What does “community water system” mean?

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 Caribou Acres?

Does Caribou 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 September 2023. The violations listed here began between September 2001 and September 2023. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit and 2 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 9 as archived and 3 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.
