Does Blue Medina Water have drinking water violations?
EPA's records list 5 violations for this system; 3 are health-based, and the most recent began in December 2025. The violations listed here began between July 1991 and December 2025. By type: 3 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (3 of them). EPA lists 3 as resolved, 1 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
