*** The best source of information on fluoride levels in community water systems is your local water provider (utility).***
My Waters Fluoride (MWF) provides general information on fluoridated water systems. Please be aware that the MWF site does not contain real-time information. Information is provided by states on a voluntary basis and may not be reported annually. As a result MWF is not inclusive of all states and communities.
