Announcements and Key Topics

 

The U.S. Navy continues to address the Per- and Polyfluoroalkyl Substances (PFAS) (formerly referred to as Perfluorinated chemicals (PFCs)) found at the Naval Air Warfare Center (NAWC) site in Warminster Township and Ivyland Borough, Bucks County, PA, covering 840 acres.

PFAS are organic chemicals used in repellants for stains, water, oil, and grease and have been used in a variety of products such as the fabric of upholstered furniture, carpets, nonstick cookware, floor wax, and the lining of microwave popcorn bags. Firefighting foam also contains these chemicals and is the source of the PFAS contamination in the groundwater beneath NAWC. 

At the request of the U.S. Navy and the Air National Guard (ANG), the U.S. Environmental Protection Agency (EPA) continues to provided sampling and technical support for private drinking water wells in the Horsham, Warminster and Warrington, Pennsylvania areas for two PFAS compounds, Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA), found at the Willow Grove Naval Air Station Joint Reserve Base (NASJRB) in Horsham and the Naval Air Development Center, (NAWCDC) in Warminster from 2014 through 2017.
 
In May 2016, the EPA established a lifetime health advisory level (HAL) for PFOS and PFOA at 70 parts per trillion. When both PFOS and PFOA are found in drinking water, the combined concentrations of PFOS and PFOA should be compared with the 70 parts per trillion health advisory level.


The lifetime HAL for PFOS and PFOA is a guide for public drinking water systems; it is not a drinking water standard. As EPA continues to study the health effects of PFAS, including PFOS and PFOA, the lifetime HAL was set to protect the most sensitive populations (pregnant women and nursing infants) and therefore is protective of all populations for a life-time of exposure.
