Does Silver Bay Harbor of Refuge have drinking water violations?

Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in August 2024. The violations listed here began between July 2001 and August 2024. By type: 7 monitoring and reporting, 3 monitoring and 2 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 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.
