This study provides a review of the literature on multiphase flow and transport (MPFT) models of organic chemicals in the subsurface. Unlike water borne solutes, organic compounds can move in nonaqueous phase liquid mode or in gaseous phase form through the porous media. The literature reviewed indicated that MPFT models can be divided into three groups: (1) sharp interface models; (2) immiscible flow models which incorporate capillarity; and (3) models dealing with interphase mass transport. This literature review suggests that MPFT models for migration of organic compounds have several problems. A major modeling problem is the inaccurate representation of geochemical and biotic processes which control the release and transformation of chemicals in the waste and subsequently in the geological medium. In addition, data to use models are currently unavailable. Also the models are very costly to use. This report contains recommendations for future research on model development, validation, and application. 182 refs., 7 figs., 4 tabs.
