- The final remedy for the BAE Systems facility, consisting of groundwater treatment and monitoring and including institutional controls, was described in the March 2006 Final Decision and Response to Comments. The two groundwater treatment systems included in the final remedy, one in the West Warehouse Area and one in the Eastern Property Boundary Area, have successfully captured and treated contaminated groundwater at the Facility since the early 1990s.
- In December 2008 the Facility proposed a year-long shutdown of the West Warehouse Area groundwater treatment system to EPA and PADEP to determine if the system was still necessary. The proposed shutdown was approved and occurred from February 2009 to February 2010. Results from the shutdown period were generally favorable, with only a few wells showing slightly increased contaminant concentrations; however, upon further evaluation of these results and other remedial alternatives, the Facility decided to resume operation of the West Warehouse groundwater treatment system in July 2010.
- BAE Systems Land and Armaments L.P., formerly United Defense and formerly the BMY Division of the HARSCO Corporation, is located approximately 5 miles southwest of the City of York, PA. Operations at the Facility began in 1960. The Facility produces armored defense vehicles for the U.S. Department of Defense.
- The primary contaminants at the Facility are tetrachloroethene (PCE) and trichloroethene (TCE), which occur in groundwater beneath the Facility at low levels. Potential exposures to this contamination have been eliminated by implementing on-site groundwater capture and treatment systems, providing public water to nearby residents, and providing institutional controls that restrict groundwater use. The low levels of remaining groundwater contamination are not expected to be of concern regarding vapor intrusion to indoor air. Contaminated soils have been removed or remediated at the Facility.
- As an additional protective measure, institutional controls prohibiting the development of on-site wells for domestic uses and banning the use of groundwater beneath the Facility as a potable water supply were included in the final remedy. A map of these institutional controls can be viewed at the following website:
