Does Focus Study Center have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2025. The violations listed here began between April 2000 and August 2025. By type: 6 monitoring and reporting, 3 reporting and 3 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (6 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.
