Expedited response action proposal (EE/CA EA) for 200 West Area carbon tetrachloride plume

Technical Report · Sun Sep 01 04:00:00 EDT 1991

OSTI ID:6917987

The report contains the proposal for an expedited response action (ERA) for the remediation of carbon tetrachloride contamination in the unsaturated soils beneath the 200 West Area of the Hanford Site. It provides the US Environmental Protection Agency (EPA) and the Washington State Department of Ecology (Ecology) with information regarding the need for the ERA and an evaluation of alternatives to reduce the mobility, toxicity, and/or volume of the carbon tetrachloride in the unsaturated soils. This report is intended to aid the EPA and Ecology in selecting a preferred alternative for implementing the ERA. This proposal does not address remediation of carbon tetrachloride in the ground water underlying the 200 West Area; nor is the radioactive waste mixed with the carbon tetrachloride in the disposal site the subject of this ERA. This report has also been prepared to address the requirements for an environmental assessment (EA). The purpose of this ERA is to prevent, or at least minimize, further migration of carbon tetrachloride contamination from the unsaturated soils to uncontaminated areas. This action is needed to ensure that the environment and public health are adequately protected and to reduce the threat of further groundwater contamination. Information on the origin, nature, and extent of carbon tetrachloride (and co-contaminants), and other site characteristics used as a basis for evaluating remedial alternatives is presented.
