This paper provides an overview of modeling investigations designed to explore the influence of textural heterogeneities on the migration, persistence, and surfactant enhanced solubilization of organic liquid contaminants in the subsurface. Multiphase flow and transport simulators are used to model the entrapment and surfactant enhanced recovery of perchloroethylene from saturated media. A laboratory-based linear driving force expression is used to represent solubilization. Simulation results illustrate the influence of local permeability variations and mass transfer limitations on remediation performance. Additional model simulations of a controlled laboratory sandbox experiment are used to highlight the strengths and weaknesses of current modeling approaches.
