Fluoride is not required in all drinking water sources in the united states, but the levels of fluoride in water are regulated by several government agencies starting in 1962, the united states public health service (phs) recommended that public water supplies contain between 07 and 12 milligrams of fluoride per liter (mg/l) of drinking.
- The first studies about positive effects were conducted in 1945 with systemic fluoridation of drinking water in four american cities (grand rapids, evanston, brantford and newberg), where 1 mg of fluoride per liter was added to drinking water.
- We adjust the naturally occurring level of fluoride in our drinking water in a responsible, effective, and reliable manner that includes monitoring and controlling fluoride levels as mandated by state and/or federal laws, regulations and recommendations.
- For the past 70 years, fluoride has been added to public water supplies to bring fluoride levels up to the amount necessary to help prevent tooth decay community water fluoridation is like drinking milk fortified with vitamin d or eating bread and cereals enriched with folic acid.
In 1975, following passage of the safe drinking water act (sdwa), the epa set the maximum contaminant level (mcl) for fluoride at 14-24 ppm, which is just twice the level of fluoride added to water in artificial fluoridation programs (07 to 12 ppm. That's because fluoride, a substance found naturally in water, plays an important role in healthy tooth development and cavity prevention about fluoride fluoride, which exists naturally in water sources, is derived from fluorine, a common element in the earth's crust.
