Naval Base Kitsap - Bangor

Naval Base Kitsap (NBK) Bangor

 

NBK Bangor is on the Kitsap Peninsula in Kitsap County, Washington. The base is located on Hood Canal, approximately 6 miles north of Silverdale, Washington. Naval activities began at NBK Bangor in June 1944, when the U.S. Naval Magazine, Bangor, was established to provide a deep-water shipment facility for ordnance. From 1944 into the early 1970s, the Navy facility at Bangor was primarily used for shipment and storage of ordnance and demilitarization of unserviceable and dangerous ammunition. In February 1977, NBK Bangor was commissioned as the West Coast homeport for the Trident Submarine Launched Ballistic Missile System. The current mission of the base is to provide administrative and personnel support for submarine force operations and logistical support for other Navy activities.

 

 

Virtual Results Open House

Due to the COVID-19 pandemic, the Navy will be hosting a Virtual Results Open House in lieu of an in-person Results Open House. We invite you to attend the Virtual Results Open House that will be available to view beginning on 28 September 2020 at the following website: www.NavyBangorPFAS.com. The Virtual Results Open House will be available for viewing until 7 November 2020.

Emergency Response Action

The Navy is taking an emergency response action at NBK Bangor to mitigate potential public exposure to per- and polyfluoroalkyl substances (PFAS), specifically perfluorooctane sulfonate (PFOS) and perfluoroocatonoic acid (PFOA), in off-base drinking water wells near NBK Bangor, Silverdale, Washington.

Areas for PFAS Drinking Water Well Sampling

Since February 2020, the Navy has sampled 292 private drinking water wells within a designated area near NBK Bangor for certain per- and polyfluoroalkyl substances, commonly known as PFAS. PFAS are a family of thousands of different chemicals which have been widely used in industrial and consumer products since the 1950s. The Navy developed a policy to address past releases of PFAS at installations nationwide, as several PFAS are now of emerging public health concern to the Navy, U.S. Environmental Protection Agency (EPA), state regulatory agencies, and the general public. The EPA has issued a drinking water lifetime health advisory for two commonly used and studied PFAS, perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).

The most common Navy activity that could have resulted in the historical release of PFOS, PFOA, and other PFAS to the environment is the use of firefighting foam (specifically certain types of aqueous film-forming foam, or AFFF) for testing, training, firefighting, and other lifesaving emergency responses. Because of this historical use, there is potential for PFOS, PFOA, and other PFAS to be in the groundwater at the base, and also be present in nearby private drinking water wells that are located in the direction that the groundwater flows away from the base. The initial sampling area, as shown in Figure 1 and Figure 2, was selected because of the proximity to NBK Bangor and the general groundwater flow direction away from potential PFAS release areas. In addition, because there were results above the EPA’s lifetime health advisory in two private drinking water wells sampled in the initial sampling effort from February – April 2020, the Navy has expanded the designated sampling area. The expanded sampling area, as shown in Figure 2, was selected because of general groundwater flow direction away from the two private drinking water wells above the EPA lifetime health advisory. (Out of respect for owner privacy, location-specific results will only be released by the Navy to the owners.)

NBK Bangor Actions Based on Drinking Water Sampling Results

 

Since historical operations at NBK Bangor included the use of AFFF, the Navy began drinking water sampling for certain PFAS in drinking water wells in the initial sampling area in February 2020. PFOS/PFOA were found above the EPA lifetime health advisory level of 70 ppt in two drinking water samples, so the Navy is expanding the sampling area. The Navy provided bottled water for drinking and cooking for the two private drinking water wells with PFOS/PFOA above the EPA lifetime health advisory and will continue to do so until a long-term solution can be put in place. Table 1 summarizes the drinking water sampling results to date.

Identification of PFAS at NBK Bangor

The Navy’s priority with PFAS investigations is to identify and eliminate drinking water exposures above the EPA’s lifetime health advisory level.

Across the country, the Navy has been conducting base-wide evaluations to identify additional potential PFAS releases. These evaluations are being conducted under the federal cleanup program which meets the requirements of, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Following CERCLA, the Navy’s installation-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.  The recent preliminary assessment conducted at NBK Bangor identified 22 on-base areas where PFAS-related releases potentially occurred, and additional investigation is needed. These are listed below in Table 2.
