    The U.S. Geological Survey South Atlantic Water Science Center collected borehole geophysical logs and images and continuous water-level data near the GMH Electronics National Priorities List Superfund site near Roxboro, North Carolina, during December 2012 through July 2015. Previous work by the U.S. Geological Survey South Atlantic Water Science Center at the site involved the collection of borehole geophysical log data in 15 wells, in addition to surface geologic mapping and passive diffusion bag sampling. In a continued effort to assist the U.S. Environmental Protection Agency in developing a conceptual groundwater model to assess current contaminant distribution and future migration of contaminants, more than 900 subsurface features (primarily fracture orientations) in 10 open borehole wells were delineated and continuous water-level data information from 14 monitoring wells within close proximity of the initially drilled boreholes was collected to observe any induced water-level fluctuations during drilling operations

    Siegel, M.R.; Friedman, J.R.; Neff, R.W.

    1993-03-01

    As part of an ongoing effort to reform and restructure the US Environmental Protection Agency`s (EPAS) Superfund program, the EPA Administrator on October 21, 1991, announced several key programmatic reforms. These reforms are a result of the Superfund 30-Day Task Force Report (30-Day Study, EPA 1991a), an effort carried out by EPAs office of Solid Waste and Emergency Response (OSWER). The EPA OSWER oversees environmental cleanup activities under a number of statutory authorities, including the Comprehensive Environmental response, Compensation, and Liability Act (CERCLA, also known as Superfund). CERCLA and its implementing regulation, the National Contingency Plan (NCP), establish a regulatory framework to govern the cleanup of existing, and often abandoned, hazardous waste sites. The purposes of this report are to (1) review the background and recommendations of EPNs 30-Day Study, (2) identify and discuss the initiatives from the 30-Day Study that may impact DOE`s environmental restoration mission, (3) report on EPAs progress in implementing the selected priority initiatives, and (4) describe potentially related DOE activities.

  9. Radioactive Water Treatment at a United States Environmental Protection Agency Superfund Site - 12322

    SciTech Connect

    Beckman, John C.

    2012-07-01

    A water treatment system at a United States Environmental Protection Agency (USEPA) Superfund site impacted by radiological contaminants is used to treat water entering the site. The United States Army Corps of Engineers (USACE) is actively managing the remedial action for the USEPA using contracts to support the multiple activities on site. The site is where former gas mantle production facilities operated around the turn of the century. The manufacturing facilities used thorium ores to develop the mantles and disposed of off-specification mantles and ore residuals in the surrounding areas. During Site remedial actions, both groundwater and surface water comes into contact with contaminated soils and must be collected and treated at an on-site treatment facility. The radionuclides thorium and radium with associated progeny are the main concern for treatment. Suspended solids, volatile organic compounds, and select metals are also monitored during water treatment. The water treatment process begins were water is pumped to a collection tank where debris and grit settle out. Stored water is pumped to a coagulant tank containing poly-aluminum chloride to collect dissolved solids. The water passes into a reaction tube where aspirated air is added or reagent added to remove Volatile Organic Compounds (VOC'S) by mass transfer and convert dissolved iron to a solid. The water enters the flocculent polymer tank to drop solids out. The flocculated water overflows to a fluidized bed contact chamber to increase precipitation. Flocculation is where colloids of material drop out of suspension and settle. The settled solids are periodically removed and disposed of as radioactive waste. The water is passed through filters and an ion exchange process to extract the radionuclides. Several million liters of water are processed each year from two water treatment plants servicing different areas of the remediation site. Ion exchange resin and filter material are periodically replaced

    While many readers of the Federal Facilities Environmental Journal are involved with the performance of Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) cleanup on Department of Defense and Department of Energy facilities, many may be unfamiliar with the much broader CERCLA liability of federal agencies under other circumstances. This article places the various kinds of federal agency CERCLA liability into that wider context and serves as a lessons learned for environmental managers who want to avoid creating new CERCLA liability for their agencies.

  14. Reinventing Superfund means de-inventing'' superfund

    SciTech Connect

    McFarland, C.J. )

    1994-03-01

    The White House claims there are some things the federal government does that it could do better and other things it should not do at all. It is in this light that the federal government should delegate responsibility for Superfund to the states. Various factors that drove the federalization of many environmental programs in the 1970s and 1980s no longer apply for Superfund. Air and water pollution programs were federalized partly because states feared businesses would relocate to friendlier'', less environmentally stringent areas. States would not impose sufficiently stringent environmental controls, because pursuing tougher standards meant committing economic suicide. Thus, uniform air and water pollution standards were implemented on a federal level to eliminate business flight. Superfund, by contrast, imposes costs based wholly on past activities. One state's determination to rededicate its waste sites quickly and more stringently than another state has little effect on a business's location decisions. Relocating a plant does not change where the waste previously was disposed.

    1995-12-31

    In the Spring of 1995, The National Institute of Environmental Health Sciences (NIEHS) sponsored a two-day Symposium on ``Transfer of Basic (Superfund) Research to Waste Site Remediation`` in collaboration with the Department of Defense`s (DOD) Environmental Education Demonstration Grant Program, the US Environmental Protection Agency (USEPA), the California Environmental Protection Agency (Cal EPA) and the Lawrence Berkeley and Livermore National Laboratories (LBL and LLNL). The Symposium`s purpose was three-fold: (1) to familiarize DOD environmental managers with the multi-disciplinary research approach of the NIEHS Superfund Basic Research Program; (2) to exchange information on DOD research priorities and (3) to identify issues with and recommend remedies for converting technological advances from the laboratory to actual practice. The purpose of this paper is to provide a brief description of the NIEHS Superfund Basic Research Program (SBRP) and to summarize selected discussions and issues identified regarding technology transfer.

  13. Results of a monitoring program of continuous water levels and physical water properties at the Operable Unit 1 area of the Savage Municipal Well Superfund site, Milford, New Hampshire, water years 2000-03

    USGS Publications Warehouse

    Harte, Philip T.

    2005-01-01

    The Milford-Souhegan glacial-drift (MSGD) aquifer, in south-central New Hampshire, is an important source of industrial, commercial, and domestic water. The MSGD aquifer was also an important source of drinking water for the town of Milford until it was found to contain high concentrations of volatile organic compounds (VOCs) in the Savage and Keyes municipal-supply wells in the early 1980s. A VOC plume was found to cover part of the southwestern half of the MSGD aquifer. In September 1984, the site was designated a Superfund site, called the Savage Municipal Well Superfund site. The primary source area of contaminants was a former tool manufacturing facility (called the OK Tool facility, and now called the Operable Unit 1 (OU1) area) that disposed of solvents at the surface and in the subsurface. The facility was closed in 1987 and removed in 1998. A low-permeability containment barrier wall was constructed and installed in the overburden (MSGD aquifer) in 1998 to encapsulate the highest concentrations of VOCs, and a pump-and-treat remediation facility was also added. Remedial operations of extraction and injection wells started in May 1999. A network of water-level monitoring sites was implemented in water year 2000 (October 1, 1999, through September 30, 2000) in the OU1 area to help assess the effectiveness of remedial operations to mitigate the VOC plume, and to evaluate the effect of the barrier wall and remedial operations on the hydraulic connections across the barrier and between the overburden and underlying bedrock. Remedial extraction and injections wells inside and outside the barrier help isolate ground-water flow inside the barrier and the further spreading of VOCs. This report summarizes both continuous and selected periodic manual measurements of water level and physical water properties (specific conductance and water temperature) for 10 monitoring locations during water years 2000-03. Additional periodic manual measurements of water levels were

  14. Revisions to US EPA Superfund Risk and Dose Assessment Models and Guidance - 13403

    2013-07-01

    The U.S. Environmental Protection Agency (EPA) Superfund program's six Preliminary Remediation Goal (PRG) and Dose Compliance Concentration (DCC) internet based calculators for risk and dose assessment at Superfund sites are being revised to reflect better science, revisions to existing exposure scenarios and new scenarios, and changes to match up more closely with the EPA chemical regional screening level calculator. A revised version of the 1999 guidance document that provides an overview for the Superfund risk assessment process at radioactively contaminated sites, 'Radiation Risk Assessment At CERCLA Sites: Q and A', is being completed that will reflect Superfund recommended guidance and other technical documents issued over the past 13 years. EPA is also issuing a series of fact sheets in the document 'Superfund Radiation Risk Assessment: A Community Tool-kit'. This presentation would go over those changes that are expected to be finished by this spring. (authors)

  15. Identifying the extent of a Superfund site

    SciTech Connect

    Gowland, P.A.; Chantry, W.; Wisniewski, R.

    1995-12-31

    There has been considerable misunderstanding regarding the extent of private and Federal facility sites listed under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or Superfund program. This problem, which occurs primarily at the time of proposal or finalization of a site to the National Priorities List (NPL), seems to be due both to semantics and errors in perception. The term ``site`` has been used differently in performing CERCLA removal and remediation activities, in the installation restoration programs of various Federal agencies, and by the public when preparing comments on proposed NPL sites. It has been confused with the terms source, solid waste management unit, and facility. The most common interpretation by the public of the term ``site`` and its extent is that the site encompasses the property owned by the facility named in the NPL designation or at which a removal has occurred. However, based on the related definitions in CERCLA, a site is best defined as the location of a release (or releases) of hazardous substances and wherever the hazardous substances have come to be located. The extent of a site neither is limited by property boundaries, nor does it include clean areas within a facility`s boundaries. This paper will identify the basis for the Environmental Protection Agency`s (EPA`s) definition of site for Superfund purposes, including aggregated sites, relevant court decisions and statements of EPA policy, and provide case histories of how this definition has been applied at both private and Federal facilities.

  16. Partnering at Superfund sites -- a win-win situation

    SciTech Connect

    Neumann, M.G.; Ohlinger, B.

    1994-12-31

    Combining today`s litigious society with shrinking profit margins for Superfund contractors results in adversarial relationships among all parties involved in Superfund site remediation, such as regulatory agencies, designers, contractors, suppliers and owners. These negative relationships have a detrimental effect on the project at hand. Partnering is an available solution to the problem and creates a win-win situation for everyone. This presentation defines partnering, describes the process and gives real-world examples from two Superfund Sites, citing successes and giving tips on how to make partnering work for you. Partnering is working at the Bofors-Nobel Superfund Site in Muskegon, Michigan. Located six miles east of downtown Muskegon, the 85-acre Bofors site includes an active chemical production facility, an unused landfill, and abandoned sludge lagoons. Used for chemical manufacturing since the early 1960s, soil and groundwater at Bofors-Nobel are contaminated with pesticides, dye intermediates, aromatic hydrocarbons, and chlorinated organic compounds. Within 13 miles of the Bofors site is the Ott/Story/Cordova Superfund site. The 1.35 mgd groundwater treatment facility under construction there will surpass the capacity of the Bofors plant by nearly a quarter-million gallons per day. The 20-acre Ott/Story/Cordova site sits on more than 1 billion gallons of groundwater contaminated with chlorides, phenols, volatile organic compounds, and heavy metals which have percolated through the sandy soil of wastewater lagoons.

    Currie, Janet; Greenstone, Michael; Moretti, Enrico

    2011-05-01

    We are the first to examine the effect of Superfund cleanups on infant health rather than focusing on proximity to a site. We study singleton births to mothers residing within 5km of a Superfund site between 1989-2003 in five large states. Our "difference in differences" approach compares birth outcomes before and after a site clean-up for mothers who live within 2,000 meters of the site and those who live between 2,000- 5,000 meters of a site. We find that proximity to a Superfund site before cleanup is associated with a 20 to 25% increase in the risk of congenital anomalies.

    Spengler, Robert F; Anderson, Beth E; Zenick, Harold

    2002-03-01

    Numerous studies have shown that the release of hazardous substances in the environment impact the environment and human health. Communities want to know if they have been exposed, if their health is affected, and how they can protect themselves. For environmental impacts the concerns include how best to clean up and manage the contamination, and protect the environment. The answers to these questions are complex and many times unknown. Three federal agencies conduct Superfund-related research to answer a wide range of questions from identifying contaminants of concern and health risks to determining effective cleanup and prevention strategies. This article discusses the research programs for the Agency for Toxic Substances and Disease Registry, U.S. Environmental Protection Agency (Office of Research and Development), and National Institute of Environmental Health Sciences (Superfund Basic Research Program). The three agencies collaborate on their research programs and research agenda setting activities. This introduction to Superfund-related research provides a foundation and context for the scientific articles in this special edition of the journal. Because of the magnitude of environmental and human health concerns, there is a critical need for additional research to address many challenging questions involving exposures, biological responses, and environmental technologies.

  14. Defending Superfund and RCRA imminent hazard cases

    Miller, J.G.

    1983-01-01

    Legal defenses by the government under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (Superfund) and the Resource Conservation and Recovery Act include common defenses in which there is (1) no imminent or substantial endangerment, (2) inappropriate remedy, (3) action not in accord with the National Contingency Plan that governs Environmental Protection Agency (EPA) remedial actions, (4) not credible or sufficient evidence, (5) not credible scientific conclusion, or (6) government action precluding the relief. Defenses to Superfund reimbursement claims include cases (1) when defendant is not among the class of liable partners, (2) of joint and several liability and the right of contribution, (3) involving releases by an act of God, war, or third party. Defenses to abatement actions include cases in which (1) there is no irreparable harm and adequate remedy at law is available and (2) emergency provisions are not retrospective. Also relevant to EPA enforcement efforts are political pressures and the government's intentions. The author discusses basic defense strategies and implementation tactics. 67 references.

    This Record of Decision (ROD) documents the U.S. Environmental Protection Agency`s (EPA`s) selection of the remedial action for the Anchor Chemical Superfund Site (the `Site`). EPA, in consultation with the State of New York, has determined that the Achor Chemical Superfund Site does not pose a significant threat to human health or the environment and, therefore, further remediation is not appropriate. This determination is based on the findings of the Remedial Investigation and the baseline Risk Assessment. The risks posed by the Site are within EPA`s acceptable risk range and therefore do not pose a threat to human health or the environment.

  17. Sense of agency in continuous action: Assistance-induced performance improvement is self-attributed even with knowledge of assistance.

    PubMed

    Inoue, Kazuya; Takeda, Yuji; Kimura, Motohiro

    2017-02-01

    In a task involving continuous action to achieve a goal, the sense of agency increases with an improvement in task performance that is induced by unnoticed computer assistance. This study investigated how explicit instruction about the existence of computer assistance affects the increase of sense of agency that accompanies performance improvement. Participants performed a continuous action task in which they controlled the direction of motion of a dot to a goal by pressing keys. When instructions indicated the absence of assistance, the sense of agency increased with performance improvement induced by computer assistance, replicating previous findings. Interestingly, this increase of sense of agency was also observed even when instructions indicated the presence of assistance. These results suggest that even when a plausible cause of performance improvement other than one's own action exists, the improvement can be misattributed to one's own control of action, resulting in an increased sense of agency.

    The National Institute of Environmental Health Sciences (NIEHS) Superfund Basic Research and Training Program (SBRP) was established in 1986 by the Superfund Amendments and Reauthorization Act (SARA). This is a unique program of basic research and training grants directed towards understanding, assessing and attenuating the adverse effects on human health resulting from exposure to hazardous substances. The research findings from this program are being used by state, local, and federal agencies, private organizations and industry in making decisions related to the management of hazardous substances. Many innovative technologies for detecting, assessing and reducing toxic materials in the environment have been developed as a result of funding by the SBRP. To assist grantees, the SBRP has developed a technology transfer strategy designed to handle the unique problems associated with transferring multidisciplinary technology from basic research to applied research.

  10. Evaluating public participation in environmental decision-making: EPA's superfund community involvement program.

    PubMed

    Charnley, Susan; Engelbert, Bruce

    2005-11-01

    This article discusses an 8-year, ongoing project that evaluates the Environmental Protection Agency's Superfund community involvement program. The project originated as a response to the Government Performance and Results Act, which requires federal agencies to articulate program goals, and evaluate and report their progress in meeting those goals. The evaluation project assesses how effective the Superfund community involvement program is in promoting public participation in decisions about how to clean up hazardous wastes at Superfund sites. We do three things in the article: (1) share our experience with evaluating an Agency public participation program, including lessons learned about methods of evaluation; (2) report evaluation results; and (3) address a number of issues pertaining to the evaluation of public participation in environmental decision-making. Our goal is to encourage more environmental managers to incorporate evaluation into their public participation programs as a tool for improving them. We found that written mail surveys were an effective and economical tool for obtaining feedback on EPA's community involvement program at Superfund sites. The evaluation focused on four criteria: citizen satisfaction with EPA information about the Superfund site, citizen understanding of environmental and human health risks associated with the site, citizen satisfaction with opportunities provided by EPA for community input, and citizen satisfaction with EPA's response to community input. While the evaluation results were mixed, in general, community members who were most informed about and involved in the cleanup process at Superfund sites generally were also the most satisfied with the community involvement process, and the job that EPA was doing cleaning up the site. We conclude that systematic evaluation provides meaningful and useful information that agencies can use to improve their public participation programs. However, there need to be

    Carey, Pat; Walker, Stuart

    2008-01-15

    This paper describes the Superfund program's statutory requirements for community involvement. It also discusses the efforts the Superfund program has made that go beyond these statutory requirements to involve communities. The Environmental Protection Agency (EPA) implements the Superfund program under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA). From the beginning of the Superfund program, Congress envisioned a role for communities. This role has evolved and expanded during the implementation of the Superfund program. Initially, the CERCLA statute had community involvement requirements designed to inform surrounding communities of the work being done at a site. CERCLA's provisions required 1) development of a community relations plan for each site, 2) establishment of information repositories near each site where all publicly available materials related to the site would be accessible for public inspection, 3) opportunities for the public to comment on the proposed remedy for each site and 4) development of a responsiveness summary responding to all significant comments received on the proposed remedy. In recognition of the need for people living near Superfund sites to be well-informed and involved with decisions concerning sites in their communities, SARA expanded Superfund's community involvement activities in 1986. SARA provided the authority to award Technical Assistance Grants (TAGs) to local communities enabling them to hire independent technical advisors to assist them in understanding technical issues and data about the site. The Superfund Community Involvement Program has sought to effectively implement the statutory community involvement requirements, and to go beyond those requirements to find meaningful ways to involve citizens in the cleanup of sites in their communities. We've structured our program around

  1. Spatial disparity in the distribution of superfund sites in South Carolina: an ecological study

    2013-01-01

    Background According to the US Environmental Protection Agency (EPA), Superfund is a federal government program implemented to clean up uncontrolled hazardous waste sites. Twenty-six sites in South Carolina (SC) have been included on the National Priorities List (NPL), which has serious human health and environmental implications. The purpose of this study was to assess spatial disparities in the distribution of Superfund sites in SC. Methods The 2000 US census tract and block level data were used to generate population characteristics, which included race/ethnicity, socioeconomic status (SES), education, home ownership, and home built before 1950. Geographic Information Systems (GIS) were used to map Superfund facilities and develop choropleth maps based on the aforementioned sociodemographic variables. Spatial methods, including mean and median distance analysis, buffer analysis, and spatial approximation were employed to characterize burden disparities. Regression analysis was performed to assess the relationship between the number of Superfund facilities and population characteristics. Results Spatial coincidence results showed that of the 29.5% of Blacks living in SC, 55.9% live in Superfund host census tracts. Among all populations in SC living below poverty (14.2%), 57.2% were located in Superfund host census tracts. Buffer analyses results (0.5mi, 1.0mi, 5.0mi, 0.5km, 1.0km, and 5.0km) showed a higher percentage of Whites compared to Blacks hosting a Superfund facility. Conversely, a slightly higher percentage of Blacks hosted (30.2%) a Superfund facility than those not hosting (28.8%) while their White counterparts had more equivalent values (66.7% and 67.8%, respectively). Regression analyses in the reduced model (Adj. R2 = 0.038) only explained a small percentage of the variance. In addition, the mean distance for percent of Blacks in the 90th percentile for Superfund facilities was 0.48mi. Conclusion Burden disparities exist in the distribution of

    The Superfund Public Information System (SPIS) on CD-ROM contains Superfund data for the United States Environmental Protection Agency. The Superfund data is a collection of four databases, CERCLIS, Archive (NFRAP), RODS, and NPL Sites. Descriptions of these databases and CD contents are listed below. The FolioViews browse and retrieval engine is used as a graphical interface to the data. Users can access simple queries and can do complex searching on key words or fields. In addition, context sensitive help, a Superfund process overview, and an integrated data dictionary are available. RODS is the Records Of Decision System. RODS is used to track site clean-ups under the Superfund program to justify the type of treatment chosen at each site. RODS contains information on technology justification, site history, community participation, enforcement activities, site characteristics, scope and role of response action, and remedy. Explanation of Significant Differences (ESDs) are also available on the CD. CERCLIS is the Comprehensive Environmental Response, Compensation, and Liability Information System. It is the official repository for all Superfund site and incident data. It contains comprehensive information on hazardous waste sites, site inspections, preliminary assessments, and remedial status. The system is sponsored by the EPA`s Office of Emergency and Remedial Response, Information Management Center. Archive (NFRAP) consists of hazardous waste sites that have no further remedial action planned; only basic identifying information is provided for archive sites. The sites found in the Archive database were originally in the CERCLIS database, but were removed beginning in the fall of 1995. NPL sites (available online) are fact sheets that describe the location and history of Superfund sites. Included are descriptions of the most recent activities and past actions at the sites that have contributed to the contamination. Population estimates, land usages, and nearby

    This paper describes the role of the Monsanto Chemical Company in the cleanup of a Superfund site in Galveston, Texas. Although other companies had sent waste to the site over an extended period of time, Monsanto was charged with the entire cost. Monsanto responded by identifying other site users and determining the extent of their liability through chemical analysis of the wastes. They took the lead in organizing the other users and developing an effective cleanup process at a cost much less than the EPA's estimates. They also helped to improve industry's relations with the community.

    The All Indian Pueblo Council (AIPC) through the Pueblo Office of Environmental Protection (POEP) implements and provides a variety of environmental programs and services to the 19 Indian Pueblos of New Mexico. Specifically, the POEP Superfund Program investigates and evaluates potential hazardous waste sites within Pueblo lands. The POEP Superfund Program began in September 1991 when the 19 Pueblo Governors signed a Superfund Memorandum of Agreement with the US Environmental Protection Agency (EPA) Region 6. The goal of the POEP Superfund Program is to determine those sites that are eligible for Superfund-financed remedial action by placing those sites on the National Priorities List (NPL), while including the Pueblo perspective. Because the 19 Pueblos are each unique, sovereign nations, several differences and gaps associated with the current Superfund law and EPA methodologies exist. Currently, the Superfund Hazard Ranking System (HRS) model does not account for Indian religious and ceremonial impacts from these sites. Due to their importance in Pueblo life, culturally significant plants, animals, ceremonial surface water use, and sacred areas should be considered as critical impacts when evaluating the various pathways of exposure of the HRS. Tribal environmental equality is an aspect that will be included into all environmental laws. AIPC and POEP are working to address this issue under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA).

    The Superfund Chemical Data Matrix (SCDM) is a source for factor values and benchmark values applied when evaluating potential National Priorities List (NPL) sites using the Hazard Ranking System. The HRS assigns factor values for toxicity, gas migration potential, gas and ground water mobility, surface water persistence, and bioaccumulation potential based on the physical, chemical, and radiological properties of hazardous substances present at a site. Hazardous substances, as defined for HRS purposes, are CERCLA hazardous substances plus CERCLA pollutants and contaminants. The HRS also assigns extra weight to targets with exposure levels to hazardous substances that are at or above benchmarks. These benchmarks include both risk-based screening concentrations and concentrations specified in regulatory limits for the hazardous substances present at a site for a particular migration pathway.

    The National Oil and Hazardous Substances Pollution Contingency Plan (``NCP``), codified at 40 C.F.R. pt. 300, was first promulgated by the US EPA on July 16, 1982 (the ``1982 NCP``). Required by section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, or CERCLA, and by section 311 of the Clean Water Act (CWA), the NCP ``establish[es] procedures and standards for responding to releases of hazardous substances`` at Superfund sites. The purpose of the NCP ``is to give some consistency and cohesiveness to response planning and actions``. The primary goal of the NCP is to mitigate damage to the environment and protect the public health at the least possible expense. Within this framework, the NCP allows for the evaluation and clean-up activities at a Superfund site to be led directly by the US EPA, the designated state regulatory agency or, under monitoring, by private parties who are potentially responsible for the site contamination. This paper addresses NCP consistency review from both a technical and legal standpoint. The authors will first address the regulatory standards and process for evaluating private party NCP compliance, and then review common legal attacks on NCP compliance that bar the recovery of clean-up costs.

  16. U.S. EPA Superfund Program's Policy for Risk and Dose Assessment

    SciTech Connect

    Walker, Stuart

    2008-01-15

    The Environmental Protection Agency (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) has primary responsibility for implementing the long-term (non-emergency) portion of a key U.S. law regulating cleanup: the Comprehensive Environmental Response, Compensation and Liability Act, CERCLA, nicknamed 'Superfund'. The purpose of the Superfund program is to protect human health and the environment over the long term from releases or potential releases of hazardous substances from abandoned or uncontrolled hazardous waste sites. The focus of this paper is on risk and dose assessment policies and tools for addressing radioactively contaminated sites by the Superfund program. EPA has almost completed two risk assessment tools that are particularly relevant to decommissioning activities conducted under CERCLA authority. These are the: 1. Building Preliminary Remediation Goals for Radionuclides (BPRG) electronic calculator, and 2. Radionuclide Outdoor Surfaces Preliminary Remediation Goals (SPRG) electronic calculator. EPA developed the BPRG calculator to help standardize the evaluation and cleanup of radiologically contaminated buildings at which risk is being assessed for occupancy. BPRGs are radionuclide concentrations in dust, air and building materials that correspond to a specified level of human cancer risk. The intent of SPRG calculator is to address hard outside surfaces such as building slabs, outside building walls, sidewalks and roads. SPRGs are radionuclide concentrations in dust and hard outside surface materials. EPA is also developing the 'Radionuclide Ecological Benchmark' calculator. This calculator provides biota concentration guides (BCGs), also known as ecological screening benchmarks, for use in ecological risk assessments at CERCLA sites. This calculator is intended to develop ecological benchmarks as part of the EPA guidance 'Ecological Risk Assessment Guidance for Superfund: Process for Designing and Conducting Ecological Risk

  4. Two Superfund environmental justice case studies

    SciTech Connect

    Hirschhorn, J.S.

    1997-12-31

    One of the environmental contributions of the Clinton Administration was Executive Order No. 12898 on Environmental Justice issued in 1994. Environmental justice has received considerable attention in EPA`s Superfund program. Many Superfund sites are located in or close by residential areas composed populated by ethnic minorities and people of the lowest economic status. Over the years, minority communities have often asserted that they have been treated more unfairly than predominantly white, middle class communities, with respect to the quality of environmental cleanups and the relocation of residents. The environmental justice claim is also that these communities have been intentionally placed in harm`s way because of historical racial prejudice and injustice, meaning that either polluting industrial facilities were intentionally placed in minority neighborhoods or that residential areas for minority workers were built close to industrial facilities. This paper presents discussions of two Superfund sites where environmental justice issues have been very important, and it analyzes how specific parts of the Executive Order have been complied with in EPA`s Superfund program.

  5. Recovering value from the Avtex Fibers Superfund site: A case history

    Blasko, M.J.; DeTemple, M.I.

    1994-12-31

    The Avtex Superfund site is located in Front Royal, Virginia. Some recent activities at Avtex have followed an innovative path. This innovative path provides some hope that government regulators and entrepreneurs can coexist in mutually beneficial relationships at potentially valuable Superfund sites. Manufacturing operations at the Avtex site began in 1940. The site produced viscose rayon from wood pulp. Contaminants at the site include sodium hydroxide, carbon disulfide, viscose, sulfuric acid, sodium sulfate, and zinc sulfate. Other contaminants identified at the site include asbestos, PCBs, and hydrogen sulfide. Recognizing the health and safety hazards at the site, the US Environmental Protection Agency (USEPA) developed and issued a Consent Order that governs asset removal activities at the site. The Consent Order requires individuals planning to remove assets to develop a Work Plan for asset removal, as well as cleanup.

    A 123-km stretch of the Kalamazoo River in Michigan, was designated a Superfund site in 1990 due to historical releases of effluent containing polychlorinated biphenyl (PCB)-contaminated paper waste. Risk to bird species in the river ecosystem was evaluated using the tree swallow (Tachycineta bicolor) as a monitor for possible effects due to PCB exposure at two nesting locations, one in the Superfund site and one in an upstream reference location that is less contaminated with PCBs. In 2 of the 3 years of the study, clutch size at the contaminated location was 3.7 +/- 1.4 and 4.8 +/- 0.73 eggs per nest (mean +/- SD), which was significantly less than the clutch size at the reference location (5.0 +/- 1.1 and 5.3 +/- 1.1 eggs per nest). However, there were no statistically significant differences in fledging success, predicted brood size, predicted number of fledglings, or growth of nestlings between the Kalamazoo River Superfund site and an upstream reference location with lesser concentrations of PCBs in the sediments and riparian soils. Productivity and hatching success comparisons between these same sites were also not significantly different; however, the power of these conclusions was less (p < .10). The reduction in clutch size at the co-contaminated location could not be attributed to PCBs due to a number of confounding factors, including Co-cocontaminants, habitat structure, and food availability. Other reproductive parameters were not significantly impaired, and the size of the newly established colony at the Kalamazoo River Superfund site continued to grow over the period of the study. These site-specific observations, combined with multiple lines of evidence approach that considered results reported for the effects of both total PCBs and 2,3,7,8 tetrachlorodibenzo-p-dioxin equivalents (TEQ) on tree swallows at other locations, suggest that there were no significant population-level effects of PCBs on tree swallows at the Kalamazoo River Superfund site.

  12. Superfund and contamination of workers' homes.

    PubMed

    Zirschky, J; Gentry, B; Marcus, P

    1987-11-01

    Although originally conceived as a means to clean up abandoned hazardous waste sites, at least one state is now attempting to use the Superfund (CERCLA) legislation as a means to recover the costs of a home contamination incident. This case has not been litigated yet. If the state is successful, however, the Superfund program would be expanded not only to cover waste disposal practices but also industrial hygiene practices. Industries thus need to review the nature and disposition of their waste material and their industrial hygiene practices in order to assess their full potential exposure under Superfund. The small amounts of chemicals that may leave a factory on workers' clothing and shoes someday could develop into a costly home decontamination project. If a review of past and present industrial hygiene practices reveals that home contamination could have occurred, an industry should take an offensive (as opposed to defensive) role in correcting the problem. Not only can taking the initiative in remedying a problem help minimize damage to employee health, morale and public opinion, but clean-up costs can be reduced as well without sacrificing the quality of the remedial action.

  13. Congressman Mike Oxley talks about Superfund reform

    1995-10-01

    The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is currently undergoing an extensive review in both the US House of Representatives and Senate. Congress is under some time pressure in its work, as the program`s taxing authority expires at the end of this year. During the last Congress, a coalition of environmentalists, industry members, and others supported reform legislation. However, the 103rd Congress and the coalition`s efforts ultimately failed for various reasons, including Congressional opposition at that time to including a broad risk assessment measure with the Superfund bill. With the November 1994 election, a Republic majority took over both the House and the Senate, and with it came changes; among the changes were new congressional Committee chairmen. National Ground Water Association staff recently spoke with Congressman Michael G. Oxley (R-OH), the new chairman of the House Commerce, Trade, and Hazardous Materials Subcommittee. This House Subcommittee is responsible for Superfund reauthorization issues. Congressman Oxley will play a key role in any Superfund legislation that is drafted and may eventually pass in the 104th Congress.

  15. On the brink of reform: Four bills vie for the Superfund reauthorization title

    SciTech Connect

    Zodrow, J.J.

    1995-12-01

    After months of hearings in the House of Representatives and the Senate, Congress is poised to reform the Comprehensive Environmental Response, Compensation and Liability Act of 1980. Without CERCLA reauthorization, no federal tax dollars will be allocated to the Superfund for remediating contaminated industrial sites. Authorization to pay into the Superfund expired officially in 1994, and only $2.8 billion remains in the trust fund, enough to run the program through next September at its current annual budget of $1.4 billion. Critics state that Congress acted ambitiously in enacting CERCLA 15 years ago in response to a general belief that only dozens of contaminated sites existed and could be addressed within a few years. However, the Environmental Protection Agency since 1980 has named 1,300 sites to the National Priorities List. Many contend that the Superfund program was not designed to be a clearinghouse for a multitude of site cleanups. CERCLA`s complicated procedural requirements and taxing transactional costs, some say, were intended to apply to a few, highly toxic sites.

    Remediation of ground water and soil contamination at the Wells G & H Superfund Site, Woburn, Massachusetts, uses technologies that reflect differences in hydrogeologic settings, concentrations of volatile organic compounds (VOCs), and costs of treatment. The poorly permeable glacial materials that overlie fractured bedrock at the W.R. Grace property necessitate use of closely spaced recovery wells. Contaminated ground water is treated with hydrogen peroxide and ultraviolet (UV) oxidation. At UniFirst, a deep well completed in fractured bedrock removes contaminated ground water, which is treated by hydrogen peroxide, UV oxidation, and granular activated carbon (GAC). The remediation system at Wildwood integrates air sparging, soil-vapor extraction, and ground water pumping. Air stripping and GAC are used to treat contaminated water; GAC is used to treat contaminated air. New England Plastics (NEP) uses air sparging and soil-vapor extraction to remove VOCs from the unsaturated zone and shallow ground water. Contaminated air and water are treated using separate GAC systems. After nine years of operation at W.R. Grace and UniFirst, 30 and 786 kg, respectively, of VOCs have been removed. In three years of operation, 866 kg of VOCs have been removed at Wildwood. In 15 months of operation, 36 kg of VOCs were removed at NEP. Characterization work continues at the Olympia Nominee Trust, Whitney Barrel, Murphy Waste Oil, and Aberjona Auto Parts properties. Risk assessments are being finalized that address heavy metals in the floodplain sediments along the Aberjona River that are mobilized from the Industri-Plex Superfund Site located a few miles upstream.

    Since 2000, the University of Kentucky's (UK's) Superfund Basic Research Program (SBRP) Community Outreach Core has provided support and guidance through Superfund Community Action through Nutrition (SCAN) programs, which meet the needs of individuals and communities affected by environmental contaminants. It has been shown that nutrition may modulate the toxicity of Superfund chemicals. SCAN programs integrate nutrition education, nutrition science research, and health communication to increase understanding of health risks associated with residing near Superfund sites. Two critical tasks must be accomplished. SCAN personnel must identify and recruit affected community members, and then, offer meaningful programs. Certain quantitative outcome measures and legal issues presented both challenges and opportunities. Community members preferred qualitative evaluation discussions, which showed increased knowledge and improved attitudes following SCAN programs. SCAN, in full partnership with affected communities, translates safe, effective nutrition information to reduce health risks associated with exposure to Superfund pollutants.

  19. Mining-Related Sediment and Soil Contamination in a Large Superfund Site: Characterization, Habitat Implications, and Remediation.

    PubMed

    Juracek, K E; Drake, K D

    2016-10-01

    Historical mining activity (1850-1970) in the now inactive Tri-State Mining District provided an ongoing source of lead and zinc to the environment including the US Environmental Protection Agency Superfund site located in Cherokee County, southeast Kansas, USA. The resultant contamination adversely affected biota and caused human health problems and risks. Remediation in the Superfund site requires an understanding of the magnitude and extent of contamination. To provide some of the required information, a series of sediment and soil investigations were conducted in and near the Superfund site to characterize lead and zinc contamination in the aquatic and floodplain environments along the main-stem Spring River and its major tributaries. In the Superfund site, the most pronounced lead and zinc contamination, with concentrations that far exceed sediment quality guidelines associated with potential adverse biological effects, was measured for streambed sediments and floodplain soils located within or downstream from the most intensive mining-affected areas. Tributary streambeds and floodplains in affected areas are heavily contaminated with some sites having lead and zinc concentrations that are an order of magnitude (or more) greater than the sediment quality guidelines. For the main-stem Spring River, the streambed is contaminated but the floodplain is mostly uncontaminated. Measured lead and zinc concentrations in streambed sediments, lakebed sediments, and floodplain soils documented a persistence of the post-mining contamination on a decadal timescale. These results provide a basis for the prioritization, development, and implementation of plans to remediate contamination in the affected aquatic and floodplain environments within the Superfund site.

    Historical mining activity (1850–1970) in the now inactive Tri-State Mining District provided an ongoing source of lead and zinc to the environment including the US Environmental Protection Agency Superfund site located in Cherokee County, southeast Kansas, USA. The resultant contamination adversely affected biota and caused human health problems and risks. Remediation in the Superfund site requires an understanding of the magnitude and extent of contamination. To provide some of the required information, a series of sediment and soil investigations were conducted in and near the Superfund site to characterize lead and zinc contamination in the aquatic and floodplain environments along the main-stem Spring River and its major tributaries. In the Superfund site, the most pronounced lead and zinc contamination, with concentrations that far exceed sediment quality guidelines associated with potential adverse biological effects, was measured for streambed sediments and floodplain soils located within or downstream from the most intensive mining-affected areas. Tributary streambeds and floodplains in affected areas are heavily contaminated with some sites having lead and zinc concentrations that are an order of magnitude (or more) greater than the sediment quality guidelines. For the main-stem Spring River, the streambed is contaminated but the floodplain is mostly uncontaminated.

    1990-04-01

    EPA has announced final revisions to the National Contingency Plan (NCP), which lays the ground rules for how EPA and other federal agencies, states and private parties clean up hazardous wastes sites and discharges of oil. The new NCP serves to strengthen key areas of the Superfound implementation process as recommended in EPA Administrator William Reily's so called 90-day Management Review in June 1989. The management review emphasized technologies development, public involvement, and realistic goals, such as making sites safer and addressing worst sites first. The National Priorities List (NPL) is EPA's list of those sites posing the greatest danger or potential danger to human health and the environment. There are currently 1219 sites on the NPL. Other issues addressed in the new NCP include informing the public of the types of remedies that EPA has selected, or anticipates selecting; strengthening state involvement by authorizing states to conduct investigations, analyses and remedy selections at federal Superfund sites; and measuring success of site cleanups.

  3. Innovative solutions cut cleanup costs at Sand Creek Superfund site

    1995-03-01

    Remediation of the San Creek Industrial Superfund site, which has been on the Environmental Protection Agency's National Priorities List since 1982, is scheduled for completion by the end of this month. The 300-acre site in the Denver suburb of Commerce City is a former industrial property used at various times for manufacturing agricultural chemicals, petroleum production, and chemical storage and distribution. Portions of the site also were used as a municipal landfill and for acid-waste disposal. Like most hazardous waste disposal sites, Sand Creek posed complex and potentially costly remediation problems. However, use of innovative technical solutions and such cost-saving initiatives as value engineering have allowed the project to proceed on schedule and meet EPA's goal of controlling and reducing remediation costs. Sand Creek became a candidate for the NPL after two fires destroyed its chemical manufacturing plants, leaving behind toxic residues. High levels of volatile organic compounds and metals, as well as other contaminants, were found in the groundwater.

  4. Capacity building in Developing Countries: a challenge ahead for the European Space Agency to continue its successful experience to date

    NASA Astrophysics Data System (ADS)

    Fea, M.

    The European Space Agency (ESA) has built a long tradition and a large experience in the domain of education, training and capacity building throughout its space programmes. As an example, the ESA Science Programme dedicates 1% of its budget to these activities. One of the key reasons for it is the need of closing the loop along the chain from the provider to the user, that is to say between the space and the users elements. In fact, besides the obvious need for technology development, there is actually not very much justification in the long term for a space programme if the user communities are not able to make good use of programme outputs and provide feedback and proper requirements to space agencies. The case of ESA Earth Observation programmes is described to illustrate these considerations, as a way to also implement the European Space Policy and UNISPACE III recommendations. Since its foundation in 1975 and the implementation of its EO programme with the launch of Meteosat-1 in 1977 and the birth of the Earthnet Programme Office in 1978, the European Space Agency is very active in the field of capacity building in developing countries. That is performed through both ESA's specific projects and international co-operation activities. In the latter domain, ESA enjoys a long-standing collaboration with many entities, such as the Committee of Earth Observation Satellites (CEOS), and organisations, such as WMO, UN and its specialised agencies (FAO, UNESCO, UNEP, and so on). In that respect, the Agency is an active member of the CEOS Working Group on Education (WGEdu) and of the World Summit for Sustainable Development Follow-Up (WSSD) Module 1 group dedicated to education, training and capacity building. The overall ESA strategy targets various citizen communities and takes into account the fact that today's young generations will become tomorrow's professionals and decision makers. ESA's activities in this domain are in particular based on an end-to-end concept

  18. Environmental policy and equity: The case of Superfund

    SciTech Connect

    Hird, J.A. )

    1993-01-01

    This article analyzes the equity implications of the EPA's Superfund program by examining the geographic distribution of sites, who pays for cleanup, and cleanup pace. Although the [open quotes]polluter pays[close quotes] principle is used to justify Superfund policy, it is a goal that is not and indeed usually cannot be attained for past contamination. Further, the geographic distribution of Superfund sites suggests that the likely beneficiaries of program expenditures live in counties that are on average both wealthier and more highly educated than the rest, and also have lower rates of poverty. The pace of the EPA's cleanups, however, depends mostly on the sites potential hazard, and is not apparently motivated by the localities socioeconomic characteristics or political representation. The program is found in several respects to be both inefficient and inequitable, yet Superfund enjoys considerable support for reasons beyond these traditional public policy goals, including its political and symbolic appeal. 36 refs., 2 tabs.

    2004-04-02

    The Heckathorn Superfund Site in Richmond, California, encompasses the property of the former United Heckathorn pesticide packaging plant and the adjacent waterway, Lauritzen Channel. The site was used from 1945 to 1966 by several operators to produce various agricultural chemicals. The site was placed on the National Priorities List of Superfund sites in 1990, which resulted in the removal of pesticide-contaminated soil from the upland portion of the site and dredging the marine portion of the site. Post-remediation marine monitoring and associated studies conducted through 2002 indicate that the contamination in the channel continues to pose a significant risk to biota and human health. This report documents continued marine monitoring and source investigation studies conducted in 2003.

    Peroxy-organic acids are formed by the chemical reaction between organic acids and hydrogen peroxide. The peroxy-acid process was applied to two Superfund site soils provided by the U.S. Environmental Protection Agency (EPA). Initial small-scale experiments applied ratios of 3:5:7 (v/v/v) or 3:3:9 (v/v/v) hydrogen peroxide:acetic acid:deionized (DI) water solution to 5g of Superfund site soil. The experiment using 3:5:7 (v/v/v) ratio resulted in an almost complete degradation of the 14 EPA regulated polycyclic aromatic hydrocarbons (PAHs) in Bedford LT soil during a 24-h reaction period, while the 3:3:9 (v/v/v) ratio resulted in no applicable degradation in Bedford LT lot 10 soil over the same reaction period. Specific Superfund site soil characteristics (e.g., pH, total organic carbon content and particle size distribution) were found to play an important role in the availability of the PAHs and the efficiency of the transformation during the peroxy-acid process. A scaled-up experiment followed treating 150g of Bedford LT lot 10 soil with and without mixing. The scaled-up processes applied a 3:3:9 (v/v/v) solution resulting in significant decrease in PAH contamination. These findings demonstrate the peroxy-acid process as a viable option for the treatment of PAH contaminated soils. Further work is necessary in order to elucidate the mechanisms of this process.

    The United States Environmental Protection Agency (EPA) is amending the Record of Decision (ROD) (PB92-964310) for the Mid-America Tanning Company Superfund Site. The ROD presented the remedy selected by the EPA for this site, which called for in-situ immobilization of the densely-contaminated sediments in the east and west aeration lagoons and the northeast field in conjunction with the placement of soil-clay caps over the less densely-contaminated source areas. As a result of information which has been developed subsequent to the issuance of the ROD, the EPA has determined that fundamental changes to the remedy were necessary. The amendment to the ROD describes and summarizes the basis for these changes as well as documenting changes in the remedy at the site.

    2002-12-18

    This report represents Phase I of a multi-phase approach to a source investigation of DDT at the Heckathorn Superfund Site, Richmond, California, the former site of a pesticide packaging plant, and the adjacent waterway, the Lauritzen Channel. Potential identified sources of contamination were from sloughed material from undredged areas (such as side banks) and from outfall pipes. Objectives of Phase I included the (1) evaluation of pesticide concentrations associated with discharge from outfalls, (2) identification of additional outfalls in the area, (3) identification of type, quantity, and distribution of sediment under the Levin pier, (4) quantification of pesticide concentrations in sediment under the pier, and (5) evaluation of sediment structure and slope stability under the pier. Field operations included the collection of sediment directly from inside the mouths of outfall pipes, when possible, or the deployment of specially designed particle traps where direct sampling was problematic. Passive water samplers were placed at the end of known outfall pipes and analyzed for DDT and other pesticides of concern. Underwater dive surveys were conducted beneath the Levin pier to document type, slope, and thickness of sediment. Samples were collected at locations of interest and analyzed for contaminants. Also sampled was soil from bank areas, which were suspected of potentially contributing to continued DDT contamination of the Lauritzen Channel through erosion and groundwater leaching. The Phase I Source Investigation was successful in identifying significant sources of DDT contamination to Lauritzen Channel sediment. Undredged sediment beneath the Levin pier that has been redistributed to the channel is a likely source. Two outfalls tested bear further investigation. Not as well-defined are the contributions of bank erosional material and groundwater leaching. Subsequent investigations will be based on the results of this first phase.

    2015-01-01

    In cooperation with the U.S. Environmental Protection Agency (EPA), Region 3, the U.S. Geological Survey (USGS) is participating in an ongoing study to aid in the identification of subsurface heterogeneities that may act as preferential pathways for contaminant transport in and around the Lower Darby Creek Area (LDCA) Superfund Site, Philadelphia Pa. Lower Darby Creek, which flows into the Delaware River, borders the western part of the former landfill site. In 2013, the USGS conducted surface geophysics measurements and stream porewater sampling to provide additional data for EPA’s site characterization. This report contains data collected from field measurements of direct current (DC) resistivity, frequency-domain electromagnetic (FDEM) surveys, and stream porewater specific conductance (SC).

  13. Great lakes research--important human health findings and their impact on ATSDR's Superfund research program.

    PubMed

    Hicks, Heraline E; De Rosa, Christopher T

    2002-03-01

    The Agency for Toxic Substances and Disease Registry (ATSDR) was created by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, commonly known as Superfund. ATSDR is the principal United States federal public health agency involved with issues of public health and applied science concerning the human health impact of living in the vicinity of a hazardous waste site, or emergencies resulting from unplanned releases of hazardous substances into community environments. In pursuing these mandates, ATSDR's mission is to prevent exposure and adverse human health effects and diminished quality of life associated with exposure to hazardous substances from waste sites, unplanned releases, and other sources of pollution present in the environment. There are more than 2,000 toxic substances found at hazardous waste sites in the United States. ATSDR has developed a prioritized list of 275 substances that pose the greatest hazard to human health. In conducting its work ATSDR has identified data gaps in knowledge about the toxicity of various hazardous substances as well as gaps in human exposure characterization. As part of its mandate, ATSDR initiated a Substance-Specific Applied Research Program (SSARP) to address these data gaps. The ATSDR Great Lakes Human Health Effects Research Program (GLHHERP) is a congressionally-mandated research program that characterizes exposure to persistent toxic substances and investigates the potential for adverse health outcome in at-risk populations. The research findings from this program in the areas of exposure, sociodemographic data, and health effects have significant public health implications for ATSDR's Superfund research activities.

    This report represents a remote sensing research effort conducted by the U.S. Geological Survey in cooperation with the U.S. Environmental Protection Agency (EPA) for the EPA Office of Inspector General. The objective of this investigation was to explore the efficacy of remote sensing as a technology for postclosure monitoring of hazardous waste sites as defined under the Comprehensive Environmental Response Compensation and Liability Act of 1980 (Public Law 96-510, 42 U.S.C. §9601 et seq.), also known as \\"Superfund.\\" Five delisted Superfund sites in Maryland and Virginia were imaged with a hyperspectral sensor and visited for collection of soil, water, and spectral samples and inspection of general site conditions. This report evaluates traditional and hyperspectral imagery and field spectroscopic measurement techniques in the characterization and analysis of fugitive (anthropogenic, uncontrolled) contamination at previously remediated hazardous waste disposal sites.

  6. A critical evaluation of public health programs at the Bunker Hill Superfund site.

    PubMed

    Rosen, John F

    2003-02-15

    Since 1983, the Bunker Hill Superfund site (BHSS) has been the second largest on US Environmental Protection Agency's (EPA) National Priority List for cleanup. Contaminants include millions of tons of Pb, Cd, Hg and As. In 1974, following a bag house fire, 22.1% of young children had blood lead levels >80 microg/dl. In the early 1980s to the present, EPA initiated the cleanup of exterior residential soils and the smelter complex. In 1999, The National Geological Service confirmed that heavy metal pollution had extended from BHSS to Lake Coeur d'Alene (already known earlier) all the way to the Spokane River in Washington State via water borne tributaries linking Idaho and Washington States. This report focuses on public health programs and their results initiated by Federal and State agencies at the BHSS. These programs include blood lead screening, educational programs, exploratory dust control plans, and land transactions. These programs and their results are then evaluated, assessed and critically discussed. The conclusion of this critical evaluation assessment is that the protection of public health has not been adequately addressed or protected by Federal and State agencies.

  8. Guidelines for asbestos remediation at Italian superfund sites.

    PubMed

    Paglietti, F; Malinconico, S; Di Molfetta, V; Giangrasso, M

    2012-01-01

    Asbestos is now banned in 52 countries. Although Italy banned asbestos in 1992, up until that date it had been one of the main producer nations of asbestos and asbestos-containing materials, and asbestos-related contamination is still widespread in the country. To reduce asbestos-related health effects, Italy has adopted many laws and regulations regarding exposure thresholds and remediation tools. Even so, there are legislative gaps that are making it difficult to manage related risks especially in the operative phase. The lack of standard procedures at a national level regarding emergency shutdown and remediation as well as reference thresholds for specific risk situations creates difficulties and different actions when dealing with the cleanup of Italian asbestos superfund sites. The authors propose operative guidelines for asbestos remediation at Italian superfund sites. INAIL, the reference national organization for asbestos-related matters, acting as an advisor to a number of state, regional, and local authorities, examined the main asbestos-related risk situations in Italy and proposed the most appropriate actions to take. The detailed analysis of many actual cases of risk, in part through inspections and the management of cleanup actions at asbestos Italian superfund sites, resulted in proposals to modify existing procedures and thresholds, which were subsequently discussed with all national, regional, and local scientific bodies. After more than two years of work and discussion at a national level, INAIL-DIPIA-Asbestos Group drafted new Guidelines for Asbestos Remediation at Italian Superfund sites, and officially submitted them to the Environment Ministry. The Ministry then adopted the document in regard to all asbestos Italian superfunds. This recently released document is also a useful reference for contaminated sites at a regional and local level. The operative Guidelines for Asbestos Remediation at Italian Superfund sites may also be of use at an

    2009-11-01

    Environmental justice (EJ) is prominent in environmental policy, yet EJ research is plagued by debates over methodological procedures. A well-established economic approach, the hedonic price method, can offer guidance on one contentious aspect of EJ research: the choice of the spatial unit of analysis. Environmental managers charged with preventing or remedying inequities grapple with these framing problems. This article reviews the theoretical and empirical literature on unit choice in EJ, as well as research employing hedonic pricing to assess the spatial extent of hazardous waste site impacts. The insights from hedonics are demonstrated in a series of EJ analyses for a national inventory of Superfund sites. First, as evidence of injustice exhibits substantial sensitivity to the choice of spatial unit, hedonics suggests some units conform better to Superfund impacts than others. Second, hedonic estimates for a particular site can inform the design of appropriate tests of environmental inequity for that site. Implications for policymakers and practitioners of EJ analyses are discussed.

  12. Hazardous waste enforcement. [RCRA and Superfund regulatory programs

    SciTech Connect

    1982-07-01

    A change is taking place in the enforcement of the Resource Conservation and Recovery Act (RCRA) and Superfund, a change described by the terms ''environmental results'' and ''cooperation, no confrontation''. Examples are given of environmental results achieved through criminal enforcement. In June 1981, a New York businessman received a two and one-half year prison sentence for dumping PCB-laced oil along North Carolina roads; a second defendant received an 18-month jail term. Other important measures of environmental results achieved by enforcement are 1) commitment of private money and effort for hazardous waste management and 2) the number of facility inspections conducted under RCRA's regulatory program's compliance monitoring system. A new strategy of cooperation between U.S. EPA and the parties affected by RCRA and Superfund should change the pattern which produced the confrontational conflicts of the past. (JMT)

    1991-02-01

    Superfund celebrated its tenth anniversary in December 1990. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) - popularly known as Superfund - was passed into law in December 1980 in the wake of such incidents as Love Canal and the Valley of the Drums. The program was designed to clean up uncontrolled hazardous waste sites and, during the past ten years, thousands of actions have been taken to protect human health and the environment from the hazards posed by those sites. EPA believes that goal is best met by its strategy: make sites safer - control immediate threats; enforce aggressively; make sites cleaner - worst problems at worst sites first; bring new technology to bear on the problem.

    1995-01-01

    Congressional failure to pass a Superfund reauthorization bill this fall disappointed environmental consulting and engineering companies, environmentalists and parties liable for site cleanups. The Clinton administration's reform bill was introduced in the House Feb. 3, six months overdue, only seven months before Congress' annual summer break and less than a year before mid-term elections. The House bill was revised in August, but reauthorization was declared a lost cause in October, when supporters faced the harsh political fact that Republicans would hold the line against passing a new law until after the November elections. Of the three major environmental laws overdue for reauthorization--the Resource Conservation and Recovery Act, Clean Water Act and Superfund (officially, the Comprehensive Environmental Response, Compensation and Liability Act)--the Superfund law appears to have the best chance of making it through the 104 Congress successfully. The latest version of the administration-sponsored bill received wide-spread support from environmentalists, industry and environmental business groups as being more reasonable and fair than the existing law.

    Background The Superfund Research Program (SRP) is an academically based, multidisciplinary, translational research program that for 25 years has sought scientific solutions to health and environmental problems associated with hazardous waste sites. SRP is coordinated by the National Institute of Environmental Health Sciences (NIEHS). It supports multi-project grants, undergraduate and postdoctoral training programs, individual research grants, and Small Business Innovation Research (SBIR) and Technology Transfer Research (STTR) grants. Results SRP has had many successes: discovery of arsenic’s toxicity to the developing human central nervous system; documentation of benzene toxicity to hematologic progenitor cells in human bone marrow; development of novel analytic techniques such as the luciferase expression assay and laser fragmentation fluorescence spectroscopy; demonstration that PCBs can cause developmental neurotoxicity at low levels and alter the genomic characteristics of sentinel animals; elucidation of the neurodevelopmental toxicity of organophosphate insecticides; documentation of links between antimicrobial agents and alterations in hormone response; discovery of biological mechanisms through which environmental chemicals may contribute to obesity, atherosclerosis, diabetes, and cancer; tracking the health and environmental effects of the attacks on the World Trade Center and Hurricane Katrina; and development of novel biological and engineering techniques to facilitate more efficient and lower-cost remediation of hazardous waste sites. Conclusion SRP must continue to address the legacy of hazardous waste in the United States, respond to new issues caused by rapid advances in technology, and train the next generation of leaders in environmental health science while recognizing that most of the world’s worst toxic hot spots are now located in low- and middle-income countries.

The ROD is a public document signed by the appropriate Regional Administrator which details cleanup, cost estimates, and EPA`s responsiveness to the public comment summary. The ROD may be litigated, thus it is important to have all current updates to the signed EPA decision. The ROD may be amended with an Amendment or supplemented by an Explanation of Significant Difference (ESD). A Superfund Site may have multiple RODs, as each Superfund Site may be further redefined as Operable Units and Events. This allows EPA`s decisions to evolve as new technology presents itself. Average clean-up time for a Superfund Site can range from 12 to 100 years.

    Although widely recognized as the most efficient means of water purification, reverse osmosis has not been considered effective for remediating hazardous wastewater. Scaling and fouling, which can cause overruns and downtime, and require membrane replacement, have inhibited success in high-volume wastewater applications. Despite this background, a reverse osmosis technology developed in Europe recently was used successfully to treat large volumes of contaminated water at a major Superfund site in Texas. The technology's success there may increase the chances for reverse osmosis to find wider use in future cleanups and other waste treatment applications.

Additionally the project addresses the needs identified during the projects initial phases. By implementing this project, the following outcomes were sought: (1) State regulatory agencies implemented more formalized environmental risk management practices as they pertain to the production of oil and gas, and injection via Class II wells. (2) Enhancement of oil and gas production by implementing a management system supporting the saving of abandoned or idle wells located in areas with a relatively low environmental risk of endangering underground sources of drinking water (USDWs) in a particular state. (3) Verification that protection of USDWs is adequate and additional restrictions of requirements are not necessary in areas with a relatively low environmental risk. (4) Standardization of data and information maintained by state regulatory agencies and decrease the regulatory cost burden on producers operating in multiple states, and (5) Development of a system for electronic data transfer among operators and state regulatory agencies and reduction of overall operator reporting burdens.

    From 1963 to 1969, two acres of the Harvey and Knott Drum site in New Castle County, Delaware served as an open dump and burning area for sanitary, municipal, and industrial wastes. Sludge, paint pigment, and solvents contaminated the site until the State of Delaware and the US Environmental Protection Agency (EPA) intervened in 1981. Site conditions required a combination of traditional cleanup measures. After the immediate health threats posed by the site were eliminated, EPA reached an innovative, mixed funding settlement for long-term cleanup with two parties responsible for the site contamination. The following actions highlight the success of the Superfund program: An emergency removal of contaminants reduced immediate environmental and public health effects; A rapid assessment of ground water safeguarded drinking water supplies; and The full cooperation of General Motors (GM) expedited implementation of the cleanup, valued at $3.2 million.

    1992-01-01

    Investigation, mitigation, and clean-up of hazardous materials at Superfund sites normally require on-site workers to perform hazardous and sometimes potentially dangerous functions. Such functions include site surveys and the reconnaissance for airborne and buried toxic environmental contaminants. Workers conducting on-site air monitoring risk dermal, ocular and inhalation exposure to hazardous chemicals, while those performing excavations also risk in addition the potential exposure to fire, explosion, and other physical injury. EPA's current efforts to protect its workers and mitigate these risks include the use of robotic devices. Using robots offers the ultimate in personnel protection by removing the worker from the site of potential exposure. The paper describes the demonstration of a commercially-available robotic platform modified and equipped for air monitoring and the ongoing research for the development of a ground penetrating radar (GPR) system to detect buried chemical waste drums. These robotic devices can be ultimately routinely deployed in the field for the purpose of conducting inherently safe reconnaissance activities during Superfund/SARA remedial operations.

    The Superfund program to clean-up past hazardous waste releases of national significance failed to be reauthorized in the last Congress, leaving a number of issues to be resolved in the uncertain climate of the new Congress and in the run-up to the next Presidential election. As the bellwether of clean-up, decisions about Superfund will set the pattern to be followed in actions on federal facilities, on currently operating (RCRA) facilities, and on sites not now under the federal umbrella. Total expenditures on these programs will be on the order of $750 billion over the next 30 years. The tax which supports federal action does not expire until the end of 1995 and accumulated funds will finance activity through much of 1996, but some action can not long be delayed. This paper analyzes some of the issues left unresolved. These include the criteria for clean-up(the {open_quotes}how clean is clean{close_quotes} issue); the role of risk in determining action, especially with respect to future land use scenarios; the flexibility to be accorded new technologies; the appropriate distribution of the costs; the criteria to be used in assessing benefits; an the role to be given to stakeholders.

    The creosote- and pentachlorophenol-contaminated aquifer at the Libby Superfund Site is being bioremediated using naturally occurring aerobic microorganisms. Water is injected into the aquifer downgradient from the major contaminant source area. Between January 1991 and May 1993, the injection water was amended with hydrogen peroxide at a delivered concentration of approximately 100 mg/L. Theoretically, this hydrogen peroxide decomposed in the aquifer to produce approximately 50 mg/L of biologically available dissolved oxygen. The use of hydrogen peroxide was successful in making portions of the aquifer aerobic, which reduced water-phase contaminant concentrations. In May 1993, the hydrogen peroxide system was replaced by an oxygen generation/dissolution system that reduced the operating costs for oxygenating the aquifer by about $35,000 annually. Oxygen is now generated on site by a pressure-swing absorption oxygen generator and is dissolved by four membrane oxygen dissolution devices. The membrane oxygen dissolution system has operated at the Libby Superfund site for more than 26 months with no loss in performance due to membrane fouling or membrane fatigue.

    The NIEHS funds several basic and applied research programs, many of which also require research translation or outreach. This paper reports on a project by the Brown University Superfund Basic Research Program (SBRP), in which outreach and research translation teams collaborated with state regulatory agency personnel and community activists on a legislative initiative to mitigate the financial impacts of living in a contaminated community. The Environmentally Compromised Home Ownership (ECHO) program makes home equity loans of up to $25,000 available to qualified applicants. This collaboration provides a case study in community engagement and demonstrates how research translation and outreach activities that are clearly differentiated yet well-integrated can improve a suite of basic and applied research. Although engaging diverse constituencies can be difficult community-engaged translation and outreach have the potential to make research findings more useful to communities, address some of the social impacts of contamination, and empower stakeholders to pursue their individual and collectively held goals for remediation. The NIEHS has recently renewed its commitment to community-engaged research and advocacy, making this an optimal time to reflect on how basic research programs that engage stakeholders through research translation and outreach can add value to the overall research enterprise.

    Laser-ablation inductively coupled-plasma mass-spectrometry analysis of red oak (Quercus rubra) from a well documented heavy metal contaminated United States Environmental Protection Agency superfund site in Woburn, Massachusetts reveals decade-long trends in Pb contaminant sources. Lead isotope ratios (207Pb/206Pb and 208Pb/206Pb) in tree rings plot along a linear trend bracketed by several local and regional contamination sources. Statistically significant interannual variations in 207Pb/206Pb suggest that atmospheric Pb is rapidly incorporated into wood, with minimal mobility subsequent to deposition in annual growth rings. We interpret the decadal trends in our record as a changing mixture of local pollution sources and gasoline-derived Pb. Between 1940 and 1970, Pb was predominantly derived from remobilization of local industrial Pb sources. An abrupt shift in 207Pb/206Pb may indicate that local Pb sources were overwhelmed by gasoline-derived Pb during the peak of leaded gasoline emissions in the late 1960s and early 1970s.

    Groundwater beneath a former chemical reclamation facility in New Jersey is contaminated with metals and organic compounds. The off-site migration of these compounds has not been studied; however, a nearby public-supply well is contaminated, and a public-supply well 1,400 ft downgradient from the site may be threatened. The study is underlain by alluvial deposits composed of gravel, sand, silt, and clay. These deposits comprise the water table aquifer, the confining units, and the confined aquifer throughout the study area. The water table beneath the Swope Oil Superfund site is approximately 17 ft below sea level and groundwater levels throughout the study area are below the stage of the Delaware River. The aquifer system is recharged by precipitation, leakage of water through confining units, and the water induced from the Delaware River. Five public supply-well fields, primarily adjacent to the Delaware River, and four waste disposal sites with observation well networks are located in the study area. Both the water table and confined aquifers are contaminated in several locations. The concentration of metals and/or purgeable organic compounds in more than 20 wells exceeds the US Environmental Protection Agency primary drinking-water standard and the New Jersey Department of Environmental Protection recommended drinking water criteria. Selected data from wells and test borings are presented, including well construction details; drillers', geologists', and geophysical logs; water levels; specific-capacity and slug test data; and chemical analysis of groundwater samples. 35 refs., 5 figs., 14 tabs.

    A series of pilot-scale incineration tests were performed at the U.S. Environmental Protection Agency's (EPA's) Incineration Research Facility to evaluate the potential of incineration as an option to treat contaminated soils from the Drake Chemical Superfund site in Lock Haven, Pennsylvania. The soils at the Drake site are reported to be contaminated to varying degrees with various organic constituents and several hazardous constituent trace metals. The purpose of the test program was to evaluate the incinerability of selected site soils in terms of the destruction of contaminant organic constituents and the fate of contaminant trace metals. All tests were conducted in the rotary kiln incineration system at the IRF. Test results show that greater than 99.995 percent principal organic hazardous constituent (POHC) destruction and removal efficiencies (DRE) can be achieved at kiln exit gas temperatures of nominally 816 C (1,500 F) and 538 C (1,000 F). Complete soil decontamination of semivolatile organics was achieved; however, kiln ash levels of three volatile organic constituents remained comparable to soil levels.

    2004-01-01

    On April 14?15, 2003, geophysical logging was conducted in five open-borehole wells in and adjacent to the Sharon Steel Farrell Works Superfund Site, Mercer County, Pa. Geophysical-logging tools used included caliper, natural gamma, single-point resistance, fluid temperature, and heatpulse flowmeter. The logs were used to determine casing depth, locate subsurface fractures, identify water-bearing fractures, and identify and measure direction and rate of vertical flow within the borehole. The results of the geophysical logging were used to determine the placement of borehole screens, which allows monitoring of water levels and sampling of water-bearing zones so that the U.S. Environmental Protection Agency can conduct an investigation of contaminant movement in the fractured bedrock. Water-bearing zones were identified in three of five boreholes at depths ranging from 46 to 119 feet below land surface. Borehole MR-3310 (MW03D) showed upward vertical flow from 71 to 74 feet below land surface to a receiving zone at 63-68 feet below land surface, permitting potential movement of ground water, and possibly contaminants, from deep to shallow zones. No vertical flow was measured in the other four boreholes.

    Presently, the BLM (Bureau of Land Management) has identified a multitude of abandoned mine sites in primarily Western states for cleanup. These sites are prioritized and appropriate cleanup has been called in to reclaim the sites. The task is great in needing considerable amounts of agency resources. For instance, in Colorado alone there exists an estimated 23,000 abandoned mines. The problem is not limited to Colorado or to the United States. Cooperation for reclamation is sought at local, state, and federal agency level to aid in identification, inventory, and cleanup efforts. Dangers posed by abandoned mines are recognized widely and will tend to increase with time because some of these areas are increasingly used for recreation and, in some cases, have been or are in the process of development. In some cases, mines are often vandalized once they are closed. The perpetrators leave them open, so others can then access the mines without realizing the danger posed. Abandoned mine workings often fill with water or oxygen-deficient air and dangerous gases following mining. If the workings are accidentally entered into, water or bad air can prove fatal to those underground. Moreover, mine residue drainage negatively impacts the local watershed ecology. Some of the major hazards that might be monitored by higher-resolution satellites include acid mine drainage, clogged streams, impoundments, slides, piles, embankments, hazardous equipment or facilities, surface burning, smoke from underground fires, and mine openings.

    The Environmental Protection Agency (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) and the Nuclear Regulatory Commission (NRC) are responsible for implementing the 'Memorandum of Understanding Between the Environmental Protection Agency and the Nuclear Regulatory Commission: Consultation and Finality on Decommissioning and Decontamination of Contaminated Sites'. This paper provides a brief overview of the origin of the Memorandum of Understanding (MOU), the major features of the MOU, and how the MOU has been implemented site specifically. EPA and NRC developed the MOU in response to direction from the House Committee on Appropriations to EPA and NRC to work together to address the potential for dual regulation. The MOU was signed by EPA on September 30, 2002 and NRC on October 9, 2002. The two agencies had worked on the MOU since March 2000. While both EPA and NRC have statutory authority to clean up these sites, the MOU provides consultation procedures between EPA and NRC to eliminate dual regulation. Under the MOU, EPA and NRC identified the interactions of the two agencies for the decommissioning and decontamination of NRC-licensed sites and the ways in which those responsibilities will be exercised. Except for Section VI, which addresses corrective action under the Resource Conservation and Recovery Act (RCRA), this MOU is limited to the coordination between EPA, when acting under its CERCLA authority, and NRC, when a facility licensed by the NRC is undergoing decommissioning, or when a facility has completed decommissioning, and the NRC has terminated its license. EPA believes that implementation of the MOU between the two agencies will ensure that future confusion about dual regulation does not occur regarding the cleanup and reuse of NRC-licensed sites. NRC and EPA have so far exchanged MOU consultation letters on eight NRC-licensed sites. EPA has responded to each consultation request with a letter expressing its views on actions

    2007-12-01

    Perchlorate, a chemical that had been known both in nature and through synthesis since the nineteenth century, only emerged into the limelight as an environmental contaminant in 1997. US EPA's Superfund Program became involved in perchlorate issues in the late 1980s and early 1990s due to the chemical's presence mixed with other contaminants at cleanup sites. Relying largely on pharmaceutical studies primarily from the 1950s and 1960s, EPA scientists in 1992 made a provisional estimate of toxicity and estimated that about 4 micrograms per liter (parts per billion or ppb) in drinking water would be protective. "Uncertainty factors" were incorporated to address for several identified information gaps. Results of new animal and human studies funded by the Defense Department and industry in the late 1990s shifted the concern from affects on adults with unhealthy thyroids to the potential developmental health risks to infants and children. EPA's January, 2002, draft toxicity assessment was referred to a committee of the National Research Council. In January, 2005, this committee recommended a "reference dose" based primarily on human clinical data. Many decisions remain on interpretation of the scientific recommendations for regulatory applications. After California's 1997 development of an analytical method to detect perchlorate in water to 4 ppb, EPA and state officials quickly discovered this chemical at 10 Superfund sites in the Pacific Southwest Region and at more than 30 other locations in California, Arizona and Nevada. Even before current research on the potential for natural sources of this anion, reported detections of perchlorate were investigated with reasonable care and appropriate skepticism. A brief overview of the search for likely sources of perchlorate detected in California water supplies is presented from a regional Superfund perspective. Some are clearly anthropogenic and others may be unrelated to industrial or disposal practices. Currently, there

    Studies were completed on treating a leachate from New Lyme, Ohio. The leachate was transported to Cincinnati, Ohio, where a pilot-sized rotating biological contactor (RBC) was used for a treatment evaluation. The biomass was developed on the RBC discs with primary effluent from the City of Cincinnati's Mill Creek Sewage Treatment Facility. Experiments were then conducted to determine the effectiveness of treating a hazardous waste leachate and to provide information on the following: the rate of organics removal; the final effluent quality; the fate of priority pollutants and specific organic compounds; and the loss of volatiles via stripping in the RBC. The paper reports on the results from these experiments and the applicability of an RBC to treat a hazardous-waste leachate from a Superfund site.

    In-situ chemical oxidation (ISCO) has gained support as a remediation technique for immiscible-liquid contaminated source zones. 1,1-dichloroethene (DCE) is present at the Samsonite Building Area, which is part of the Tucson International Airport Authority Superfund Site. Based on prior site characterization, DCE is thought to be located in a lower permeability zone adjacent to the water table of a local groundwater zone. A pilot-scale ISCO demonstration project using potassium permanganate (KMnO4) was conducted at the site. Bench-scale studies using core samples were used to determine natural oxidant demand and establish optimal KMnO4 injection concentration. Single, sequential, low-pressure injections were implemented for a 9-well network encompassing the primary source zone. Groundwater monitoring was performed before, during, and after injection.

    In Berlin, New Hampshire, USA, the Androscoggin River flows adjacent to a former chlor-alkali facility that is a US Environmental Protection Agency Superfund site and source of mercury (Hg) to the river. The present study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic-level taxa in the river. Surface sediment directly adjacent to the source showed significantly elevated MeHg (10-40× increase, mean ± standard deviation [SD]: 20.1 ± 24.8 ng g(-1) dry wt) and total mercury (THg; 10-30× increase, mean ± SD: 2045 ± 2669 ng g(-1) dry wt) compared with all other reaches, with sediment THg and MeHg from downstream reaches elevated (3-7× on average) relative to the reference (THg mean ± SD: 33.5 ± 9.33 ng g(-1) dry wt; MeHg mean ± SD: 0.52 ± 0.21 ng g(-1) dry wt). Water column THg concentrations adjacent to the point source for both particulate (0.23 ng L(-1)) and dissolved (0.76 ng L(-1)) fractions were 5-fold higher than at the reference sites, and 2-fold to 5-fold higher than downstream. Methylmercury production potential of periphyton material was highest (2-9 ng g(-1) d(-1) dry wt) adjacent to the Superfund site; other reaches were close to or below reporting limits (0. 1 ng g(-1) d(-1) dry wt). Total Hg and MeHg bioaccumulation in fauna was variable across sites and taxa, with no clear spatial patterns downstream of the contamination source. Crayfish, mayflies, and shiners showed a weak positive relationship with porewater MeHg concentration.

    We previously reported the presence of environmentally persistent free radicals (EPFRs) in pentachlorophenol (PCP) contaminated soils at a closed wood treatment facility site in Georgia. The reported EPFRs were pentachlorophenoxyl radicals formed on soils under ambient conditions via electron transfer from PCP to electron acceptors in the soil. In this study, we present results for soil and sediment samples from additional Superfund sites in Montana and Washington. Paramagnetic centers associated with different chemical environments were characterized by distinct g-factors and line widths (ΔHp-p). EPFR concentrations in contaminated samples were ~30×, ~12×, and ~2× higher than background samples at the Georgia, Montana, and Washington sites, respectively. EPR signals in the Montana contaminated soils were very similar to those previously observed for pentachlorophenol contaminated soils at the Georgia site, i.e., g = 2.00300 and ΔHp-p = 6.0 G, whereas signals in the Washington sediment samples were similar to those previously observed for other PAH contaminated soils, i.e., g = 2.00270 and ΔHp-p = 9.0 G. Total carbon content measurements exhibited direct correlation with EPFR concentration. The presence of radicals in sites contaminated a decade to a century ago suggests continuous formation of EPFRs from molecular contaminants in the soil and sediment.

The decision is based upon the contents of the Administrative Record for the site. The actual or threatened releases of hazardous substances from this site, if not addressed by implementing the response action in this Record of Decision (ROD), may present an imminent and substantial endangerment to public health, selfare, or the environment. The remedy selected for ground water contamination includes continued monitoring of the shallow and intermediate aquifers at the site as well as monitoring of surface water and sediments. The selected remedy also incorporates institutional controls on the placement of drinking water wells and natural attenuation of shallow contaminated ground water.

  15. Air-water exchange of PAHs and OPAHs at a superfund mega-site.

    Chemical fate is a concern at environmentally contaminated sites, but characterizing that fate can be difficult. Identifying and quantifying the movement of chemicals at the air-water interface are important steps in characterizing chemical fate. Superfund sites are often suspected sources of air pollution due to legacy sediment and water contamination. A quantitative assessment of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAH (OPAHs) diffusive flux in a river system that contains a Superfund Mega-site, and passes through residential, urban and agricultural land, has not been reported before. Here, passive sampling devices (PSDs) were used to measure 60 polycyclic aromatic hydrocarbons (PAHs) and 22 oxygenated PAH (OPAHs) in air and water. From these concentrations the magnitude and direction of contaminant flux between these two compartments was calculated. The magnitude of PAH flux was greater at sites near or within the Superfund Mega-site than outside of the Superfund Mega-site. The largest net individual PAH deposition at a single site was naphthalene at a rate of -14,200 (±5780) (ng/m(2))/day. The estimated one-year total flux of phenanthrene was -7.9×10(5) (ng/m(2))/year. Human health risk associated with inhalation of vapor phase PAHs and dermal exposure to PAHs in water were assessed by calculating benzo[a]pyrene equivalent concentrations. Excess lifetime cancer risk estimates show potential increased risk associated with exposure to PAHs at sites within and in close proximity to the Superfund Mega-site. Specifically, estimated excess lifetime cancer risk associated with dermal exposure and inhalation of PAHs was above 1 in 1 million within the Superfund Mega-site. The predominant depositional flux profile observed in this study suggests that the river water in this Superfund site is largely a sink for airborne PAHs, rather than a source.

  16. Temporal and Spatial Distribution of Selected Species of Mercury, Carson River Superfund Site, Nevada

    The Carson River Mercury Site in western Nevada was added to the US Environmental Protection Agency (USEPA) "Superfund" List in 1990 due to contamination from mercury used to amalgamate silver and gold from Comstock Lode ores milled during the late 1800s. The U.S. Geological Survey (USGS) has monitored concentrations of suspended sediment (SS), total mercury (THg) and methylmercury (MeHg) as well as streamflow upstream and downstream of Lahontan Reservoir since 1997 in support of USEPA Remedial Investigations. Differences between inflow and outflow concentrations indicate that nearly 90 percent of SS and unfiltered THg, and at least 50 percent of unfiltered MeHg and filtered (<0.45 μm) THg and MeHg is retained in the reservoir. However, outflow MeHg concentrations exceeded mean inflow concentration (2.9 nanograms per liter; ng/L) in 10 of 135 samples, indicating augmented mercury methylation. During August 2010 and June-September 2011, limnological profiles were measured and water samples collected from discrete depths in each of the reservoir's 3 sub-basins, the inflow delta and 2 shallow and rarely inundated overflow basins to investigate mercury distribution and methylation. In most samples, MeHg concentrations were less than 5 ng/L and increased by less than 1 ng/L in deeper samples. After temperature, oxygen, and Eh profiles indicated thermal stratification in the deep (~25 m) lower basin, samples from the top 1 m still had less than 2 ng/L MeHg but samples collected from 2 m above the sediment-water interface yielded concentrations as high as 220 ng/L in filtered water samples, accounting for 100 percent of filtered and 65 percent of unfiltered THg concentrations in concurrently-sampled water. We hypothesize that anoxic conditions and decomposition of mercury-contaminated plankton and sulfate-reduction in the hypolimnion provide carbon and mercury necessary for mercury methylation that exceeds diffusion from bottom sediment.

    1990-01-01

    Groundwater beneath a former chemical reclamation facility in New Jersey is contaminated with metals and organic compounds. The off-site migration of these compounds has not been studied; however, a nearby public-supply well is contaminated, and a public-supply well 1,400 ft downgradient from the site may be threatened. The study area, in the New Jersey part of the Atlantic Coastal Plain, is underlain by alluvial deposits composed of gravel, sand, silt, and clay. These deposits comprise the water table aquifer, the confining units, and the confined aquifer throughout the study area. The water table beneath the Swope Oil Superfund site is approximately 17 ft below sea level and groundwater levels throughout the study area are below the stage of the Delaware River. The aquifer system is recharged by precipitation, leakage of water through confining units, and the water induced from the Delaware River. Five public supply-well fields, primarily adjacent to the Delaware River, and four waste disposal sites with observation well networks are located in the study area. Both the water table and confined aquifers are contaminated in several locations. The concentration of metals and/or purgeable organic compounds in more than 20 wells exceeds the U.S. Environmental Protection Agency primary drinking-water standard and the New Jersey Department of Environmental Protection recommended drinking water criteria. Selected data from wells and test borings are presented, including well construction details; drillers ', geologists ', and geophysical logs; water levels; specific-capacity and slug test data; and chemical analysis of groundwater samples.

    A study was conducted by the U.S. Geological Survey and the U.S. Environmental Protection Agency to define the geohydrology and contaminant distribution at a Superfund site near Byron, Illinois. Geologic units of interest beneath the site are the St. Peter Sandstone; the shale, dolomite and sandstone of the Glenwood Formation; the dolomite of the Platteville and Galena Groups; and sands, gravels, tills and loess of Quaternary age. The hydrologic units of interest are the unconsolidated aquifer, Galena-Platteville aquifer, Harmony Hill Shale semiconfining unit, and the St. Peter aquifer. Ground-water flow generally is from the upland areas northwest and southwest toward the Rock River. Water levels indicate the potential for downward ground-water flow in most of the area except near the Rock River. The Galena-Platteville aquifer can be subdivided into four zones characterized by differing water-table altitudes, hydraulic gradients, and vertical and horizontal permeabilities. Geophysical, hydraulic, and aquifer-test data indicate that lithology, stratigraphy, and tectonic structures affect the distribution of primary and secondary porosity of dolomite in the Galena and Platteville Groups, which affects the permeability distribution in the Galena-Platteville aquifer. The distribution of cyanide, chlorinated aliphatic hydrocarbons, and aromatic hydrocarbons in ground water indicates that these contaminants are derived from multiple sources in the study area. Contaminants in the northern part of this area migrate northwest to the Rock River. Contaminants in the central and southern parts of this area appear to migrate to the southwest in the general direction of the Rock River.

    Closure of the groundwater component of a major Superfund site has been accomplished by a combination of source control, engineered in-situ bioremediation, and subsequent long-term intrinsic bioremediation. Engineered bioremediation outside the source control area resulted in very significant contaminant mass removal. This allowed intrinsic bioremediation to be considered as a passive remedial management method of achieving cleanup objectives after active remediation needed. Modeling demonstrated that intrinsic bioremediation would achieve cleanup objectives (for this site, Federal drinking water standards) within ten years of shutdown of the active bioremediation system. Modeling showed that residual electron acceptors and nutrients distributed in the aquifer during engineered bioremediation greatly enhance the intrinsic bioremediation process. The results of the modeling effort led to the active system being shut down a year ahead of schedule, allowing the project to move into a low-maintenance intrinsic bioremediation and long-term monitoring phase. The modeling demonstration coupled Visual MODFLOW{copyright} and BioTrans{copyright} to simulate groundwater flow, solute transport, and oxygen-limited, multi-species biodegradation. Regional flow evaluation, detailed model sensitivity analyses, and subarea modeling were employed to provide support to model predictions. Predictions will be tested by subsequent progress and compliance monitoring. Site closure began in early 1996.

  3. The New Bedford Harbor Superfund Site Long Term ...

    EPA Pesticide Factsheets

    Background. New Bedford Harbor (NBH), located in southeastern Massachusetts, was designated as a marine Superfund site in 1983 due to sediment contamination by polychlorinated biphenyls (PCBs). Based on risks to human health and the environment, the first two phases of the site cleanup involved dredging PCB-contaminated sediments from the harbor. Therefore, a long-term monitoring program (LTM) was developed to measure spatial and temporal chemical and biological changes in sediment, water, and biota to assess the effects and effectiveness of the remedial activities. Approach. A systematic, probabilistic sampling design was used to select approximately 70 sediment sampling stations. Sediment was collected at each station and chemical (e.g., PCBs, metals), physical (e.g., grain size), and biological (e.g., benthic community) measurements were conducted on all samples. There have been six sample collections to date: 1993-baseline, 1995-post hot spot removal, 1999-prior to full scale dredging, and then at 5 year intervals: 2004, 2009, and 2014. Mussel (Mytilus edulis) bioaccumulation has also been measured twice yearly. Results. There is a decreasing spatial gradient in sediment PCB concentrations from the northern boundary (upper harbor) to the southern boundary (outer harbor) of the site. Along this same transect, there is an increase in biological condition (e.g., benthic community diversity). Temporally, the contaminant and biological gradients have been

The ROD is a public document signed by the appropriate Regional Administrator which details cleanup, cost estimates, and EPA`s responsiveness to the public comment summary. The ROD may be litigated, thus it is important to have all current updates to the signed EPA decision. The ROD may be amended with an Amendment or supplemented by an Explanation of Significant Difference (ESD). A Superfund Site may have multiple RODs, as each Superfund Site may be further redefined as Operable Units and Events. This allows EPA`s decisions to evolve as new technology presents itself. Average clean-up time for a Superfund Site can range from 12 to 100 years.

    Pavetto, C.S.; Rubinton, D.S.

    1994-12-31

    The need for cleaning up hazardous waste disposal sites was identified early in New York. In fact, New York`s ``Superfund`` statute preceded the federal Superfund law thereby providing a model for CERCLA. Moreover, there are currently almost as many sites on New York`s Registry of Inactive Hazardous Waste Disposal sites as there are sites on the National Priorities List. While New York`s law served as a model for the federal CERCLA, CERCLA, in turn, has served as a model for other states` statutes. Similarly, lessons learned from the implementation of state Superfund statutes such as New York`s can be instructive for those whose work involves dealing with CERCLA-type issues. This is because the problems associated with site restoration and cleanup, such as exceedingly complex site review and evaluation processes, high transaction costs, and difficulties in prioritizing sites for clean-up based upon the threat or risk of environmental harm, are universal.

    Residents living in communities near Superfund sites have expressed concern that releases from these facilities affect their health, including adverse effects on their immune systems. We used data from six cross-sectional studies to evaluate whether people who live near several Superfund sites are more likely to have individual immunoglobulin test results (IgA, IgG, and IgM) below or above the reference range than those who live in comparison areas with no Superfund site. Study participants consisted of target-area residents who lived close to a Superfund site and comparison-area residents who were not located near any Superfund or hazardous waste sites. A consistent modeling strategy was used across studies to assess the magnitude of the relationship between area of residence and immunoglobulin test results, adjusting for potential confounders and effect modifiers. In all study areas, the results suggest that people who live near a Superfund site may have been more likely to have IgA test results above the reference range than comparison areas residents regardless of modeling strategy employed. The effect measures were larger for residents who lived in communities near military bases with groundwater contamination. For all analyses the wide confidence intervals reflect uncertainty in the magnitude of these effects. To adequately address the question of whether the immune system is affected by low-level exposures to hazardous substances, we recommend that more functional immunotoxicity tests be conducted in human populations where individual exposure information is available or when it can be reasonably estimated from environmental exposure measurements.

  11. RCRA/UST, Superfund, and EPCRA hotline training module. Introduction to statutory overview of CERCLA

    SciTech Connect

    1996-03-01

    This module presents a brief overview of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), the statute through which Congress established EPA`s hazardous substance release reporting and cleanup program, known as the `Superfund` program. The statute provides the legal authority and general framework for the program, while specific procedural requirements can be found in the regulations and guidance documents. It is vital that Hotline Information Specialist be knowledgeable about the statute itself because it is the primary reference used to answer questions relating to the Superfund program. This module presents information on the CERCLA statute only, not the regulations promulgated pursuant to the statute.

    1991-12-01

    Several small systems and individual homeowners have been faced with the task of treating their groundwater that has been contaminated with various organic contaminants. Contamination is such that the locations described in this presentation have been designated Federal Superfund sites undergoing emergency or remedial actions. These sites have utilized point-of-entry water treatment devices to treat their groundwater. The devices used include: single and dual granular activated carbon (GAC) columns; air stripping in series with GAC; and ozone/UV followed by GAC. Cost (capital and operating) contaminant removal performance, GAC breakthrough and disinfection byproduct formation will be discussed for several Superfund or state led cleanup actions.

  14. An evaluation of public preferences for Superfund site cleanup

    SciTech Connect

    Schulze, W.

    1995-12-31

    This study evaluates public preferences for cleanup of NPL sites. The National Priority List (NPL) was created to allocate use of Superfund monies. In spite of the expert view that NPL sites pose little immediate threat, substantial evidence suggests that people living near such sites believe they are at risk. The seriousness of the public view is captured by the large losses in property values that have occurred near such sites. Complete sit cleanup would presumably restore property values, thus property losses can approximate public willingness to pay for complete cleanup. Since complete cleanup is extremely expensive, a key question is, what level of cleanup would be acceptable to the public? A pilot market research study was used in an attempt to develop a methodology to answer this question. A survey instrument was developed that presented a hypothetical NPL site with a large population in close proximity, informed respondents of expert assessments of risk and the potential environmental effects of the site, and provided detailed information on cleanup options. Respondents selected their most preferred option. Implications of the research were further explored by examining potential aggregate benefits for cleanup of non-Federal NPL sites. Some preliminary conclusions emerged. (1) NPL listing of a site appears to exacerbate the fears of nearby citizens. (2) Results suggest that many people are satisfied with options other than complete cleanup, particularly when there are risks associated with complete cleanup. (3) Values for cleanup estimated in the pilot study are consistent with estimates from property value evidence. (4) High priority should be placed on expedited cleanup of sites with large enough nearby populations to pass a benefit-cost test based on public preferences. (5) Public preferrences should be incorporated into decisions regarding the extent of cleanup at NPL sites.

  15. Fate and Transport of Perchlorate at California's Stringfellow Superfund Site

    Geologic conditions exert primary control over the fate and transport of perchlorate at the Stringfellow Superfund site. A buried valley filled with alluvium has been defined that extends from Pyrite Canyon, location of the former Stringfellow acid pits, down to near the Santa Ana River. The buried valley is cut into the underlying granitic bedrock, and appears to be a paleo-channel of the ancestral Pyrite Creek. The groundwater hydraulic gradient aligns closely with the buried valley, as does the perchlorate plume. The buried valley appears to be a preferential pathway for contaminant migration. Perchlorate concentrations in the downgradient portion of the plume have been slowly decreasing over time, suggesting that the groundwater extraction wells are effective at cutting off the source. Perchlorate degradation, however, appears to be minimal over most of the sandy aerobic aquifer, as concentrations of perchlorate persist over a 5-mile long plume. Scattered concentrations of perchlorate in the 1 to 12 ug/L range are widespread over a broad area adjacent to the plume and appear to be unrelated to the plume. Hydrogeologic analysis and perchlorate isotope analysis are being used to investigate whether these outlying concentrations may be related to the historic use of perchlorate- bearing mineral nitrate fertilizer. At the distal end of the plume, a marked change in the fate of perchlorate occurs beneath the Santa Ana River. Sampling of mini-piezometers installed into the river sediments shows that the perchlorate and nitrate concentrations fall to below detection as the aquifer environment changes from oxidizing to reducing conditions. In this local environment, it appears that anaerobic biodegradation reduces the perchlorate and nitrate. As a result of degradation of perchlorate, and possibly mixing of infiltrating river water beneath the losing portions of the river, perchlorate concentrations decrease to below 6 ug/L downgradient of the river.

  16. Mechanisms of toxicity/carcinogenicity and Superfund decisions.

    PubMed Central

    LaVelle, J M

    1991-01-01

    Heavy metals that contaminate soils and water usually exist in various oxidation states and form a number of compounds with different physical and chemical characteristics. These differences are often reflected in dramatic variation in toxicokinetic and biologic properties. Such variation in properties, critical in determining intrinsic toxicity, often causes a great deal of uncertainty in analyses of public health risks at sites where metal exposure is evaluated. In the Superfund program, such uncertainties may substantially undermine attempts to characterize potential impacts to populations exposed to metals from improperly disposed waste. In the case of chromium, risk assessment uncertainties can be considerable and fall generally into two categories. First, there is almost no information on potential health effects due to chronic oral exposure to chromium-containing compounds, and a nonquantifiable and probably large uncertainty exists in establishing no-effect levels. In fact, reference doses (RfDs) for CrIII and CrVI are based on chronic studies in which no adverse effects were seen even at the highest dose. Considerations of bioavailability, deduced from site characterization data, and acute toxicity indicate that general application of these RfDs may lead to highly inaccurate estimations of risk. Second, because of the ready reduction of CrVI in biological systems, it has not been possible to separate effects of CrVI from those of CrIII. Thus, data on the relative toxicity and carcinogenicity of these two species is sparse and difficult to interpret. Moreover, kinetic considerations make it difficult to determine the site and rates of reduction of CrVI. This makes prediction of target site concentrations of the two species difficult.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1935841

    Assessing human exposure to chemicals from Superfund sites requires knowledge of basic physical, chemical, and biological processes occurring in the environment and specific information about the local environment and population in the vicinity of sites of interest. Although progress is being made in both areas, there is still a tremendous amount to be done. Participants at this meeting have identified several of the areas in need of greater understanding, and they are listed below. Movement of dissolved and volatile organics, especially NAPLs, in the subsurface environment. This includes study of the partitioning of compounds between NAPLs, air, water, and soil. Partitioning of volatilized chemicals between gaseous and aerosol components of the atmosphere. This includes understanding how these components influence both wet and dry deposition. Long-term movement from sediments into biota and how these affect chronic toxicity to sediment biota. Broad validation of PBPK models describing partitioning of compounds from sediment and water into fish. Reactions of chemicals sorbed to atmospheric particles. This includes application of laboratory models to real and varied atmospheric conditions. Interactions between biotic and abiotic transformations in soil and sediment. Applicability of physiological pharmacokinetic models developed in laboratory studies of experimental animals and clinical investigations of humans to environmental chemicals, concentrations, and routes of exposure in humans. Use of human and wildlife behavioral and biomonitoring information to estimate exposure. This includes better understanding of human variability and the applicability of information gathered from particular wildlife species. To successfully address these gaps in our knowledge, much more analytical data must be collected.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8187712

    1995-12-31

    The Benfield Industries, Inc. Superfund site located in Hazelwood, North Carolina has been found to have approximately 15,000 cubic yards of polycyclic aromatic hydrocarbon (PAH) contaminated soil. Risk based clean up goals were specified at the site for eight target PAH compounds including benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, indeno(1,2,3-cd)pyrene, naphthalene, and pentachlorophenol. Treatability studies were performed to evaluate solid phase bioremediation, which includes ex-situ and in-situ land treatment processes, for treatment of the site soil. All treatments were conducted using only indigenous microorganisms maintained under aerobic conditions. Two soil samples with different levels of PAH contamination were collected from the site for use in the treatability evaluations. The two soil samples were contaminated with total PAHs at concentrations of approximately 30 milligrams per kilogram (mg/kg) and 6,000 mg/kg, respectively. Three solid phase bioremediation studies were conducted over a one and one half year period using starting concentrations of total PAHs of approximately 30; 600; and 6,000 mg/kg. The objectives of the studies included determining (1) if clean up goals could be achieved, (2) the approximate biodegradation rate of PAHs in the site soils, and (3) the optimum environmental conditions for biodegradation of the PAHs. Some of the environmental parameters which were varied during the testing included moisture levels, soil conditioners, nutrients and pH. The results of the testing indicated that total and target PAHs can be reduced by up to 90 percent in less than 50 days, depending on environmental conditions maintained in the reactors. Clean up goals for all of the target compounds were achieved at some point during the study.

    Tillman, Fred D

    2010-01-01

    Extensive groundwater contamination resulting from industrial activities led to the listing of the Tucson International Airport Area as a Superfund Site in 1983. Early investigations revealed elevated levels of volatile organic compounds (VOCs) including the chlorinated solvents trichloroethylene (TCE) and perchloroethylene (PCE) in wells in the area. Several responsible parties were identified and cleanup activities were begun in the late 1980s using technology designed for removal of VOCs. In 2002, the compound 1,4-dioxane was discovered in wells in the Tucson Airport Remediation Project (TARP) area. Since then, 1,4-dioxane has been detected throughout the TARP area, in some cases exceeding the U.S. Environmental Protection Agency (USEPA) drinking water advisory level of 3 ?g/L.

    This treatability study was conducted by Pacific Northwest National Laboratory (PNNL), at the request of the U. S. Environmental Protection Agency (EPA) Region 2, to evaluate the feasibility of using in situ treatment technologies for chromate reduction and immobilization at the Puchack Well Field Superfund Site in Pennsauken Township, New Jersey. In addition to in situ reductive treatments, which included the evaluation of both abiotic and biotic reduction of Puchack aquifer sediments, natural attenuation mechanisms were evaluated (i.e., chromate adsorption and reduction). Chromate exhibited typical anionic adsorption behavior, with greater adsorption at lower pH, at lower chromate concentration, and at lower concentrations of other competing anions. In particular, sulfate (at 50 mg/L) suppressed chromate adsorption by up to 50%. Chromate adsorption was not influenced by inorganic colloids.

    The data contained in this report are a compilation of selected water- and sediment-quality, aquatic biology, and mine-waste data collected at the Ely Copper Mine Superfund site in Vershire, VT, from August 1998 through May 2007. The Ely Copper Mine Superfund site is in eastern, central Vermont (fig. 1) within the Vermont Copper Belt (Hammarstrom and others, 2001). The Ely Copper Mine site was placed on the U.S. Environmental Protection Agency (USEPA) National Priorities List in 2001. Previous investigations conducted at the site documented that the mine is contributing metals and highly acidic waters to local streams (Hammarstrom and others, 2001; Holmes and others, 2002; Piatak and others, 2003, 2004, and 2006). The U.S. Geological Survey (USGS), in cooperation with the USEPA, compiled selected data from previous investigations into uniform datasets that will be used to help characterize the extent of contamination at the mine. The data may be used to determine the magnitude of biological impacts from the contamination and in the development of remediation activities. This report contains analytical data for samples collected from 98 stream locations, 6 pond locations, 21 surface-water seeps, and 29 mine-waste locations. The 98 stream locations are within 3 streams and their tributaries. Ely Brook flows directly through the Ely Copper Mine then into Schoolhouse Brook (fig. 2), which joins the Ompompanoosuc River (fig. 1). The six pond locations are along Ely Brook Tributary 2 (fig. 2). The surface-water seeps and mine-waste locations are near the headwaters of Ely Brook (fig. 2 and fig. 3). The datasets 'Site_Directory' and 'Coordinates' contain specific information about each of the sample locations including stream name, number of meters from the mouth of stream, geographic coordinates, types of samples collected (matrix of sample), and the figure on which the sample location is depicted.

    Currently, there is an effort under way to encourage remedial project managers at contaminated sites to use passive sampling to collect freely dissolved concentrations (Cfree ) of hydrophobic organic contaminants to improve site assessments. The objective of the present study was to evaluate the use of passive sampling for measuring water column Cfree for several hydrophobic organic contaminants at 3 US Environmental Protection Agency Superfund sites. Sites investigated included New Bedford Harbor (New Bedford, MA, USA), Palos Verdes Shelf (Los Angeles, CA, USA), and Naval Station Newport (Newport, RI, USA); and the passive samplers evaluated were polyethylene, polydimethylsiloxane-coated solid-phase microextraction fibers, semipermeable membrane devices, and polyoxymethylene. In general, the different passive samplers demonstrated good agreement, with Cfree values varying by a factor of 2 to 3. Further, at New Bedford Harbor, where conventional water sample concentrations were also measured (i.e., grab samples), passive sampler-based Cfree values agreed within a factor of 2. These findings suggest that all of the samplers were experiencing and measuring similar Cfree during their respective deployments. Also, at New Bedford Harbor, a strong log-linear, correlative, and predictive relationship was found between polyethylene passive sampler accumulation and lipid-normalized blue mussel bioaccumulation of polychlorinated biphenyls (r(2)  = 0.92, p < 0.05). The present study demonstrates the utility of passive sampling for generating scientifically accurate water column Cfree values, which is critical for making informed environmental management decisions at contaminated sediment sites.

    2002-11-01

    Microtechniques for polycyclic aromatic hydrocarbon (PAH) body burden and total lipid analysis were developed and applied to determine the first lipid-normalized bioaccumulation factors for a hydrophobic organic toxicant in a meiobenthic organism (0.063-0.500 mm) living in field-contaminated sediments. The total lipid microtechnique combines the standard Bligh-Dyer extraction method with a colorimetric quantification method for analysis of samples containing I to 50 microg lipid. The microtechnique for body burden analysis quantifies PAHs from tissue samples containing as little as 10 pg PAH. Fluoranthene, benz[a]anthracene, and benzo[a]pyrene biota-sediment accumulation factors (BSAFs) were determined for the meiobenthic copepod Microarthridion littorale living in an estuarine U.S. Environmental Protection Agency Superfund site. Gravid female, nongravid female, and male BSAFs were 0.82, 0.54, and 0.36, respectively, for fluoranthene; 0.50, 0.44, and 0.40, respectively, for benz[a]anthracene; and 0.09, 0.12, and 0.15, respectively, for benzo[a]pyrene. Comparison of nonlipid-normalized bioaccumulation factors (BAFs) to BSAFs indicates that M. littorale bioaccumulated PAHs on a gram lipid basis. The BSAFs declined consistently with increasing PAH log K(ow) for all copepod sex and reproductive stages. Sex- and stage-specific comparisons of BSAFs suggest that differences in lipid content and quality may lead to differences in BSAF values depending on PAH molecular weight and/or hydrophobicity.

    The NIEHS funds several basic and applied research programs, many of which also require research translation or outreach. This paper reports on a project by the Brown University Superfund Basic Research Program (SBRP), in which outreach and research translation teams collaborated with state regulatory agency personnel and community activists on a legislative initiative to mitigate the financial impacts of living in a contaminated community. The Environmentally Compromised Home Ownership (ECHO) program makes home equity loans of up to $25,000 available to qualified applicants. This collaboration provides a case study in community engagement and demonstrates how research translation and outreach activities that are clearly differentiated yet well integrated can improve a suite of basic and applied research. Although engaging diverse constituencies can be difficult, community-engaged translation and outreach have the potential to make research findings more useful to communities, address some of the social impacts of contamination, and empower stakeholders to pursue their individual and collectively-held goals for remediation. The NIEHS has recently renewed its commitment to community-engaged research and advocacy, making this an optimal time to reflect on how basic research programs that engage stakeholders through research translation and outreach can add value to the overall research enterprise.

    This paper estimates the health costs at Superfund sites for conditions associated with volatile organic compounds (VOCs) in drinking water. Health conditions were identified from published literature and registry information as occurring at excess rates in VOC-exposed populations. These health conditions were: (1) some categories of birth defects, (2) urinary tract disorders, (3) diabetes, (4) eczema and skin conditions, (5) anemia, (6) speech and hearing impairments in children under 10 years of age, and (7) stroke. Excess rates were used to estimate the excess number of cases occurring among the total population living within one-half mile of 258 Superfund sites. These sites had evidence of completed human exposure pathways for VOCs in drinking water. For each type of medical condition, an individual`s expected medical costs, long-term care costs, and lost work time due to illness or premature mortality were estimated. Costs were calculated to be approximately $330 million per year, in the absence of any remediation or public health intervention programs. The results indicate the general magnitude of the economic burden associated with a limited number of contaminants at a portion of all Superfund sites, thus suggesting that the burden would be greater than that estimated in this study if all contaminants at all Superfund sites could be taken into account.

    In Berlin, New Hampshire, USA, the Androscoggin River flows adjacent to a former chlor-alkali facility that is a US Environmental Protection Agency Superfund site and source of mercury (Hg) to the river. The present study was conducted to determine the fate and bioaccumulation of methylmercury (MeHg) to lower trophic-level taxa in the river. Surface sediment directly adjacent to the source showed significantly elevated MeHg (10–40× increase, mean ± standard deviation [SD]: 20.1 ± 24.8 ng g–1 dry wt) and total mercury (THg; 10–30× increase, mean ± SD: 2045 ± 2669 ng g–1 dry wt) compared with all other reaches, with sediment THg and MeHg from downstream reaches elevated (3–7× on average) relative to the reference (THg mean ± SD: 33.5 ± 9.33 ng g–1 dry wt; MeHg mean ± SD: 0.52 ± 0.21 ng g–1 dry wt). Water column THg concentrations adjacent to the point source for both particulate (0.23 ng L–1) and dissolved (0.76 ng L–1) fractions were 5-fold higher than at the reference sites, and 2-fold to 5-fold higher than downstream. Methylmercury production potential of periphyton material was highest (2–9 ng g–1 d–1 dry wt) adjacent to the Superfund site; other reaches were close to or below reporting limits (0. 1 ng g–1 d–1 dry wt). Total Hg and MeHg bioaccumulation in fauna was variable across sites and taxa, with no clear spatial patterns downstream of the contamination source. Crayfish, mayflies, and shiners showed a weak positive relationship with porewater MeHg concentration.

  20. Nanotoxicology and nanotechnology: new findings from the NIEHS and Superfund Research Program scientific community.

    2014-01-01

    Nanomaterials are characterized by their small size (i.e., nanometer scale) and can be engineered from nearly any chemical substance, creating materials that differ in composition, particle size, shape, and surface coatings. These materials are often seen as a "double-edged sword" by having properties that make them potentially beneficial in product development, drug delivery, and remediation of hazardous substances, but these same properties may result in interaction with biological systems and potential effects in the environment. The National Institute of Environmental Health Sciences (NIEHS) is interested in both the potential risks associated with exposure to these materials, while harnessing the power of engineered nanomaterials to improve public health. This presentation will consist of discussion of nanoparticle studies by NIEHS researchers and the extramural community and its efforts to develop cross-agency initiatives to solve the many vexing issues associated with nanomaterials. For example, researchers from the NIEHS National Toxicology Program (NTP) are evaluating a number of nanomaterial classes in comprehensive toxicology studies. NIEHS also has an extensive extramural research grant portfolio consisting of the Nano Grand Opportunities (Nano GO) Program and NIEHS Centers for Nanotechnology Health Implications Research (NCNHIR) Consortium consisting of U19 and U01 Cooperative Centers. Furthermore, the NIEHS Superfund Research Program (SRP), which supports a network of university (P42, R01), small business (SBIR/STTR), and training grants (R25), provides funding to grantees evaluating the toxicology of nanomaterials, developing new or improved nanotechnologies to monitor and remediate hazardous substances, and training professionals in the use of these of materials. The NIEHS's Worker Education Branch also offers educational materials for training workers on risks of nanotechnology in laboratories, manufacturing facilities, at hazardous waste cleanup

  1. Analysis of geophysical logs, at North Penn Area 6 Superfund Site, Lansdale, Montgomery County, Pennsylvania

    USGS Publications Warehouse

    Conger, Randall W.

    1999-01-01

    The U.S. Geological Survey (USGS), as part of technical assistance to the U.S. Environmental Protection Agency (USEPA), collected borehole geophysical log data in 34 industrial, commercial, and public supply wells and 28 monitor wells at the North Penn Area 6 Superfund Site, in Lansdale, Pa., from August 22, 1995, through August 29, 1997. The wells range in depth from 50 to 1,027 feet below land surface and are drilled in Triassic-age shales and siltstones of the Brunswick Group and Lockatong Formation. The geophysical log data were collected to help describe the hydrogeologic framework in the area and to provide guidance in the reconstruction of the 28 monitor wells drilled during summer 1997. At the time of logging, all wells had open-hole construction. The geophysical logs, caliper, fluid-resistivity, and fluid-temperature, and borehole video logs were used to determine the vertical distribution of water-bearing fractures. Heatpulse-flowmeter measurements were used to determine vertical borehole flow under pumping and nonpumping conditions. The most productive fractures generally could be determined from heatpulse-flowmeter measurements under pumping conditions. Vertical borehole flow was measured under nonpumping conditions in most wells that had more than one water-bearing fracture. Upward flow was measured in 35 wells and probably is a result of natural head differences between fractures in the local ground-water-flow system. Downward flow was measured in 11 wells and commonly indicated differences in hydraulic heads of the fractures caused by nearby pumping. Both upward and downward flow was measured in three wells. No flow was detected in eight wells. Natural-gamma-ray logs were used to estimate the attitude of bedding. Thin shale marker beds, shown as spikes of elevated radioactivity in the natural-gamma logs of some wells throughout the area, enable the determination of bedding-plane orientation from three-point correlations. Generally, the marker beds in

    2011-01-01

    The former Chlor-Alkali Facility in Berlin, New Hampshire, was listed on the U.S. Environmental Protection Agency National Priorities List in 2005 as a Superfund site. The Chlor-Alkali Facility lies on the east bank of the Androscoggin River. Elemental mercury currently discharges from that bank into the Androscoggin River. The nature, extent, and the speciation of mercury and the production of methyl mercury contamination in the adjacent Androscoggin River is the subject of continuing investigations. The U.S. Geological Survey, in cooperation with Region I of the U.S. Environmental Protection Agency, used geophysical methods to determine the distribution, thickness, and physical properties of sediments in the Androscoggin River channel at a small area of an upstream reference reach and downstream from the site to the New Hampshire–Maine State border. Separate reaches of the Androscoggin River in the study area were surveyed with surface geophysical methods including ground-penetrating radar and step-frequency electromagnetics. Results were processed to assess sediment characteristics including grain size, electrical conductivity, and pore-water specific conductance. Specific conductance measured during surface- and pore-water sampling was used to help interpret the results of the geophysical surveys. The electrical resistivity of sediment samples was measured in the laboratory with intact pore water for comparison with survey results. In some instances, anthropogenic features and land uses, such as roads and power lines affected the detection of riverbed properties using geophysical methods; when this occurred, the data were removed. Through combining results, detailed riverbed sediment characterizations were made. Results from ground-penetrating radar surveys were used to image and measure the depth to the riverbed, depth to buried riverbeds, riverbed thickness and to interpret material-type variations in terms of relative grain size. Fifty two percent of the

Also, in 1998-1999 we monitored nest boxes at Grove Pond and Plow Shop Pond at a U.S. Environmental Protection Agency Superfund site in Ayer, MA. We recorded breeding success at all locations. On average among locations, total mercury (THg) biomagnified 2 to 4-fold from food to eggs and 9 to 18-fold from food to feathers. These are minimum values because the proportion of transferable methyl mercury (MeHg) of the THg in insects varies (i.e., 35%-95% of THg) in food boluses. THg was highest in food boluses at Aunt Betty Pond at Acadia, whereas THg in eggs was highest at the Superfund site. A few eggs from nests at each of these locations exceeded the threshold (i.e., 800-1,000 ng/g, wet wt.) of embryotoxicity established for Hg. Hatching success was 88.9% to 100% among locations, but five eggs failed to hatch from 4 of the 11 clutches in which an egg exceeded this threshold. MeHg in feathers was highest in tree swallows at Aunt Betty Pond and the concentration of THg in bodies was related to the concentration in feathers. Transfer of an average of 80%-92% of the Hg in bodies to feathers may have enhanced nestling survival. Residues of Hg in tissues of tree swallows in the Northeast seem higher than those of the Midwest.

    An extensive site-characterization project was conducted at a large chlorinated-solvent contaminated Superfund site in Tucson, AZ. The project consisted of several components, including traditional site-characterization activities, tracer tests, laboratory experiments conducted with core material collected from the site, and mathematical modeling. The primary focus of the work presented herein is the analysis of induced-gradient contaminant elution tests conducted in a source zone at the site, investigation of the potential occurrence of immiscible liquid in the saturated zone, characterization of the relationship between mass flux reduction and mass removal, and evaluation of the impact of source-zone management on site remediation. The results of the present study, along with those of prior work, indicate that immiscible liquid is likely present in the saturated zone at the site source zones. Extensive tailing and rebound was observed for the contaminant-elution tests, indicating nonideal transport and mass-transfer behavior. The elution data were analyzed with a source-zone-scale mathematical model, and the results indicated that nonideal immiscible-liquid dissolution was the primary cause of the observed behavior. The time-continuous relationship between mass flux reduction and mass removal associated with the plume-scale pump-and-treat operation exhibited an initial large drop in mass flux with minimal mass removed, followed by a period of minimal mass flux reduction and a second period of large reduction. This behavior reflects the impact of both source-zone and aqueous-plume mass removal dynamics. Ultimately, a greater than 90% reduction in mass flux was achieved for a mass removal of approximately 50%. The influence of source-zone management on site remediation was evaluated by conducting two predictive simulations, one for which the source zones were controlled and one for which they were not.

    The Escambia Wood Treating Company (ETC) Superfund site, Pensacola, FL, is contaminated with polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F), benzo(a)pyrene, lead and arsenic from pentachlorophenol (PCP), creosote, and other compounds used to treat utility poles and foundation pilings. Although ETC's operations ceased in 1982, soils in the areas surrounding the facility continue to exhibit elevated levels of contaminants attributable to ETC operations. In July 2000, individuals who may have been affected by contamination from the ETC site, including current and former residents and former workers and their household members were invited to participate in a study, which included a health and exposure history and routine blood analysis. We also conducted a toxicological health evaluation of a subset of these eligible workers/residents by analyzing serum levels of 17 PCDD/F congeners. Members of the ETC cohort exhibited elevated serum PCDD/F relative to the general population, and congener profiles in members of the cohort reflected patterns commonly observed in persons exposed to PCP. Hypertension prevalence in the cohort was found to correlate with PCDD/F levels, although no other significant relationships were identified with monitored health indices.

    The hydrology and quality of surface water in and around the Pike Hill Brook watershed, in Corinth, Vermont, was studied from October 2004 to December 2005 by the U.S. Geological Survey in cooperation with the U.S. Environmental Protection Agency (USEPA). Pike Hill was mined intermittently for copper from 1847 to 1919 and the site is known to be contributing trace elements and acidity to Pike Hill Brook and an unnamed tributary to Cookville Brook. The site has been listed as a Superfund site since 2004. Streamflow, specific conductance, pH, and water temperature were measured continuously and monthly at three sites on Pike Hill Brook to determine the variation in these parameters over an annual cycle. Synoptic water-quality sampling was done at 10 stream sites in October 2004, April 2005, and June 2005 and at 13 stream sites in August 2005 to characterize the quality of surface water in the watershed on a seasonal and spatial basis, as well as to assess the effects of wetlands on water quality. Samples for analysis of benthic macroinvertebrate populations were collected at 11 stream sites in August 2005. Water samples were analyzed for 5 major ions and 32 trace elements. Concentrations of trace elements at sites in the Pike Hill Brook watershed exceeded USEPA National Recommended Water Quality Criteria acute and chronic toxicity standards for aluminum, iron, cadmium, copper, and zinc. Concentrations of copper exceeded the chronic criteria in an unnamed tributary to Cookville Brook in one sample. Concentrations of sulfate, calcium, aluminum, iron, cadmium, copper, and zinc decreased with distance from a site directly downstream from the mine (site 1), as a result of dilution and through sorption and precipitation of the trace elements. Maximum concentrations of aluminum, iron, cadmium, copper, and zinc were observed during spring snowmelt. Concentrations of sulfate, calcium, cadmium, copper, and zinc, and instantaneous loads of calcium and aluminum were

    This Explanation of Significant Differences (ESD) is for the Refuse Hideaway Landfill Superfund site in Middleton, Wisconsin. The June 28, 1995 ROD required groundwater extraction and treatment of the most highly contaminated groundwater (greater than 200 ppb total volatile organic compounds (VOCs)), treatment of groundwater to discharge standards and injection of the treated water into the aquifer upgradient of the landfill to stimulate in-situ biodegradation of the degradable components of the contamination. This ESD documents that US EPA, in consultation with WDNR, has determined, based on the 1998 groundwater data, that it is not necessary to implement the groundwater extraction and treatment component of the selected remedy. The significant decrease of total VOCs in groundwater over a short period of time indicates that groundwater should meet the remedial action objective of NR 140 PALs within a reasonable period of time if source control measures continue to be operated and maintained.

  7. Biomonitoring for metal contamination near two Superfund sites in Woburn, Massachusetts, using phytochelatins.

    2004-09-01

    Characterizing the spatial extent of groundwater metal contamination traditionally requires installing sampling wells, an expensive and time-consuming process in urban areas. Moreover, extrapolating biotic effects from metal concentrations alone is problematic, making ecological risk assessment difficult. Our study is the first to examine the use of phytochelatin measurements in tree leaves for delimiting biological metal stress in shallow, metal-contaminated groundwater systems. Three tree species (Rhamnus frangula, Acer platanoides, and Betula populifolia) growing above the shallow groundwater aquifer of the Aberjona River watershed in Woburn, Massachusetts, display a pattern of phytochelatin production consistent with known sources of metal contamination and groundwater flow direction near the Industri-Plex Superfund site. Results also suggest the existence of a second area of contaminated groundwater and elevated metal stress near the Wells G&H Superfund site downstream, in agreement with a recent EPA ecological risk assessment. Possible contamination pathways at this site are discussed.

    The research presented here weighs the ability of two major explanations of social inequality-Massey and Denton's racial segregation explanation and Wilson's emphasis on economic deprivation (concentrated poverty)-to predict environmental inequality. Two sets of logistic regression analyses are used to predict the location of Superfund sites in Portland, Oregon and Detroit, Michigan providing a conditional understanding of environmental inequality within a larger sociological context. The analysis includes a general examination of the two theories in all census tracts in both cities and a set of analyses focusing upon Black neighborhoods in Detroit. The findings indicate that there is support for explanations of environmental inequality that include both racial segregation and economic deprivation, but that the more powerful of the two is economic deprivation. The results suggest that even though African-American neighborhoods disproportionately house Superfund sites, these facilities are more likely to be located in Black neighborhoods that are economically deprived.

  9. Superfund expenditures and cleanup priorities: Distributive politics or the public interest

    Using data on all final National Priorities List (NPL) sites, this study employs an integrated model of distributive and public interest politics to determine whether the overall pace of cleanup efforts and funding of the $8.5 billion Superfund program over the past eight years reflects self-interested congressional influence or public interest objectives. Despite the fact that both EPA and Congress have substantial incentives to promote the Superfund program, the results indicate that once a site is on the final NPL, there is lettle committee-based congressional influence over the distribution of site cleanup or funding, although evidence exists that legislators can hasten a site's transition from proposed to final status on the NPL. The chief determinants of cleanup pace and level of funding are the site's Hazard Ranking System (HRS) scores, whether federal funds are financing the cleanup, and whether the site is designated as a state priority.

    We assessed determinants of cord serum polychlorinated biphenyl (PCB) levels among 720 infants born between 1993 and 1998 to mothers living near a PCB-contaminated Superfund site in Massachusetts, measuring the sum of 51 PCB congeners (capital sigmaPCB) and ascertaining maternal address, diet, sociodemographics, and exposure risk factors. Addresses were geocoded to obtain distance to the Superfund site and neighborhood characteristics. We modeled log10(capital sigmaPCB) as a function of potential individual and neighborhood risk factors, mapping model residuals to assess spatial correlates of PCB exposure. Similar analyses were performed for light (mono-tetra) and heavy (penta-deca) PCBs to assess potential differences in exposure pathways as a function of relative volatility. PCB-118 (relatively prevalent in site sediments and cord serum) was assessed separately. The geometric mean of capital sigmaPCB levels was 0.40 (range, 0.068-18.14) ng/g serum. Maternal age and birthplace were the strongest predictors of capital sigmaPCB levels. Maternal consumption of organ meat and local dairy products was associated with higher and smoking and previous lactation with lower capital sigmaPCB levels. Infants born later in the study had lower capital sigmaPCB levels, likely due to temporal declines in exposure and site remediation in 1994-1995. No association was found between capital sigmaPCB levels and residential distance from the Superfund site. Similar results were found with light and heavy PCBs and PCB-118. Previously reported demographic (age) and other (lactation, smoking, diet) correlates of PCB exposure, as well as local factors (consumption of local dairy products and Superfund site dredging) but not residential proximity to the site, were important determinants of cord serum PCB levels in the study community.

    2014-01-01

    Urban rivers with a history of industrial use can exhibit spatial and temporal variations in contaminant concentrations that may significantly affect risk evaluations and even the assessment of remediation efforts. Concentrations of 15 biologically available priority pollutant polycyclic aromatic hydrocarbons (PAHs) were measured over five years along 18.5 miles of the lower Willamette River using passive sampling devices and HPLC. The study area includes the Portland Harbor Superfund megasite with several PAH sources including remediation operations for coal tar at RM 6.3 west and an additional Superfund site, McCormick and Baxter, at RM 7 east consisting largely of creosote contamination. Study results show that organoclay capping at the McCormick and Baxter Superfund Site reduced PAHs from a pre-cap average of 440 ± 422 ng/L to 8 ± 3 ng/L post-capping. Results also reveal that dredging of submerged coal tar nearly tripled nearby freely dissolved PAH concentrations. For apportioning sources, fluoranthene/ pyrene and phenanthrene/anthracene diagnostic ratios from passive sampling devices were established for creosote and coal tar contamination and compared to published sediment values.

    2001-05-25

    In 1995, the discovery of leg malformations in several screech owl (Otis asio) nestlings and in their female parent at a Department of Energy (DOE) Superfund site in South Carolina prompted an investigation into the nature of the observed abnormalities. Surviving nestlings and the female parent were transferred to a captive screech owl breeding colony at the USGS Patuxent Wildlife Research Center, Laurel, MD. The malformed female parent and her offspring were each mated with normal owls from the colony for 3 yr. Matings of the malfored female produced five malformed and six normal owls; all owls produced by matings of normal offspring were normal. Malformed offspring were euthanized when it became apparent that their physical distress precluded survival under normal conditions of colony care. Euthanized owls were necropsied and examined for skeletal development. Detailed descriptions of eight malformed owls are presented. Results of the matings indicated that the leg mafformations were caused by a genetic trait in the female parent that was heterozygous dominant. The characteristic was lethal except in occasional mild manifestations and resembled an extreme form of a dominant abnormality previously described for domestic fowl called duplicate polydactyly. Other reports of skeletal abnormalities in wild birds and potential environmental causes of genetic mutations at the DOE Superfund site are presented. Other studies performed at the DOE Superfund site do not implicate elevated (above background) ionizing radiation from 137Cs, the dominant radionuclide where the owls were captured, as the cause of the mutation. The cause of this genetic abnormality remains unknown.

    1996-12-31

    An electrochemical peroxidation (ECP) process has been developed and used to degrade polychlorinated biphenyls (PCB) and volatile organic compounds (VOC)-contaminated water, sludge, and sediments at a New York State Federal and State Superfund Site. The process involves passing an oscillating low-amperage (<10 amps) current through steel electrodes immersed in an acidified water or sediment slurry into which hydrogen peroxide (<1,000 ppm) is added. The generated free radicals attack organic compounds, including organo-metallic complexes and refractory compounds including PCBs. PCB degradation ranged from about 30% to 80% in experiments involving Federal Superfund Site sediments; total PCBs were reduced by {approximately}97% to 68%, respectively, in water and slurry collected from a State Superfund subsurface storage tank. VOC bench-scale experiments involved chloroethane, 1,1-dichloroethane, dichloromethane, 1,1,1-trichloroethane, and acetone and after a 3-min ECP treatment, degradation ranged from >94% to about 99.9%. Results indicate the ECP is a viable process to degrade organic contaminants in water and sediment suspensions. Because the treated water suspensions are acidified, select trace metal sorbed to the particulates is solubilized and therefore can be segregated from the particulates, offering a process that simultaneously degrades organic contaminants and separates trace metals. 19 refs., 1 fig., 4 tabs.

  3. Air quality monitoring data could help lower emissions during Superfund cleanups

    1994-05-01

    Many Superfund projects include extensive air quality monitoring efforts. However, even when large volumes of air quality and meteorological data are collected, they often are used mainly for documentation, rather than as interactive tools to protect the public. This need not be so. If remedial actions were designed to include routine data evaluations and contingency plans to reduce emissions when action levels are exceeded, air quality monitoring could help minimize public exposure to hazardous air pollutants (HAPs) during cleanups. This article describes ambient air quality and meteorological monitoring programs conducted by URS Consultants Inc. (Denver) at the Sand Creek Industrial Superfund site in Commerce City, Colo., and the Vertac Chemical Co. Superfund site in Jacksonville, Ark. The Sand Creek project includes structure demolition, excavation and removal of soils and demolition debris, soil-vapor extraction of HAPs, and soil thermal treatment to remove pesticides and other hazardous organics. A rotary-kiln incinerator is used on the Vertac project to destroy solvents, pesticides, and other dioxin- and furan-contaminated materials.

    The Lava Cap Mine is located about 6 km east of the city of Grass Valley, Nevada County, California, at an elevation of about 900 m. Gold was hosted in quartz-carbonate veins typical of the Sierran Gold Belt, but the gold grain size was smaller and the abundance of sulfide minerals higher than in typical deposits. The vein system was discovered in 1860, but production was sporadic until the 1930s when two smaller operations on the site were consolidated, a flotation mill was built, and a 100-foot deep adit was driven to facilitate drainage and removal of water from the mine workings, which extended to 366 m. Peak production at the Lava Cap occurred between 1934 and 1943, when about 90,000 tons of ore per year were processed. To facilitate removal of the gold and accessory sulfide minerals, the ore was crushed to a very fine sand or silt grain size for processing. Mining operations at Lava Cap ceased in June 1943 due to War Production Board Order L-208 and did not resume after the end of World War II. Two tailings retention structures were built at the Lava Cap Mine. The first was a log dam located about 0.4 km below the flotation mill on Little Clipper Creek, and the second, built in 1938, was a larger earth fill and rip-rap structure constructed about 2 km downstream, which formed the water body now called Lost Lake. The log dam failed during a storm that began on December 31, 1996, and continued into January 1997; an estimated 8,000-10,000 m3 of tailings were released into Little Clipper Creek during this event. Most of the fine tailings were deposited in Lost Lake, dramatically increasing its turbidity and resulting in a temporary 1-1.5 m rise in lake level due to debris blocking the dam spillway. When the blockage was cleared, the lake level quickly lowered, leaving a ?bathtub ring? of very fine tailings deposited substantially above the water line. The U.S. Environmental Protection Agency (EPA) initiated emergency action in late 1997 at the mine site to reduce

    The decision document presents the selected remedy for the Northwest Tansformer South Harkness Street Site in Everson, Washington. The selected remedy under CERCLA authority is no further action. In order to verify that groundwater in the vicinity of the site remains uncontaminated now that response activities are complete, groundwater monitoring must continue until the CERCLA five-year review is performed, at which point EPA will determine whether continued monitoring is necessary.

    Ground water in the vicinity of several industrial facilities in Upper Gwynedd Township and Lansdale Borough, Montgomery County, Pa., is contaminated with several volatile organic compounds (VOCs). The 2-square-mile area was placed on the National Priorities List as the North Penn Area 7 Superfund Site by the U.S. Environmental Protection Agency (USEPA) in 1989. The U.S. Geological Survey (USGS) conducted geophysical logging, aquifer testing, water-level monitoring, and streamflow measurements in the vicinity of North Penn Area 7 from October 2002 through December 2006. This followed work that began in 2000 to assist the USEPA in developing an understanding of the hydrogeologic framework in the area as part of the USEPA Remedial Investigation. The study area is underlain by Triassic- and Jurassic-age sandstones, siltstones, and shales of the Lockatong Formation and the Brunswick Group. Regionally, these rocks strike northeast and dip to the northwest. The sequence of rocks form fractured-rock aquifers that act as a set of confined to semi-confined layered aquifers of differing permeabilities. The aquifers are recharged by precipitation and discharge to streams and wells. The Wissahickon Creek headwaters are less than 1 mile northeast of the study area. This stream flows southwest approximately parallel to strike and bisects North Penn Area 7. Ground water is pumped in the vicinity of North Penn Area 7 for industrial use and public supply. The USGS collected geophysical logs for 42 wells that ranged in depth from 40 to 477 ft. Aquifer-interval-isolation testing was done in 17 of the 42 wells, for a total of 122 zones tested. A multiple-well aquifer test was conducted by monitoring the response of 14 wells to pumping and shutdown of a 600-ft deep production well in November-December 2004. In addition, water levels were monitored continuously in four wells in the area from October 2002 through September 2006, and streamflow was measured quarterly at two sites on

    Arsenic is a contaminant at more than one-third of all Superfund Sites in the United States. Frequently this contamination appearsto resultfrom geochemical processes rather than the presence of a well-defined arsenic source. Here we examine the geochemical processes that regulate arsenic levels at the Coakley Landfill Superfund Site (NH), a site contaminated with As, Cr, Pb, Ni, Zn, and aromatic hydrocarbons. Long-term field observations indicate that the concentrations of most of these contaminants have diminished as a result of treatment by monitored natural attenuation begun in 1998; however, dissolved arsenic levels increased modestly over the same interval. We attribute this increase to the reductive release of arsenic associated with poorly crystalline iron hydroxides within a glaciomarine clay layer within the overburden underlying the former landfill. Anaerobic batch incubations that stimulated iron reduction in the glaciomarine clay released appreciable dissolved arsenic and iron. Field observations also suggest that iron reduction associated with biodegradation of organic waste are partly responsible for arsenic release; over the five-year study period since a cap was emplaced to prevent water flow through the site, decreases in groundwater dissolved benzene concentrations at the landfill are correlated with increases in dissolved arsenic concentrations, consistent with the microbial decomposition of both benzene and other organics, and reduction of arsenic-bearing iron oxides. Treatment of contaminated groundwater increasingly is based on stimulating natural biogeochemical processes to degrade the contaminants. These results indicate that reducing environments created within organic contaminant plumes may release arsenic. In fact, the strong correlation (>80%) between elevated arsenic levels and organic contamination in groundwater systems at Superfund Sites across the United States suggests that arsenic contamination caused by natural degradation of

    The Superfund Amendments and Reauthorization Act requires the use of remedial technologies that permanently and significantly reduce the volume, toxicity, or mobility of contaminated materials at affected sites. Extractive processes can accomplish the requirements of the Superfund Amendments and Reauthorization Act. Ethylenediaminetetraacetic acid (EDTA), N-2(acetamido)iminodiacetic acid (ADA), pyridine-2,6-dicarboxylic acid (PDA), and hydrochloric acid (HCl) were evaluated over a range of concentrations and reaction times in batch studies for their ability to remove lead (Pb) and cadmium (Cd) from a Superfund soil (Pb{sub total} = 65,200 mg/kg, Cd{sub total} = 52 mg/kg). Lead extraction was limited by a slow overall reaction. The order of Pb removal by extractant was EDTA > ADA > PDA > HCL. The soil was subjected to three repeated 1 h extractions in which a maximum of 86, 84, 70, and 54% of the total soil Pb was removed with EDTA, ADA, PDA, and HCl, respectively. The soil was not treated to below the Pb regulatory limit (1,000 mg/kg), even after five extractions with 0.075 M EDTA; however, the remaining Pb occurred in a residual form. All extractants treated the soil below the proposed Cd regulatory limit (40 mg/kg) within 1 h. With three repeated extractions EDTA, ADA, PDA, and HCl removed a maximum of 96, 100, 98, and 100% Cd, respectively. Lead recovery from spent solution was accomplished by hydroxide precipitation in the presence of excess calcium. Recovery at pH 11 was 70, 98, and 97% from the EDTA, ADA, and PDA complexes, respectively. The results indicate that the remediation of weathered, heavily Pb- and Cd-contaminated soils via extractive processes is possible under the appropriate conditions.

    In 1995, the discovery of leg malformations in several screech owl (Otis asio) nestlings and in their female parent at a Department of Energy (DOE) Superfund site in South Carolina prompted an investigation into the nature of the observed abnormalities. Surviving nestlings and the female parent were transferred to a captive screech owl breeding colony at the USGS Patuxent Wildlife Research Center, Laurel, MD. The malformed female parent and her offspring were each mated with normal owls from the colony for 3 yr. Matings of the malformed female produced five malformed and six normal owls; all owls produced by matings of normal offspring were normal. Malformed offspring were euthanized when it became apparent that their physical distress precluded survival under normal conditions of colony care. Euthanized owls were necropsied and examined for skeletal development. Detailed descriptions of eight malformed owls are presented. Results of the matings indicated that the leg malformations were caused by a genetic trait in the female parent that was heterozygous dominant. The characteristic was lethal except in occasional mild manifestations and resembled an extreme form of a dominant abnormality previously described for domestic fowl called duplicate polydactyly. Other reports of skeletal abnormalities in wild birds and potential environmental causes of genetic mutations at the DOE Super-fund site are presented. Other studies performed at the DOE Superfund site do not implicate elevated (above background) ionizing radiation from '37Cs, the dominant radio-nuclide where the owls were captured, as the cause of the mutation. The cause of this genetic abnormality remains unknown.

    This paper describes a prototype program initiated by U.S. EPA's Drinking Water Research Division (Cincinnati, Ohio), Region V Drinking Water Program (Chicago, Illinois), and Technology Evaluation Section (Edison, New Jersey) to inventory the types of drinking water related technology being applied at Superfund sites. Data from local utilities and State-funded sites were also included, accounting for nearly half the data collected at this time. Ground water as well as surface-water sites were inventoried. Future monitoring and research could focus on organic contaminants subject to variable influent and on other toxic wastes.

    Accumulation and effects of polychlorinated biphenyls (PCBs) in avian species were evaluated at a Superfund site located at Crab Orchard National Wildlife Refuge (IL, USA). European starlings (Sturnus vulgaris) were monitored at nest boxes constructed at each of two study and two reference sites. During the breeding season, starling productivity and adult provisioning behavior were monitored. At 15 d after hatch, chicks and adults were collected for contaminant and biomarker analyses. Chicks and adults were necropsied. ethoxyresorufin-O-deethylase (EROD) activity was measured in liver tissue, and polychlorinatedbiphenyl (PCB; Aroclor 1254) and 34 chlorinated biphenyl (CB) congener concentrations were measured in carcasses. Polychlorinated biphenyl and CB concentrations also were measured in eggs that failed to hatch. Mean Aroclor 1254 and quantified CB concentrations were greater (p < 0.001) in eggs that failed to hatch, 15-d-old chicks, and adults collected from PCB-contaminated sites (hereafter PCB sites) compared to those collected from reference sites. The EROD activity was greater (p = 0.005) in 15-d-old chicks, but not adults (p = 0.972), collected from PCB sites compared to those collected from reference sites. No differences were found among study and reference sites in number of eggs laid or percent of eggs hatched; however, reduced nest provisioning behavior and decreased chick survival were observed at PCB sites. Polychlorinated biphenyl concentrations measured in samples collected from the PCB sites are similar to concentrations previously associated with adverse effects in avian species. Other avian species utilizing these sites also may be exposed to PCBs with associated adverse effects. This study demonstrates that starling nestlings are good biological monitors of local contamination and continued monitoring may provide useful data for evaluating the effectiveness of proposed remediation.

    In polluted environments, when microbial aerosols originate locally, species composition of the aerosols should reflect the polluted source. To test the connection between local environmental pollution and microbial aerosols near an urban waterfront, we characterized bacterial aerosols at Newtown Creek (NTC), a public waterway and Superfund site in a densely populated area of New York, NY, USA. Culturable bacterial aerosol fallout rate and surface water bacterial concentrations were at least an order of magnitude greater at NTC than at a neighboring, less polluted waterfront and a nonurban coastal site in Maine. The NTC culturable bacterial aerosol community was significantly different in taxonomic structure from previous urban and coastal aerosol studies, particularly in relative abundances of Actinobacteria and Proteobacteria. Twenty-four percent of the operational taxonomic units in the NTC overall (air + water) bacterial isolate library were most similar to bacterial 16S rRNA gene sequences previously described in terrestrial or aquatic environments contaminated with sewage, hydrocarbons, heavy metals, and other industrial waste. This study is the first to examine the community composition and local deposition of bacterial aerosols from an aquatic Superfund site. The findings have important implications for the use of aeration remediation in polluted aquatic environments and suggest a novel pathway of microbial exposure in densely populated urban communities containing contaminated soil and water.

    The ACME Superfund site is one of many Superfund sites in Northern Illinois. This 20 acre (8.1 ha) site was contaminated by various volatile organic compounds (VOC's) and heavy metals during the 1960-1980s. To more fully understand the potential extent of the karst system and its interaction with contaminants, both surface and borehole geophysics including seismic refraction tomography, frequency domain electromagnetics, electrical resistivity, ground penetrating radar, as well as natural gamma and electromagnetic well logs, were undertaken over an approximately 3,000 square meter grid in a field immediately south of the ACME site. Seismic refraction tomography provided information on lithology and fluctuations in the bedrock surface in the depth range 6 to 8 m. Refraction, combined with electromagnetic conductivity, also allowed mapping of potential soil pipes and/or filled sinkholes in the overlying soils. These could channel surface waters into the karst conduit system. Frequency domain electromagnetics proved to be the most successful tool for the identifying possible karst conduits below the bedrock surface. Zones of reduced conductivity suggest a series of interconnected solutionally enlarged fractures in an orthogonal pattern at a depth of approximately 8 m immediately south of the ACME site.

    As part of technical assistance to the U.S. Environmental Protection Agency (USEPA) in the remediation of properties on the North Penn Area 6 Superfund Site in Lansdale, Pa., the U.S. Geological Survey (USGS) in 2006-07 collected data in four monitor wells at the Rogers Mechanical (former Tate Andale) property. During this period, USGS collected and analyzed borehole geophysical and video logs of three new monitor wells (Rogers 4, Rogers 5, and Rogers 6) ranging in depth from 80 to 180 feet, a borehole video log and additional heatpulse-flowmeter measurements (to quantify vertical borehole flow) in one existing 100-foot deep well (Rogers 3S), and water-level data during development of two wells (Rogers 5 and Rogers 6) to determine specific capacity. USGS also summarized results of passive-diffusion bag sampling for volatile organic compounds (VOCs) in the four wells. These data were intended to help understand the groundwater system and the distribution of VOC contaminants in groundwater at the property.
