Does Whitmore Lake Elementary have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in September 2009. The violations listed here began between January 1999 and September 2009. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Total coliform bacteria (TCR), Barium, Antimony and Beryllium. EPA lists 9 as resolved and 3 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.
