Bioventing Test Work Plan for Building 818 UST Fuel Release Site Langley AFB, Virginia
Abstract
This site-specific work plan presents the scope of a bioventing pilot test for in situ treatment of fuel-contaminated soils at Building 818, Langley Air Force Base, Hampton, Virginia. The proposed test site is a former leaking #2 fuel oil underground storage tank (UST) located adjacent to Building 818 in a base family housing area. Existing site assessment data was evaluated and it was determined that the Building 818 site is suitable for a bioventing pilot study. Although the base is currently evaluating additional sites to include in the bioventing pilot test program, a second pilot test site has not been identified to date. For this reason, this work plan focuses exclusively on the Building 818 test site. If a second pilot test site is selected, the test protocols and field procedures described in this work plan will apply to both bioventing test sites. The proposed bioventing pilot test has three primary objectives: 1) to assess the potential for supplying oxygen throughout the contaminated soil depth, 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. If bioventing proves to be a feasible technology for the 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. An added benefit expected at the pilot testing site is that a significant amount of fuel contamination should be biodegraded during the test, since the testing will take place within the most contaminated soils that have been detected on the site.
