Does Chamberlain Lake Rest Area have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in November 2025. The violations listed here began between October 1998 and November 2025. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit and 2 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 9 as archived and 3 as resolved. 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. 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.
