By type: 11 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved is Surface Water Treatment Rule. 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.
