Does Seymour Water District have drinking water violations?
EPA's records list 10 violations for this system; 3 are health-based, and the most recent began in July 2025. The violations listed here began between July 1997 and July 2025. By type: 4 public notice, recordkeeping or other, 3 monitoring and reporting, 2 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (4 of them). EPA lists 5 as resolved, 3 as archived and 2 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.
