| Abstract | Tertiary butyl alcohol (TBA) is one of the most widely distributed organic contaminants in ground water at gasoline spill sites. The U.S. EPA does not have a Maximum Contaminant Level (MCL) for TBA in drinking water. Nevertheless, many states have set standards for TBA in drinking water and clean up goals for TBA at gasoline spill sites. Because other contaminants, such as benzene and methyl tertiary butyl ether, are often biologically degraded in anaerobic ground water, the state agencies that implement the Under Ground Storage Tank program rely heavily on monitored natural attenuation to clean up these contaminants at gasoline spill sites. This report reviews the prospects for using monitored natural attenuation to manage the risk from TBA in ground water at gasoline spill sites. The report reviews the distribution of TBA in ground water at gasoline spill sites, the process that produces TBA from anaerobic biodegradation of MTBE, and the prospects for natural biodegradation of TBA in ground water. The report presents data from a microcosm study conducted by U.S. EPA on TBA degradation in sediment from six gasoline spill sites distributed around the United States. Finally the report reviews the limited knowledge on use of stable carbon and stable hydrogen isotopes to evaluate natural biodegradation of TBA at field scale. |
