New Remediation Technology Developed by USGS and Geosyntec Featured in EPA's Technology News & Trends

The cooperative effort between the U.S. Geological Survey (USGS) and Geosyntec Consultants to develop and pilot-test a permeable reactive mat to treat chlorinated volatile organic compounds (VOCs) discharging from groundwater seeps into the tidal wetlands was recently highlighted in an article titled “New Remediation Technology: Bioreactive Mat for Treatment of Chlorinated Volatile Organic Compounds in Wetlands at Aberdeen Proving Ground, Maryland” in the EPA’s fall issue of Technology News & Trends. The pilot test, in cooperation with the U.S. Army Garrison at Aberdeen Proving Ground (APG), Maryland, was primarily tested from October 2004 to October 2005 with a follow-on performance testing in September 2008. The WBC-2 culture and reactive mat were developed through a Cooperative Research and Development Agreement between USGS and Geosyntec.

Since the wetland pilot test, additional bench- and pilot-scale tests have shown that WBC-2 seeded bioreactors can degrade chlorinated VOCs in groundwater treatment plants at APG. The WBC-2 culture combined with lactate injection also has been tested in a fractured rock aquifer at White Sands Missile Range, New Mexico, to validate its use for complete anaerobic degradation of RDX and perchlorate. Current studies are investigating the potential for WBC-2 dechlorination of trichlorobenzene, dichlorobenzene and monochlorobenzene in wetlands at the Standard Chlorine of Delaware, Inc. Superfund site in New Castle County, Delaware.
