Track record
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.

Questions
Frequently asked questions
Is Fairbanks tap water safe to drink?
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Fairbanks, PFOA 5.4 ng/L was measured above the 4 ng/L federal limit in EPA's 2024 testing; the lead 90th-percentile result was 2.4 µg/L against the 15 µg/L action level. GOLDEN HEART UTILITIES (PWSID AK2310730) has a Purity Score of 69/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
Who provides tap water in Fairbanks?
GOLDEN HEART UTILITIES (PWS ID AK2310730) is the public water system on record for Fairbanks, Alaska, serving about 78,324 people. Confirm the utility on your water bill before acting on a specific finding.
Where does Fairbanks get its drinking water?
Groundwater (primary source of record in EPA SDWIS).
Are PFAS "forever chemicals" in Fairbanks's water?
Yes. In EPA's UCMR 5 testing (2024-07-01 to 2025-01-17), PFOA was measured at 5.4 ng/L against a 4 ng/L federal limit. PFHxA (3.7 ng/L, below the 400,000 ng/L state limit) and PFHxS (8.8 ng/L, below the 10 ng/L federal limit) were also detected. PFPeA (3.3 ng/L) was also detected; it has no federal or state limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Is there lead in Fairbanks's tap water?
GOLDEN HEART UTILITIES's most recent lead 90th-percentile result (2023–2025) was 2.4 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
What does the latest Fairbanks water report show?
PurityMap's current record for Fairbanks holds 31 findings: 1 above a reference, 3 detected within the reference, 1 detected with no limit and 26 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.

Methodology: how we analyze water. Prepared with AI assistance and reviewed by the PurityMap Editorial Team before publication.
Something off with your water's smell, color or taste?
Start with the hot-or-cold tap check. Where Golden Heart Utilities reported something related, it's shown below.
- Rotten-egg smell
- Cloudy or milky water
- Chlorine smell
- Brown or yellow water
- Metallic taste
Lead at Golden Heart Utilities: 2.4 µg/L (90th percentile, 2023–2025 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
