Abstract Previously funded EMSP research efforts have been directed towards the quantification of dense nonaqueous phase liquid (DNAPL) migration and entrapment behavior in physically and chemically heterogeneous systems. The research planned in this project seeks to build upon our previous research experience and expertise to explore the influence of waste and porous media composition on DNAPL migration and entrapment in the saturated zone. Specific objectives of this research are : (1) Relate measured interfacial properties for representative wastes and soils to parameters such as mineralogy, organic carbon content, pH, ionic strength, and DNAPL acid and base numbers. (2) Assess predictive procedures to estimate interfacial properties for DOE wastes and soils. (3) Deduce mechanisms of interfacial property alteration. (4) Quantify the influence of waste and porous medium composition on hydraulic properties and residual saturation. (5) Develop and assess constitutive hydraulic property and residual saturation models. (6) Explore the migration and entrapment behavior of model DNAPL wastes in spatially and temporally heterogeneous systems. (7) Develop and validate a multiphase flow model to simulate the migration and entrapment of model DNAPL wastes in heterogeneous systems. (8) Investigate the upscaling of findings from batch and soil column experiments to larger systems.
