Landfill B is a 14-acre site at Westover AFB that was used for domestic and general refuse disposal from 1960 until 1974. Refuse that may have been placed in Landfill B include drums from industrial operations. These drums may have contained paint residues, thinners, strippers, and other cleaning compounds such as methyl ethyl ketone MEK, various chlorinated solvents, and dichlorobenzene DCB. Several environmental investigations have been performed at Landfill B under the Air Force Installation Restoration Program IRP by the Air ForceDepartment of Defense, which have lead agency status pursuant to Section 10 of the United States Code Part 2701 10 USC 2701 et seq. and 42 USC 9620. The Air Force IRP conforms with the US Environmental Protection Agencys USEPAs standard remedial investigation RIfeasibility study FS process. In 1988, a Phase II report detailing the outcome of a Phase I initial site assessment and Phase II evaluation was completed ES, 1988. Based on this information, a final RI report, which included a quantitative baseline risk assessment BRA, was prepared under the IRP in 1991 Chem-Nuclear GeoTech, Inc. Geotech, 1991. Subsequent to these reports, additional groundwater quality characterization activities were completed Environmental Compliance Services, Inc. ECS, 1993.
