PFAS Investigation

The Navy started the drinking water investigation on Whidbey Island in November 2016. From November 2016 through July 2019, the Navy sampled 280 drinking water wells near Ault Field, OLF Coupeville, and the Area 6 Landfill for PFAS. Of the total 280 wells, samples collected from 15 wells (31 properties/15 wells) are above the EPA LHA level established for PFOS and/or PFOA. The Navy conducted four phases of drinking water sampling near Ault Field, two phases near OLF Coupeville, and two phases near Area 6 Landfill.

In October 2017, the Navy began biannual sampling of drinking water wells where PFAS were detected, and drinking water wells adjacent to properties with PFAS exceedances. These are precautionary measures to ensure residents living near our installations are not being exposed to PFAS in off-base drinking water. The Navy will continue biannual sampling until a long-term remedial solution is identified and implemented based on appropriate federal and/or state regulations.

People in the sampling areas were notified by letter and can arrange sampling -- if they haven't already done so -- by calling 360-396-6387. We encourage residents in the sampling areas to have their wells sampled.

The Navy is providing drinking water to well owners/users with impacted water above the EPA’s LHA. The Navy will update property owners on their validated results as they become available. Out of respect to residents' privacy, test results will only be released by the Navy to the affected resident.

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.
