Does Mayo Correctional Institution have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in May 2025. The violations listed here began between January 2022 and May 2025. By type: 8 monitoring and reporting, 3 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is E. coli (3 of them). EPA lists 9 as resolved, 2 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.
