Fluoride occurs naturally in most water supplies and may be added in larger concentrations above the natural background in order to promote dental health. High levels of fluoride are known to cause health problems. Fluoride concentrations in municipal water supplies were measured using an ion-selective electrode. Fluoride was detected in 23 of the 25 samples collected, all sites reported a concentration well below EPA’s standard of 4 . 4. th. Grade. April/ May 2012. The State of Texas. State Capitol: Austin.
