How does Ring Lake Ranch compare with other water systems in Fremont County?

By EPA's size categories, Ring Lake Ranch is a very small system (500 people or fewer). Fremont County has 61 active public water systems. Its population served is well below the county average of 433 people per system, and accounts for 0.1% of the 26,380 people reported by systems filed under the county. Across Wyoming, the 775 active systems average 838 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Ring Lake Ranch is well below that figure.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Wyoming has 352 active transient non-community water systems, 45% of the state's 775 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 585 Wyoming systems (75%) list groundwater as their primary source.

Who owns and regulates Ring Lake Ranch?

EPA lists Ring Lake Ranch 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. 37 of the 61 active systems in Fremont County (61%) are also privately owned.

Does Ring Lake Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in June 2024. The violations listed here began between July 1992 and June 2024. By type: 7 monitoring and reporting, 3 monitoring, 1 reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 7 as archived and 5 as resolved. 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. 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.
