Real EPA measurements of fluoride for Kansas water systems — Six-Year Review compliance samples 2012–2019 (historical). Methodology
Every Kansas system with a fluoride result in EPA's data, sorted by level. Averages of 2012–2019 finished-water samples, non-detects counted as zero — historical, not today's tap.

While fluoride at low levels is added to prevent tooth decay, excessive exposure can cause problems. Dental fluorosis causes white spots on teeth in children. Skeletal fluorosis from long-term exposure to very high levels can cause joint stiffness and bone damage. Studies have suggested potential links between high fluoride levels and thyroid function issues.

Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,fluoride has been detected in 19 Kansas water systems. The average level across all tested cities is 14% of the EPA Maximum Contaminant Level (MCL), with the highest detection at 28.6% of the limit.
The EPA MCL for fluoride is 4.0 mg/L, with a secondary standard of 2.0 mg/L. The EPA MCL for fluoride is 4 mg/L. This limit is set to protect public health based on available scientific evidence about the contaminant's health effects.
19 Kansas cities have fluoride detected in their water supply. All tested cities are within EPA safety limits.
Dental fluorosis (tooth discoloration), skeletal problems at high levels, potential thyroid effects. The most vulnerable groups include children during tooth development and people with kidney disease.
The most effective methods for removing fluoride include Reverse Osmosis, Distillation, Activated Alumina. Look for filters certified by NSF/ANSI for fluoride reduction.
The EPA Maximum Contaminant Level (MCL) for fluoride is 4 mg/L.The EPA MCL for fluoride is 4.0 mg/L, with a secondary standard of 2.0 mg/L.
This page shows what Kansas utilities reported for fluoride. It cannot tell you what is coming out of your own tap: utility samples are taken across a whole system and averaged, levels vary by address and season, and anything picked up after the water leaves the main never appears in their report.
