Suspected contamination source: Firefighting foam used at Naval Air Station Whidbey Island (U.S. Navy, 2017)
Testing by the U.S. Navy near Naval Air Station Whidbey Island in early 2017 revealed PFAS levels above the EPA’s lifetime health advisory (HA) level of 70 parts per trillion (ppt) PFOA/PFOS. One well had levels as high as 2,516ppt. The Navy is providing drinking water to the owners of wells with drinking water concentrations that exceed the EPA’s lifetime health advisory
As of June 2017, the Navy is in the process of testing areas all over the country where it used PFAS-containing Aqueous Film Forming Foam (AFFF).
