USGS Co-Sponsors Special Session on Anaerobic/Aerobic Processes for VC and DCE Biodegradation, 2003 In Situ and On-Site Bioremediation Symposium

The U.S. Geological Survey (USGS) and the U.S. Navy co-sponsored a special session on "Anaerobic/aerobic processes for VC and DCE biodegradation" at the Seventh International Symposium on In Situ and On-Site Bioremediation, Orlando, Florida, June 2-3, 2003. The symposium is sponsored by Battelle http://www.battelle.org/. Vinyl chloride (VC) and dichloroethene (DCE) are common degradation products of industrial solvents, such as tetrachloroethene (PCE) and trichloroethene (TCE). Clean-up professionals are often faced with high concentrations of VC and DCE at TCE and PCE contamination sites where biodegradation processes have seemingly stalled at the VC and DCE degradation step. This session shed light on the biodegradation of these recalcitrant compounds. USGS scientists presented the following paper at the session.
