The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 2 as archived, 1 as resolved and 1 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
