Abstract

The U.S. Army Biomedical Research and Development Laboratory has been involved in site cleanup assessment problems since 1974, predating the passage of Superfund legislation. The approaches developed in the last 15 years have been adapted into a software package, the Pollutant Hazard Assessment System (PHAS20). FHAS20 conforms with regulatory guidance concerning baseline health assessments and is intended to assist decision makers through the various steps of a baseline assessment or similar risk assessment exercise. PHAS20 includes selected chemical property estimation methods and closed-form transport/transfer models to provide data inputs when reported or experimental data sources are not available. Rersults appear in a format that enhances integration of environmental biota effect considerations into the public health assessment process.
