The purpose of this Fluoridation Guidance Manual is to assist public water systems as well as public water system operators in the adjustment and maintenance of fluoride levels to the optimal level within the specified range. The manual intends to accomplish this by helping PWS and PWS operators better understand what is required of them by rule and by providing information resources, contact information and certain procedures.

Every fluoridating PWS should have and maintain a copy of this Manual as well as copies of the technical manuals and guides referenced herein. Hard copy updates and revisions will be supplied as the need arises and this manual is available in electronic format upon request.
