Fluoride
Fluoride is a natural mineral that can get into water from natural sources or from being added during the treatment process. In the City's water, there's already a little fluoride from nature. But during the water treatment, more fluoride is added. This is to help keep teeth strong and prevent certain health problems. Adding fluoride is also required by the State of Delaware Office of Drinking Water.

Fluoride
In Delaware, there's a Maximum Contaminant Level (MCL) for fluoride, set at 2.0 parts per million (ppm). MCLs tell us about certain things in the water that might affect how it tastes, smells, looks, or feels. If the average fluoride levels in the water go over Delaware's MCL, the City has to tell customers. Read more from the Office of Drinking Water here.
