Abstract

Stable carbon isotope techniques have been suggested as diagnostic tools for assessing hydrocarbons biodegradation. The objective of this study was to determine if isotope fractionation can be used as a reliable indicator of MTBE biodegradation, whether natural or engineered. The MTBE plume at Naval Base Ventura County (Port Hueneme, California, USA) offers a unique setting to study the fate of MTBE using stable carbon isotopes. Dramatic decreases in MTBE concentrations as a result of biodegradation have been well documented at this site. MTBE stable isotope fractionations were tracked along with MTBE concentrations. Laboratory-scale microcosms show 6% enrichment on MTBE-δ 13C under aerobic conditions. However, limited fractionation was detected in field samples.
