The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 4 as archived and 3 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.
