In situ Bioremediation of Spills from Underground Storage Tanks: New Approaches for Site Characterization Project Design, and Evaluation of Performance

摘要

The report presents a systematic approach for the design of in situ bioremediation of hydrocarbon contamination in ground water from the determination of the total quantity of hydrocarbons in the aquifer to the utilization of that information in an actual field bioremediation demonstration. The report explains why the total quantity of hydrocarbons in an aquifer can only be determined by collecting cores. A procedure to acquire cores from a contaminated aquifer is described. The procedures described in the report were field-tested in designing a demonstration of the bioremediation of an aviation gasoline leak. The performance of the demonstration was consistent with the expected performance based on the preliminary site characterization using the described procedures.
