摘要

The Multimedia Environmental Pollutant Assessment System (MEPAS) is an objective, physics-based computer code system that provides a means of quantifying relative risks from contaminants released into the environment. A baseline survey of DOE's major operating facilities is being conducted to identify and rank environmental problems and areas of environmental risk. The MEPAS model was used on 208 groups of problems associated with 16 sites located in 12 different states. Within 1 year, 208 groups of problems and some 500 transport scenarios were assembled, data were input, and model runs were made and analyzed. Findings from the surveys conducted at the 16 DOE sites were used to identify preliminary environmental problems. Using the MEPAS methodology as a basis for the ranking, these environmental problems are being ranked according to relative potential public health and environmental impact. The resulting Hazard Potential Index (HPI) is used to develop a preliminary ranking for each of the environmental problems. As a part of the Environmental Survey, DOE has issued a preliminary summary report that includes a preliminary ranking of potential problems at 16 sites associated with DOE's defense production mission. A final summary report addressing all 35 of the major DOE sites will re-evaluate the preliminary ranking and will incorporates the results of the Survey's sampling and analysis. 6 refs.
