Description:
The near field surface water model (SARAH2) 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 SARAH2 include groundwater leachate from a land disposal facility, storm runoff from a land disposal facility, and discharge through a waste water treatment facility or lagoon. The human exposure pathways considered include ingestion of treated drinking water and consumption of contaminated fish. Acceptable leachate or treated industrial waste discharge constituent concentrations are estimated by a procedure starting from chemical safety criteria in surface water, drinking water, or fish. Direct calculations predict the instream concentrations from leachate or discharge concentrations. SARAH2 is an interactive, menu-driven, modular FORTRAN computer program with three default data sets that can be modified rapidly.
