Does Newark have drinking water violations?
EPA's records list 3 violations for this system; 2 are health-based, and the most recent began in July 1996. The violations listed here began between June 1977 and July 1996. By type: 1 contaminant level above the legal limit, 1 required treatment not met and 1 monitoring and reporting. 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 archived and 1 as resolved. 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. 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.
