Does Hen House have drinking water violations?
EPA's records list 3 violations for this system; all are health-based, and the most recent began in July 1999. The violations listed here began between July 1992 and July 1999. By type: 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 2 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. 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.
