Abstract: Dissolution is one of the key physiochemical processes controlling subsurface remediation of nonaqueous phase liquid (NAPL) pools. One process that can accelerate NAPL pool dissolution is in situ biodegradation. The ...

Abstract: Monitored natural attenuation has become accepted as an appropriate “technology” for treating petroleum hydrocarbon-contaminated groundwater. Commonly, the monoaromatic compounds benzene, toluene, ethylbenzene, and xylenes ...

Abstract: Bench-scale reactor experiments were performed to study the dissolution of a binary naphthalene-in-nonane mixture nonaqueous phase liquid (NAPL) pool over a wide range of average pore water velocities,

Abstract: Transfer of oxygen across the capillary fringe and water table is a critical oxygen source for aerobic biodegradation of hydrocarbon light nonaqueous phase liquids (LNAPLs) at or near the water table. However, significant ...

Abstract: Surfactant amendment has been proposed as a means to stabilize or mobilize groundwater contamination by modifying the soil’s natural sorption characteristics in situ. The importance of the native soil’s characteristics ...

Abstract: Biological processes may provide great and previously unexplored opportunities for cost-effective, in situ improvement of the engineering properties of soil. A laboratory study was conducted to evaluate the changes in ...
