunction was the most commonly reported reason for issuing an advisory. Nearly half of all advisories occurred in drinking water systems where additional operator training was needed. These findings underscore that the prevalence of drinking water advisories in First Nations communities is a problem that must be addressed. Concerted and multi-faceted efforts are called for to improve the provision of safe and reliable drinking water First Nations communities. PMID:27196919

    Diarrheal illness, frequently associated with fecal-oral transmission, is one of the leading causes of death worldwide. It is commonly preventable through the implementation of safe water practices. This experiment concerns how to best implement safe water practices in a quasi-permanent refugee camp setting with limited ability for structural changes. Specifically, we explore how health promotion activities that help identify target groups for hygiene interventions can play a role in disease prevention. An anonymous survey was conducted at the United Nations Relief and Works Agency Health Clinic in the Kulandia refugee camp to assess the safe water and personal hygiene practices. Demographic and social characteristics, accessible water and personal hygiene characteristics, and gastrointestinal (GI) burden for individuals and their households were assessed. A total of 96 individuals were enrolled; 62 females and 34 males. Approximately 58% of the sample had soap available and washed hands before and after eating and when preparing food. Piped water was the main source of drinking water (62%), while 31% of our sample utilized tanker-trucks. 93% of participants had access to toilet facilities, with 86% of these facilities being private households. 55% practice extra water hygiene measures on their household drinking water source. 51.3% considered vendor cleanliness when they were buying food. 51% had received formal health education. 68.8% had been taught by their parents, but only 55.2% were teaching their children and 15.6% had consistent access to a health professional for hygiene inquiries. Individual variables and hygiene practices associated with lower rates of diarrheal illnesses included having water piped into the home, proper hand washing, adequate soap availability, proper consideration of vendor cleanliness, higher income, levels of education, health hygiene education, and having access to healthcare professions to discuss hygiene related matters.

    2014-01-01

    The paper examines both field experience and research on the prevention of the exponential growth of aflatoxins during multi-month post-harvest storage in hot, humid countries. The approach described is the application of modern safe storage methods using flexible, Ultra Hermetic™ structures that create an unbreatheable atmosphere through insect and microorganism respiration alone, without use of chemicals, fumigants, or pumps. Laboratory and field data are cited and specific examples are given describing the uses of Ultra Hermetic storage to prevent the growth of aflatoxins with their significant public health consequences. Also discussed is the presently limited quantitative information on the relative occurrence of excessive levels of aflatoxin (>20 ppb) before vs. after multi-month storage of such crops as maize, rice, and peanuts when under high humidity, high temperature conditions and, consequently, the need for further research to determine the frequency at which excessive aflatoxin levels are reached in the field vs. after months of post-harvest storage. The significant work being done to reduce aflatoxin levels in the field is mentioned, as well as its probable implications on post-harvest storage. Also described is why, with some crops such as peanuts, using Ultra Hermetic storage may require injection of carbon dioxide, or use of an oxygen absorber as an accelerant. The case of peanuts is discussed and experimental data is described. PMID:24782846

  11. OPINION: Safe exponential manufacturing

    2004-08-01

    In 1959, Richard Feynman pointed out that nanometre-scale machines could be built and operated, and that the precision inherent in molecular construction would make it easy to build multiple identical copies. This raised the possibility of exponential manufacturing, in which production systems could rapidly and cheaply increase their productive capacity, which in turn suggested the possibility of destructive runaway self-replication. Early proposals for artificial nanomachinery focused on small self-replicating machines, discussing their potential productivity and their potential destructiveness if abused. In the light of controversy regarding scenarios based on runaway replication (so-called 'grey goo'), a review of current thinking regarding nanotechnology-based manufacturing is in order. Nanotechnology-based fabrication can be thoroughly non-biological and inherently safe: such systems need have no ability to move about, use natural resources, or undergo incremental mutation. Moreover, self-replication is unnecessary: the development and use of highly productive systems of nanomachinery (nanofactories) need not involve the construction of autonomous self-replicating nanomachines. Accordingly, the construction of anything resembling a dangerous self-replicating nanomachine can and should be prohibited. Although advanced nanotechnologies could (with great difficulty and little incentive) be used to build such devices, other concerns present greater problems. Since weapon systems will be both easier to build and more likely to draw investment, the potential for dangerous systems is best considered in the context of military competition and arms control.

    Studies have linked the consumption of sugary drinks to weight gain, obesity, and type 2 diabetes. Since 2006, New York City has taken several actions to reduce consumption. Nutrition standards limited sugary drinks served by city agencies. Mass media campaigns educated New Yorkers on the added sugars in sugary drinks and their health impact. Policy proposals included an excise tax, a restriction on use of Supplemental Nutrition Assistance Program benefits, and a cap on sugary drink portion sizes in food service establishments. These initiatives were accompanied by a 35% decrease in the number of New York City adults consuming one or more sugary drinks a day and a 27% decrease in public high school students doing so from 2007 to 2013.

    Drinking water for approximately one sixth of US households is obtained from private wells. These wells can become contaminated by pollutant chemicals or pathogenic organisms and cause illness. Although the US Environmental Protection Agency and all states offer guidance for construction, maintenance, and testing of private wells, there is little regulation. With few exceptions, well owners are responsible for their own wells. Children may also drink well water at child care or when traveling. Illness resulting from children's ingestion of contaminated water can be severe. This policy statement provides recommendations for inspection, testing, and remediation for wells providing drinking water for children.

    The current regulatory approach in Germany combines regulations defined in the Drinking Water Ordinance with a comprehensive catalogue of technical rules as well as with guidelines and recommendations by the Federal Environment Agency and the Drinking Water Commission. This approach has proven successful in practice. Some parts would benefit from revision. The regulator is currently contemplating some revision in order to take experience of federal, state and local authorities as well as of water suppliers with implementation of the current Ordinance into account. The intention is improvement particularly towards reducing bureaucracy without compromising the current high level of public health protection through drinking water hygiene in Germany.

  6. Improved but unsustainable: accounting for sachet water in post-2015 goals for global safe water.

    PubMed

    Stoler, Justin

    2012-12-01

    The advent and rapid spread of sachet drinking water in West Africa presents a new challenge for providing sustainable access to global safe water. Sachet water has expanded drinking water access and is often of sufficient quality to serve as an improved water source for Millennium Development Goals (MDG) monitoring purposes, yet sachets are an unsustainable water delivery vehicle due to their overwhelming plastic waste burden. Monitoring of primary drinking water sources in West Africa generally ignores sachet water, despite its growing ubiquity. Sub-Saharan Africa as a region is unlikely to meet the MDG Target for drinking water provision, and post-2015 monitoring activities may depend upon rapid adaptability to local drinking water trends.

    Accounts of drinking water-borne disease outbreaks have always captured the interest of the public, elected and health officials, and the media. During the twentieth century, the drinking water community and public health organizations have endeavored to craft regulations and guidelines on treatment and management practices that reduce risks from drinking water, specifically human pathogens. During this period there also evolved misunderstandings as to potential health risk associated with microorganisms that may be present in drinking waters. These misunderstanding or "myths" have led to confusion among the many stakeholders. The purpose of this article is to provide a scientific- and clinically-based discussion of these "myths" and recommendations for better ensuring the microbial safety of drinking water and valid public health decisions.

  13. Safe roundabouts for cyclists.

    PubMed

    Jensen, Søren Underlien

    2016-09-13

    May roundabouts be safer for cyclists than intersections? How are safe roundabouts designed? This paper tries to answer these questions on the basis of a before-after safety study of conversions of intersections to 255 single-lane roundabouts in Denmark. The before-after study accounts for long-term accident and injury trends and regression-to-the-mean effects. In order to relate safety effects for cyclists of various roundabout design features it is crucial to split the converted sites by speed limit, because safety effects for both cyclists and other road users of converting intersections to roundabouts depend heavily on speed limits on roads entering the converted sites. If speed limits are 70km/h or higher then converting intersections to roundabouts have resulted in bicycle safety improvements in Denmark. Results show that diameter and height of central islands and type of bicycle facilities at single-lane roundabouts have considerable impacts on cyclists' safety. Central island diameters of 20-40m are safer for cyclists than smaller or larger roundabouts. A central island, which middle is elevated 2m or more above the circulating lane, is safer for cyclists than single-lane roundabouts with lower central islands. Single-lane roundabouts with separate cycle paths, where cyclists must yield to motorists entering or exiting the roundabout, are safer than roundabouts with cycle lanes. Single-lane roundabouts are safer for cyclists than intersections regardless of speed limits when these roundabouts have high central islands and/or separate cycle paths.

    2012-05-01

    Negative drinking consequences in college students have been well studied, but emerging evidence points to a role for positive drinking consequences in predicting alcohol related problems. Positive drinking consequences appear to be distinct from other drinking constructs such as drinking expectancies and drinking motives. However, no work has evaluated the role of positive drinking consequences in hazardous drinking college students, a population at high risk for alcohol related problems. The goal of the current study was to examine the effect of positive drinking consequences on problem drinking and alcohol problem recognition in a hazardous drinking college sample. Participants (N=222) were hazardous drinking undergraduate students completing a battery of self-report measures about alcohol use. Findings indicated that positive drinking consequences predicted problem drinking above and beyond other related constructs including positive drinking motives (i.e. enhancement and social). However, positive drinking consequences did not appear to play a significant role in alcohol problem recognition. Future research directions and implications for interventions with hazardous drinking college students are discussed.

  15. GRIK1 Genotype Moderates Topiramate's Effects on Daily Drinking Level, Expectations of Alcohol's Positive Effects, and Desire to Drink

    2014-01-01

    We (Kranzler et al. 2014) reported that topiramate 200 mg/day reduced heavy drinking days and increased abstinent days in 138 heavy drinkers whose treatment goal was to reduce drinking to safe levels. In that 12-week, placebo-controlled study, we measured drinking using the Timeline Follow-back method at each treatment visit. In addition to the intent-to-treat effects of topiramate, we found that a single nucleotide polymorphism (rs2832407) in GRIK1, encoding the GluK1 subunit of the kainate receptor, moderated the treatment effect in European Americans (EAs; n=122). Topiramate reduced heavy drinking only in rs2832407*C allele homozygotes. Here, we augment those analyses by using patients’ daily reports obtained using interactive voice response technology (a) to validate the interactive effects of GRIK1 and topiramate as predictors of drinking level and (b) to examine changes in expected positive effects of drinking (i.e., positive outcome expectancies) and desire to drink. We found that rs2832407*C allele homozygotes treated with topiramate drank less overall during treatment than those receiving placebo, validating our earlier findings for heavy drinking days (Kranzler et al. 2014). There was also a study day × medication group × genotype group interaction that predicted both positive alcohol expectancies and desire to drink, with rs2832407*C-allele homozygotes treated with topiramate showing the largest decreases in these outcomes during the study period. Changes in positive alcohol expectancies or desire to drink did not mediate the effects on drinking. These findings validate and extend our previous pharmacogenetic findings with topiramate.

    The United States Environmental Protection Agency mandates that community water systems (CWSs), or drinking water utilities, provide annual consumer confidence reports (CCRs) reporting on water quality, compliance with regulations, source water, and consumer education. While certain report formats are prescribed, there are no criteria ensuring that consumers understand messages in these reports. To assess clarity of message, trained raters evaluated a national sample of 30 CCRs using the Centers for Disease Control Clear Communication Index (Index) indices: (1) Main Message/Call to Action; (2) Language; (3) Information Design; (4) State of the Science; (5) Behavioral Recommendations; (6) Numbers; and (7) Risk. Communication materials are considered qualifying if they achieve a 90% Index score. Overall mean score across CCRs was 50 ± 14% and none scored 90% or higher. CCRs did not differ significantly by water system size. State of the Science (3 ± 15%) and Behavioral Recommendations (77 ± 36%) indices were the lowest and highest, respectively. Only 63% of CCRs explicitly stated if the water was safe to drink according to federal and state standards and regulations. None of the CCRs had passing Index scores, signaling that CWSs are not effectively communicating with their consumers; thus, the Index can serve as an evaluation tool for CCR effectiveness and a guide to improve water quality communications.

    In response to the Air Force directive to remove Ozone Depleting Chemicals (ODC's) from military specifications and Defense Logistics Agency's Hazardous Waste Minimization Program, we are faced with how to ensure a quality aviation fuel without using such chemicals. Many of these chemicals are found throughout the fuel and fuel related military specifications and are part of test methods that help qualify the properties and quality of the fuels before they are procured. Many years ago there was a directive for military specifications to use commercially standard test methods in order to provide standard testing in private industry and government. As a result the test methods used in military specifications are governed by the American Society of Testing and Materials (ASTM). The Air Force has been very proactive in the removal or replacement of the ODC's and hazardous materials in these test methods. For example, ASTM D3703 (Standard Test Method for Peroxide Number of Aviation Turbine Fuels), requires the use of Freon 113, a known ODC. A new rapid, portable hydroperoxide test for jet fuels similar to ASTM D3703 that does not require the use of ODC's has been developed. This test has proved, in limited testing, to be a viable substitute method for ASTM D3703. The Air Force is currently conducting a round robin to allow the method to be accepted by ASTM and therefore replace the current method. This paper will describe the Air Force's initiatives to remove ODC's and hazardous materials from the fuel and fuel related military specifications that the Air Force Wright Laboratory.

  3. Contaminated drinking water and rural health perspectives in Rajasthan, India: an overview of recent case studies.

    2011-02-01

    Access to safe drinking water is an important issue of health and development at national, regional, and local levels. The concept of safe drinking water assumes greater significance in countries like India where the majority of the population lives in villages with bare infrastructures and poor sanitation facilities. This review presents an overview of drinking water quality in rural habitations of northern Rajasthan, India. Although fluoride is an endemic problem to the groundwater of this region, recently, other anthropogenic chemicals has also been reported in the local groundwater. Recent case studies indicate that about 95% of sites of this region contain a higher fluoride level in groundwater than the maximum permissible limit as decided by the Bureau of Indian Standards. Nitrate (as NO3-) contamination has appeared as another anthropogenic threat to some intensively cultivable rural habitations of this region. Biological contamination has appeared as another issue of unsafe drinking water resources in rural areas of the state. Recent studies have claimed a wide variety of pathogenic bacteria including members of the family Enterobacteriaceae in local drinking water resources. Overall, the quality of drinking water in this area is not up to the safe level, and much work is still required to establish a safe drinking water supply program in this area.

    Multiple regression analysis was used to examine the relationship of five drinking reason factors to drinking locations and consumption variables within a random sample of drinking college students surveyed by telephone. Hypotheses relating self-reported accident involvement after drinking and two specific reason factors - Opposite Sex/Drunkenness and Pleasure - were tested. Both Pleasure and Opposite Sex/Drunkenness were directly related to quantity consumed and to drinking in several away-from-home locations. Opposite Sex/Drunkenness reasons and frequency of drinking in cars significantly contributed to identifying males who reported accident involvement following drinking.

    Uranium concentration in drinking water samples collected from some areas of Northern Rajasthan has been measured using inductively coupled plasma mass spectrometry. The water samples were taken from hand pumps. The uranium concentration in water samples varies from 2.54-133.0 μg L with a mean value of 38.48 μg L. The uranium concentration in most of the drinking water samples exceeds the safe limit (30 μg L) recommended by the World Health Organization. The annual effective dose associated with drinking water due to uranium concentration is estimated from its annual intake using dosimetric information based on ICRP 72. The resulting value of the annual effective dose from drinking water sources is in the range of 2.11-110.45 μSv. The annual effective dose in one of the samples was found to be greater than WHO-recommended level of 100 μSv y.

    2013-03-01

    Between July 1, 2007, and December 31, 2010, Wisconsin health departments tested nearly 4,000 rural drinking water supplies for coliform bacteria, nitrate, fluoride, and 13 metals as part of a state-funded program that provides assistance to low-income families. The authors' review of laboratory findings found that 47% of these wells had an exceedance of one or more health-based water quality standards. Test results for iron and coliform bacteria exceeded safe limits in 21% and 18% of these wells, respectively. In addition, 10% of the water samples from these wells were high in nitrate and 11% had an elevated result for aluminum, arsenic, lead, manganese, or strontium. The high percentage of unsafe test results emphasizes the importance of water quality monitoring to the health of nearly one million families including 300,000 Wisconsin children whose drinking water comes from a privately owned well.

  8. Relationships between drinking problems and drinking locations among convicted drinking drivers.

    2001-08-01

    This study examines relationships between drinking problems and the frequency of drinking in eight types of places within a sample of convicted drinking drivers. Drinking problems were measured by two instruments, the Mortimer-Filkins Questionnaire (MFQ) and the Alcohol Use Disorders Identification Test (AUDIT) Core Questionnaire. Data were collected from convicted drinking drivers who were ordered by the court to attend the Mississippi Alcohol Safety Education Program (MASEP). Both the MFQ and the AUDIT were found to be more strongly related to the frequency of drinking in moving automobiles than to the frequency of drinking in any other type of place. This suggests that drinking drivers with severe drinking problems are more likely to drink in moving automobiles than are those with less severe problems. The strong linkage between severe alcohol problems and drinking in automobiles has important implications with respect to highway safety.

  9. Assessing Drinking Water Quality and Water Safety Management in Sub-Saharan Africa Using Regulated Monitoring Data.

    2016-10-18

    Universal access to safe drinking water is prioritized in the post-2015 Sustainable Development Goals. Collecting reliable and actionable water quality information in low-resource settings, however, is challenging, and little is known about the correspondence between water quality data collected by local monitoring agencies and global frameworks for water safety. Using 42 926 microbial water quality test results from 32 surveillance agencies and water suppliers in seven sub-Saharan African countries, we determined the degree to which water sources were monitored, how water quality varied by source type, and institutional responses to results. Sixty-four percent of the water samples were collected from piped supplies, although the majority of Africans rely on nonpiped sources. Piped supplies had the lowest levels of fecal indicator bacteria (FIB) compared to any other source type: only 4% of samples of water piped to plots and 2% of samples from water piped to public taps/standpipes were positive for FIB (n = 14 948 and n = 12 278, respectively). Among other types of improved sources, samples from harvested rainwater and boreholes were less often positive for FIB (22%, n = 167 and 31%, n = 3329, respectively) than protected springs or protected dug wells (39%, n = 472 and 65%, n = 505). When data from different settings were aggregated, the FIB levels in different source types broadly reflected the source-type water safety framework used by the Joint Monitoring Programme. However, the insufficient testing of nonpiped sources relative to their use indicates important gaps in current assessments. Our results emphasize the importance of local data collection for water safety management and measurement of progress toward universal safe drinking water access.

  10. Emergency do not consume/do not use concentrations for ferric chloride in drinking water.

    PubMed

    Willhite, C C; Ball, G L; Bhat, V S

    2013-03-01

    The U.S. Congress [PL 107-188] amended the Safe Drinking Water Act and required each community water system serving more than 3,000 people to conduct vulnerability assessments. These assessments address potential circumstances that could compromise the safety and reliability of municipal water. Ferric chloride is used in coagulation and flocculation, and it is used to treat raw water with high viral loads, elevated dissolved solids or high bromide. Iron is an essential nutrient, but elevated concentrations of FeCl3 are corrosive as a result of hydrolysis to HCl. Based on a no-observed-adverse effect level (NOAEL) of 0.5% FeCl3 • 6H2O administered in drinking water to male and female F344 rats for up to 2 years, a do not consume concentration of 200 mg FeCl3 /L can be derived. Since instillation of 0.3 M (48.7 g/L) FeCl3 in saline to rodent vagina failed to elicit damage, a topical do not use concentration of 2000 mg FeCl3/L (600 mg Fe/L) can be assigned. The only FeCl3 data available to quantify ocular toxicity involved a pH 1 solution in rabbit eyes, but HCl instillation (pH 2.5) to rabbit eyes found permanent corneal ulceration after 10 min. The pH of FeCl3 in water at the do not use limit (2.4-2.6) is near the pH (2.0) considered corrosive by regulatory agencies. As direct eye contact with water at pH 4.5 or below increases complaints of ocular discomfort, emergency response plans that address FeCl3 in drinking water must account for Fe levels and the pH of the affected water.

    2015-01-01

    Soft drinks consumption is still a controversial issue for public health and public policy. Over the years, numerous studies have been conducted into the possible links between soft drink intake and medical problems, the results of which, however, remain highly contested. Nevertheless, as a result, increasing emphasis is being placed on the health properties of soft drinks, by both the industry and the consumers, for example, in the expanding area of functional drinks. Extensive legislation has been put in place to ensure that soft drinks manufacturers conform to established national and international standards. Consumers trust that the soft drinks they buy are safe and their quality is guaranteed. They also expect to be provided with information that can help them to make informed decisions about the purchase of products and that the information on product labels is not false or misleading. This paper provides a broad overview of available scientific knowledge and cites numerous studies on various aspects of soft drinks and their implications for health safety. Particular attention is given to ingredients, including artificial flavorings, colorings, and preservatives and to the lesser known risks of microbiological and chemical contamination during processing and storage.

  19. UIC permitting process for class IID and Class III wells: Protection of drinking water in New York State

    SciTech Connect

    Hillenbrand, C.J.

    1995-09-01

    The U.S. Environmental Protection Agency (EPA) Region II, Underground Injection Control (UIC) Program regulates injection wells in the State of New York to protect drinking water; UIC regulations can be found under Title 40 of the Code of Federal Regulations Parts 124, 144, 146 and 147. Operators of solution mining injection wells (UIC Class IIIG) and produced fluid disposal wells (UIC Class IID) are required to obtain an UIC permit for authorization to inject. The permitting process requires submittal of drinking water, geologic and proposed operational data in order to assure that pressure build-up within the injection zone will not compromise confining layers and allow vertical migration of fluid into Underground Sources of Drinking Water (USDW). Additional data is required within an Area of Review (AOR), defined as an area determined by the intersection of the adjusted potentiometric surface produced by injection and a depth 50 feet below the base of the lowermost USDW, or a radius of 1/4 mile around the injection well, whichever is greater. Locations of all wells in the AOR must be identified, and completion reports and plugging reports must be submitted. Requirements are set for maximum injection pressure and flow rates, monitoring of brine properties of the injection well and monitoring of water supply wells in the AOR for possible contamination. Any noncompliance with permit requirements constitutes a violation of the Safe Drinking Water Act and is grounds for enforcement action, including possible revocation of permit. Presently four Class IID wells are authorized under permit in New York State. The Queenston sandstone, Medina sandstone, Salina B, Akron dolomite and Oriskany sandstone have been used for brine disposal; the lower Ordovician-Cambrian section is currently being considered as an injection zone. Over one hundred Class IIIG wells are authorized under permit in New York State and all have been utilized for solution mining of the Syracuse salt.

  1. Health and environmental policy issues in Canada: the role of watershed management in sustaining clean drinking water quality at surface sources.

    PubMed

    Davies, John-Mark; Mazumder, Asit

    2003-07-01

    Sustaining clean and safe drinking water sources is increasingly becoming a priority because of global pollution. The means of attaining and maintaining clean drinking water sources requires effective policies that identify, document, and reduce watershed risks. These risks are defined by their potential impact to human health. Health and risk are, therefore, indelibly linked because they are in part defined by each other. Understanding pathogen ecology and identifying watershed sources remains a priority because of the associated acute risks. Surface water quality changes resulting from inputs of human waste, nutrients and chemicals are associated with higher drinking water risks. Nutrient input can increase primary production and the resulting increase of organic matter results in greater disinfection by-product formation or requires greater treatment intensity. Many drinking water disease outbreaks have resulted from breaches in treatment facilities, therefore, even with greater treatment intensity poor source water quality intrinsically has greater associated health risks. Government and international agencies play a critical role in developing policy. The goal of maintaining water supplies whose availability is maximized and risks are minimized (i.e. sustainable) should be a vital part of such policy. Health risks are discussed in the context of a multi-barrier perspective and it is concluded that both passive (protection) and active (prescriptive management) management is necessary for sustainability. Canadian aboriginal water systems, British Columbian water policy and US EPA policies are given as examples. The basis for developing effective policies includes a strong reliance on sound science and effective instrumentation with careful consideration of stakeholders' interests. Only with such directed policies can the future availability of clean drinking water sources be ensured.

    PubMed

    Exner, M; Gornik, V

    2004-07-01

    Nowadays, the parasitic zoonose organisms Giardia lamblia und Cryptosporidium spp. are among the most relevant pathogens of drinking water-associated disease outbreaks. These pathogens are transmitted via a fecal-oral route; in both cases the dose of infection is low. Apart from person-to-person or animal-to-person transmissions, the consumption of contaminated food and water are further modes of transmission. The disease is mainly characterized by gastrointestinal symptoms. In industrialized countries, the prevalence rate of giardiasis is 2-5 % and of cryptosporidiosis 1-3%. Throughout the world, a large number of giardiasis and cryptosporidiosis outbreaks associated with drinking water were published; in 2001 the first case in Germany was identified. Giardia and Cryptosporidium are detected in surface water and sporadically in unprotected groundwater. Use of these waters for drinking water abstraction makes high demands on the technology of the treatment process: because of the disinfectant resistance of the parasites, safe elimination methods are needed, which even at high contamination levels of source water guarantee safe drinking water. Further measures for prevention and control are implementation of the HACCP concept, which includes the whole chain of procedures of drinking water supply from catchment via treatment to tap and a quality management system.

    PubMed

    Heil, M; Haschke, F; Steffan, I; Schuster, E; Schilling, R; Salzer, H P

    1986-02-07

    Daily lead intake from drinking water was estimated on the basis of lead concentrations in running and boiled drinking water samples of 42 Viennese households and reported drinking water consumption of adults living in those households. Lead concentration (means, SD, median) in running water samples (15.3 (37.9) micrograms Pb/l, median 6.3) was significantly higher (p less than 0.005) than in boiled water samples (6.4 (11.1) micrograms Pb/l, median 4.1). The highest lead concentrations in running water samples were found in houses built before 1945. Reported drinking water consumption was 1306 (576) ml/day (median 1242); more than 70% of drinking water was consumed at home. Calculated lead intake from drinking water in Vienna was 11.8 (22) micrograms Pb/day (median 5.2). Lead intake from drinking water was highest (19.5 (31.3) micrograms Pb/day, median 7.3) in houses built before 1945. Lead intake with food was calculated using published data on lead concentrations in food items and on food intake and data from the present study. Calculated average lead intake with food (206 micrograms Pb daily) was far below the estimated safe lead intake proposed by WHO 1972. We conclude that lead intake from drinking water in Vienna is low in most households.

    The Health Advisory Program, sponsored by the Environmental Protection Agency's Office of Water, has issued its report on the element boron: included are the compounds boric acid and borax(sodium tetraborate). It provides information on the health effects, analytical methodology, and treatment technology that would be useful in dealing with the contamination of drinking water. Health Advisories (HAs) describe nonregulatory concentrations of drinking water contaminants at which adverse health effects would not be anticipated to occur over specific exposure durations. HAs serve as informal technical guidance to assist Federal, State, and local officials responsible for protecting public health when emergency spills or contamination situations occur. They are not legally enforceable Federal Standards and are subject to change as new information becomes available.

  1. Nutrition: safe practice in adult enteral tube feeding.

    PubMed

    Fletcher, Jane

    The use of enteral feeding tubes, such as nasogastric and gastrostomy tubes, to support a patient's nutritional intake is generally considered to be safe and effective. However, recent alerts and recommendations from the National Patient Safety Agency (NPSA) regarding enteral feeding have led health professionals to review their practice and guidelines. This article explores safe practice in enteral tube feeding in the light of three NPSA alerts: Promoting safer measurement and administration of liquid medicines via oral and other enteral routes (2007), Early detection of complications after gastrostomy (2010) and Reducing the harm caused by misplaced nasogastric tubes in adults and children (2011).

    We review types of public drinking water and bottled water and provide recommendations on the composition of water for infants. Water used with any of the commercial infant formulas in Spain should contain less than 25 mg/l of sodium. Drinking water must be boiled for a maximum of one minute (at sea level) to avoid excessive salt concentration. Bottled water need not be boiled. Fluoride content in drinking water should be less than 0.3 mg/l in first year of life to prevent dental fluorosis. Nitrate content in water should be less than 25 mg/l to prevent methemoglobinemia. Water with a calcium concentration of between 50 and 100 mg/l is a dietary source of calcium since it provides 24-56 % of the required daily intake in infancy.

  15. [Viruses in drinking water].

    PubMed

    Botzenhart, K

    2007-03-01

    Viruses in drinking water can cause infectious diseases. In the past, hepatitis A and E were the most frequently observed drinking- water-borne viral infections, but in recent years several small- and large-scale norovirus epidemics have been described, even in Europe. All virus species spread via drinking water are of fecal origin. They are regularly identified in waste water even after conventional multi-stage water treatment. The approved disinfection methods can cope with these viruses if they are not integrated in larger particles. For this reason particle separation is particularly important in water treatment. Virological tests are not reliable enough to ensure that drinking water is sufficiently virus-free. The examination of 100 mL of water for E. coli and coliform bacteria is not adequate proof either. If potentially contaminated raw water is used, consumer safety must be ensured by calculating the performance of water treatment plants on a case-by-case basis. Such a calculation takes into account the virus load of the raw water, the efficiency of the physical and chemical particle elimination steps and the effect of disinfection. Those factors which determine the effectiveness of disinfection, namely concentration and exposure time or UV radiation strength, must be adjusted according to the risk of viral infection, and calculated settings must be adhered to, even if favorable E. coli levels may make them seem excessive.

    2012-04-01

    The problems in drinking water management are complex and often solutions must be reached under strict time constrains. This is especially distinct in case of environmental accidents in the catchment areas of the wells that are used for drinking water supply. The beneficial tools that can help decision makers and make program of activities more efficient are decision support systems (DSS). In general they are defined as computer-based support systems that help decision makers utilize data and models to solve unstructured problems. The presented DSS was developed in the frame of INCOME project which is focused on the long-term stable and safe drinking water supply in Ljubljana. The two main water resources Ljubljana polje and Barje alluvial aquifers are characterized by a strong interconnection of surface and groundwater, high vulnerability, high velocities of groundwater flow and pollutant transport. In case of sudden pollution, reactions should be very fast to avoid serious impact to the water supply. In the area high pressures arising from urbanization, industry, traffic, agriculture and old environmental burdens. The aim of the developed DSS is to optimize the activities in cases of emergency water management and to optimize the administrative work regarding the activities that can improve groundwater quality status. The DSS is an interactive computer system that utilizes data base, hydrological modelling, and experts' and stakeholders' knowledge. It consists of three components, tackling the different abovementioned issues in water management. The first one utilizes the work on identification, cleaning up and restoration of illegal dumpsites that are a serious threat to the qualitative status of groundwater. The other two components utilize the predictive capability of the hydrological model and scenario analysis. The user interacts with the system by a graphical interface that guides the user step-by-step to the recommended remedial measures. Consequently, the

    2011-09-01

    Studies that explore social capital and political will [corrected] in the context of safe drinking water provision in [corrected] Canada are limited. This paper presents findings from a study that examines the capacity of rural Canadian communities to attain regulatory compliance for drinking water. Interviews were conducted with water operators and managers in ten rural communities across Atlantic Canada to identify the burden of compliance arising from the implementation of, and adherence to, drinking water regulations. This research identifies the operator as being particularly burdened by regulatory compliance, often resulting in negative consequences including job stress and a strained relationship with the community they serve. Findings indicate that while regulations are vital to ensuring safe drinking water, not all communities have the resources in place to rise to the challenge of compliance. As a result, some communities are being negatively impacted by these regulations, rather than benefit from their intended positive effect.

  19. Carcinogenicity and drinking water.

    PubMed

    Dayan, A D

    1993-01-01

    Water is a powerful solvent that readily dissolves many natural and synthetic substances from the environment (e.g. inorganic salts, humic acids and pesticide residues). The processes of purification, disinfection and preparation and storage necessary to provide and distribute drinking water may introduce further chemicals, including some used for these purposes and others derived by interaction between them and the compounds of natural origin. The composition of drinking water, therefore, is complex and varies between sites and with the seasons. Modern technology is employed to minimise the amounts of many of these substances, but some may persist, including derivatives generated by halogenation and ozonation for disinfection. Some of the substances are genotoxic in the laboratory and a few are proven experimental carcinogens--all at much higher concentrations than those normally found in a drinking water supply. Many ecological and epidemiological surveys have been done to compare the occurrence of various types of tumour in man with exposure to different types of drinking, but no consistent or reliable association has been found. There are serious and probably irremediable methodological weaknesses in these attempts, because of the difficulty of defining the nature of the waters consumed over a major part of life, and the variable composition of waters. The surveys do not permit even a realistic assessment of the upper confidence limit of the exclusion of the risk. Thus, although there is some experimental indication of the possible presence of carcinogenic substances in most or all drinking waters, and of how they are formed, the concentrations are very low and there is no realistic evidence that they have caused harm to man.(ABSTRACT TRUNCATED AT 250 WORDS)

    Energy drinks are widely consumed by adolescents as these claim to improve performance, endurance and alertness. Recent reports have shown that there are no real health benefits of these drinks. On the contrary, certain adverse effects due to energy drinks have come to the forefront, casting a big question-mark on their safety and utility. This review discusses the present status of energy drinks, their active ingredients and their safety. We conclude that energy drinks, despite having some short pleasant effects, can be harmful for the body and are best avoided.

    Boiling is the most common method of household water treatment in developing countries; however, it is not always effectively practised. We conducted a randomized controlled trial among 210 households to assess the effectiveness of water pasteurization and safe-storage interventions in reducing Escherichia coli contamination of household drinking water in a water-boiling population in rural Peru. Households were randomized to receive either a safe-storage container or a safe-storage container plus water pasteurization indicator or to a control group. During a 13-week follow-up period, households that received a safe-storage container and water pasteurization indicator did not have a significantly different prevalence of stored drinking-water contamination relative to the control group [prevalence ratio (PR) 1·18, 95% confidence interval (CI) 0·92-1·52]. Similarly, receipt of a safe-storage container alone had no effect on prevalence of contamination (PR 1·02, 95% CI 0·79-1·31). Although use of water pasteurization indicators and locally available storage containers did not increase the safety of household drinking water in this study, future research could illuminate factors that facilitate the effective use of these interventions to improve water quality and reduce the risk of waterborne disease in populations that boil drinking water.

  9. Source to point of use drinking water changes and knowledge, attitude and practices in Katsina State, Northern Nigeria

    NASA Astrophysics Data System (ADS)

    Onabolu, B.; Jimoh, O. D.; Igboro, S. B.; Sridhar, M. K. C.; Onyilo, G.; Gege, A.; Ilya, R.

    In many Sub-Saharan countries such as Nigeria, inadequate access to safe drinking water is a serious problem with 37% in the region and 58% of rural Nigeria using unimproved sources. The global challenge to measuring household water quality as a determinant of safety is further compounded in Nigeria by the possibility of deterioration from source to point of use. This is associated with the use of decentralised water supply systems in rural areas which are not fully reticulated to the household taps, creating a need for an integrated water quality monitoring system. As an initial step towards establishing the system in the north west and north central zones of Nigeria, The Katsina State Rural Water and Sanitation Agency, responsible for ensuring access to safe water and adequate sanitation to about 6 million people carried out a three pronged study with the support of UNICEF Nigeria. Part 1 was an assessment of the legislative and policy framework, institutional arrangements and capacity for drinking water quality monitoring through desk top reviews and Key Informant Interviews (KII) to ascertain the institutional capacity requirements for developing the water quality monitoring system. Part II was a water quality study in 700 households of 23 communities in four local government areas. The objectives were to assess the safety of drinking water, compare the safety at source and household level and assess the possible contributory role of end users’ Knowledge Attitudes and Practices. These were achieved through water analysis, household water quality tracking, KII and questionnaires. Part III was the production of a visual documentary as an advocacy tool to increase awareness of the policy makers of the linkages between source management, treatment and end user water quality. The results indicate that except for pH, conductivity and manganese, the improved water sources were safe at source. However there was a deterioration in water quality between source and

  11. Development of a drinking water regulation for perchlorate in California.

    PubMed

    Tikkanen, Maria W

    2006-05-10

    Perchlorate is an environmental contaminant often associated with military installations and rocket propellant manufacture and testing facilities across the U.S. Highly water soluble, perchlorate has been found by federal and state agencies at almost 400 sites within the U.S. in groundwater, surface water, soil or public drinking water. There is no federal drinking water standard for perchlorate, but it is on the drinking water Contaminant Candidate List, and falls under the Unregulated Contaminant Monitoring Rule (UCMR) for which monitoring is required. The recent National Academy of Science (NAS) report on the potential health effects of perchlorate recommended a perchlorate reference dose of 0.0007 mg/kg of body weight which would be equivalent to a drinking water concentration of 24.5 microg/L. In California, approximately 395 wells in 96 water systems have been shown to contain perchlorate, and about 90% of these are located in Southern California. Water taken from the Colorado River, a major surface water supply to Southern California, has had reported detections of perchlorate ranging from non-detect to 9 microg/L. California has established a Public Health Goal (PHG) of 6 microg/L for perchlorate, and a proposed drinking water regulation is imminent. This review details the regulatory process involved with particular attention given to the occurrence of perchlorate in California drinking water sources and analytical methodology utilized.

    PubMed

    Onyango-Ouma, W; Gerba, Charles P

    2011-12-01

    A cross-sectional descriptive study was conducted to examine away-from-home drinking water consumption practices and the microbiological quality of water consumed in rural western Kenya. The study involved adults and schoolchildren. Data were collected using focus group discussions, questionnaire survey, observations, diaries and interviews. The findings suggest that away-from-home drinking water consumption is a common practice in the study area; however, the microbiological quality of the water consumed is poor. While some respondents perceive the water to be safe for drinking mainly because of the clear colour of the water, others are forced by circumstances to drink the water as it is owing to a lack of alternative safe sources. It is concluded that there is a need for new innovative approaches to address away-from-home drinking water consumption in resource-poor settings in order to complement and maximize the benefits of point-of-use water treatment at the household level.

  13. Soft drinks and 'desire to drink' in preschoolers.

    PubMed

    Sweetman, Claire; Wardle, Jane; Cooke, Lucy

    2008-12-02

    Interest in soft drink consumption has increased following a dramatic rise in intake over recent years. Research to date has focused primarily on general trends in consumption or on understanding the mechanism by which soft drink consumption may be linked to weight gain. It is clear however that there is considerable individual variability in the extent to which soft drinks are consumed and factors potentially influencing intake have received little attention. This study examines how the Child Eating Behaviour Questionnaire (CEBQ) construct 'Desire to Drink' (DD) relates to drink consumption, preferences and BMI-SDS.Three hundred and forty six same-sex twin children (mean age 11.2 years; s.d. 0.54; 56% female; 53% dizygotic) were weighed, measured and reported their liking for milk, water, fruit juice, fruit squash and sweetened soft drinks. Mothers reported on their child's drink consumption and completed the CEBQ.Scores on the CEBQ DD subscale were not significantly related to child BMI-SDS in this sample. Children scoring higher on DD had higher preferences for sugar-sweetened soft drinks (p = 0.016), fruit squash (p = 0.042) and milk (p = 0.020) than children scoring lower on the scale. DD was also positively related to more frequent consumption of sugar-sweetened soft drinks (p = 0.017) and low calorie soft drinks (p = 0.003). No relationship was observed between DD scores and liking for or intake of water or 100% fruit juice.These findings suggest that the construct desire to drink in children is related to a liking for consuming sweetened drinks, and does not appear to simply denote greater thirst or hunger. This may have important implications for the ongoing development of dietary patterns and weight status in the longer term through an increased preference for sweet things in the mouth and a failure to compensate for calories provided by drinks.

  18. How dogs drink water

    Animals with incomplete cheeks (i.e. dogs and cats) need to move fluid against gravity into the body by means other than suction. They do this by lapping fluid with their tongue. When a dog drinks, it curls its tongue posteriorly while plunging it into the fluid and then quickly withdraws its tongue back into the mouth. During this fast retraction fluid sticks to the ventral part of the curled tongue and is drawn into the mouth due to inertia. We show several variations of this drinking behavior among many dog breeds, specifically, the relationship between tongue dynamics and geometry, lapping frequency, and dog weight. We also compare the results with the physical experiment of a rounded rod impact onto a fluid surface. Supported by NSF PoLS #1205642.

  19. [Assessment of so called organic trace compounds in drinking water from the regulatory, health and aesthetic-quality points of view, with special consideration given to pharmaceuticals].

    PubMed

    Dieter, H H; Mückter, H

    2007-03-01

    More than 2500 chemically defined substances are approved as drugs in Germany. Unlike agricultural pesticides, these biologically active structures are not used in open environmental compartments and therefore their environmental toxicological data base is not nearly as complete. Nevertheless, some of them become environmental contaminants after their intended use. Therefore, from the viewpoint of environmental health protection, there are gaps in their health-related environmental risk assessment. Organic trace compounds that lack an adequate toxicological database, and their mixtures, in drinking water can be safely regulated and provisionally assessed by combining the "similar joint action" addition rule with the recommendation of the Federal Environment Agency of March 2003 "Assessing the presence of substances in drinking water without (adequate) toxicological database from the health point of view". The general precautionary value (Gesundheitlicher Orientierungswert GOW1=0.10 microg/l), which is a recommendation for weakly to not genotoxic compounds, re presents a workable compromise between preventive health protection, water management considerations and aesthetic quality claims (purity). Compliance with this value in the long term will only be possible if the chemical and biological degradation of pharmaceuticals and their metabolites in waste water and waste water treatment plants is effectively improved. Alternatively, there is the risk of drinking water degenerating into a sink for highly mobile, polar and persistent compounds. Their elimination at a stage as late as technical drinking water treatment would be neither close to the initial cause nor justifiable in terms of technical effectiveness. The risk assessment of their byproducts would give rise to further uncertainties. Possible conflicts with the therapeutic quality must be solved by developing substitute products which are environmentally sound.

    Disclosed is a locking device for eliminating external control of a secured space formed by fixed and movable barriers. The locking device uses externally and internally controlled locksets and a movable strike, operable from the secured side of the movable barrier, to selectively engage either lockset. A disengagement device, for preventing forces from being applied to the lock bolts is also disclosed. In this manner, a secured space can be controlled from the secured side as a safe-haven. 4 figures.

    The transfusion process has many stages, each involving different members of staff in different locations. This gives rise to a significant potential for errors. Nurses are involved in many of these stages and therefore require knowledge, skills and competence in the process to ensure the safety of patients. This third article in our five-part series on blood transfusion discusses the safe administration of blood components and the key principles to which nurses must adhere.

    2007-10-01

    We assessed fecal contamination of drinking water in households in 2 peri-urban communities of Lima, Peru. We measured Escherichia coli counts in municipal source water and, within households, water from principal storage containers, stored boiled drinking water, and water in a serving cup. Source water was microbiologically clean, but 26 (28%) of 93 samples of water stored for cooking had fecal contamination. Twenty-seven (30%) of 91 stored boiled drinking water samples grew E. coli. Boiled water was more frequently contaminated when served in a drinking cup than when stored (P < 0.01). Post-source contamination increased successively through the steps of usage from source water to the point of consumption. Boiling failed to ensure safe drinking water at the point of consumption because of easily contaminated containers and poor domestic hygiene. Hygiene education, better point-of-use treatment and storage options, and in-house water connections are urgently needed.

    Historical trends in alcohol use among U.S. adolescents, as well as data regarding alcohol-related traffic fatalities among youth, indicate decreases in alcohol use. Nevertheless, alcohol use patterns still indicate high rates of binge drinking and drunkenness and the co-occurrence of alcohol use among youth with risky sexual activity, illicit substance use, and poor school performance. This article discusses unique elements of alcohol use among adolescents relative to adults that pose risks for alcohol misuse and alcohol-related problems. These differences range from patterns of drinking to differential sensitivity to alcohol. Developmental differences between adolescents and adults also are discussed with regard to age-normative developmental tasks and distinctions in brain development that may affect differences in drinking patterns. Epidemiologic findings on sexual-minority youth are provided, as are global trends in alcohol use among early adolescents and youth. It is proposed that using information about differences between youth and adults will be helpful in directing future etiologic and intervention research by capitalizing on unique biological, psychological, and social factors that may affect the success of efforts to reduce alcohol use among early adolescents and youth.

    National and sub-national governments develop and enforce regulations to ensure the delivery of safe drinking water in the United States (US) and countries worldwide. However, periodic contamination events, waterborne endemic illness and outbreaks of waterborne disease still occur, illustrating that delivery of safe drinking water is not guaranteed. In this study, we examined the potential added value of a preventive risk management approach, specifically, water safety plans (WSPs), in the US in order to improve drinking water quality. We undertook a comparative analysis between US drinking water regulations and WSP steps to analyze the similarities and differences between them, and identify how WSPs might complement drinking water regulations in the US. Findings show that US drinking water regulations and WSP steps were aligned in the areas of describing the water supply system and defining monitoring and controls. However, gaps exist between US drinking water regulations and WSPs in the areas of team procedures and training, internal risk assessment and prioritization, and management procedures and plans. The study contributes to understanding both required and voluntary drinking water management practices in the US and how implementing water safety plans could benefit water systems to improve drinking water quality and human health.

    Following more than a decade of scientific debate about the setting of a standard for 222Rn in drinking water, Congress established a timetable for the promulgation of a standard in the 1996 Amendments to the Safe Drinking Water Act. As a result of those Amendments, the EPA contracted with the National Academy of Sciences to undertake a risk assessment for exposure to radon in drinking water. In addition, the resulting committee was asked to address several other scientific issues including the national average ambient 222Rn concentration and the increment of 222Rn to the indoor- air concentration arising from the use of drinking water in a home. A new dosimetric analysis of the cancer risk to the stomach from ingestion was performed. The recently reported risk estimates developed by the BEIR VI Committee for inhalation of radon decay products were adopted. Because the 1996 Amendments permit states to develop programs in which mitigation of air- producing health-risk reductions equivalent to that which would be achieved by treating the drinking water, the scientific issues involved in such 'multimedia mitigation programs' were explored.

    Introduction Access to safe drinking-water is one of the most important public health concerns in an emergency setting. This descriptive study reports on an assessment of water quality in drinking-water supply systems in areas affected by Typhoon Haiyan immediately following and 10 months after the typhoon. Methods Water quality testing and risk assessments of the drinking-water systems were conducted three weeks and 10 months post-Haiyan. Portable test kits were used to determine the presence of Escherichia coli and the level of residual chlorine in water samples. The level of risk was fed back to the water operators for their action. Results Of the 121 water samples collected three weeks post-Haiyan, 44% were contaminated, while 65% (244/373) of samples were found positive for E. coli 10 months post-Haiyan. For the three components of drinking-water systems – source, storage and distribution – the proportions of contaminated systems were 70%, 67% and 57%, respectively, 10 months after Haiyan. Discussion Vulnerability to faecal contamination was attributed to weak water safety programmes in the drinking-water supply systems. Poor water quality can be prevented or reduced by developing and implementing a water safety plan for the systems. This, in turn, will help prevent waterborne disease outbreaks caused by contaminated water post-disaster. PMID:26767136

  10. Emergency do not consume/do not use concentrations for blended phosphates in drinking water.

    PubMed

    Willhite, C C; Ball, G L; Bhat, V S

    2013-03-01

    The U.S. Congress [PL 107-188] amended the Safe Drinking Water Act and required each community water system serving more than 3,000 people to conduct vulnerability assessments. These assessments address potential circumstances that could compromise the safety and reliability of municipal water. The present evaluation concerns the concentrations of the blended phosphates (also known as polyphosphates, condensed complex phosphates, polyphosphate glassy balls, and pyrophosphates) intended to aid regulatory agencies in decisions to avoid contact with affected water. Polyphosphates are direct food additives and they are used to treat municipal drinking water, but depending upon the concentration and duration of exposure these substances can induce chemical burns. Ingested polyphosphates are degraded by phosphatase enzymes to monophosphates, substances that are over-the-counter bowel purgatives. High oral doses of the monophosphates can induce transient hyperphosphatemia in older and susceptible young people, which can lead to acute phosphate nephropathy. In some patients, the condition is fatal. Based on the acute diarrhea after the ingestion of a single oral dose of monobasic (NaH2PO(4)) and dibasic (Na2HPO(4)) monophosphates in adults, a do not consume concentration of 600 mg PO(4)/L can be derived. Based on mild local irritation after topical application of 1.0% sodium metaphosphate [(NaPO(3))6 • H2O] to intact skin of sensitive volunteers, a do not use concentration of 8,000 mg PO4/L can be assigned. Given the lack of eye irritation in rabbits after direct instillation of 0.2% (NaPO(3))6 • H2O, an acute ocular contact limit of 50 mg PO4/L serves as the overall do not use level.

    Obesity prevalence is increasing all over the world. Most affected are people changing from a traditional lifestyle to an environment with both availability of high energy diet and less physical activity. Glycemic index (GI) is a measure of dietary glycemic carbohydrates, representing their ability to raise blood glucose concentrations. It refers to the postprandial blood glucose response expressed as a percentage of the response to a reference food (glucose or white bread) containing the same carbohydrate content. Given the present high consumption of sugary drinks, the putative contribution of these products to obesity deserves investigation. The aim of this study was to determine the GI of some drinks from the Portuguese market. Postprandial glycemia after ingestion of apple Frutis, peach Frutis, Green tea Frutea, green tea, black tea, lupin infusion, rooibos infusion, raftilose solution or bran solution has been determined for two hours in a caucasian population of young adults of any sex, 17 to 24 years of age. Apple Frutis GI was found to be 54.3, i.e., a low GI; Frutea Green tea had a GI of 64.7, considered as a moderate GI; peach Frutis showed a high GI, 86.6. Green and Black teas as well as rooibos and lupin infusions, all with added glucose (25 g), did not change glycemic response in comparison with the reference solution (water with 25 g glucose). No differences were seen after raftilose and bran solutions by comparison with the reference solution. GI information may help the choice of carbohydrates to include in a healthy diet. Formerly considered as a parameter of interest to diabetic patients, it may actually interest anybody concerned with a healthy diet. This study has been performed by medical and nutritional science students, who observed glycemic excursions in themselves, after drink ingestion. This experiment allowed them to see the impressive rise of glycemia after ingestion of a sugary drink, by comparison with basal levels which would not

  12. Aesthetic issues for drinking water.

    2006-01-01

    Although many people expect their drinking water to be "flavorless", natural and processed drinking waters have flavors due to minerals and organics in the natural water, inputs from any step of water processing or transport, and interaction of these chemicals with an individuals' nose and mouth. Since people can detect the flavor of water, the idea has been proposed that drinking water consumers be considered as sentinels who monitor water quality. This paper explores specific sensory components of drinking water, how humans perceive their drinking water, and future directions for aesthetic research that can better explain causes of and treatments for tastes and odors in drinking water and the human factors that make water a desirable beverage.

    Drinking water for approximately one sixth of US households is obtained from private wells. These wells can become contaminated by pollutant chemicals or pathogenic organisms, leading to significant illness. Although the US Environmental Protection Agency and all states offer guidance for construction, maintenance, and testing of private wells, there is little regulation, and with few exceptions, well owners are responsible for their own wells. Children may also drink well water at child care or when traveling. Illness resulting from children's ingestion of contaminated water can be severe. This report reviews relevant aspects of groundwater and wells; describes the common chemical and microbiologic contaminants; gives an algorithm with recommendations for inspection, testing, and remediation for wells providing drinking water for children; reviews the definitions and uses of various bottled waters; provides current estimates of costs for well testing; and provides federal, national, state, and, where appropriate, tribal contacts for more information.

    Sports drinks were originally developed to improve hydration and performance in athletes taking part in intense or endurance sporting events. These drinks contain relatively high amounts of carbohydrates (sugars), salt, and citric acid. These ingredients create the potential for dental ramifications and overall public health consequences such as obesity and diabetes. High intake of sports drinks during exercise, coupled with xerostomia from dehydration, may lead to the possibility of erosive damage to teeth.

    The societal changes in India and the available variety of reproductive health services call for evidence to inform health systems how to satisfy young women’s reproductive health needs. Inspired by Foucault’s power idiom and Bandura’s agency framework, we explore young women’s opportunities to practice reproductive agency in the context of collective social expectations. We carried out in-depth interviews with 19 young women in rural Rajasthan. Our findings highlight how changes in notions of agency across generations enable young women’s reproductive intentions and desires, and call for effective means of reproductive control. However, the taboo around sex without the intention to reproduce made contraceptive use unfeasible. Instead, abortions were the preferred method for reproductive control. In conclusion, safe abortion is key, along with the need to address the taboo around sex to enable use of “modern” contraception. This approach could prevent unintended pregnancies and expand young women’s agency. PMID:26531879

    Although increasingly global, data-driven genomics and other ‘omics’-focused research hold great promise for health discoveries, current research ethics review systems around the world challenge potential improvements in human health from such research. To overcome this challenge, we propose a ‘Safe Harbor Framework for International Ethics Equivalency’ that facilitates the harmonization of ethics review of specific types of data-driven international research projects while respecting globally transposable research ethics norms and principles. The Safe Harbor would consist in part of an agency supporting an International Federation for Ethics Review (IFER), formed by a voluntary compact among countries, granting agencies, philanthropies, institutions, and healthcare, patient advocacy, and research organizations. IFER would be both a central ethics review body, and also a forum for review and follow-up of policies concerning ethics norms for international research projects. It would be built on five principle elements: (1) registration, (2) compliance review, (3) recognition, (4) monitoring and enforcement, and (5) public participation. The Safe Harbor would create many benefits for researchers, countries, and the general public, and may eventually have application beyond (gen)omics to other areas of biomedical research that increasingly engage in secondary use of data and present only negligible risks.
