The contaminants or rules involved are Total coliform bacteria (TCR), Lead and Copper Rule and Gross alpha (excluding radon and uranium). EPA lists 2 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. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
