Fluoride and Chlorine


Fluoride and chlorine are added to water during the water treatment process. 

Chlorine is added to kill bacteria and prevent waterborne illness . Our drinking water typically contains 0.2 milligram per liter (mg/l) - 1.6 mg/l of chlorine. Chlorine dissipates over time so fill a pitcher and place it in your refrigerator to remove any chlorine. 

Fluoride has been proven to promote oral health. Fluoride is a mineral that occurs naturally in virtually all waters. Charlotte Water has added fluoride to our water since 1949. Fluoride is added to Charlotte's tap water to a concentration of approximately 0.7 milligrams per liter or less than 1 part per million, as recommended by the American Dental Association.

On April 15, 2011, Charlotte Water officials scaled back fluoride under guidance from Mecklenburg County Health Department. Learn more from Dr. Keener, Director of Mecklenburg County Department of Health.
