How does Wales Water System compare with other water systems in Nome Census Area County?
By EPA's size categories, Wales Water System is a very small system (500 people or fewer). Nome Census Area County has 17 active public water systems. Its population served is well below the county average of 607 people per system, and accounts for 1.7% of the 10,325 people reported by systems filed under the county. Across Alaska, the 1,322 active systems average 653 people each. Nationally, the average active community water system reports serving 6,703 people, so Wales Water System is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. 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 Wales Water System?
EPA lists Wales Water System as Native American-owned. The AK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 16 of the 17 active systems in Nome Census Area County (94%) are also Native American-owned.
Does Wales Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2025. The violations listed here began between July 2024 and October 2025. By type: 6 monitoring and reporting, 3 monitoring, 2 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Combined Uranium (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.
