The contaminants or rules involved are Consumer Confidence Rule, Haloacetic acids (HAA5), Revised Total Coliform Rule and Chlorine. EPA lists 3 as resolved, 2 as archived and 1 as unaddressed. 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.
