Additional Water Quality Information

The accompanying table lists additional regulated (secondary) and non-regulated parameters that were detected in the finished water during 2019.

No adverse health effects are generally associated with the secondary drinking water contaminants. At considerably higher concentrations than the Maximum Contaminant Levels (MCLs), health implications may exist as well as aesthetic degradation. Note that all maximum values are below the MCLs.
