Is My Water Fluoridated?
Access official CDC water fluoridation data for public water systems nationwide. Search by address and zip code to monitor fluoride levels, system coverage, and population data for your town's water system.
Water systems labeled "Not Fluoridated" may still display fluoride levels due to naturally occurring fluoride in the water source, rather than added during treatment. The WHO recommends levels not exceed 1.5 mg/L, while the EPA suggests 2 mg/L as optimal, with recent studies noting potential neurodevelopmental concerns at higher levels.
