Does Minerva Beach Resort have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2007. The violations listed here began between January 2005 and January 2007. By type: 12 monitoring and reporting. The contaminants or rules involved are Lead and Copper Rule, Di(2-ethylhexyl) adipate, Benzo(a)pyrene and Pentachlorophenol. EPA lists 11 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.
