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

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,446 Ohio systems (89%) list groundwater as their primary source.
Who owns and regulates Lewisburg South?
EPA lists Lewisburg South as owned by a local government. 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 Lewisburg South have drinking water violations?
Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in January 2025. The violations listed here began between April 2005 and January 2025. By type: 8 contaminant level above the legal limit and 4 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 of them). EPA lists 11 as resolved and 1 as archived. 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.
