NAS WHIDBEY ISLAND, Wash. – The following update is provided as part of the Navy's ongoing community drinking water testing for the emerging, national environmental issue of PFAS (per- and polyfluoroalkyl substances).
- As of Feb. 4, 2017, the Navy has received 173 preliminary lab results from drinking water sampling at private residence and public supply wells in the areas surrounding both NAS Whidbey Island's Ault Field and Outlying Field (OLF) Coupeville properties.
- As of Feb. 4, 2017, the Navy has obtained 173 samples for analysis. Of the total 173 preliminary results received, eight preliminary results are above EPA lifetime health advisory level established for one of two specific PFAS, perfluorooctane sulfonate, PFOS and/or perfluorooctanoic acid, PFOA.
- The Navy has received 97 preliminary sample results from properties near OLF Coupeville and seven results are above the EPA lifetime health advisory.
- The Navy has received 76 preliminary results from properties near Ault Field and one sample result is above the life time health advisory.
As a reminder, the Navy will hold its next two open house public meetings on the results and future plans for its ongoing community drinking water sampling for PFOS and PFOA around NAS Whidbey Island facilities this week on Feb. 15 and 16, 2017.
The meeting on February 15 will be held in the Coupeville High School “commons” from 4–7 p.m. and in the Oak Harbor High School gym on February 16 from 5-8 p.m.
The Navy is providing drinking water to the owners of wells with drinking water concentrations that exceed the EPA’s lifetime health advisory as we work to validate the data and develop a long-term solution. The Navy will update property owners on their validated results.
Out of respect to residents' privacy, specific results will only be released by the Navy to the residents whom had their wells sampled. Speculating on the cause of any positive results is inappropriate and premature until thoroughly investigated.
The Navy continues to work directly with residents, community leaders and other federal, state and local agencies on this important national issue and will keep the community informed while respecting the privacy of individual residents.
People in the sampling area will be notified by letter and can arrange sampling by calling 360-396-1030. We encourage residents in the sampling area to have their wells sampled.

The Navy continues to investigate drinking water sources at Navy Installations worldwide where PFAS are suspected - typically at locations with historic use of Aqueous Film Forming Foam (AFFF), a highly effective, life-saving fire suppressant, which contains PFAS.
In Navy Region Northwest, this included investigating groundwater at NASWI and the OLF at Coupeville to determine if it is impacted from past releases of AFFF containing PFAS, which are classified by the EPA as unregulated or "emerging" contaminants and have no regulatory standards or routine water quality testing requirements.
The sampling will help the Navy determine if additional actions are needed to protect human health and the environment.
The Navy, in cooperation with other federal, state and local environmental and health agencies, will hold follow-up meetings on February 15 and 16 in Coupeville and Oak Harbor, respectively.
