Does Diamond Point have drinking water violations?
EPA's records list 11 violations for this system; 3 are health-based, and the most recent began in May 2023. The violations listed here began between October 1979 and May 2023. By type: 8 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 7 as archived and 4 as resolved.
