Does Ephraim City have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2018. The violations listed here began between January 1993 and October 2018. By type: 10 monitoring and reporting, 1 monitoring and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Surface Water Treatment Rule (3 of them). EPA lists 9 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.
