What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Alaska has 227 active non-transient non-community water systems, 17% 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 Crna Tazlina Health Clinic?
EPA lists Crna Tazlina Health Clinic 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. 8 of the 52 active systems in Valdez-Cordova Census Area County (15%) are also Native American-owned.
Does Crna Tazlina Health Clinic have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2025. The violations listed here began between January 2016 and January 2025. By type: 10 monitoring and reporting, 1 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Chlorine (7 of them). EPA lists 9 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
