Who owns and regulates Sandusky City?

Does Sandusky City have drinking water violations?

Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in July 2025. The violations listed here began between May 1988 and July 2025. By type: 5 monitoring and reporting, 3 required treatment not met, 3 contaminant level above the legal limit and 1 reporting. The contaminant or rule involved most often is Surface Water Treatment Rule (3 of them). EPA lists 8 as resolved and 4 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.
