Between 2013 and 2017, the Department of the Air Force (DAF) conducted world-wide sampling of drinking water at all Air Force installations where the Air Force provides the drinking water.  The Air Force has released results for both untreated and treated drinking water samples associated with DoD purveyor and non-DoD purveyor drinking water systems.  Water samples were analyzed using EPA Method 537 at DoD accredited laboratories.  The data include water results from surface and groundwater sources. However, these untreated water samples do not represent drinking water provided to the public.  Drinking water quality information will be provided in the annual water quality reports (i.e. Consumer Confidence Reports) located on the individual Air Force installation webpages and in EPA’s National Drinking Water Contaminant Occurrence Database.  The sampling data also include PFAS compounds detected by EPA Method 537 for which there were no EPA thresholds or HA limits prior to the release of EPAs Maximum Contaminant Levels (MCLs) in April 2024.

At DAF installations where PFOS/PFOA were sampled above 70 parts per trillion (prior to release of EPA MCLs), immediate actions have been taken, on and off installations, to ensure that no one is drinking impacted water where DAF is the known source. Additionally, DAF has worked with those respective communities to identify and implement solutions for alternative drinking water.

Visit the DoD's PFAS website to use the interactive map and learn more about the final testing results for off-base drinking water located in "covered areas." Covered areas are locations in the United States that are adjacent to and down gradient from a military installation, Formerly Used Defense site (FUDS), or National Guard facility.
