Predicting the fate and transport of hazardous constituents from hydrocarbon contaminated soils is an integral part of assessing constituent migration potential and exposure risks. This paper highlights a systematic methodology that was adopted for evaluating health risks associated with releases of hazardous air contaminants from a land treatment unit in the southwest. Included are procedures for estimating releases of constituents using mathematical models, site environmental and operating data, and literature references. Release estimates provided input to atmospheric dispersion models which translated releases to predicted ambient constituent concentrations. These concentrations were then compared with health-based standards to assess environmental exposure risk. Release estimates were prepared for both long-term and short-term emissions to address chronic and acute effects thus ensuring a comprehensive assessment of health and environmental risk. Since there are normally no point sources associated with contaminated soils, only fugitive particulates were considered.
