Homes, apartments and mobile-home parks are served by these. Alaska has 406 active community water systems, 31% of the state's 1,322 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,054 Alaska systems (80%) list groundwater as their primary source.
Who owns and regulates Unalakleet City Water Supply?

Does Unalakleet City Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in March 2026. The violations listed here began between January 2024 and March 2026. By type: 5 monitoring and reporting, 4 required treatment not met and 3 monitoring. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (5 of them). EPA lists 10 as resolved and 2 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
