PFAS

July 2022

PFAS Information

Per- and Polyfluoroalkyl substances (PFAS) are not yet regulated under the Safe Drinking Water Act or other major U.S. environmental laws such as the Clean Air Act and the Clean Water Act. However, the Washington State Board of Health completed rulemaking to regulate PFAS in Group A drinking water systems. The rule sets State Action Levels (SALs) for five PFAS, and requires monitoring, recordkeeping and reporting, follow-up actions, and other associated requirements for PFAS.

Kitsap Public Utility District’s (KPUD) drinking water remains safe and protected from contaminants. We closely monitor drinking water regulations to ensure that we take actions necessary to protect our customers from the health risks of these chemicals.

Background

In late January 2020, KPUD was notified that the U.S. Navy would be testing groundwater wells around Naval Base Kitsap - Bangor for the presence of 18 different PFAS compounds.

PFAS is an umbrella term for a class of manmade chemicals used in a wide range of products including cookware, upholstery, and fast-food packaging. PFAS compounds are also used in firefighting foams that have been used on military bases.

There have been documented cases where PFAS from these firefighting foams have infiltrated into local aquifers. KPUD has one well in the Navy’s study area, which serves our Avellana water system and another just outside the study area that serves our Brianwood water system.

In February 2020, and again in September 2020, KPUD tested both these wells for the 18 PFAS compounds in the study. Both times, four compounds were detected at trace amounts that were all below the State of Washington’s action levels, and EPA’s health advisory levels at the time.

EPA Health Advisory Update

On June 15, 2022, the Environmental Protection Agency (EPA) announced updated lifetime health advisories for four PFAS compounds in drinking water. A lifetime health advisory identifies the level of a contaminant in drinking water that would protect all people from adverse health effects from a lifetime exposure to PFAS in drinking water. The EPA calculates health advisory levels including a margin of safety and to account for sensitive populations. For these reasons, health advisory levels may be set very low.

Although EPA health advisory are non-enforceable, non-regulatory levels, the EPA is expected to publish enforceable national drinking water standards for PFAS by the end of 2022. KPUD will be testing these wells and keeping users informed of any changes.

Where to Get More Information

PFAS FAQs

Is KPUD Water safe to drink?

Yes, water from KPUD meets all federal and state drinking water regulations and is safe to drink.

What are PFAS compounds?

According to the EPA, PFAS are manmade chemicals that have been manufactured in the U.S. since the 1940s, and are used in a variety of products, including non-stick, stain-resistant, water-resistant products available on the mass market. They are found in furniture, carpeting, non-stick cookware, outdoor clothing, food packaging and other common household products. Certain types of firefighting foam contain PFAS.

According to the Washington State Department of Health, PFAS exposure is widespread; it is estimated that PFAS may be found in the blood of 98% of the U.S. population. Although toxicity and safety data are still being developed, some of the PFAS compounds have been linked to health problems and environmental impacts.

PFAS have been detected in many drinking water sources around the country. PFAS contamination has been primarily discovered in areas near fire training facilities, military bases, and airports that historically used PFAS-based firefighting foam. In Washington State, PFAS have been detected in and around Naval Submarine Base Bangor, City of Issaquah, Joint Base Lewis-McChord, Naval Air Station Whidbey Island, and Fairchild Air Force Base/City of Airway Heights.
