Laboratory and field experiments were conducted in two petroleum-contaminated aquifers to examine the anaerobic biodegradation of benzene, toluene, ethylbenzene and xylene isomers (BTEX) under ambient conditions. Aquifer material was collected from locations at the source, mid-plume and end-plume at both sites, incubated under ambient conditions, and monitored for disappearance of the test compounds. In the mid-plume location at the second site, in-situ column experiments were also conducted for comparison with the laboratory microscosm and field-scale results. In the end-plume microcosms, biodegradation was variable with extensive biodegradation in some microcosms and little or no biodegradation in others.
