By type: 7 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Arsenic (3 of them). EPA lists 6 as resolved and 2 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.
