Is there PFAS in Golden Heart Utilities water?

Some. At least one sample reached an EPA limit, but the average at every sampling point stayed below it.

Golden Heart Utilities Serves 78,324 people · 2 PFOA samples from 1 sampling point · Jul 2024 to Jan 2025 One or more samples at an EPA limit
PFOA Perfluorooctanoic acid 2.7 ppt avg · max 5.4
EPA 4
PFOS Perfluorooctanesulfonic acid not detected
EPA 4
PFHxS Perfluorohexanesulfonic acid 6.9 ppt avg · max 8.8
EPA 10
Hazard index GenX, PFBS, PFNA, PFHxS combined 0.7 avg · max 0.9

Also detected, no federal limit: PFHxA, PFPeA.

Averages are for the worst sampling point, with non-detects counted as zero. Source: EPA UCMR 5.

Golden Heart Utilities is a public water system drawing on groundwater, based in Fairbanks, Alaska, serving about 78,324 people, including Fairbanks, Eielson Afb, North Pole, Salcha, Two Rivers, Rampart. Under EPA's Fifth Unregulated Contaminant Monitoring Rule it was tested for 29 PFAS and lithium 2 times across 1 sampling point between Jul 2024 and Jan 2025.

What the EPA limits mean here

In April 2024 EPA set enforceable limits of 4 ppt for PFOA and PFOS, 10 ppt each for PFHxS, PFNA and GenX, and a hazard index of 1 for mixtures. Utilities were given until 2029 to comply. In May 2026 EPA proposed keeping only the PFOA and PFOS limits and moving that deadline to 2031. Until that proposal is final, the 2024 limits stand.

Compliance is judged on a running annual average at each entry point, so we show the average at this system's worst sampling point next to its single highest result. UCMR 5 results do not by themselves put a utility in or out of compliance.

What you can do at home

Two routes work for PFAS. For drinking and cooking water only, a reverse osmosis system certified to NSF/ANSI 58 with a PFOA/PFOS reduction claim is the cheapest proven option. To treat every tap and shower, a whole-house carbon system with enough contact time works, but check that the maker has PFAS test data, not just a marketing claim. See the best filters for PFAS and how PFAS removal works.
