Gwinn KI Sawyer Air Force Base

Gwinn KI Sawyer Air Force Base is a site which reflects known PFAS levels. Based on environmental and health concerns, further review and possible action may be necessary to best protect public health. More details about this location will be made available as soon as possible.

  • The former K.I. Sawyer Air Force Base site first came to the DEQ’s attention in April 2014.
  • In addition to two fire training areas, other suspected sources of PFAS use were investigated, including three plane crash sites, fire suppression systems in a few locations, storm water infiltration basins, two streams, the Wastewater Treatment Plant (WWTP), two landfills, and undeveloped areas where WWTP sludges were land-applied.
  • From 2015 to 2016, hundreds of soil samples were taken, along with samples from the municipal water supply wells, groundwater, surface water, and at the WWTP.
  • In 2017 sampling of surface water, sediment, the WWTP, and residential wells has continued.
  • One of two residential wells has confirmed PFAS above screening levels.
  • Bottled water has been provided by the United States Air Force (USAF) upon receipt of the first sample, and negotiations are nearing completion for installation of a whole-house treatment system to be operated by the USAF for the resident.
