Does Mutiny Bay Riviera have drinking water violations?

EPA's records list 11 violations for this system; 1 is health-based, and the most recent began in October 2003. The violations listed here began between October 1979 and October 2003. By type: 10 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Total coliform bacteria (TCR), Lead and Copper Rule, Arsenic and Mercury. EPA lists 10 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.
