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. ​
