摘要

This site-specific work plan presents the scope of proposed bioventing pilot tests for in situ treatment of fuel-contaminated soils at two sites at Shaw Air Force Base, Sumter, South Carolina. The first bioventing test site is located at Former Fire Training Area Number 1, designated as Installation Restoration Program (IRP) Site FT-Ol. This lRP site comprises base Operable Unit Number 4 (OU-4). The second bioventing test site is located at OU-l within the confines of the base Petroleum, Oil, and Lubricant (POL) Bulk Fuel Storage Facility (POL Depot). The pilot test area will be located in the vicinity of a former 1,000-gallon reclaimable fuels underground storage tank (UST). The proposed test area is immediately adjacent to IRP Site SS-15, the lRP designation originally assigned to a leaking 25,000-gallon UST containing JP-4 jet fuel (UST Number 5). Based on information provided by Shaw AFB, all leaking USTs and ancillary piping within the POL Depot are now considered a part of IRP Site SS-15, since releases from an unknown number of the UST systems have merged to form a somewhat contiguous plume of soil and groundwater contamination within the facility. For these reasons, the bioventing pilot test location at the POL Depot is referred to as lRP Site SS-15 in this work plan. The test objectives, test protocols and field activities presented in this work plan will be similar for both pilot test sites. Minor modifications will be made to the individual bioventing systems as required to accommodate site-specific conditions.
