UPDATE: Navy’s Drinking Water Sampling Results near NAS Whidbey Island

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 June 16, 2017, the Navy has received 211 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 Landing Field (OLF) Coupeville properties.

 

  • As of June 16, 2017, the Navy has obtained 218 samples for analysis. Of the total 211 results received, ten results are above EPA lifetime health advisory level established for one of two specific PFAS, perfluorooctane sulfonate, PFOS and/or perfluorooctanoic acid, PFOA.  During Phase 2 sampling, a duplicate sample was taken from a well within Phase 1 area to confirm the exceedance; both samples from this well were above the EPA lifetime health advisory. All Phase 1 and 2 drinking water laboratory results have been validated by a third party data validation firm.

 

  • The Navy has received 112 results from properties near OLF Coupeville and seven drinking well results are above the EPA lifetime health advisory.

 

  • The Navy has received 99 results from properties near Ault Field and three sample drinking well results (including one duplicate) are above the life time health advisory.

 

  • The Navy conducted Phase 3 of its drinking water sampling program from June 5-16, 2017. If you were not able to schedule sampling and you received a letter, please call 360-396-1030. The Navy may be able to extend the Phase 3 sampling timeframe to sample your well.

 

  • The Navy finished drilling 27 groundwater monitoring wells at OLF Coupeville on February 15, 2017. The Navy finished sampling these wells for PFOS and PFOA on March 4, 2017.

 

  • The Navy has received results from the new groundwater monitoring wells at the Outlying Landing Field in Coupeville. Three of the twenty-seven wells installed contained PFOS and/or PFOA above the EPA Lifetime Health Advisory. Based on the local hydrogeology the groundwater direction is generally to the south at OLF Coupeville.

 

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 develop a long-term solution.

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 result 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 have been notified by letter and can arrange sampling by calling 360-396-1030.  We encourage residents in the sampling area to have their wells sampled.

PROJECT BACKGROUND

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, held follow-up open house public meetings on February 15 and June 1 in Coupeville, and February 16 and May 31 in Oak Harbor.
