Does Grand Lake Golf Course 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 2008. The violations listed here began between January 2005 and January 2008. By type: 12 monitoring and reporting. The contaminants or rules involved are Nitrate, Total coliform bacteria (TCR), Beryllium and Nickel. 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.
