Does Hadley Dpw Water Division have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in June 2013. The violations listed here began between April 2001 and June 2013. By type: 7 contaminant level above the legal limit and 5 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 10 as archived, 1 as addressed and 1 as resolved. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Addressed means the violation is not resolved or archived and is covered by formal enforcement. 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.
