PFAS Mitigation

We have been proactively testing and reporting PFAS levels since 2020. In 2023, we began a quarterly program of testing and reporting for PFAS in drinking water. During this time, we’ve been evaluating drinking water filtration technologies to remove PFAS from the water supply. These mitigation strategies will help us continue to provide clean, reliable drinking water to our community.

We are currently planning and designing PFAS treatment system upgrades for Water Stations 14, 4, 9, 3 and 1. As long-term mitigation upgrades are implemented, both PFOS and PFAS concentrations in our water system will decrease. These filter treatment systems will allow our water utility to continue to meet the community’s expectation of safe, reliable water service.

Water Station 14

Water Station 14 PFAS sampling has consistently been the highest of all water stations and has been at or exceeded state and federal regulations. Treatment for this water station is a priority. Designs are complete for a new full-scale PFAS filter treatment system for this site.

Location: Northeast Andresen Road and Northeast 78th Street

Construction: Anticipated to start in 2026; work will continue at the site for two years.

Funding: This project was awarded a $12.5 million forgivable loan from the Washington State Department of Health through the Drinking Water State Revolving Fund Loan Program.

Water Station 4

Water Station 4 sampling has consistently been at or exceeded the state and federal regulations. Upgrades are needed to remove regulated PFAS, and this water station has been identified as a priority for treatment. We are designing a new full-scale PFAS filter treatment system for this site.

Location: Southwest corner of South Blandford Drive and East Fifth Street

Construction: Anticipated to start in 2026; work will continue at the site for two years.

Funding: This project was awarded $25 million through local, state and federal funding. The Washington State Department of Commerce’s Public Works Board awarded $10 million in a low-interest loan. The Washington State Department of Health through the EPA’s Drinking Water State Revolving Fund awarded $15 million, $3 million is a low-interest loan with the remaining $12 million being a forgivable loan.

Water Station 9

Status: Water Station 9 sampling has consistently been at or exceeded the state and federal regulations. Upgrades are needed to remove regulated PFAS, and this water station has been identified as a priority for treatment. We are designing a new full-scale PFAS filter treatment system for this site.

Location: Northeast 39th Street and Northeast 145th Avenue

Construction: Anticipated to start in 2027; work will continue at the site for two years.

Funding:  The City has applied for funding for this project through the Water Infrastructure Finance and Innovation Act (WIFIA) and $12 million forgivable loan from the Washington State Department of Health through the Drinking Water State Revolving Fund Loan Program.

Project elements:

Water Station 3

Status: Water Station 3 sampling has consistently been at or exceeded the state and federal regulations. Upgrades are needed to remove regulated PFAS, and this water station has been identified as a priority for treatment. We will be coordinating with an engineering consultant to start design work fall 2025.

Location: Northwest Washington Street at Northwest 43rd Street

Construction: Anticipated to start in 2027; work will continue at the site for three years.

Funding:  The City has applied for funding for this project through the Water Infrastructure Finance and Innovation Act (WIFIA) and will continue to pursue other funding sources to offset local costs.

Project elements:

Water Station 1

Status: Upgrades are needed to remove regulated PFAS, and this water station has been identified as a priority for treatment. We will be coordinating with an engineering consultant to start design work in early 2026.  

Location: East Fourth Plain Boulevard and East Reserve Street

Construction: Anticipated to start in late 2027; work will continue at the site for two years.

Funding: The City has applied for funding for this project through the Water Infrastructure Finance and Innovation Act (WIFIA) and will continue to pursue other funding sources to offset local costs.
