    Calabrese, E.J.; Gilbert, C.E.; Pastides, H.

    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.

    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.

    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. Case studies presented highlight how the RMPs are assisting drinking water providers to identify incidents of potential health concern and implement corrective actions.

    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 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.

    Organic and microbial contaminants that are currently or are planned to be regulated under the 1986 amendments to the Safe Drinking Water Act (SDWA) were investigated in the following water supplies of the Urban Water Consortium established by The Water Resources Research Institute of The University of North Carolina: Burlington, Orange Water and Sewer Authority (OWASA), Durham, High Point, Raleigh and Winston-Salem. A review of the NPDES permits in each of these water supply sources confirmed that only the water supplies for Raleigh and Winston-Salem are vulnerable to industrial waste from direct discharges (six and seven sources, respectively). Those listed for Raleigh, however, are classified as minor industrial dischargers by an EPA rating system. At High Point, vulnerability is not so much from industrial discharges as from the potential for accidental contamination due to leakage from several oil storage depots. Very few contaminants that are or will be regulated by the SDWA were uncovered in these NPDES permits. It appears that the SDWA amendments' requirement for removal of disinfection by-products will have a much greater impact on the six cities studied than will the regulations regarding SOCs and VOCs.

    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.

    As a result of the U.S. Congress passing the 1986 Amendments to the Safe Drinking Water Act, the number of regulated contaminants that must be monitored in public water systems has increased from 24 to 85. The economic impact of the new legislation is greater on small systems than large systems because of economies of scale. In addition, more highly trained water treatment plant operators will be needed to deal with the complex legislation and to ensure the continuous supply of safe drinking water to their communities. Because of the complexity and increased scope of the 1986 Amendments to the Safe Drinking Water Act, a detailed discussion of the requirements that must be met by each public water supply is presented as background information. The objectives of the research were to: (1) determine the economic impacts of the 1986 Amendments on water systems throughout the State of Mississippi, (2) determine the number of systems that will need new and/or upgraded treatments technology to comply with the regulations, and (3) provide an assessment of the needs of the State DWS.

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

    SciTech Connect

    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.

  16. Overview of the regulation of hazardous chemicals: SDWA (Safe Drinking Water Act), RCRA (Resource Conservation and Recovery Act), and CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act)

    SciTech Connect

    Baes, C.F. III

    1989-01-01

    The regulation of nonradioactive hazardous chemicals is carried out under a number of federal environmental laws that regulate either hazardous products, substances, or wastes. Because each law is intended to provide protection from different classes of substances (e.g., wastes vs products) or protect different media (e.g., air, water, land), the standards and levels of protection for different hazardous chemicals may be different. Nevertheless, one agency -- the Environmental Protection Agency (EPA) -- has primary responsibility for both promulgating regulations mandated by Congress under the various statutes and enforcement of the regulations. One overriding principal underlies the maze of complex regulations that govern the transport, treatment, storage, and disposal of hazardous substances: protect human health and the environment. It is beyond the scope of this talk to comprehensively examine all of the regulations and standards that govern the management of hazardous chemicals. Instead this discussion will focus on three statutes, the Safe Drinking Water Act (SDWA), the Resource Conservation and Recovery Act (RCRA), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), that together provide a basis for a basic understanding of the approach that the EPA takes to regulating hazardous chemicals.

    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.

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.

    The 1986 Amendments to the Safe Drinking Water Act (SDWA) require EPA to develop regulations for 83 specific contaminants as well as regulations specifying filtration and disinfection treatment requirements. All of the regulations will be promulgated by the early 1990's. Under Executive order 12291, EPA is required to perform a Regulatory Impact Analysis of all proposed regulations. The results of the individual analyses of each major rule package have been summed to provide a perspective on the cumulative cost impacts of the entire SDWA program. In addition, projections of where actual cost impacts will be incurred have been developed for each rule package, permitting an aggregate projection of SDWA compliance expenditures through the year 2010. The EPA intends to update the analysis on an annual basis to incorporate revised impact results for regulations that had not been promulgated at the time the interim final report was completed.

    The production of adequate and safe drinking water is a high priority issue for safeguarding the health and well-being of humans all over the world. Traditionally, microbiological quality of drinking water has been the main concern, but over the last decades the attention of the general public and health officials on the importance of chemical quality and the threat of chemical pollutants have increased with the increase of our knowledge on the hazards of chemical substances. There are many sources of contamination of drinking water. Broadly they can be divided into two categories: contaminants originating from surface and groundwater, and contaminants used or formed during the treatment and distribution of drinking water. Contaminants in surface and groundwater can range from natural substances such as arsenic and manganese leaching from soil, to contaminants introduced by human activities, such as run-off from agricultural activities, controlled discharge from sewage treatment works and industrial plants, and uncontrolled discharges or leakage from landfill sites and from chemical accidents. Disinfectants and disinfectant by-products are well known contaminants resulting from the processes used by the drinking water industry for the treatment and distribution of water. The basic question in the production of drinking water is how to rid drinking water of potentially dangerous microorganisms and chemicals without introducing new hazards that might pose new and different threats to human health. It is the responsibility of toxicologists to provide risk assessments for chemical pollutants and to derive guidelines or standards for drinking water quality below which no significant health risk is encountered, to assure consumers that drinking water is safe and can be consumed without any risk. This paper will focus on the toxicological procedures used by the World Health Organization to derive guideline values for chemical compounds in drinking water, and will touch

    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.

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.

This chapter summarizes the need for safe drinking water, the scale of the global problem, and various methods tried to address it. Then it gives the history and current status of an innovation ("UV Waterworks™") developed to address this major public health challenge. It reviews water disinfection technologies applicable to achieve the desired quality of drinking water in developing countries, and specifically, the limitations overcome by one particular invention: UV Waterworks. It then briefly describes the business model and financing option than is accelerating its implementation for affordable access to safe drinking water to the unserved populations in these countries. Thus this chapter describes not only the innovation in design of a UV water disinfection system, but also innovation in the delivery model for safe drinking water, with potential for long term growth and sustainability.

    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.

    To assist the Office of Drinking Water in estimating the state costs of regulatory options and in providing guidance and assistance to state programs, the Survey of State Primacy Program Resource Needs was conducted in the summer and fall of 1988. The survey was a joint effort between EPA and the Association of State Drinking Water Administrators (ASDWA). A detailed 18 page questionnaire and a 38 page supplement were prepared to obtain from each state and territory an estimate of the staff and funding resources needed both to implement existing programs and to meet the new requirements. ASDWA distributed the survey to all states and territories and compiled the responses in a data base as they were received. EPA supported ASDWA in delineating the expected requirements, providing implementation schedules of the forthcoming rules, and analyzing the results of the survey. The report discusses the methodology used in developing and conducting the survey and presents the results of the analyses.

    At present, 70 countries worldwide are affected by groundwater contamination by arsenic (As) released from predominantly geogenic sources. Consequently, the As problem is becoming a global issue. The option to target As-safe aquifers, which uses geological, geochemical, hydrogeological, morphological and climatic similarities to delimit As-safe aquifers, appears as a sustainable mitigation option. Two pilot areas, Meghna Flood Plain in Matlab Upazila, representative of Bengal Delta in Bangladesh, and Río Dulce Alluvial Cone, representing a typical aquifer setting in the Chaco-Pampean Plain in Argentina groundwater As occurrence, were compared. In rural Bangladesh, As removal techniques have been provided to the population, but with low social acceptance. In contrast, "targeting As-safe aquifers" was socially accepted in Bangladesh, where sediment color could be used to identify As-safe aquifer zones and to install safe wells. The investigation in Argentina is more complex because of very different conditions and sources of As. Targeting As-safe aquifers could be a sustainable option for many rural areas and isolated peri-urban areas.

    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.

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

    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

    Studies were conducted to assess the physical, chemical, and bacteriological qualities of drinking water in Mbandjock, Cameroon. Study results indicated that the vast majority of drinking water sources possessed acceptable physical and chemical qualities, according to the World Health Organization standards. However, microbiological analyses revealed that only the waters treated by the Cameroon National Water Company (SNEC) and the Sugar Processing Company (SOSUCAM) were acceptable for human consumption. All spring and well waters presented evidences of fecal contamination from human and/or animal origin. Water from these sources should, therefore, be treated before use for drinking. Since the majority of the population gets its water from wells and springs, there is an urgent need to develop a health education program, within the framework of primary health care, with respect to environmental sanitation and safe drinking water supply in this community.

    Non-carbonated, low-calorie soft drink concentrates (cordials), when diluted according to manufacturers' instructions, had significant antibacterial effects in vitro. Bacteria affected include Vibrio cholerae, Aeromonas hydrophila, Shigella sonnei, Salmonella typhimurium and Escherichia coli. With vibrios, bacterial counts were reduced from 10(6)/ml to undetectable numbers in less than 10 min. Escherichia coli in an initial concentration of 10(6)/ml became undetectable after incubation for 1 h with one brand of cordial. Naturally contaminated water can be rendered potable by incubation with cordials at room temperature for 1 h. This may be a way to reduce the risk of water-borne diarrhoea, particularly where the cleanliness of drinking waters cannot be otherwise assured, for example when making up oral rehydration fluids and for travellers in high-risk areas.

    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.

    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.

    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

    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

    Securing safe and adequate drinking water is an ongoing issue for many Canadian First Nations communities despite nearly 15 years of reports, studies, policy changes, financial commitments, and regulations. The federal drinking water evaluation scheme is narrowly scoped, ignoring community level social factors, which may play a role in access to safe water in First Nations. This research used the 2006 Aboriginal Affairs and Northern Development Canada First Nations Drinking Water System Risk Survey data and the Community Well-Being Index, including labour force, education, housing, and income, from the 2006 Census. Bivariate analysis was conducted using the Spearman’s correlation, Kendall’s tau correlation, and Pearson’s correlation. Multivariable analysis was conducted using an ordinal (proportional or cumulative odds) regression model. Results showed that the regression model was significant. Community socioeconomic indicators had no relationship with drinking water risk characterization in both the bivariate and multivariable models, with the sole exception of labour force, which had a significantly positive effect on drinking water risk rankings. Socioeconomic factors were not important in explaining access to safe drinking water in First Nations communities. Improvements in the quality of safe water data as well as an examination of other community processes are required to address this pressing policy issue.

    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

    1999-01-01

    The ecosystem approach to human health is a holistic concept of health for both humans and the environment in which they live. This approach requires a holistic management of all facets of the ecosystem, be they physical, biologic, or indeed human-such as culture, economy, and developmental needs. This paradigm may at first glance seem theoretical and difficult to put into practice in everyday field research. However, using basic human needs, such as water and sanitation, as entry points illustrates how ecosystem health can indeed prove a powerful tool for sustainable development, promoting both human well-being and sustainable ecosystems. The authors describe the efforts of international agencies, particularly the International Development Research Centre (IDRC), to promote household safe drinking water security in developing countries. Essential to the success of these endeavors are strong partnerships with communities, research institutions, and donor agencies. The roles of these players are delineated. An important feature of IDRC projects, which is critical to their success, is the establishment of a simple, community-based water-quality monitoring program that the people can maintain with the limited resources available to them. The process and outcomes of past IDRC projects are presented and ongoing efforts are described.

    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.

    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.

    2007-01-01

    A detailed review of drinking water disease outbreaks over the past 30 years in 15 affluent countries produced over 70 case studies, some involving fatalities, which revealed a number of common factors in these disasters. Some of these outbreaks involved off-flavours, either as a driver for reducing disinfection and making the system vulnerable to pathogenic contamination or as an early warning of contamination that was not responded to with sufficient urgency or efficiency to avoid a disease outbreak. The characteristics of these outbreaks are recounted and the important link they reveal between aesthetically pleasing drinking water and safety is documented. Our analysis of common features in drinking water outbreaks also supports an argument that the failure of a water utility to be concerned about aesthetic factors makes such water supplies an inherently greater health risk for their consumers.

    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.

    The city of Milan, in western Tennessee, supplies drinking water to approximately 4,000 customers. Environmental investigations conducted by the US Army have detected low concentrations of RDX, a compound used in the manufacture of explosives, in two of the three city water supply wells. The RDX is traceable to the Milan Army Ammunition Plant nearby. The levels of RDX are being monitored and current trends indicate that levels in the wells will exceed the EPA Health Advisory Limits in the near term. In order to ensure an uninterrupted supply of acceptable quality drinking water for the city residents, the Army prepared and is implementing a Contingency Plan. The plan evaluated remedial alternatives to be implemented once a trigger level of RDX is reached, including institutional controls, installation of an RDX treatment system for the water supply system, and construction of a new well field. Institutional controls include: shutting down existing wells; continued monitoring; and promulgation of ground water ordinances. Treatment technologies evaluated include: ultraviolet light and hydrogen peroxide; or removal using granular activated carbon.

    Arsenic contamination of groundwater in Gangetic plain of Bihar, West Bengal in India and Bengal delta plain Bangladesh is shaping up as the greatest environmental health disaster in the current century. About 450 million combined population in these regions are at risk of developing adverse health effects due to arsenic contamination in groundwater. For an effective and sustainable mitigation, it is essential that we improve our understanding of fundamental processes of arsenic mobilization in sediments, biogeochemistry of arsenic in aquifer sediments and weigh a wide range of options for arsenic safe water for the vast population. In this paper, aspects of arsenic removal technology from groundwater in affected areas, sustainable development of household water filtration systems, deep aquifer water as potential arsenic safe water will be presented. In addition, sustainable development of water purification systems such as pond sand filtration (PSF), river sand filtration (RSF), rain water harvesting (RWH), dug well and their acceptability by the community will be discussed. A recent development of indigenous technology by local masons involves searching safe water through bore hole sediment color. The viability of this option in certain areas of Bangladesh will be discussed. Also, one of the household filtration systems approved by the government and locally known as SONO filter was recognized recently by the National Academy of Engineering -Grainger Challenge Prize for sustainability. Over 30, 000 of this unit were deployed in arsenic affected areas of Bangladesh. The affordability, ease of maintenance, social acceptability and environmental friendliness of all options will be addressed in the presentation.

    Background In May 2012, there were increasing diarrhoea cases and deaths reported from Nabua, Camarines Sur to the Philippines event-based surveillance system. An investigation was conducted to identify risk factors and determine transmission dynamics. Methods A suspected case was defined as a resident of Nabua with at least three episodes of watery diarrhoea per day from 16 March to 22 June 2012. A confirmed case was defined as a suspected case positive for Vibrio cholerae. An environmental investigation was conducted and rectal swabs and water samples sent to the national reference laboratory for bacterial isolation. A 1:2 case-control study matching for age and sex was conducted. Data were analysed using Epi Info. Results There were 309 suspected cases with two deaths, and the most affected age group was children under five years (45%). Eight cases were positive for Vibrio cholerae Ogawa El Tor and one for Non-01. Water samples were positive for faecal coliforms and Aeromonas caviae. The case-control study showed that cases had a higher odds than controls of using unchlorinated water sources (odds ratio [OR] = 3.6; 95% confidence interval [CI]:1.6–8.5) and having toilets located within 20 m of a septic tank (OR = 2.7; 95% CI: 1.4–5.3). In multivariate analysis, the only significant factor was drinking from piped water (OR = 0.21; 95% CI: 0.09–0.49). Discussion In this cholera outbreak, drinking-water from unchlorinated wells was a significant risk factor. Future cholera control efforts should include not just improving water and sanitation systems but also intensified behaviour change campaigns. PMID:26668761

    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.

    Background Education is one of the most important drivers behind helping people in developing countries lift themselves out of poverty. However, even when schooling is available absenteeism rates can be high. Recently interest has focussed on whether or not WASH interventions can help reduce absenteeism in developing countries. However, none has focused exclusively on the role of drinking water provision. We report a study of the association between absenteeism and provision of treated water in containers into schools. Methods and Findings We undertook a quasi-experimental longitudinal study of absenteeism rates in 8 schools, 4 of which received one 20 L container of treated drinking water per day. The water had been treated by filtration and ultraviolet disinfection. Weekly absenteeism rates were compared across all schools using negative binomial model in generalized estimating equations. There was a strong association with provision of free water and reduced absenteeism (Incidence rate ratio = 0.39 (95% Confidence Intervals 0.27–0.56)). However there was also a strong association with season (wet versus dry) and a significant interaction between receiving free water and season. In one of the intervention schools it was discovered that the water supplier was not fulfilling his contract and was not delivering sufficient water each week. In this school we showed a significant association between the number of water containers delivered each week and absenteeism (IRR = 0.98 95%CI 0.96–1.00). Conclusion There appears to be a strong association between providing free safe drinking water and reduced absenteeism, though only in the dry season. The mechanism for this association is not clear but may in part be due to improved hydration leading to improved school experience for the children. PMID:24632573

    Cryptosporidium is an opportunistic parasitic infection causing diarrhea, headache, abdominal cramping, vomiting, low-grade fever and sometimes death. It caused illness in 400,000 people in Milwaukee in 1993, and one hundred people died, the majority of them were living with AIDS. Since then, the Centers for Disease Control and Prevention (CDC) has issued water-safety guidelines for immunocompromised people. Boiling water will kill the cryptosporidium cysts, but people need to be aware that brushing their teeth or using ice cubes from untreated water could expose them to the parasite. Bottled water is not all safe; only that which is filtered in accordance with ANSI/NSF (American National Standards Institute/National Sanitation Foundation) Standard 53 will ensure safety. Home water filters must meet the requirements of the same standard. Currently available water filters under $200 are listed, and people are cautioned to exercise caution and wear gloves when changing the filters to prevent cryptosporidium exposure. PMID:11363358

    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.

    In response to concerns over hazardous chemicals in children’s products, Washington State passed the Children’s Safe Product Act (CSPA). CSPA requires manufacturers to report the concentration of 66 chemicals in children’s products. We describe a framework for the toxicological prioritization of the ten chemical groups most frequently reported under CSPA. The framework scores lifestage, exposure duration, primary, secondary and tertiary exposure routes, toxicokinetics and chemical properties to calculate an exposure score. Four toxicological endpoints were assessed based on curated national and international databases: reproductive and developmental toxicity, endocrine disruption, neurotoxicity and carcinogenicity. A total priority index was calculated from the product of the toxicity and exposure scores. The three highest priority chemicals were formaldehyde, dibutyl phthalate and styrene. Elements of the framework were compared to existing prioritization tools, such as the United States Environmental Protection Agency’s (EPA) ExpoCast and Toxicological Prioritization Index (ToxPi). The CSPA framework allowed us to examine toxicity and exposure pathways in a lifestage-specific manner, providing a relatively high throughput approach to prioritizing hazardous chemicals found in children’s products.

    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. PMID:24704952

    The groundwater in seven districts of West Bengal, India, covering an area of 37,000 km2 with a population of 34 million, has been contaminated with arsenic. In 830 villages/wards more than 1.5 million people, out of the total population, drink the arsenic-contaminated water. Safe water from a source having < 0.002 mg 1(-1) arsenic has been supplied for 2 years to five affected families comprising 17 members (eight of them with arsenical skin-lesions) of different age groups for impact assessment study in terms of loss of arsenic through urine, hair and nail. The study indicates random observable fluctuations of arsenic concentration in urine among members on different scheduled sampling days with a declining trend, particularly during the first 6 months. Furthermore, the investigation showed that despite having safe water for drinking and cooking, the study group could not avoid an intake of arsenic, time and again, through edible herbs grown in contaminated water, food materials contaminated through washing, and the occasional drinking of contaminated water. After minimizing the level of contamination, a noteworthy declining trend after 8 months was observed in urine, hair and nails in all the cases, but not to that level observed in a normal population, due to prevailing elevated background level of arsenic in the area. The eight members, who had already developed skin lesions, are far from recovering completely, indicating a long-lasting damage. Statistical interpretation of the data are considered.

    2013-08-01

    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.

    2015-01-01

    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.

  17. Safety evaluations under the proposed US Safe Cosmetics and Personal Care Products Act of 2013: animal use and cost estimates.

    2014-01-01

    The proposed Safe Cosmetics and Personal Care Products Act of 2013 calls for a new evaluation program for cosmetic ingredients in the US, with the new assessments initially dependent on expanded animal testing. This paper considers possible testing scenarios under the proposed Act and estimates the number of test animals and cost under each scenario. It focuses on the impact for the first 10 years of testing, the period of greatest impact on animals and costs. The analysis suggests the first 10 years of testing under the Act could evaluate, at most, about 50% of ingredients used in cosmetics. Testing during this period would cost about $ 1.7-$ 9 billion and 1-11.5 million animals. By test year 10, alternative, high-throughput test methods under development are expected to be available, replacing animal testing and allowing rapid evaluation of all ingredients. Given the high cost in dollars and animal lives of the first 10 years for only about half of ingredients, a better choice may be to accelerate development of high-throughput methods. This would allow evaluation of 100% of cosmetic ingredients before year 10 at lower cost and without animal testing. PMID:24468774

  19. Potential of using arsenic-safe aquifers as sustainable drinking water sources in arsenic-affected areas of Bengal basin, India and Bangladesh

    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.

  10. Health Impact of Supplying Safe Drinking Water on Patients Having Various Clinical Manifestations of Fluorosis in an Endemic Village of West Bengal

    PubMed Central

    Majumdar, Kunal K.; Sundarraj, Shunmuga N.

    2013-01-01

    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

    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

    Background Human African Trypanosomiasis (HAT) also called sleeping sickness is an infectious disease in humans caused by an extracellular protozoan parasite. The disease, if left untreated, results in 100% mortality. Currently available drugs are full of severe drawbacks and fail to escape the fast development of trypanosoma resistance. Due to similarities in cell metabolism between cancerous tumors and trypanosoma cells, some of the current registered drugs against HAT have also been tested in cancer chemotherapy. Here we demonstrate for the first time that the simple ester, ethyl pyruvate, comprises such properties. Results The current study covers the efficacy and corresponding target evaluation of ethyl pyruvate on T. brucei cell lines using a combination of biochemical techniques including cell proliferation assays, enzyme kinetics, phasecontrast microscopic video imaging and ex vivo toxicity tests. We have shown that ethyl pyruvate effectively kills trypanosomes most probably by net ATP depletion through inhibition of pyruvate kinase (Ki = 3.0±0.29 mM). The potential of ethyl pyruvate as a trypanocidal compound is also strengthened by its fast acting property, killing cells within three hours post exposure. This has been demonstrated using video imaging of live cells as well as concentration and time dependency experiments. Most importantly, ethyl pyruvate produces minimal side effects in human red cells and is known to easily cross the blood-brain-barrier. This makes it a promising candidate for effective treatment of the two clinical stages of sleeping sickness. Trypanosome drug-resistance tests indicate irreversible cell death and a low incidence of resistance development under experimental conditions. Conclusion Our results present ethyl pyruvate as a safe and fast acting trypanocidal compound and show that it inhibits the enzyme pyruvate kinase. Competitive inhibition of this enzyme was found to cause ATP depletion and cell death. Due to its ability to

    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

    2013-03-01

    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.

    A low-cost and highly efficient biosorbent was prepared by loading Al/Fe oxides onto tea waste and was tested for the ability to remove fluoride from drinking water. Key factors, including adsorbent dosage, initial fluoride concentration, contact time and initial pH of the biosorbent, were investigated. It was found that the solution pH played an important role in the removal of fluoride. The biosorbent combinations Tea-Al or Tea-Al-Fe could reduce the fluoride concentration to below 1.5 mg/L in the drinking water, a level which meets the drinking water standard recommended by the World Health Organization (WHO). In addition, the residual concentrations of Al and Fe in the drinking water after Tea-Al-Fe treatment were below the standards set by WHO when treatment was conducted at pH values ranging from 5.0 to 10.0. The experimental data were analyzed using two-parameter theoretical models. The maximum fluoride adsorption capacities for the original tea, Tea-Fe, Tea-Al and Tea-Al-Fe biosorbents were 3.83, 10.47, 13.79 and 18.52 mg/g, respectively. These findings demonstrate the suitability of a prepared biosorbent based on tea waste for the removal of fluoride from drinking water.

    1976-07-01

    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. PMID:937609

    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 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.

    Introduction and Aims For consumers to follow drinking guidelines and limit their risk of negative consequences they need to track their ethanol consumption. This paper reviews published research on the ability of consumers to utilise information about the alcohol content of beverages when expressed in different forms e.g. in standard drinks or units versus percentage alcohol content.. Design and Methods A review of the literature on standard drink definitions and consumer understanding of these, actual drink pouring, use of standard drinks in guidelines and consumer understanding and use of these. Results Standard drink definitions vary across countries and typically contain less alcohol than actual drinks. Drinkers have difficulty defining and pouring standard drinks with over-pouring being the norm such that intake volume is typically underestimated. Drinkers have difficulty using percentage alcohol by volume and pour size information in calculating intake but can effectively utilise standard drink labeling to track intake. Discussion and Conclusions Standard drink labeling is an effective but little used strategy for enabling drinkers to track their alcohol intake and potentially conform to safe or low risk drinking guidelines.

  18. Water, Water Everywhere but is it Safe to Drink? Some Detrimental Health Effects Associated with Consumption of Groundwater Enriched in Naturally-Occurring Contaminants

    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

  20. The Effect of Philadelphia and Pennsylvania Clean Indoor Air Act on Food Services and Drinking Places Sales and Numbers, 1998-2011

    Fisher, Monica A.

    2013-01-01

    Introduction Philadelphia enacted its Clean Indoor Air Act (CIAA) nearly 2 years before the statewide CIAA. In this study, we assessed the economic impact of CIAAs on 4 types of food services and drinking places and addressed the predominant limitation of previous pre–post ban studies, namely the lack of control for confounders and changes in secular trends over time. Methods We analyzed data from Pennsylvania Department of Revenue Quarterly 1998–2011 taxable county-level revenue sales and number of food services and drinking places. Region-specific and type-specific adjusted sales and number of food services and drinking places accounted for consumer spending as a general economic indicator. Segmented regression analysis of interrupted time-series methodology assessed changes in trend and level. Results Pennsylvania CIAA had no significant effect on adjusted sales or numbers except for an increase in sales in Philadelphia for limited-service eating places and in the surrounding 4 counties for special food services. Philadelphia CIAA was associated with an increase in adjusted numbers of full-service restaurants in Philadelphia and the rest of the state, special food services in Philadelphia, and drinking places in the rest of the state, and a decrease in the number of special food services in the surrounding counties. Philadelphia CIAA had no significant effect on adjusted sales except for an increase in special food services in the rest of the state. Conclusion Overall, CIAAs had no negative business-related impact and, for the most part, suggest a positive impact on restaurant sales and numbers. Our results provide further support for comprehensive CIAA ordinance for restaurants. PMID:24286275

    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

    PubMed

    2016-03-15

    Adropin, a recently described peptide hormone produced in the brain and liver, has been reported to have physiologically relevant actions on glucose homeostasis and lipogenesis, and to exert significant effect on endothelial function. We describe a central nervous system action of adropin to inhibit water drinking and identify a potential adropin receptor, the orphan G protein-coupled receptor, GPR19. Reduction in GPR19 mRNA levels in medial basal hypothalamus of male rats resulted in the loss of the inhibitory effect of adropin on water deprivation-induced thirst. The identification of a novel brain action of adropin and a candidate receptor for the peptide should extend and accelerate the study of the potential therapeutic value of adropin or its mimetics for the treatment of metabolic disorders.

    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.

  16. 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.

    1993-07-15

    EPA prepared the report in response to the Congressional mandate in Public Law 102-389 (the Chafee-Lautenberg Amendment to EPA's Appropriation Bill, enacted October 6, 1992) which directs the Administrator of the US Environmental Protection Agency (EPA) to report to Congress on EPA's findings regarding the risks of human exposure to radon, the costs for controlling or mitigating that exposure, and the risks posed by treating water to remove radon. The Chafee-Lautenberg Amendment called for an explicit multimedia comparison of the risks from radon in indoor air and drinking water. Congress placed the requirement on the Agency because of the concern voiced in the United States over the costs to be incurred by public water systems in the control of radon in drinking water while a larger threat from indoor air was not being addressed except through voluntary measures. Amendments to the Safe Drinking Water Act in 1986 called for the regulation of radon in drinking water.

    2003-01-01

    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

    The main objectives of health care for people with AIDS are to help them adjust to changing sexual status and to provide them with information on safe sex. Sections consider the risks of various types of sexual activity and safe sex education. With regard to the risk of transmitting or contracting HIV, sexual activities may be high risk, medium risk, low risk, or no risk. High-risk activities include unprotected anal or vaginal intercourse, oral-anal sexual contact, sharing sex toys, and traumatic sexual activity. Medium-risk activities include anal and vaginal intercourse using a latex condom with or without spermicide, and sex using a vaginal diaphragm or contraceptive vaginal sponge. Oral sex on a woman or oral sex on a man without ejaculation into the mouth are low-risk activities. Mutual masturbation, erotic touching, caressing and massage, kissing and non-genital licking pose no risk of infection. All general practitioners and family physicians should teach about safe sex. Prevention messages may be conveyed through individual and social counseling as well as with printed media and other forms of mass media. Messages should definitely reach prostitutes and brothel owners, as well as pre-pubertal children and older youths. PMID:8207282

    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. PMID:16493893

  9. 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.

    Following more than a decade of scientific debate about the setting of a standard for {sup 222}Rn 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 {sup 222}Rn concentration and the increment of {sup 222}Rn 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.

    A new four-bed unit was opened in Bristol, UK, in 2014, for people detained under section 136 of the Mental Health Act. Police bring individuals posing a risk to themselves or others to a Place of Safety (PoS) in order to receive a mental health assessment. Individuals may be held for up to 72 hours, but cannot receive treatment against their will, unless assessed as lacking the capacity to refuse treatment. Issues requiring medical input arose in more than a third of patients, yet there was little guidance for trainees around the PoS. We conducted a survey which confirmed that robust clinical guidance was needed for junior doctors around medical assistance in this unique environment. We identified specific concerns around patient safety in relation to alcohol withdrawal, uncertainties around legislation and lack of clarity of who to call out of hours. Trainees felt they were working outside of their expertise. We collaborated with a variety of professionals to produce clinical guidance in line with best evidence, and made this easily accessible. We also gained a consensus that more experienced core trainees (SHOs) in Psychiatry should be the first point of contact. We then conducted a survey in June 2015, and found that doctors covering the PoS now felt there was sufficient guidance on most clinical scenarios, 100% consensus on who to contact and improved confidence in their ability to manage issues arising. In August 2015 we held an informal training session for the new intake of trainees on the rota. A subsequent survey revealed similarly positive results. Through this project, we were able to identify defects in a system, provide needed guidance to enable safer and more equitable care to a vulnerable group, and foster closer collaboration between junior doctors and managers in the design and use of services.

    We construct a new inflation model in which the standard model Higgs boson couples minimally to gravity and acts as the inflaton. Our construction of Higgs inflation incorporates the standard model with Einstein gravity which exhibits asymptotic safety in the ultraviolet region. The slow roll condition is satisfied at large field value due to the asymptotically safe behavior of Higgs self-coupling at high energies. We find that this minimal construction is highly predictive, and is consistent with both cosmological observations and collider experiments.

    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

    The Safe Drinking Water Act and its Amendments (SDWAA) will pose a massive challenge for the drinking-water industry in the United States. As the SDWAA regulations reach implementation, increasing effort will be devoted to understanding the factors causing deterioration of water quality between treatment and consumption. A cooperative study involving the U.S. EPA, the University of Michigan, and the South Central Connecticut Regional Water Authority (RWA) demonstrated and validated the use of modeling techniques in the RWA distribution system. Models are used to predict the propagation of chlorine residual in one portion of the RWA system. It is found that residuals varied widely both spatially and temporally. Long residence times in storage tanks caused residual disinfection concentrations to be low or nonexistent during discharge cycles. It was found that system operation has a significant effect on the distribution and concentration of chlorine residuals in the system.

    This work presents a model for estimating global access to drinking water that meets World Health Organization (WHO) water quality guidelines. The currently accepted international estimate of global access to safe water, the WHO and United Nations Children's Fund's (UNICEF) Joint Monitoring Program (JMP) report, estimates the population with access to water service infrastructure that is classified as improved and unimproved. The JMP report uses access to improved water sources as a proxy for access to safe water, but improved water sources do not always meet drinking water quality guidelines. Therefore, this report likely overestimates the number of people with access to safe water. Based on the JMP estimate, the United Nations has recently announced that the world has reached the Millennium Development Goal (MDG) target for access to safe water. Our new framework employs a statistical model that incorporates source water quality, water supply interruptions, water storage practices, and point of use water treatment to estimate access to safe water, resulting in a figure that is lower than the JMP estimate of global access to safe water. We estimate that at least 28% of the world does not have access to safe water today, as compared to the JMP estimate of 12%. These findings indicate that much more work is needed on the international scale to meet the MDG target for access to safe water.

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

    Boorman, G A

    1999-01-01

    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.

    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.

    After almost 20 years of experience with implementing the Safe Drinking Water Act and eight with Amendments to the Act, the individual states within the United States have gained valuable experience while trying to reconcile the legal mandates provided by the statutes with the science underlying them. This paper presents four different topics illustrating the problems of reconciling these two issues in the regulation of toxic chemicals in drinking waters. It presents these from the perspectives of the states of Massachusetts, Rhode Island, Connecticut, and New Jersey and offers suggestions for improved program efficiency based on considerations of comparative human health risks. The approach and schedule for controlling toxic chemicals used through 1994 are first examined and a recommendation is made for more flexibility in the rate at which chemicals are regulated. Recent U.S. EPA proposals to more stringently control radon in drinking waters are presented in the context of all sources of radon exposures, illustrating the intersection of science, laws, and economic consequences of regulatory initiatives. Inhalation and dermal exposures as a result of using chemically contaminated drinking waters are then discussed with the suggestion of the possible underprotectiveness of some present standards. Finally, the difficulty faced by the states and federal government in the control of naturally occurring arsenic exposures through drinking water is also presented and an argument is made for more local flexibility in the application of health-based standards.

    The Michigan Safe Drinking Water Act (Act 399) was enacted in 1976 and enables the Michigan Department of Environmental Quality (DEQ) to maintain the state's authority over drinking water in the state. The DEQ also contracts with local health departments to maintain non-community programs in each county. Private water wells throughout the state are clearly the most troublesome for users and regulators. An abundant array of contaminants (e.g., pesticides, metals, etc.) may impact wells without the user's knowledge. Most private wells are only inspected when they are installed and have no further regulatory requirements. With regards to contaminants in public systems, lead is problematic. Irregardless of the source or treatment, the piping infrastructure leading to and inside the home can be a source affecting the quality. Thus, the problem of lead in drinking water can be from the service lines, the pipes inside the home, the solder connecting the pipes, or in some case the treatment chemicals used for disinfection.

    The Michigan Safe Drinking Water Act (Act 399) was enacted in 1976 and enables the Michigan Department of Environmental Quality (DEQ) to maintain the state's authority over drinking water in the state. The DEQ also contracts with local health departments to maintain non-community programs in each county. Private water wells throughout the state are clearly the most troublesome for users and regulators. An abundant array of contaminants (e.g., pesticides, metals, etc.) may impact wells without the user's knowledge. Most private wells are only inspected when they are installed and have no further regulatory requirements. With regards to contaminants in public systems, lead is problematic. Irregardless of the source or treatment, the piping infrastructure leading to and inside the home can be a source affecting the quality. Thus, the problem of lead in drinking water can be from the service lines, the pipes inside the home, the solder connecting the pipes, or in some case the treatment chemicals used for disinfection.

  8. A look at the federal drinking water revolving loan fund proposals

    1994-05-01

    The lack of funding is a primary reason behind the difficulty many water systems have with installing needed treatment, upgrading existing systems, or making other improvements necessary to meet new regulations set under the Safe Drinking Water Act (SDWA). Providing a mechanism for federal funding for drinking water systems is a key objective of pending legislation. Current legislative proposals are patterned after the state revolving loan fund (SRF) concept used for funding wastewater treatment facilities under the Clean Water Act (CWA). The federal government would provide capitalization grants to states that meet the minimum requirements set by the US Environmental Protection Agency (USEPA). The states would provide loans and other financial assistance to eligible water systems who would repay the loans, thereby perpetuating the fund. This article compares the SRF proposals currently pending in Congress.

    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. PMID:26324872

    As part of a program for evaluation of environmental contaminants in drinking water, risk assessments are being conducted to develop Public Health Goals (PHGs) for chemicals in drinking water, based solely on public health considerations. California's Safe Drinking Water Act of 1996 mandated the development of PHGs for over 80 chemicals by 31 December 1999. The law allowed these levels to be set higher or lower than federal maximum contaminant levels (MCLs), including a level of zero if data are insufficient to determine a specific level. The estimated safe levels and toxicological rationale for the first 26 of these chemicals are described here. The chemicals include alachlor, antimony, benzo[a]pyrene, chlordane, copper, cyanide, dalapon, 1,2-dichlorobenzene, 1,4-dichlorobenzene, 2,4-D, diethylhexylphthalate, dinoseb, endothall, ethylbenzene, fluoride, glyphosate, lead, nitrate, nitrite, oxamyl, pentachlorophenol, picloram, trichlorofluoromethane, trichlorotrifluoroethane, uranium and xylene(s). These risk assessments are to be considered by the State of California in revising and developing state MCLs for chemicals in drinking water (which must not exceed federal MCLs). The estimates are also notable for incorporation or consideration of newer guidelines and principles for risk assessment extrapolations. PMID:11139167

    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.

  18. The risks of drinking water

    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.

  20. Lead in drinking water and human blood lead levels in the United States.

    PubMed

    Brown, Mary Jean; Margolis, Stephen

    2012-08-10

    Lead is a pervasive environmental contaminant. The adverse health effects of lead exposure in children and adults are well documented, and no safe blood lead threshold in children has been identified. Lead can be ingested from various sources, including lead paint and house dust contaminated by lead paint, as well as soil, drinking water, and food. The concentration of lead, total amount of lead consumed, and duration of lead exposure influence the severity of health effects. Because lead accumulates in the body, all sources of lead should be controlled or eliminated to prevent childhood lead poisoning. Beginning in the 1970s, lead concentrations in air, tap water, food, dust, and soil began to be substantially reduced, resulting in significantly reduced blood lead levels (BLLs) in children throughout the United States. However, children are still being exposed to lead, and many of these children live in housing built before the 1978 ban on lead-based residential paint. These homes might contain lead paint hazards, as well as drinking water service lines made from lead, lead solder, or plumbing materials that contain lead. Adequate corrosion control reduces the leaching of lead plumbing components or solder into drinking water. The majority of public water utilities are in compliance with the Safe Drinking Water Act Lead and Copper Rule (LCR) of 1991. However, some children are still exposed to lead in drinking water. EPA is reviewing LCR, and additional changes to the rule are expected that will further protect public health. Childhood lead poisoning prevention programs should be made aware of the results of local public water system lead monitoring measurement under LCR and consider drinking water as a potential cause of increased BLLs, especially when other sources of lead exposure are not identified.

    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.

    After a general discussion of the factors contributing to maternal mortality and morbidity, a solution to both of these problems is suggested for India: an initiative at the district level to improve support, supervision, training, essential midwifery and obstetric care. The general causes of the 200 or more times higher maternal morality risks in developing countries act throughout the woman's lifetime: powerlessness, illiteracy, malnutrition, deficiency of calcium, vitamin D and iron, heavy physical labor, unchecked fertility, lack of prenatal and obstetric care and illegal abortion. The most common causes of maternal morality and morbidity, eclampsia, obstructed labor, hemorrhage and sepsis, have been prevented in developed countries and in China. We know how to prevent them, by technical support and management at the district level. 4 elements are required: 1) adequate primary health care, food and universal family planning; 2) prenatal care and nutrition with referral if needed; 3) assistance of a trained person at every childbirth; 4) access to obstetric care for those at high risk. Rather than spend money or urban specialized hospital centers, half to 2/3 of all fatal complications of childbirth can be eliminated by local hospitals with the ability to do basic obstetrics such as caesareans and blood transfusions. There is a need for further health systems research in the given locale, but what we need now is an initiative on making pregnancy and childbirth safe for all women. PMID:3420000

    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.

    Groundwater has been considered a safe source for drinking water protected against surface contamination. However, a number of reports about chemical and microbiological contamination have disproved this assumption. Besides hygienical monitoring, little is known about the microbiology of ground- and drinking water. The purpose of this paper is to give a review about the main fields of investigation concerning microbial activity in ground- and drinking-water-action. The hygienical relevant topics are: survival and transport of microorganisms, microbiological degradation of organic pollutants, turn-over of nitrogen compounds, oxidation and reduction of iron and manganese and development of methods for microbiological water examination.

    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.

    SciTech Connect

    Hauchman, F.S.

    1992-01-01

    The Environmental Protection Agency's (EPA) Health Effects Research Laboratory (HERL) provides chemical-specific data and scientific methods that are used by the EPA Office of Water in the development of regulations required by the Safe Drinking Water Act. To determine the chemical and microbial contaminants in drinking water that are of greatest public health concern, HERL conducts hazard identification and dose-response research in humans, animals, and in vitro. HERL conducts studies on pharmacokinetics and mechanisms of action to facilitate the extrapolation of toxicity data from animals to humans. Characterization of the risks associated with human exposure to contaminants in drinking water involves a multi-laboratory/office effort to incorporate information on hazard, dose-response, and exposure into chemical and microbial risk models. The many uncertainties in the underlying health effects data base and in the models used for assessing chemical and microbial risks highlight the need for a strong drinking water health research program in the years to come.

  1. Effect of turbidity on chlorination efficiency and bacterial persistence in drinking water.

    PubMed

    LeChevallier, M W; Evans, T M; Seidler, R J

    1981-07-01

    To define interrelationships between elevated turbidities and the efficiency of chlorination in drinking water, experiments were performed to measure bacterial survival, chlorine demand, and interference with microbiological determinations. Experiments were conducted on the surface water supplies for communities which practice chlorination as the only treatment. Therefore, the conclusions of this study apply only to such systems. Results indicated that disinfection efficiency (log10 of the decrease in coliform numbers) was negatively correlated with turbidity and was influenced by season, chlorine demand of the samples, and the initial coliform level. Total organic carbon was found to be associated with turbidity and was shown to interfere with maintenance of a free chlorine residual by creating a chlorine demand. Interference with coliform detection in turbid waters could be demonstrated by the recovery of typical coliforms from apparently negative filters. The incidence of coliform masking in the membrane filter technique was found to increase as the turbidity of the chlorinated samples increased. the magnitude of coliform masking in the membrane filter technique increased from less than 1 coliform per 100 ml in water samples of less than 5 nephelometric turbidity units to greater than 1 coliform per 100 ml in water samples of greater than 5 nephelometric turbidity units. Statistical models were developed to predict the impact of turbidity on drinking water quality. The results justify maximum contaminant levels for turbidity in water entering a distribution system as stated in the National Primary Drinking Water Regulations of the Safe Drinking Water Act.

  2. Binge Drinking Intensity

    PubMed Central

    Esser, Marissa B.; Kanny, Dafna; Brewer, Robert D.; Naimi, Timothy S.

    2015-01-01

    Background Binge drinking (≥4 drinks for women; ≥5 drinks for men, per occasion) is responsible for more than half of the estimated 80,000 U.S. deaths annually and three-quarters of the $223.5 billion in costs in 2006. Binge drinking prevalence is assessed more commonly than binge drinking intensity (i.e., number of drinks consumed per binge episode). Risk of binge drinking–related harm increases with intensity, and thus it is important to monitor. The largest number of drinks consumed is assessed in health surveys, but its usefulness for assessing binge intensity is unknown. Purpose To assess the agreement between two potential measures of binge drinking intensity: the largest number of drinks consumed by binge drinkers (maximum-drinks) and the total number of drinks consumed during their most recent binge episode (drinks-per-binge). Methods Data were analyzed from 7909 adult binge drinkers from 14 states responding to the 2008 Behavioral Risk Factor Surveillance System (BRFSS) binge drinking module. Mean and median drinks-per-binge from that module were compared to mean and median maximum-drinks. Analyses were conducted in 2010–2011. Results Mean (8.2) and median (5.9) maximum-drinks were strongly correlated with mean (7.4) and median (5.4) drinks-per-binge (r=0.57). These measures were also strongly correlated across most sociodemographic and drinking categories overall and within states. Conclusions The maximum-drinks consumed by binge drinkers is a practical method for assessing binge drinking intensity and thus can be used to plan and evaluate Community Guide–recommended strategies for preventing binge drinking (e.g., increasing the price of alcoholic beverages and regulating alcohol outlet density).

    1983-03-01

    Ideally, a circuit is said to be fail safe, if for every possible failure configuration, the circuit results in a safe side output. In order to guarantee safe side failures, it is imperative that the circuit detects any faults within it. A suitable procedure for doing this can be based on an error detecting code, such as the K out of N code. A number of circuit types are considered, taking into account a fault tolerant circuit, a fault secure circuit, a self testing circuit, a self checking circuit, a self checking checker, and a fail safe circuit. Attention is given to the realization of combinational circuits, aspects of safety and reliability, sequential circuits, the realization of sequential circuits, the occurrence of clock failure, and the design procedure.

    Keeping in mind the key concepts of heat dissipation and using sound strategies for heat acclimatization and fluid replacement can help keep participants and spectators safe during hot-weather sports activities. Acclimatization to heat requires 10 to 14 days of training. Prudent hydration involves drinking plenty of fluid 2 hours before exercise, 5 to 10 oz of fluid every 15 minutes during exercise, and fluids with increased sodium content after exercise. A sidebar on environmental conditions and heat-related medical encounters during the 1996 Summer Olympics in Atlanta illustrates the importance of prevention strategies at the individual and event level.

    The Osage UIC Program was developed to address and regulate injection wells in Osage County, Oklahoma. It was initiated to protect the environment according to the Safe Drinking Water Act (SDWA) but was tailored it allow operators to continue using injection wells with a minimum amount of additional compliance with the new law. This meant that costly repairs or modifications to the wells were avoided in most cases. In addition, various methods have been developed to further fulfill the regulatory requirements with cost savings in mind. Newly permitted wells have also experienced positive changes to make pressure and volume modification requests possible, and to make other permit changes faster and more efficient. The allowance of modifications to permits has increased oil production without compromising the environment.

  15. 226Ra and 228Ra in Iowa drinking water.

    The University Hygienic Laboratory has been performing radiochemical analyses on drinking water in the state of Iowa for over 20 yr. Approximately one half of the 1250 community water supplies that exist in Iowa have been sampled roughly once every 3 yr for the past decade. Originally, raw and finished waters that showed a gross alpha activity of greater than or equal to 3.0 pCi/L were analyzed for 226Ra, but starting in July 1976, finished waters were analyzed for both 226Ra and 228Ra if the gross alpha activity was greater than or equal to 2.0 pCi/L. As of 10 June 1981, 604 community water supplies had submitted composited samples that have been analyzed for gross alpha, 226Ra, and 228Ra concentrations in compliance with the federal Safe Drinking Water Act (Public Law 93-523). Approximately 10% of these supplies were found to exceed the EPA-established maximum contaminant level (MCL) for 226Ra plus 228Ra of 5 pCi/L. The results revealed, consistent with several other investigators (Mc81; Mi80; Mic80), that some supplies had higher concentrations of 228Ra than of 226Ra. It was also concluded, in agreement with McCurdy and Mellor (Mc81), that some ground water samples cannot be accurately measured for gross alpha activity due to their high dissolved solids content.

    Many efforts to prevent alcohol-related harm are aimed at reducing risk drinking. This article outlines the many conceptual and methodological challenges to defining risk drinking. It summarizes recent evidence regarding associations of various aspects of alcohol consumption with chronic and acute alcohol-related harms, including mortality, morbidity, injury, and alcohol use disorders, and summarizes the study designs most appropriate to defining risk thresholds for these types of harm. In addition, it presents an international overview of low-risk drinking guidelines from more than 20 countries, illustrating the wide range of interpretations of the scientific evidence related to risk drinking. This article also explores the impact of drink size on defining risk drinking and describes variation in what is considered to be a standard drink across populations. Actual and standard drink sizes differ in the United States, and this discrepancy affects definitions of risk drinking and prevention efforts. PMID:22330212

    Consumption of energy drinks has been increasing dramatically in the last two decades, particularly amongst adolescents and young adults. Energy drinks are aggressively marketed with the claim that these products give an energy boost to improve physical and cognitive performance. However, studies supporting these claims are limited. In fact, several adverse health effects have been related to energy drink; this has raised the question of whether these beverages are safe. This review was carried out to identify and discuss the published articles that examined the beneficial and adverse health effects related to energy drink. It is concluded that although energy drink may have beneficial effects on physical performance, these products also have possible detrimental health consequences. Marketing of energy drinks should be limited or forbidden until independent research confirms their safety, particularly among adolescents. PMID:26715927

    The Environmental Protection Agency (EPA), under the requirements of the Safe Drinking Water Act Section 1401 and 1412, P.L. 99-339, as amended in 1986, has proposed a National Primary Drinking Water Regulation (NPDWR) pertaining to the contamination of public-water systems by inorganic chemical contaminants. The proposed IOCs Rule includes information collection requirements for eight inorganic chemicals -- asbestos, barium, cadmium, chromium, mercury, nitrate, nitrite, and selenium. The information collection request analyzes the information burden imposed on public-water systems and States as a result of the regulation. EPA is proposing only to regulate source-related inorganics under this rule, as opposed to inorganics which predominately occur as corrosion by-products and naturally occurring copper and lead are analyzed in the RIA and ICR for lead and corrosion by-products. Note also that EPA has already promulgated a NPDWR for fluoride.

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.

    Western society has undergone a vast sociological change during the 20th century in terms of the value of sexuality. Sexual choice has gained a new legitimacy never before experienced. There is less guilt surrounding issues of sexuality and it is now common place to hear and see explicit discussions about sex in the mass media. This acceptance has undoubtedly encouraged many people to be more daring and promiscuous in their sexual activities. Proof of this can be seen in the increase is the incidence of sexually transmitted diseases (STDs). Presently there are more than 20 epidemiologically significant diseases that are sexually transmitted. Beyond the 5 old standards of gonorrhea, syphilis, chancroid, lyphogranuloma venereum, and granuloma inguinala STDs now include: chlamydia trachomatis, genital herpes, human papillomavirus, human immunodeficiency virus, genital mycoplasms, cytomegalovirus, hepatitis, vaginitis, enteric infections, and ectoparasitic diseases. Keeping all this in mind, the question of the ethics of safe sex must be addressed. In many countries, the governments have undertaken large public education programs to encourage safe sex practices. All these programs a founded upon two ideas: that safe sex should be promoted free of any ethical discussions or considerations, and that technology alone, the condom, will protect the public from the problem of STDs. However these campaigns will fail to protect the public unless they try to intervene at some level other than the mechanical aspect of the sex act itself. Condoms have failure rates too high to be relied upon as the sole means of protecting the public. Sex education for children and an inclusion of the ethical aspects of sex, now that the consequences can mean death, must be included in these government programs if they are to be successful.

    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.

    Some volatile N-nitrosamines, primarily N-nitrosodimethylamine (NDMA), are recognized as products of drinking water treatment at ng/L levels and as known carcinogens. The U.S. EPA has identified the N-nitrosamines as contaminants being considered for regulation as a group under the Safe Drinking Water Act. Nitrosamines are common dietary components, and a major database (over 18,000 drinking water samples) has recently been created under the Unregulated Contaminant Monitoring Rule. A Monte Carlo modeling analysis in 2007 found that drinking water contributed less than 2.8% of ingested NDMA and less than 0.02% of total NDMA exposure when estimated endogenous formation was considered. Our analysis, based upon human blood concentrations, indicates that endogenous NDMA production is larger than expected. The blood-based estimates are within the range that would be calculated from estimates based on daily urinary NDMA excretion and an estimate based on methylated guanine in DNA of lymphocytes from human volunteers. Our analysis of ingested NDMA from food and water based on Monte Carlo modeling with more complete data input shows that drinking water contributes a mean proportion of the lifetime average daily NDMA dose ranging from between 0.0002% and 0.001% for surface water systems using free chlorine or between 0.001% and 0.01% for surface water systems using chloramines. The proportions of average daily dose are higher for infants (zero to six months) than other age cohorts, with the highest mean up to 0.09% (upper 95th percentile of 0.3%). PMID:23786353

    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.

    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. PMID:3911419

    The supply of clean drinking water is a major, and relatively recent, public health milestone. Control of microbial growth in drinking water distribution systems, often achieved through the addition of disinfectants, is essential to limiting waterborne illness, particularly in immunocompromised subpopulations. Recent inquiries into the microbial ecology of distribution systems have found that pathogen resistance to chlorination is affected by microbial community diversity and interspecies relationships. Research indicates that multispecies biofilms are generally more resistant to disinfection than single-species biofilms. Other recent findings are the increased survival of the bacterial pathogen Legionella pneumophila when present inside its protozoan host Hartmannella vermiformis and the depletion of chloramine disinfectant residuals by nitrifying bacteria, leading to increased overall microbial growth. Interactions such as these are unaccounted for in current disinfection models. An understanding of the microbial ecology of distribution systems is necessary to design innovative and effective control strategies that will ensure safe and high-quality drinking water.

    Binge drinking is a pattern of heavy drinking which is observed all over Europe. The term Binge drinking implies a lot of different meanings to different people. The most popular definition used for this term is five or more 'standard drinks' in a single occasion. Binge drinking is different from intoxication, although this kind of heavy alcohol consumption can be lead to intoxication. This condition is manifested by different signs, for example slurred speech. Binge drinking is very common among the European population. In 2006 some 80 million Europeans aged 15 plus reported this kind of alcohol consumption patterns. European surveys showed that there is an increase of binge drinking across Europe amongst young people (15-16 years) old since 1995. The consequences of binge drinking contain acute and chronic effects, which are caused by long term alcohol use. The individual risks are brain damage, suicide, sexually transmitted diseases, etc. It has also an impact on harm to others than the drinkers. This includes violence and crime, accidents, etc. Each year in the European Union 2000 homicides are related to heavy drinking. There a lot of effective measures to reduce binge drinking. Strong evidence is shown by drink-driving laws, tax, reduced access to and availability of alcohol, brief interventions such as physician advice and advertising controls. PMID:18173097

    The Safe Drinking Water Act of 1974 regulates water quality in public drinking water supply systems but does not pertain to private domestic wells, often found in rural areas throughout the country. The recent decision to tighten the drinking water standard for arsenic from 50 parts per billion (ppb) to 10 ppb may therefore affect some households in rural communities, but may not directly reduce health risks for those on private wells. The article reports results from a survey conducted in a U.S. arsenic hot spot, the rural area of Churchill County, Nevada. This area has elevated levels of arsenic in groundwater. We find that a significant proportion of households on private wells are consuming drinking water with arsenic levels that pose a health risk. The decision to treat tap water for those on private wells in this area is modeled, and the predicted probability of treatment is used to help explain drinking water consumption. This probability represents behaviors relating to the household's perception of risk.

    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

    Nine analytical methods covering 54 organic contaminants which may be present in drinking water or drinking water sources are described in detail. Seven of these methods cover compounds designated for regulation under the Safe Drinking Water Act Amendments of 1986. Regulations for this group are in the proposal stages with promulgation scheduled for June 1992. The other two methods are for chlorination disinfection byproducts and may be regulated as part of EPA's disinfectants and disinfectant byproducts rule scheduled for proposal early in 1992. Most of the analytes may be classified as non-volatile and three of the methods entail separations by high performance liquid chromatography. The remainder employ capillary column gas chromatography. One of these requires detection of a potentially very toxic contaminant, 2,3,7,8-tetrachlorodibenzo-p-dioxin, at the low parts per trillion level. Labeled isotopes of this analyte are employed as tracers and high resolution mass spectrometry is required for detection and unambiguous identification. Three of the methods herein offer new and simplified liquid-solid extraction procedures, a trend which is likely to become even more pronounced in the future.

    Water quality studies often include the analytical challenge of incorporating censored data and quantifying error of estimation. Many analytical methods exist for estimating distribution parameters when censored data are present. This paper presents a Bayesian-based hierarchical model for estimating the national distribution of the mean concentrations of chemicals occurring in U.S. public drinking water systems using fluoride and thallium as examples. The data used are Safe Drinking Water Act compliance monitoring data (with a significant proportion of left-censored data). The model, which assumes log-normality, was evaluated using simulated data sets generated from a series of Weibull distributions to illustrate the robustness of the model. The hierarchical model is easily implemented using the Markov chain Monte Carlo simulation method. In addition, the Bayesian method is able to quantify the uncertainty in the estimated cumulative density function. The estimated fluoride and thallium national distributions are presented. Results from this study can be used to develop prior distributions for future U.S. drinking water regulatory studies of contaminant occurrence. PMID:14998034

    Pesticide residues in drinking water can vary significantly from day to day. However, drinking water quality monitoring performed under the Safe Drinking Water Act (SDWA) at most community water systems (CWSs) is typically limited to four data points per year over a few years. Due to limited sampling, likely maximum residues may be underestimated in risk assessment. In this work, a statistical methodology is proposed to study the cross-sectional and longitudinal uncertainties in observed samples and their propagated effect in risk estimates. The methodology will be demonstrated using data from 16 CWSs across the US that have three independent databases of atrazine residue to estimate the uncertainty of risk in infants and children. The results showed that in 85% of the CWSs, chronic risks predicted with the proposed approach may be two- to four-folds higher than that predicted with the current approach, while intermediate risks may be two- to three-folds higher in 50% of the CWSs. In 12% of the CWSs, however, the proposed methodology showed a lower intermediate risk. A closed-form solution of propagated uncertainty will be developed to calculate the number of years (seasons) of water quality data and sampling frequency needed to reduce the uncertainty in risk estimates. In general, this methodology provided good insight into the importance of addressing uncertainty of observed water quality data and the need to predict likely maximum residues in risk assessment by considering propagation of uncertainties.

    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.

    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. PMID:21728036

    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.

    Safe N’ Sound is a computer-based tool that prioritizes key injury risks for toddlers and infants and provides tailored feedback. The program was implemented in 5 pediatric sites. Caregiver risk behaviors were analyzed and compared with corresponding national and state morbidity and mortality data. The priority risks identified were generally consistent with the incidence of injury. Frequencies of several risk behaviors varied across sites and differences were observed across ages. Use of a prioritization scheme may facilitate risk behavior counseling and reasonably result in a decrease in injury mortality or morbidity. PMID:22617412

    Although the 103rd Congress made substantial progress towards passage of Clean Water Act amendments and reauthorization legislation and other environmental bills, including Safe Drinking Water Act reauthorization, 1994 resulted in no substantial new environmental legislation. Regulatory developments proceeded slowly as well, the most significant water regulatory issues on the federal level potentially impacting oil and gas operations being the anticipated issuance of a multi-sector storm water general permit and continuing EPA study of effluent limitations for coastal oil and gas extraction. The several Oil Pollution Act regulatory developments over the last year, including vessel financial responsibility, oil spill response planning, and revisions to the National Contingency Plan are not addressed in this paper.

    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

    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.

    Software products evolve over time. Sometimes they evolve by adding new features, and sometimes by either fixing bugs or replacing outdated implementations with new ones. When software engineers fail to anticipate such evolution during development, they will eventually be forced to re-architect or re-build from scratch. Therefore, it has been common practice to prepare for changes so that software products are extensible over their lifetimes. However, making software extensible is challenging because it is difficult to anticipate successive changes and to provide adequate abstraction mechanisms over potential changes. Such extensibility mechanisms, furthermore, should not compromise any existing functionality during extension. Software engineers would benefit from a tool that provides a way to add extensions in a reliable way. It is natural to expect programming languages to serve this role. Extensible programming is one effort to address these issues. In this thesis, we present type safe extensible programming using the MLPolyR language. MLPolyR is an ML-like functional language whose type system provides type-safe extensibility mechanisms at several levels. After presenting the language, we will show how these extensibility mechanisms can be put to good use in the context of product line engineering. Product line engineering is an emerging software engineering paradigm that aims to manage variations, which originate from successive changes in software.

    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.

    We study quantum modifications to cosmology in a Friedmann-Robertson-Walker universe with and without scalar fields by taking the renormalisation group running of gravitational and matter couplings into account. We exploit the Bianchi identity to relate the renormalisation group scale with scale factor and derive the improved cosmological evolution equations. We find two types of cosmological fixed points where the renormalisation group scale either freezes in, or continues to evolve with scale factor. We discuss the implications of each of these, and classify the different cosmological fixed points with and without gravity displaying an asymptotically safe renormalisation group fixed point. We state conditions of existence for an inflating ultraviolet cosmological fixed point for Einstein gravity coupled to a scalar field. We also discuss other fixed point solutions such as 'scaling' solutions, or fixed points with equipartition between kinetic and potential energies.

    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.

    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

    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.

    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.

    2004-01-01

    This statement is intended to inform pediatricians and other health care professionals, parents, superintendents, and school board members about nutritional concerns regarding soft drink consumption in schools. Potential health problems associated with high intake of sweetened drinks are 1) overweight or obesity attributable to additional calories in the diet; 2) displacement of milk consumption, resulting in calcium deficiency with an attendant risk of osteoporosis and fractures; and 3) dental caries and potential enamel erosion. Contracts with school districts for exclusive soft drink rights encourage consumption directly and indirectly. School officials and parents need to become well informed about the health implications of vended drinks in school before making a decision about student access to them. A clearly defined, district-wide policy that restricts the sale of soft drinks will safeguard against health problems as a result of overconsumption.

  15. Aflatoxins and safe storage

    PubMed Central

    Villers, Philippe

    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

  16. Injections--how safe.

    Injection, is a skin-piercing event performed by a syringe and needle with the purpose of introducing a curative substance or vaccine in a patient. According to WHO, safe injection is one which does not harm to the recepient, does not expose the health worker to any risk and does not result in waste that is dangerous for the community. To achieve this injection should be prepared on a clean workspace, provider should clean his hands appropriately, sterility of the syringe and needle to be maintained, skin of the recipient should be cleaned and above all sharps waste should be managed appropriately. Common danger of unsafe injection is infection. Most medication used in primary care can be administered orally. So firstly the behaviour of healthcare providers and patients must be changed so as to decrease overuse of injections, secondly provision of sufficient quantities of appropriate injection equipment and infection control supplies should be made available and thirdly a sharp waste management system should be set up.

  1. 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.

    DOEpatents

    Roesler, Alexander W.; Wooden, Susan M.

    2009-05-12

    Microelectromechanical (MEM) safe-arm devices comprise a substrate upon which a sense mass, that can contain an energetic material, is constrained to move along a pathway defined by a track disposed on the surface of the substrate. The pathway has a first end comprising a "safe" position and a second end comprising an "armed" position, whereat the second end the sense mass can be aligned proximal to energetic materials comprising the explosive train, within an explosive component. The sense mass can be confined in the safe position by a first latch, operable to release the sense mass by an acceleration acting in a direction substantially normal to the surface of the substrate. A second acceleration, acting in a direction substantially parallel to the surface of the substrate, can cause the sense mass to traverse the pathway from the safe position to the armed position.

    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.

    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.

  18. Effect of the distribution system on drinking-water quality

    1993-01-01

    The Safe Drinking Water Act and its Amendments has focused interest on the factors that cause the deterioration of water between the treatment plant and the consumer. The distribution system itself can contribute to this deterioration. Numerous examples of waterborne disease outbreaks have demonstrated the importance of the distribution system in preventing disease. Water-quality propagation models can be used to study the factors that contribute to water quality deterioration. These models have been used in many locations to study contaminant propagation. The paper describes the application of contaminant propagation models in the South Central Connecticut Regional Water Authority (USA). The fluoride feed was cut off at the water treatment plant to calibrate the model and determine residence times in the system. An extensive simulation of the system was conducted to predict conservative contaminant propagation and chlorine decay. After completing the simulation study a sampling program was conducted to verify the results from the model. In general the field results verified the model predictions. Water quality varied widely over the service area. Long retention times in storage tanks and pipe wall demand, especially in dead end sections, caused significant losses in chlorine residuals.

    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.

    A convenient method is described for monitoring Cd, Ni, Cu, and Pb at trace levels in drinking water samples. These metals are preconcentrated on a chelating solid-phase extraction disk and then determined by X-ray fluorescence spectrometry. The method tolerates a wide pH range (pH 6-14) and a large amount of alkaline and alkaline earth elements. The preconcentration factor is well over 1600, assuming a 1 L water sample volume. The limits of detection for Cd, Ni, Cu, and Pb are 3.8, 0.6, 0.4, and 0.3 ng/mL, respectively. These are well below the federal maximum contaminant level values, which are 5, 100, 1300, and 15 ng/mL, respectively. The proposed method has many advantages including ease of operation, multielement capability, nondestructiveness, high sensitivity, and relative cost efficiency. The solid-phase extraction step can be conducted in the field and then the disks can be mailed to a laboratory for the analysis, eliminating the cost of transporting large volumes of water samples. Furthermore, the color of the used extraction disk provides an initial estimate of the degree of contamination for some transition metals (for example, Ni and Cu). Thus, the overall cost for analysis of metals in drinking water can be minimized by implementing the method, and small water supply companies with limited budgets will be better able to comply with the Safe Drinking Water Act.

    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.

    Objective The aim of this study was to assess whether the effect of parenthood on alcohol intake varies according to the context in which the drinking act occurs. Method The data were drawn from the Canadian Addiction Survey, a national telephone survey conducted in 2004. The analytical sample included 1,079 drinking occasions nested in 498 female drinkers and 926 drinking occasions nested in 403 male drinkers between 18 and 55 years of age. A multilevel linear statistical model was used to estimate the variance related to the drinking occasion (Level 1) and to the parental role (Level 2). Results Parenthood was not associated with alcohol intake per occasion. Drinking context variables brought great explanatory power to the study of alcohol intake, but, overall, the effect of parenthood on alcohol intake did not vary according to the context in which drinking occurs. Only one interaction between the parental role and contextual characteristics was found. Conclusions Men's and women's alcohol intake within drinking contexts is more likely to be influenced by the immediate context in which drinking occurs than by their parental role. The explanation for alcohol behaviors within the general Canadian population may lie as much in the situation as in the person. PMID:21388599

    The aim of this survey study was to explore the influence of work on individual's drinking behavior. From October 1994 to March 1995, the present researchers implemented a self-administered questionnaire survey on workers in the manufacturing sector in Metropolitan Kaohsiung area, southern Taiwan. Of the 1,117 subjects selected, 668 (61.8%) stated that they had had one or more drinks during the preceding month. The average daily consumption of alcohol was 0.2 +/- 0.9 drinks (with a range of 0 to 12 drinks and a median of 0.02 drinks). In addition, 188 (28.8%) of the subjects reported having experienced drinking-related problems during the preceding month, and 35 respondents (5.2%) gave escape from job stress as the reason for their drinking in the preceding month. The result of multivariate analyses showed that workers who reported less autonomy in their job were more likely to experience drinking-related problems (odds ratio [OR] = 1.3) and to drinking for psychological relief (OR = 1.2); that workers who reported more demanding job conditions were more likely to drink for escape (OR = 2.5) but had lower levels of drinking (t = -2.5, p = 0.01); and that workers who reported high levels of job strain were more likely to experience drinking-related problems and to drink for relief but had lower levels of drinking. The details and implications of this result will be discussed.

    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.

    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.

    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.

    A substantial portion of the world's population does not have ready access to safe water. Moreover, obtaining water may involve great expense of time and energy for those who have no water sources in or near home. From an historical perspective, with the invention of piped water, fetching water has only recently become largely irrelevant in many locales. In addition, in most instances, wells and clean surface water were so close by that fetching was not considered a problem. However, population growth, weather fluctuations and social upheavals have made the daily chore of carrying water highly problematic and a public health problem of great magnitude for many, especially women, in the poor regions and classes of the world. In this paper, we consider gender differences in water carrying and summarize data about water access and carrying from 44 countries that participated in the Multiple Indicator Cluster Survey (MICS) program. Women and children are the most common water carriers, and they spend considerable time (many trips take more than an hour) supplying water to their households. Time is but one measure of the cost of fetching water; caloric expenditures, particularly during droughts, and other measures that affect health and quality of life must be considered. The full costs of fetching water must be considered when measuring progress toward two Millennium Development Goals--increasing access to safe drinking water and seeking an end to poverty.

    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.

    Toxicological implications due to the use of herbicide-contaminated drinking water, as well as other organic chemicals, are related to their nature and levels. These implications can be defined for each substance on the basis of an adequate evaluation of epidemiological information and experimental data on animals. In this paper, World Health Organization's procedures for establishing guidelines for 11 herbicides widely used in Italy are described. Furthermore, data and information about the use of these herbicides and their levels in Italian drinking-water supplies are also reported and discussed. Finally, factors and conditions responsible for the groundwater contamination by some herbicides in determined areas are presented and discussed.

    Entamoeba histolytica, Giardia lamblia, Cryptosporidium parvum, Isospora belli, Balantidium coli, and Microsporidia spp. are cosmopolitan parasites. They often cause diarrheal diseases. The waterborn transmission of all these parasites is possible (41). Surface water supplies used for drinking water are potential sources of contamination. Giardia lamblia and Cryptosporidium spp. have received great attention in industrialized countries during the last years because they are the etiological agents of waterborne diseases. The life cycles of Giardia lamblia and Cryptosporidium are described with a special reference to drinking water technologies aimed at removing these parasites. PMID:8253478

    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.

    Mindfulness and drinking motives have both been linked to affect regulation, yet the relationship between mindfulness and drinking motives is poorly understood. The present study examined whether drinking motives, particularly mood regulatory motives, mediated the associations between facets of mindfulness and alcohol-related outcomes among college students (N = 297). We found 3 specific facets of mindfulness (describing, nonjudging of inner experience, and acting with awareness) to have negative associations with alcohol outcomes. Importantly, specific drinking motives mediated these associations such that lower levels of mindfulness were associated with drinking for distinct reasons (enhancement, coping, conformity), which in turn predicted alcohol use and/or alcohol problems. Our findings suggest that drinking motives, especially mood regulatory and negative reinforcement motives, are important to examine when studying the role of mindfulness in college student drinking behavior.

    Pedersen, W

    1990-11-01

    In a study of 1230 Norwegian adolescents aged 14-19, the prevalence of participation in 'drinking games' and the consequences thereof were investigated. The findings indicate that drinking games are very common among Norwegian youth. Further, there is a substantially higher alcohol consumption among those who participate in these games than among other youth, even when we 'control' for other indicators of network 'wetness'. In particular, a high consumption of beer among the boys seems to be connected with these games. It seems reasonable to assume that the drinking games are of importance for many young people, in particular as a means of being accepted by social groups of the same age. The games provide an organized, yet exciting frame around the interaction. It seems reasonable to assume that the participants usually take part in the games as a result of an intention to drink. Even so, it might be argued that the games are probably often more than 'neutral tools' to fulfil this intention: first of all, the games involve intense contact precisely in connection with alcohol consumption. Secondly, we know from previous studies that match rates and role modelling in connection with consumption increase with an increase in the intensity of group member contact. Finally, the individual member loses control and steering of his/her own consumption to a large extent: consumption becomes to a large degree a function of other people's actions and the rules of the game in question.

    Tourniquets are often needed for optimized phalangeal surgeries. However, few surgeons forget to remove them and caused ischemic injuries. We have a modified method to create a safe finger tourniquet for short duration finger surgeries, which can avoid such tragedy. It is done by donning a glove, cutting the tip of the glove over the finger of interest, and rolling the glove finger to the base. From 2010 to 2013, approximately 54 patients underwent digital surgical procedures with our safe finger tourniquet. Because the glove cannot be forgotten to be removed, the tourniquet must be released and removed. This is a simple and efficient way to apply a safe finger tourniquet by using hand rubber glove for a short-term bloodless finger surgery and can achieve an excellent surgical result.

  2. Addressing barriers to safe abortion.

    2013-05-01

    The latest World Health Organization data estimate that the total number of unsafe abortions globally has increased to 21.6 million in 2008. There is increasing recognition by the international community of the importance of the contribution of unsafe abortion to maternal mortality. However, the barriers to delivery of safe abortion services are many. In 68 countries, home to 26% of the world's population, abortion is prohibited altogether or only permitted to save a woman's life. Even in countries with more liberal abortion legal frameworks, additional social, economic, and health systems barriers and the stigma surrounding abortion prevent adequate access to safe abortion services and postabortion care. While much has been achieved to reduce the barriers to comprehensive abortion care, much remains to be done. Only through the concerted action of public, private, and civil society partners can we ensure that women have access to services that are safe, affordable, confidential, and stigma free.

    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

    To clarify reasons for drinking in relation to problem drinking behavior, 494 male students, aged 15 to 18 years old and attending high schools in Tokyo, Japan, were examined by self-rating questionnaires including the Kuriharna Alcoholism Screening Test (KAST). Three hundred and forty-two students (69%) completed the questionnaires, of whom 143 indicated that they were current drinkers of alcohol (42% of respondents). Of the 143,16 (11%) reported, through the KAST, experience of problem drinking behavior. A factor analysis of 36 reasons for drinking identified 5 factors: Escapism, Sociability, Tension Reduction, Acting Like a Man, and Enjoyment/Home. A logistic regression analysis showed that drinking because of Escapism, Sociability, and Tension Reduction was significantly related to problem drinking behavior. Also, there was significant correlation between the 3 factors and the number of KAST items experienced by the 143 respondents. Our findings suggest that the factors of Escapism, Sociability, and Tension Reduction lead to problem drinking in Japanese high school students.

    Background. State-level ‘age 21’ drinking laws conform generally with the United States National Minimum Drinking Age Act of 1984 (US), and are thought to protect young people from adverse drinking experiences such as heavy episodic drinking (HED, sometimes called ‘binge drinking’). We shed light on this hypothesis while estimating the age-specific risk of transitioning from 1st full drink to 1st HED among 12-to-23-year-old newly incident drinkers, with challenge to a “gender gap” hypothesis and male excess described in HED prevalence reports. Methods. The study population consisted of non-institutionalized civilians in the United States, with nine independently drawn nationally representative samples of more than 40,000 12-to-23-year-olds (2006–2014). Standardized audio computer-assisted self-interviews identified 43,000 newly incident drinkers (all with 1st HED evaluated within 12 months of drinking onset). Estimated age-specific HED risk soon after first full drink is evaluated for males and females. Results. Among 12-to-23-year-old newly incident drinkers, an estimated 20–30% of females and 35–45% of males experienced their 1st HED within 12 months after drinking onset. Before mid-adolescence, there is no male excess in such HED risk. Those who postponed drinking to age 21 are not spared (27% for ‘postponer’ females; 95% CI [24–30]; 42% for ‘postponer’ males; 95% CI [38–45]). An estimated 10–18% females and 10–28% males experienced their 1st HED in the same month of their 1st drink; peak HED risk estimates are 18% for ‘postponer’ females (95% CI [15–21]) and 28% for ‘postponer’ males (95% CI [24–31]). Conclusions. In the US, one in three young new drinkers transition into HED within 12 months after first drink. Those who postpone the 1st full drink until age 21 are not protected. Furthermore, ‘postponers’ have substantial risk for very rapid transition to HED. A male excess in this transition to HED is not

  13. Unintended consequences of regulating drinking water in rural Canadian communities: examples from Atlantic Canada.

    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.

    Water soluble compounds persistent in humans and the environment pose a challenge for estimating safe levels in tap water. A viable approach to estimate a drinking water equivalent level (DWEL) for perfluorooctanoic acid (PFOA) was applied to its extensive relevant information from human and laboratory animal studies. PFOA has been identified at 3.5 microg/L (mean) in tap water in proximity to a manufacturing facility; however, in most supplies, the levels were below 7.5 ng/L (usual limit of detection). PFOA has an average half-life in humans of 3.5years. From animal studies, PFOA is considered a possible hepatotoxicant and developmental toxicant for humans. Based on two chronic studies, PFOA was judged to be a possible human carcinogen, whose mode-of-action was likely to be related to receptor activation but not genotoxicity. The Benchmark Dose-Uncertainty Factor approach was selected for dose-response for noncancer and cancer. Based on internal dose of PFOA, the DWEL protective against cancer is 7.7 microgPFOA/L tap water, and the noncancer DWELs range from 0.88 to 2.4 microg/L. These DWELs can be considered a reliable, albeit conservative, basis to set a Maximum Concentration Level Goal under the US Safe Drinking Water Act. PMID:19631249

    Several serotonin uptake inhibitors, including the long-acting fluoxetine, have been found to decrease alcohol intake in moderately dependent alcoholics. While the mechanism of their effect is not fully elucidated, a previous study with citalopram indicated that decreased desire to drink may be an important factor. Therefore, we tested fluoxetine effects on alcohol intake and desire to drink in a placebo-controlled study. Subjects, recruited by advertisement, were mildly/moderately dependent alcoholics (12 male, four female, aged 19-59 years, healthy, non-depressed) who did not believe they had a drinking problem and were not requesting treatment. After a 1 week baseline they received, single-blind, 2 weeks placebo followed by 2 weeks fluoxetine 60 mg/day. As out-patients, subjects recorded daily standard drinks (13.6 g ethanol) and rated interest, desire, craving and liking for alcohol biweekly. Each out-patient period was immediately followed by a double-blind experimental drinking session. Out-patient daily drinks slightly decreased during fluoxetine to 6.6 +/- 0.9 (mean +/- S.E.M.) compared with during placebo (7.16 +/- 0.95, p = 0.07, N.S.) and baseline (7.18 +/- 1.0, p > 0.1, N.S.). Desire, interest and craving for alcohol decreased during fluoxetine vs placebo baseline (p < 0.05), but not vs placebo. Appetite loss and decrease in food intake (p < 0.01, fluoxetine vs placebo) correlated with each other (r = 0.91, p < 0.01) but neither correlated with decrease in alcohol intake (appetite: r = 0.26, N.S.; food intake: r = 0.22, N.S.). Weight loss occurred during fluoxetine (p < 0.05 vs placebo) but did not correlate with decrease in alcohol intake (r = 0.1, N.S.). In the experimental drinking sessions after placebo and fluoxetine treatments subjects rated their desire for each of 18 mini-drinks (each one-third of a standard drink) offered at 5 min intervals. Fluoxetine decreased desire to drink throughout the sessions; both mean and maximum desire ratings were

    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.

    2016-01-01

    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.

    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.

    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

    2010-08-01

    The aim of the current study was to initiate and describe the development of a Simulated Drinking Game Procedure (SDGP), a safe, efficient, and alcohol-free laboratory protocol for studying drinking game behavior. Fifty-two undergraduates completed the SDGP in a laboratory session, where participants played singles and/or doubles games of Beer Pong. Water was substituted for alcohol in all of the games. The number of drinks consumed during matches and 20-min play periods were coded during each session, and software was used to estimate the peak blood alcohol concentration (BAC) a participant would achieve if he or she had consumed actual alcohol while participating in the SDGP. Results indicated that participation in Beer Pong can lead to rapid consumption of alcohol and an associated rise in BAC. Results also highlight additional risks for female participants associated with participation in drinking games. The SDGP is a research tool capable of increasing our understanding of drinking games.

    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.

    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

    Complications of induced abortion sadly remain significant causes of maternal mortality and morbidity around the world, but only in countries that do not provide access to safe abortion services. This article presents a brief account of how high maternal mortality from induced abortion became history in the UK and the dire consequences to women's health that unsafe abortion still has in many countries of the world. It gives a brief overview of the methods available to evacuate the uterus, with particular reference to manual vacuum aspiration. The status of the law in different countries is discussed, together with the need for health professionals to interpret repressive laws in ways that enables them to care for women who seek their help. Safe abortion services are cost effective, essential services for women. Men are part and parcel of the reason women resort to terminating a pregnancy, and, together with the countless children whose lives are dependent on a healthy caring mother, are also beneficiaries of safe abortion services. There can be no excuse for continuing to deny these services to so many women around the world.

    Although it are quite well known the possible effects of climate changes on surface waters availability and their hydrological risks, their consequences on drinking water quality is not well defined yet. Disinfection agents (as Cl2, O3, etc.) or multiple combinations of them for water treatment and disinfection purposes are applied by water treatment plants at worldwide level. Unfortunately, besides the benefits of these processes were also highlighted some undesirable effects such as formation of several disinfection by-products (DBPs) after reaction of disinfection agent with natural organic matter (NOM) from water body. DBPs formation in drinking water, suspected to posses adverse health effects to humans are strongly regulated in our days. Thus, throughout this study kinetics experiments both the main physicochemical factors that influencing the quality of drinking waters were evaluated as well how they act through possible warming or the consequences of extreme events. Increasing water temperatures with 1 - 5 °C above its normal value has showed that NOMs are presented in higher amount which led to the need for greater amount of disinfectant agent (5 - 15 %). Increasing the amount of disinfecting agent resulted in the formation of DBPs in significantly higher concentrations (between 5 - 30 %).

    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.

    Land use in geographic areas that replenish groundwater and surface water resources is increasingly recognized as an important factor affecting drinking water quality. Efforts to understand the implications for health, particularly outcomes with long latency or critical exposure windows, have been hampered by lack of historical exposure data for unregulated pollutants. This limitation has hindered studies of the possible links between breast cancer risk and drinking water impacted by endocrine disrupting compounds and mammary carcinogens, for example. This paper describes a methodology to assess potential historical exposure to a broad range of chemicals associated with wastewater and land use impacts to 132 groundwater wells and one surface water body supplying drinking water to 18 public distribution systems on Cape Cod, MA. We calculated annual measures of impact to each distribution system and used the measures as exposure estimates for the residential addresses of control women in the Cape Cod Breast Cancer and Environment Study (Cape Cod Study). Impact was assessed using (1) historical chemical measurements of nitrate at the water supply sources (performed as required by the Safe Water Drinking Act) and (2) a geographic information system analysis of land use within the zones of contribution (ZOCs) delineated for each well in a state-mandated wellhead protection program. The period for which these impact estimates were developed (1972-1995) was constrained by the availability of chemical measurements and land use data and consideration of time required for groundwater transport of contaminants to the water supply wells. Trends in these estimates for Cape Cod suggest increasing impact to drinking water quality for land use over the study period. Sensitivity analyses were conducted to assess the effect on the distribution of controls' cumulative exposure estimates from (1) reducing the area of the ZOCs to reflect typical well operating conditions rather than
