Does Centerville Municipal Waterworks have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in June 2002. The violations listed here began between October 1990 and June 2002. By type: 9 monitoring and reporting, 2 contaminant level above the legal limit and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 11 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.
