PART I: Bioventing Pilot Test Work Plan for Building 30, Above ground Soil Pile, and POL Storage Area Sites, Offutt AFB, Nebraska. PART II: Draft Interim Pilot Test Results Report for Building 30 and POL Storage Area, Offutt AFB, Nebraska

摘要

This work plan presents the scope of enhanced biological degradation, or 'bioventing', pilot tests for treatment of fuel-contaminated soils at three sites located at Offutt Air Force Base, Omaha, Nebraska. At two sites, Building 30, and the petroleum, oils, and lubricants (POL) storage area, in situ pilot tests will be performed. At the third site, an aboveground bioventing pilot test will be performed in a test cell constructed using soils previously excavated from the POL area. The pilot tests have three primary objectives: (1) to assess the potential for supplying oxygen throughout the contaminated soil interval, (2) to determine the rates at which indigenous microorganisms will degrade fuel when stimulated by oxygen-rich soil gas, and (3) to evaluate the potential for sustaining these rates of biodegradation until fuel contamination in the soil is remediated to concentrations below regulatory standards.
