By type: 6 public notice, recordkeeping or other and 6 monitoring. The contaminant or rule involved most often is Public Notice (6 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
