Drinking Water Quality Results – Not-Detected Parameters

The following water quality parameters were monitored in treated drinking water at the water treatment plants, but two-year median values are below laboratory detection limits.

In a few cases, the parameter was only monitored at one of the water treatment plants and the two-year median result was non-detect.
