Announcements and Key Topics

The U.S. Navy and Air National Guard continue to address the Per- and Polyfluoroalkyl Substances (PFAS) (formerly referred to as Perfluorinated chemicals (PFCs)) found at Naval Air Station Joint Reserve Base Willow Grove (NASJRB/WG) and the Willow Grove Air Reserve Station (WGARS). 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 NASJRB/WG. 

In mid-2014, PFAS know as Perfluorooctanoic Acid (PFOA) and Perfluoroooctane Sulfonate (PFOS) were found in drinking water wells near NASJRB Willow Grove. The EPA on the behalf of the Navy, samplied private drinking water wells located near NASJRB for PFOS and PFOA, from 2014 through mid 2017.

  • As of March 2018, more than 650 private drinking water wells have been sampled.
  • One hundred sixty nine (169) of the sampled wells exceed the lifetime health advisory combined levels of 0.07 micrograms per liter of water for PFOS 0.4 micrograms per liter of water for PFOS and PFOA. There are 108 properties receiving bottled water.
  • Eighty-one (81) of the 95 private drinking water wells have been converted to municipal water and the remaining 14 are being provided bottled water until they can be connected.
  • Seventy (70) private drinking water wells above 0.04 micrograms per liter of water, but below the health advisory level of 0.07, are continuing to be monitored.
