Does Cabinet Mountains Water Dist have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in September 2018. The violations listed here began between January 1997 and September 2018. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 8 as archived and 4 as resolved.
