Does Ray County Pwsd 1 have drinking water violations?
EPA's records list 5 violations for this system; 2 are health-based, and the most recent began in July 2025. The violations listed here began between November 1992 and July 2025. By type: 2 contaminant level above the legal limit, 1 reporting, 1 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 2 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
