Abstract:

Chlorinated volatile organic compounds cVOCs, such as trichloroethylene TCE and perchloroethylene PCE, represent one of the largest remediation challenges and costs at U.S. Department of Defense DoD sites. Anaerobic bioremediation via organic carbon source addition with or without bioaugmentation with dechlorinating bacteria is a commonly used approach to remediate cVOCs in situ. One significant issue with this approach is that reductive dechlorination processes are typically inhibited at pH values 5.5. Aquifers with lower pH values are common, especially in the eastern United States. Raising the groundwater pH is often not feasible because of the large amount of buffer needed, the large size of many plumes, and the need for long-term treatment and repeated reinjections.
