Design of the MEPAS Chronic Exposure Module
The MEPAS Chronic Exposure Module is designed to take time-varying, contaminant concentrations in environmental media (i.e., groundwater, surface water, air, and soil) and generate average contaminant concentrations in exposure media at the point of exposure or contact with receptors. The total time frame over which the environmental media concentrations occur is divided into discrete exposure intervals (which may or may not overlap) as determined by the user, and an average concentration is determined for each of these intervals. A full description of the design parameters, as well as scientific formulations for the various models, can be found in Strenge and Chamberlain, 1995 (PNL-10523) and accessed online by following this link:
