LHAAP-03, also known as Site 03, or the Former Waste Collection Pad, is approximately 50 feet to the west of former Building 722-P, paint shop. LHAAP-03 was a waste collection Site outside of the paint shop at Building 722-P, which was at the Maintenance Shop Area within the boundary of LHAAP-35A(58). Building 722-P was used for paint spraying and polyurethane spray coating of various items. Metal-based primers, other waste paint, waste solvents and contaminated rags were collected in a 55-gallon drum on a gravel pad in an open-sided shed. Full drums were taken to Building 31-W for disposal. Building 722-P has been demolished.
Various investigations have been conducted at LHAAP-03 to evaluate the nature and extent of soil and groundwater impact at the Site. These investigations have included multiple rounds of soil sampling and analyses, installation of a groundwater monitoring well, and groundwater sampling and analyses. LHAAP-03 lies entirely within LHAAP-35A(58) and groundwater is being addressed as part of the remedial action for the larger Site, LHAAP-35A(58).
