How does Metlakatla compare with other water systems in Alaska?

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. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 150 Alaska systems (11%) list surface water as their primary source.
Who owns and regulates Metlakatla?
EPA lists Metlakatla as Native American-owned. The EPA Region 10 is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.
Does Metlakatla have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in March 2026. The violations listed here began between April 2025 and March 2026. By type: 5 monitoring and reporting, 4 public notice, recordkeeping or other and 3 required treatment not met. The contaminant or rule involved most often is Public Notice (4 of them). EPA lists 5 as resolved, 5 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
