Description:
The nearfield surface model SARAH calculates maximum allowable hazardous waste concentrations based on predicted exposure to humans or aquatic life from contaminated surface water. The surface water contamination pathways analyzed in SARAH include groundwater leachate from a land disposal facility, storm runoff from a land disposal facility, and discharge through a waste water treatment facility. The human exposure pathways considered include ingestion of treated drinking water and consumption of contaminated fish. Acceptable leachate or industrial waste contaminant concentrations are predicted by a 'back calculation' procedure from chemical safety criteria in surface water, drinking water, or fish.
