By type: 7 monitoring and reporting, 3 public notice, recordkeeping or other and 2 monitoring. The contaminant or rule involved most often is Nitrate (7 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.
