Does Interlochen Plaza East have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2019. The violations listed here began between January 1999 and January 2019. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, Nitrate, Antimony and Mercury. EPA lists 10 as archived and 2 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.
