Abstract: Contamination of soil and water by chlorinated solvents is widespread problem nationally and world-wide. The overall goal of this research addresses one of the most pressing needs regarding the cleanup of sites contaminated with chlorinated solvents. That is, to develop remedial treatments that can remove chlorinated solvents from low-permeable zones in contaminated aquifers. To accomplish this goal, we propose to construct a column and 2-D tank transport system that mimics the movement and behavior of chlorinated solvents in heterogeneous media containing transmissive and low-permeability zones. This transport system will allow us to methodically produce the phenomena known as "rebound," which is the release of chlorinated solvents from low permeability zones following the removal of solvents from transmissive zones. Once we can repeatedly produce "rebound" with our transport system, we will then validate and calibrate our proposed transport model describing this process and systematically evaluate, develop and fine-tune remedial treatments to remove chlorinated solvents from low permeable zones in contaminated aquifers.
