By type: 12 monitoring and reporting. The contaminants or rules involved are Trichloroethylene, Barium, 1,2-Dichloropropane and Antimony. EPA lists 10 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.
