PFOS/PFOA Frequently Asked Questions
Collapse All Expand All
A. Two synthetic compounds classified as PFCs, PFOS and PFOA, are components of Aqueous Film Forming Foam (AFFF), a type of fire-fighting foam. AFFF is the most efficient extinguishing method for petroleum-based fires and is widely used across the firefighting industry, to include all commercial airports, to protect people and property.

A. Since the 1970s, the Air Force used this foam at crash sites, in fire training areas and some maintenance hangers at active, Reserve, Air National Guard and former installations. The Air Force is systematically testing for potential PFOS/PFOA releases in soil, surface water and groundwater Air Forcewide where AFFF may have been used.

A. The Air Force identified approximately 200 installations (active, Reserve, Air National Guard and closed) where firefighting foam may have been released and is conducting site inspections to confirm if releases occurred. As of November 2016, the Air Force completed preliminary assessments for 96 percent of the 200 installations. The Air Force is prioritizing sampling based on factors, such as; potential pathways to drinking water, depth to groundwater and potential for contaminate to migrate off base.

A. The Air Force is focused on three lines of effort to address PFOS/PFOA contamination of drinking

water supplies:


  • Identify: Researchers identify fire training areas, crash sites and areas at installations where AFFF was used. At locations where a release may have occurred, investigators conduct groundwater, surface water, soil and sediment sampling for verification. If pathways exist to drinking water sources, the Air Force will test public water systems and private wells.
  • Respond: Where PFOS/PFOA levels exceed health advisory levels in drinking water supplies, the Air Force will immediately provide alternate drinking water sources. The Air Force will then identify and initiate a long-term solution to provide safe drinking water, which may include carbon filtration systems, plume-migration control, land use control, etc.
  • Prevent: The Air Force is replacing legacy AFFF with more environmentally responsible AFFF approved for military use and with concentrations below the EPA’s health advisory levels. The Air Force is also evaluating the best approaches to reduce the risk of inadvertent discharges and ensure containment in hangar fire prevention systems.
A. Requests for environmental sampling for PFOS/PFOA by regulatory agency officials are addressed on a case-by-case basis. In cases where a specific local, state or federal regulation or agreement is driving the request, the installation must have reason to believe a release of PFOS/PFOA is probable based on past installation activities, and be able to determine if an exposure pathway exists for the contamination to potentially threaten public health or migrate outside installation boundaries. In the absence of a legal requirement, the Air Force will continue to follow Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) guidance in its systematic approach for addressing PFOS and PFOA Air Force-wide at targeted Air Force environmental sites.

A. The Air Force is testing all drinking water supplies where it is the purveyor. If test results exceed the EPA’s lifetime health advisory level, the Air Force will immediately provide a safe drinking water source and follow the EPA-recommended actions, which include retesting, communicating with local regulators and drinking water officials, proper consumer notification and evaluation of options to reduce PFOS/PFOA concentrations below the lifetime HA.

A. The Air Force does not have authority to pay for blood tests at this time.

A. The Air Force’s priority is protecting human health and drinking water sources. If your well yields PFOS/PFOA above the health advisory, the Air Force will immediately provide clean drinking water. This may include supplying your household with bottled drinking water, connecting your home to a public drinking water supply, or installing a treatment/filtration system on your private well.
