Many Superfund sites include rivers, reservoirs, and other surface bodies of water (and the adjacent floodplains) that are highly contaminated with PCBs, metals, and other toxic chemicals. Examples of contaminated waters are the Hudson, Fox, Housatonic and Clark Fork Rivers, Lake...

The document will be an updated draft metholodogy for cancer risk assessment of asbestos. The draft methodology will address potential differences in cancer potency of different fiber types and different fiber dimensions of asbestos.

This document presents results from site monitoring activities during calendar year 2008 at the EPA/ORD Red Cove Study Area relative to site characterization activities under Operable Units 01 (Shepley's Hill Landfill) and 11 (Plow Shop Pond) at the Fort Devens Superfund site. T...

The purpose of the report is to study the social and economic issues involved in cleaning up Superfund sites. EPA usually avoids making land use an explicit consideration when the Agency chooses a cleanup strategy. Yet post-remediation land use assumptions are part of the risk as...

The study explored modeling approaches for assessing potential risks to children from air lead emisions from the RSR Superfund site in Dallas, TX. The EPA Integrated Exposure Uptake Biokinetic model and the International Radiologic Protection lead model were used to simulate blo...

NHEERL's research in this area focuses on ecological effects of bioaccumulative chemicals, such as PCBs. The research is designed with recognition that sites of different size and complexity require bioaccumulation models with correspondingly complex and/or extensive data requir...

The purpose of this presentation is to describe the different technologies that the Office of Research and Development (ORD) of the U.S. Environmental Protection Agency has tested on bench, field and pilot studies on mine-influenced water. Each of these technologies has been dem...

The ERD has a long history in providing model research and development and technical support to Regions, States and the Office of Water for watersheds/water quality ecosystem research. The ERD efforts are described in major subtasks comprising the Program. Briefly, these are:<b...

Fort Devens was established in 1917 as Camp Devens, a temporary training camp for soldiers from the New England area for WWI. Throughout its history, Fort Devens served as a training and induction center for military personnel, and as a unit mobilization and demobilization site....

This document presents results from the Fiscal Years 2006-2008 field investigation at the Fort Devens Superfund Site, Operable Unit 1 (Shepley's Hill Landfill) to fulfill the research objectives outlined in the proposal entitled, 'Fate and Transport of Arsenic in an Urban, Milita...

Over the past fewyears, it has become increasinsly evident that land disposal of hazardous wastes is at least only a temporary solution for much of the wastes present at Superfund sites. The need for more Iong-term, permanent "treatment solutions as alternatives to land disposal ...

Passive samplers are monitoring tools that can provide faster, cheaper, and scientifically-sound information about the water column and interstitial water concentrations of contaminants of concern (COC) at Superfund sites. Often, the use of passive samplers is more effective tha...

At contaminated sediment sites, the Superfund program usually must decide whether to leave the site alone, cap it, or dredge it. This decision is based in part upon the relative risk to the environment and human health posed by each alternative. Whatever decision is made at a s...

At contaminated sediment sites, the Superfund program must decide whether to leave the site alone or select a remedial option. These decisions are based in part on the relative risks to the environment and health posed by each alternative. Whatever decision is made at a site, the...

The EPA Office of Solid Waste and Emergency Response's (OSWER) Office of Superfund Remediation and Technology Innovation (OSRTI) needs innovative methods and techniques to solve new and difficult sampling and analytical problems found at the numerous Superfund sites throughout th...

Oral presentation dicumenting several completed Superfund remediations using solidification/stabilization, both in situ and ex-situ, to treat soils containing metals and organics.<br>65 slide presentation.

The U.S. Environmental Protection Agency's Office of Research and Development (ORD), joining with the Office of Solid Waste and Emergency Response (OSWER), has initiated the Superfund Innovative Technology Evaluation (SITE) program. The SITE program will help EPA find, test, and ...

The 1984 Hazardous and Solid Waste Amendments (HSWA) of the Resources Conservation and Recovery Act (RCRA) require that EPA either ban the disposal of hazardous wastes to the land or ascertain that such wastes are acceptable for land disposal. he soil and debris associated with t...

In 1987, the U.S. Environmental Protection Agency’s (EPA) Office of Research and Development (ORD), Office of Land and Emergency Management, and EPA Regional waste management offices established the Technical Support Project. The creation of the Technical Support Project enabled...

The Superfund Innovative Technology Evaluation (SITE) Emerging Technology Program (ETP) has encouraged and financially supported further development of bench- and pilot-scale testing and evaluation of innovative technologies suitable for use at hazardous waste sites for five year...

Incineration is often the preferred technology for disposing of hazardous waste, and remediating Superfund sites. The effective implementation of this technology is frequently impeded by strong public opposition `to hazardous waste' incineration HWI). One of the reasons cited for...
