Perfluorooctanoic acid
9.1ng/L
Each block = 4.0 ng/L federal MCL (2024)
Short answer: Two PFAS, PFHxS and PFOA, are above their federal limits (2024 limits that water systems have until at least 2029 to meet); the water is moderately hard. Anchorage Water and Wastewater Utility serves 221,351 residents.

MOA MUNICIPALITY OF ANCHORAGE (EPA PWSID AK2210906) delivers surface water to 221,351 residents. This report reflects 29 individual PFAS result(s) from the source UCMR5 observations and the latest Lead & Copper Rule 90th-percentile result. The utility's 2025 CCR reports moderately hard water.
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.
The records describe the system. A certified lab test shows what reaches your glass.
PFOA 9.1 ng/L, above the 4 ng/L limit (+1 more PFAS detected)
Each card names which Anchorage findings its current certification covers, and which it doesn't.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Anchorage, PFOA 9.1 ng/L (limit 4 ng/L) and PFHxS 11.2 ng/L (limit 10 ng/L) were measured above their limits in EPA's 2024 testing. MOA MUNICIPALITY OF ANCHORAGE (PWSID AK2210906) has a Purity Score of 57/100 (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.
MOA MUNICIPALITY OF ANCHORAGE (PWS ID AK2210906) is the public water system on record for Anchorage, Alaska, serving about 221,351 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-01-23 to 2023-10-03), PFOA was measured at 9.1 ng/L against a 4 ng/L federal limit and PFHxS was measured at 11.2 ng/L against a 10 ng/L federal limit. Reverse osmosis and filters certified to NSF/ANSI 53 for PFOA/PFOS reduce them at the tap.
Lead is not in Anchorage's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
PurityMap's current record for Anchorage holds 32 findings: 2 above a reference, 1 detected within the reference and 29 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
Anchorage's water is recorded as 6.2 gpg, moderately hard. Hardness is an aesthetic and plumbing characteristic, not a health-based limit.

Start with the hot-or-cold tap check. Where Anchorage Water and Wastewater Utility reported something related, it's shown below.
Lead at Anchorage Water and Wastewater Utility: not detected (90th percentile, 2022–2024 monitoring period). Lead has no taste, so a taste neither shows nor rules it out.
