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 4500-F-D, 18th Edition of Standard Methods, page 1-27.
