Does Lake Bruin Water District #1 have drinking water violations?
Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in November 2023. The violations listed here began between February 1994 and November 2023. By type: 8 required treatment not met, 3 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Surface Water Treatment Rule (8 of them). EPA lists 9 as archived, 2 as resolved and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
