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, fl uoride may produce an objectionable discoloration of tooth enamel
called fl uorosis, though levels up to 8 mg/L have not been found to be physiologically
harmful.
NOTE: This procedure uses the EPA approved Reagent System for fl uoride found in method
