Does Rush City have drinking water violations?
EPA's records list 8 violations for this system; 3 are health-based, and the most recent began in May 2025. The violations listed here began between December 1991 and May 2025. By type: 4 monitoring and reporting, 3 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 5 as resolved and 3 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.
