Abstract:
Use of chlorinated solvents has led to extensive soil and groundwater contamination. Current aerobic treatment methods, such as pump-and-treat with carbon sorption or air stripping, are limited and often cost-prohibitive. Researchers have isolated microbial cultures capable of reductively dechlorinating tetrachloroethene (PCE) to ethene (ETH). Field studies have shown reductive dechlorination of chlorinated solvents to be stimulated by the addition of electron donors. Based on these results, this project utilizes indigenous bacteria and added electron donors for degradation of PCE in the field. The approach is designed to achieve a rigorous mass balance on electron donors, electron acceptors, and microbial carbon/energy sources. The effort is aimed at validating reductive dechlorination in a realistic field situation.
