FLUORIDE INTRODUCTION
Fluoride may occur naturally in some ground waters or it may be added to public
drinking water supplies to maintain a 1.0 mg/L concentration to prevent dental cavities.
At higher concentrations, fluoride may produce an objectionable discoloration of tooth
enamel called fluorosis, though levels up to 8 mg/L have not been found to be
physiologically harmful.
