Does Tnf-Wild Plum Cg have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2002. The violations listed here began between November 1983 and July 2002. By type: 11 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved is Total coliform bacteria (TCR). EPA lists 11 as archived 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. 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.
