Does Stonebridge Gardens MHP have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in August 2025. The violations listed here began between December 2020 and August 2025. By type: 11 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Groundwater Rule (4 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.
