Operations and Maintenance Manual, Record Drawings, and Summary of Initial Results for Expanded Bioventing System at Installation Restoration Program (IRP) Site 11, Beale Air Force Base, California

摘要

Five soil and seven soil vapor samples were collected by Parsons ES for laboratory analysis prior to system startup to establish baseline conditions. The soil samples were analyzed by Curtis and Tompkins. Ltd. of Berkeley, California for benzene, toluene, ethylbenzene, and xylenes (BTEX), total petroleum hydrocarbons (TPH), and halogenated volatile organic compounds (HVOCs). Soil samples with detectable concentrations of total TPH or BTEX were also analyzed for soluble concentrations of TPH and BTEX. One soil sample from an uncontaminated interval was analyzed for total organic carbon (TOC). The soil vapor samples were analyzed by Air Toxics, Ltd. of Folsom, California for volatile organic compounds (VOCs), including HVOCs, BTEX, and TPH. In addition, soil vapor samples were analyzed in the field using direct-reading instruments for oxygen, carbon dioxide, total volatile hydrocarbons (TVH), and ionizable compounds. Soil and soil vapor results are summarized in Tables 1, 2, and 3, and sampling locations are shown on Figure 1.
