2022 Additional Water Quality Info

The accompanying table lists additional regulated (secondary) and non-regulated parameters that were detected in the finished water during 2022.

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.

Additional Regulated (Secondary) and Non-Regulated Parameters

Additional Parameters MCL Maximum Value Range of Results
Aluminum (ug/L) 200 39 25-39
