Does Sans End Rv Park have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between January 2024 and October 2025. By type: 10 monitoring and reporting and 2 reporting. The contaminants or rules involved are Revised Total Coliform Rule, Nitrate, Lead and Copper Rule Revisions and 2,3,7,8-TCDD (dioxin). 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. 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.
