Does Diamond Oil #103 have drinking water violations?
EPA's records list 11 violations for this system; 2 are health-based, and the most recent began in January 2021. The violations listed here began between May 1993 and January 2021. By type: 9 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 8 as archived and 3 as resolved.
