PART I: Bioventing Pilot Test Work Plan for PS-3 (Pumphouses 2 and 3) and PS-4 (Bulk POL Stoarage Area), Malmstrom AFB, Montana. PART II: Draft Interim Pilot Test Results Report for PS-3 (Pumphouses 2 and 3) and PS-4 (Bulk POL Storage Area), Malmstrom AFB, Montana

摘要

This work plan presents the scope of multiphase bioventing pilot tests for in situ treatment of fuel-contaminated soils at PS-3 (Pumphouses 2 and 3) and PS-4 Bulk Petroleum, Oils, and Lubricants (POL) Storage Area at Malmstrom Air Force Base (AFB) (the Base), Montana. The pilot tests will be performed by Engineering-Science, Inc. (ES). The three primary objectives of the proposed pilot tests are: 1. To assess the potential for supplying oxygen throughout the contaminated soil interval, 2. To determine the rate at which indigenous microorganisms will degrade fuel when supplied with oxygen-rich soil gas, and 3. To evaluate the potential for sustaining these rates of biodegradation until fuel contamination is remediated to concentrations below regulatory standards.
