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. Utah has 540 active community water systems, 48% of the state's 1,133 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 14 Utah systems (1.2%) list groundwater under influence of surface water as their primary source.

Who owns and regulates Monroe City?

EPA lists Monroe City as owned by a local government. The UT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 15 of the 33 active systems in Sevier County (45%) are also owned by a local government.

Does Monroe City have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2025. The violations listed here began between January 2012 and April 2025. By type: 9 monitoring and reporting, 2 monitoring and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (3 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.
