The report addresses the development of a surface water model and proposed use in land disposal restrictions decisions. The potential for exposure of humans and aquatic life to surface water contamination was considered. The surface water analysis encompasses contamination of streams through the interception with ground water contaminated by releases of hazardous constituents in leachate from land disposal units. The surface water screening procedure involves a back calculation using a fate and transport model with a Monte Carlo uncertainty analysis from concentrations that will not adversely affect human health, and the environment. The procedure outlined in the document was proposed to establish acceptable concentrations for specific chemical constituents in waste extracts that may be land disposed.
