Subject: Actions taken by the 111th Attack Wing (ATKW) to address PFAS (Per- and Polyfluoroalkyl substances) issues.
Background: PFAS are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. These coatings can be used in such varied products as clothing, furniture, adhesives, food packaging, heat-resistant non-stick cooking surfaces, and the insulation of electrical wire. Firefighting foams used at military and commercial airports contain PFAS. Many chemicals in this group have been a concern because they do not break down in the environment, can move through soils and enter drinking water sources, and they build up in fish and wildlife.
The 111th ATKW has been actively working to address PFAS issues at Biddle Air National Guard Base since they were first discovered and confirmed in 2014. The 111th has partnered with local communities, Navy, Air National Guard (ANG), U.S. Air Force (USAF), PA Department of Environmental Protection (PADEP) and the US Environmental Protection Agency (EPA) to address drinking water quality, and storm water run-off from the base.
• Presently, Biddle ANG Base/111th ATKW is in compliance with the Environmental Protection Agency's lifetime health advisory (HA) level for PFOS and PFOA of 70 parts per trillion (ppt). Where the Department of Defense (DoD) is the known source of PFAS, no one (on or off base) is drinking water above these levels.
• The DoD, USAF, ANG and Biddle ANG Base/111th ATKW are moving forward in a systematic, enterprise-wide approach in their response to PFAS. This approach requires extensive coordination with all parties to ensure consistency across all DoD installations.
