Does Sand Island Recreation Site have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in December 2025. The violations listed here began between March 2017 and December 2025. By type: 6 monitoring, 5 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (10 of them). EPA lists 7 as resolved and 5 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.
