By type: 12 monitoring and reporting. The contaminants or rules involved are Toluene, 1,2-Dichloroethane, Carbon tetrachloride and Tetrachloroethylene. 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.
