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. California has 1,466 active non-transient non-community water systems, 20% of the state's 7,479 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 609 California systems (8.1%) list surface water as their primary source.
Who owns and regulates Junction City School?
EPA lists Junction City School as privately owned. The CA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 27 of the 42 active systems in Trinity County (64%) are also privately owned.
Does Junction City School have drinking water violations?
EPA's records list 11 violations for this system; 7 are health-based, and the most recent began in January 2025. The violations listed here began between June 1993 and January 2025. By type: 7 required treatment not met, 2 monitoring and 2 monitoring and reporting. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (7 of them). EPA lists 7 as resolved and 4 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.
