Does Avonwheel Estate 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 February 2023. The violations listed here began between January 2017 and February 2023. By type: 7 monitoring and reporting, 3 required treatment not met, 1 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Groundwater Rule (7 of them). 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.
