How does Cub River Acres compare with other water systems in Franklin County?
By EPA's size categories, Cub River Acres is a very small system (500 people or fewer). Franklin County has 21 active public water systems. Its population served is about 65% below the county average of 515 people per system, and accounts for 1.7% of the 10,819 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. Idaho has 765 active community water systems, 39% of the state's 1,961 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,861 Idaho systems (95%) list groundwater as their primary source.
Who owns and regulates Cub River Acres?

Does Cub River Acres have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in June 2025. The violations listed here began between October 2019 and June 2025. By type: 6 monitoring and reporting, 2 contaminant level above the legal limit, 1 public notice, recordkeeping or other, 1 required treatment not met, 1 reporting and 1 monitoring. The contaminant or rule involved most often is E. coli (3 of them). EPA lists 8 as resolved, 3 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
