What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Ohio has 1,028 active community water systems, 27% of the state's 3,854 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 114 Ohio systems (3%) list purchased groundwater as their primary source.
Who owns and regulates College Corner Water?

The OH 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 Preble County (43%) are also owned by a local government.
Does College Corner Water have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2025. The violations listed here began between May 1990 and July 2025. By type: 8 monitoring and reporting, 2 reporting, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Lead and Copper Rule Revisions (3 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.
