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. Wyoming has 332 active community water systems, 43% of the state's 775 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. 24 Wyoming systems (3.1%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Snake River Mobile Home Park?
EPA lists Snake River Mobile Home Park as privately owned. The WY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 69 of the 112 active systems in Teton County (62%) are also privately owned.
Does Snake River Mobile Home Park have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in October 2025. The violations listed here began between October 2022 and October 2025. By type: 6 monitoring and reporting, 2 contaminant level above the legal limit, 2 required treatment not met and 2 monitoring. The contaminant or rule involved most often is Surface Water Treatment Rule (4 of them). EPA lists 9 as resolved, 2 as archived and 1 as addressed. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
