Bioventing Test Work Plan for Installation Restoration Program Site ST-27, Charleston AFB, South Carolina
Abstract
This site-specific work plan presents the scope of a bioventing pilot test for in situ treatment of fuel-contaminated soils at Installation Restoration Program (IRP) Site ST-27, Charleston Air Force Base, South Carolina. The proposed pilot test has three primary objectives: 1) to assess the potential for supplying oxygen throughout the contaminated soil depth in the study area, 2) to determine the rate at which indigenous microorganisms will degrade the fuel when stimulated by oxygen-rich soil gas, and 3) to evaluate the potential for sustaining these rates of biodegradation until fuel contamination is remediated below regulatory standards. As discussed in this work plan, the pilot test will be conducted in two separate phases in consideration of current site conditions and work scheduled by other contractors at this site. If bioventing proves to be a feasible technology for this site, pilot test data will be used to design a full-scale remediation system and to estimate the time required for remediating soils to regulatory standards. Several added benefits are expected during the pilot testing phase at Site ST-27. First, a significant amount of the fuel contamination in the test area should be biodegraded during the one year pilot test. Additionally, test conditions at this site will allow the Air Force to evaluate the effectiveness of bioventing in shallow water table conditions in conjunction with aquifer dewatering and product extraction.
