Bioventing Test Work Plan and Interim Test Results Report for Underground Storage Tanks Located at Building 7705, Westover Air Force Base, Massachusetts
Abstract
This test work plan presents the scope of an in situ bioventing pilot test for treatment of fuel contaminated soils associated with the underground storage tanks (USTs) at Building 7705 (Pump House) at Westover AFB, Massachusetts. The 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 fuel when stimulated by oxygen rich soil gas, 3) to evaluate the potential for sustaining these rates of biodegradation until fuel contamination is remediated below regulatory standards. Pilot testing will consist of two phases, an initial air permeability and in situ respiration test which will take place in October of 1993, and an extended one-year pilot test which will be used to determine the potential for bioventing remediation using natural nutrient levels. Extended testing will also provide an estimate of cold weather biodegradation rates. The initial and extended pilot test will serve as treatability studies CERCLA feasibility study process. If bioventing proves to be feasible at this site, pilot test data may be used to design a full scale remediation system and to estimate the time required for site cleanup.
