Does Patio Rv Park have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in November 2025. The violations listed here began between October 2017 and November 2025. By type: 5 required treatment not met, 4 monitoring and reporting and 3 public notice, recordkeeping or other. The contaminant or rule involved most often is Groundwater Rule (9 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. 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.
