Does Harding Woods MHP have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in July 2025. The violations listed here began between April 2018 and July 2025. By type: 8 monitoring and reporting, 3 required treatment not met and 1 reporting. The contaminant or rule involved most often is Lead and Copper Rule (11 of them). EPA lists 9 as resolved and 3 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.
