The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (10 of them). EPA lists 10 as resolved, 1 as unaddressed and 1 as archived.

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.
