Does Village of Diller have drinking water violations?
EPA's records list 7 violations for this system; 6 are health-based, and the most recent began in June 2014. The violations listed here began between February 1991 and June 2014. By type: 6 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 6 as resolved and 1 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.
