Does Seminole Co. Rwd #1 have drinking water violations?
Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in October 2025. The violations listed here began between October 2023 and October 2025. By type: 9 contaminant level above the legal limit, 1 reporting, 1 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (10 of them). EPA lists 9 as archived and 3 as resolved. 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. 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.
