The contaminant or rule involved most often is Surface Water Treatment Rule (3 of them). EPA lists 9 as resolved, 2 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.
