Airway Heights seeking $22M for new water source after firefighting foam contamination Airway Heights recently completed an analysis of alternatives for a long-term water solution, which pointed to the development of a new well. Author: Megan Carroll Updated: 8:47 AM PDT April 1, 2021 AIRWAY HEIGHTS, Wash. — The City of Airway Heights is seeking $22 million from state and federal officials for a new well after the city's domestic water supply was impacted in May 2017 by chemicals found in fire extinguishing foam and other materials. Tests done in May 2017 showed that the city's water supply had been impacted by PFOS and PFOA. The chemicals seeped into groundwater from a fire-training site on the eastern edge of Fairchild Air Force Base, according to the city. A 2018 Washington state law later restricted the use of PFAS in firefighting foam and personal protective equipment.
