Remedial Action Priority System (RAPS): Comparison between Simulated and Observed Environmental Contaminant Levels.

摘要

The Remedial Action Priority System (RAPS) is an objective, physics-based, fully integrated multimedia environmental assessment methodology. RAPS assesses environmental issues associated with hazardous and radioactive mixed-waste sites based on relative human health risk and limited site information. the purpose of this paper is to report on the results associated with applying components of the RAPS methodology to a variety of sites with different contaminant release mechanisms. These applications illustrate the type of data typically required to implement the methodology and several of the types of contaminant releases (e.g., direct discharge, French drain, cribs, tile field, and stacks) that can be considered by the methodology. They thus demonstrate the applicability of the methodology at a wide variety of sites. The various components of the RAPS methodology have been implemented at actual sites where contaminant levels have been monitored in the environment. The monitored contaminant levels are compared to simulated contaminant levels associated with the application to the RAPS methodology at these sites. The purpose of the comparison is to demonstrate the applicability of implementing RAPS to a wide variety of hazardous waste sites and releases of contaminants into the environment. 21 refs., 13 figs.
