Computer Models Used to Support Cleanup Decision Making at Hazardous and Radioactive Waste Sites
Abstract Efforts are underway to cleanup hazardous and radioactive waste sites located throughout the U.S. To help determine cleanup priorities, computer models are being used to characterize the source, transport, fate, and effects of hazardous chemicals and radioactive materials found at these sites. Although the U.S. Environmental Protection Agency (EPA), the U.S. Department of Energy (DOE), and the U.S. Nuclear Regulatory Commission (NRC) have provided preliminary guidance on the use of computer models for remediation purposes, there is only limited directed guidance on model selection and application at radiation contaminated sites. To identify what models are actually being used to support decision-making at hazardous and radioactive waste sites, a project jointly funded by EPA, DOE, and NRC was initiated. The purpose of this project was to: 1) identify models being used for hazardous and radioactive waste site assessment purposes; and 2) describe and classify these models. This report presents the results of this study. A mail survey was sent to around 550 persons engaged in the cleanup of hazardous and radioactive waste sites; 87 individuals responded. They represented organizations including Federal Agencies, National laboratories and contractor organizations. Although the questionnaire received widespread distribution, we acknowledge that some important organizations (e.g., U.S. Geological Survey) or personnel engaged in modeling at hazardous and radioactive waste sites were not contacted. The respondents identified 127 computer models that were being used to help support cleanup decision-making. The identified models included: Multi-Media (41 models); Ground Water (34 models); Air (20 models); Engineering (19 models); Surface Water (7 models), Geochemical (5 models); and, Utilities (1 model). These models were used at EPA (SUPERFUND), DOE (e.g., Defense, UMTRA, FUSRAP, and SFMP), and NRC sites. There were a few models that appeared to be used across a large number of sites (e.g., RESRAD). Most cleanup efforts, however, used site-specific models.
