Superfund Record of Decision (EPA Region 10): Mountain Home Air Force Base,Operable Units 1, 3, 5 and 6, ID., September 27, 1995

摘要

This decision document presents the selected final remedial action for OperableUnits (OUs) Numbers 1, 3, 5, 6, and sites at the Lagoon Base in Mountain Home, Idaho. USAF, EPA, and IDHW have determined that no remedial action is necessary under CERCLA for soil or regional groundwater at 32 of the 33 sites within OU1, OU3, OU5, OU6, Lagoon Landfill, and Fire Training Area 8 to ensure protection of human health and the environment. The Limited Action alternative addresses the principal threat posed by Site ST-11 because the perched water would only present an unacceptable risk if site use changed and if the perched water could be used as a source of water for residential use. The No Remedial Action alternative for the regional groundwater includes at least annual monitoring of the regional groundwater.
