Contaminants detected in your water
Shown as % of the federal legal limit, where one exists
Each figure is the average concentration reported for your utility. Where a federal limit exists, we show how close your water is to it; several common contaminants have no federal limit at all. A whole-home or reverse-osmosis system reduces most of these.
