In May 2017, the City's domestic water supply was found to be impacted by chemicals known by the acronyms PFOS and PFOA, ingredients found in fire-extinguishing foam and other materials. The Chemicals are believed to have seeped into the groundwater from a fire training site on the eastern edge of Fairchild Air Force Base.
City water users were advised in early May not to use tap water for drinking or cooking. Safe water supplies (bottled water and alternative sources from the City of Spokane water system) were provided to City residents while environmental investigations were conducted. The advisory was lifted on June 8, 2017.
Other community wells provide water to some residents who are not on the City's water system. Fairchild Air Force Base officials are continuing to sample and test these wells, and alternate sources of water continue to be provided to some individual well users.
