OLF Coupeville On-Base PFAS Investigation



Across the country, the Navy has been conducting base-wide evaluations to identify additional potential PFAS releases. These evaluations are being conducted under the Navy’s Environmental Restoration Program which meets the requirements of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Following CERCLA, the Navy’s base-wide assessments are called preliminary assessments/site inspections, and their purpose is to verify, validate, and update the inventory of PFAS release sites aboard the installation for further investigation and cleanup. 

At NAS Whidbey Island, the Navy has completed preliminary assessment for Outlying Landing Field (OLF) Coupeville. The PA identified 3 sites with potential PFAS releases. A site inspection (SI) will be conducted at each site to determine the presence or absence of PFAS in the soil and/or groundwater. The SI for OLF Coupeville is being conducted in phases. The Final PA, Sampling and Analysis Plans (SAPs) and Technical Memorandums for the SI are under “Documents” below.  For sites where PFAS is confirmed, a remedial investigation will be conducted. The purpose of a remedial investigation is to delineate the extent of PFAS and conduct human health and ecological risk assessments to determine if a remedial action is required. More information will be added to this website as it is available.
