PFAS TAP will begin accepting applications on May 1, 2025.
2024 PFAS TAP pilot effort results
Between February and September 2024, PFAS TAP sent out 660 PFAS test kits. By the end of November 2024, 75% of the kits had been returned. Of the 494 tests analyzed to date, 42% of wells tested had levels over the EPA’s MCL for at least one type of PFAS. CDPHE recommended participants apply for the free filter program to reduce their exposure to PFAS.
Test your well, protect your health!
Well water testing and treatment are the best ways to reduce your exposure and risk of health effects from PFAS and other common well contaminants. Getting your well tested is the first step in determining your well water quality. Many water filters are highly effective at removing PFAS and other common well water contaminants. The PFAS Testing and Assistance Program (PFAS TAP) provides access to both.
Colorado residents with a private well can apply for free PFAS testing, and eligible participants can receive free filters that meet NSF standards for removing PFAS and other common well contaminants from drinking water. Testing helps us identify and minimize exposure to PFAS in the area, and develop recommendations on PFAS contamination. This program is available while supplies last.

PFAS TAP partners with local public health agencies and community organizations to perform targeted outreach in counties with a need for testing and filtration resources. In 2025, PFAS TAP is partnering with Gilpin, Grand, and Pueblo counties. Visit your county’s page to learn more about outreach, program updates, and results in your community
- On Feb. 29, 2024, the department and Park County hosted a public meeting to launch the PFAS TAP pilot effort and share information about the program. View the public meeting recording.
- On Nov. 13, 2024, the department and Park County hosted a public meeting to share results from the PFAS TAP pilot effort in Bailey, CO. View the public meeting recording.
Between 2022 and 2023, CDPHE sampling efforts in Bailey (Park County, Colorado) detected PFAS over the EPA’s Maximum Contaminant Level (MCL) in 8 of 15 private wells tested and the untreated groundwater wells of two schools. The schools already had treatment to address PFAS in drinking water.
Based on these preliminary sampling results, CDPHE selected Bailey for the location of the PFAS Testing and Assistance Program (PFAS TAP) pilot effort. In 2024, the department launched PFAS TAP. This pilot program offered Bailey residents free well testing for PFAS and free water filters to income-eligible households with PFAS concentrations over the EPA’s MCL.
