naval air development center (8 waste areas)


The Naval Air Development Center site, which covers 840 acres and is located in Warminster Township and Ivyland Borough, Bucks County, PA, was renamed Naval Air Warfare Center (NAWC) in 1993. Commissioned in 1944, NAWC's main function was the research, development and testing of Naval aircraft systems. Wastes were generated during aircraft maintenance and repair, pest control, firefighting training, machine and plating shop operations, spray painting, and various materials research and testing activities in laboratories. These wastes include paints, solvents, sludges from industrial wastewater treatment, and waste oils. Pursuant to BRAC, NAWC ceased operations in September 1996. Most of the property has been transferred to the private sector. NAWC is located in a populated suburban area and is surrounded by homes, commercial and industrial activities and a golf course. NAWC was placed on the CERCLA NPL due to the threat posed by eight disposal areas to groundwater quality. Prior to the discovery of PFC contamination during the 2012 Five Year Review, the primary groundwater contaminants of concern at NAWC have been found to be trichloroethylene (TCE), tetrachloroethylene (PCE) and carbon tetrachloride. The area surrounding NAWC is completely dependent on groundwater for both public and private water supplies. PFCs, mainly Perfluoroctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS), were first tested for as emerging contaminants in preparation for the 2012 Five Year Review. During this time, it was discovered that levels in groundwater on the former Navy property exceeded EPA provisional health advisory levels (HALs) for drinking water. Provisional HALs serve as informal technical guidance designed to assist federal, state and local officials in evaluating threats to local water supplies. Provisional HALs are not federally enforceable standards and are subject to change as new information becomes available. Outside of the CERCLA Five Year Review, in 2013, the EPA required many public water systems, including the Warminster Township Municipal Authority (WTMA), the local public water supplies in the area of NAWC, to sample for a group of 28 unregulated contaminants, including PFOS and PFOA. Based on the results, two public drinking water production wells impacted by PFOS and PFOA were taken off-line in June 2014. Site Responsibility This site is being addressed through Federal actions.
