ABSTRACT
Enhanced anaerobic biodegradation of groundwater contaminated by fuel hydrocarbons has been evaluated at the Naval Weapons Station, Seal Beach, California. This field experiment included the establishment of three different remediation zones in situ: one zone was augmented with sulfate, one was augmented with sulfate and nitrate, and the third was unaugmented. In the zones that were augmented with sulfate and/or nitrate, the added electron acceptors were consumed quickly, indicating that enhancement via electron acceptor injection accelerates the bio-degradation process. Certain fuel hydrocarbons were degraded preferentially over others, but the order of preference depended on the geochemical conditions.
