Does Edwardsport Water Utility have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in March 2026. The violations listed here began between January 2024 and March 2026. By type: 5 monitoring, 3 monitoring and reporting, 2 required treatment not met, 1 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 11 as resolved and 1 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. 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.
