How does Town of Frannie compare with other water systems in Big Horn County?

By EPA's size categories, Town of Frannie is a very small system (500 people or fewer). Big Horn County has 28 active public water systems. Its population served is about 57% below the county average of 371 people per system, and accounts for 1.5% of the 10,387 people reported by systems filed under the county.

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. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 79 Wyoming systems (10%) list purchased surface water as their primary source.

Who owns and regulates Town of Frannie?

EPA lists Town of Frannie as owned by a local government. 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. 12 of the 28 active systems in Big Horn County (43%) are also owned by a local government.

Does Town of Frannie 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 August 1982 and January 2025. By type: 10 monitoring and reporting, 1 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 8 as archived and 4 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.
