Allocating cleanup costs at hazardous waste sites.

Contaminants in Aquatic Habitats at Hazardous Waste Sites: Mercury

The Office of Ocean Resources Conservation and Assessment (ORCA) provides decisionmakers comprehensive, scientific information on characteristics of the oceans, coastal areas, and estuaries of the United States of America. The information ranges from strategic, national assessments of coastal and estuarine environmental quality to real-time information for navigation or hazardous materials spil...

Risk Assessment of Polychlorinated Biphenyls at Hazardous Waste Sites

We recently reported a hazardous waste site in which polychlorinated biphenyls (PCBs) were at such high concentrations in soil that significant levels were found in indoor residential air. This paper uses the waste site to illustrate the complexities in exposure assessment and toxicity assessment of PCBs. Aroclors are commercial mixtures of different arrays of the 209 individual PCB congeners. ...

Basic Concepts of Contaminant Sorption at Hazardous Waste Sites

The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA's Regional Superfund Offices, organized to exchange up-to-date information related to ground-water remediation of Superfund sites. One of the major issues of concern to the Forum is the transport and fate of contaminants in soil and ground water as related to subsurface remediation. Processes which...

Hazardous waste landfill sites and congenital anomalies.

he EUROHAZCON collaborative group reported a further stage of their research on connections between congenital anomalies and hazardous waste landfill sites in the November 2002 issue of Occupational and Environmental Medicine. 1 An expert panel scoring method has been used to estimate the hazard potential of EUROHAZCON landfill sites and to investigate whether sites classified as posing a great...
