PART I: Bioventing Pilot Test Work Plan for South Gas Station (SGS) Site Fuel Storage Area G (Site 1) Travis Air Force Base, California. PART II: Draft Interim Pilot Test Results for South Gas Station (SGS) Site Fuel Storage Area G (Site 1) Travis Air Force Base, California
Abstract
This Test Work Plan presents the scope of in situ bioventing pilot tests for treatment of fuel contaminated soils at the South Gas Station (SGS) Site and Fuel Storage Area 0 (Site 1) at Travis AFB, California. The site locations are shown in Figures 1.1 and 1.2. The pilot tests have three primary objectives: 1) to assess the potential for supplying oxygen throughout the fuel hydrocarbon-contaminated soil zone; 2) to determine the rate at which indigenous microorganisms will degrade the fuel in the soil when stimulated by oxygen rich soil gas; and 3) to evaluate the potential for sustaining these rates of fuel biodegradation until the fuel contamination is remediated below regulatory standards. The bioventing pilot tests at Travis AFB, California will be divided into two test events. An initial pilot test will determine the technical feasibility and important design parameters such as air permeability, fuel biodegradation rates, radius of influence, and potential air emissions (requirements for emissions treatment). An extended (one-year) pilot test will determine the long-term application of this remedial technology to degrade hydrocarbons at each site. If bioventing proves to be applicable, pilot test data could be used to design and implement a bioventing remediation system. A significant amount of the fuel contamination should be biodegraded during the extended (one-year) pilot tests since the bioventing will take place within the most contaminated soils at each site.
