Soil surfactant flushing is being considered for the remediation of contaminated soil at a Superfund Site at Hill Air Force Base (Hill AFB), Utah. Contamination at the site includes two pools of dense nonaqueous-phase liquid (DNAPL) near the location of previous disposal trenches. The DNAPL consists primarily of trichloroethene (TCE), with lesser amounts of other chlorinated solvents and oil and grease. The highly contaminated soils currently saturated with DNAPL are the most appropriate medium for the soil flushing technique. After extraction of the existing, mobile DNAPL, surfactants can be used to enhance the removal of residual contamination from the soils. A treatability study was conducted to evaluate the effectiveness of several types and concentrations of surfactants in enhancing the removal of TCE and other DNAPL contaminants from soil samples collected at the site, The laboratory studies included screening the selected surfactants for their effectiveness in solubilizing DNAPL. Batch tests were then conducted with the most effective surfactants to evaluate their ability to remove (through solubilization and mobilization) DNAPL constituents from the contaminated soils.
