Does Melbourne Waterworks have drinking water violations?
Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in December 2021. The violations listed here began between April 1996 and December 2021. By type: 6 required treatment not met, 3 contaminant level above the legal limit, 2 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Surface Water Treatment Rule (6 of them). EPA lists 7 as archived and 5 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.
