Does Mbnf-Ryan Park Cg have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in June 2022. The violations listed here began between July 1997 and June 2022. By type: 7 monitoring and reporting, 4 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 7 as archived and 5 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.
