[6] In 2015, the U.S. Food and Drug Administration (FDA), based on the recommendation of the U.S. Public Health Service (PHS) for fluoridation of community water systems ...
Defluoridation is the downward adjustment of the level of fluoride in drinking water. Worldwide, fluoride is one of the most abundant anions present in groundwater. Fluoride is more present in groundwater than surface water mainly due to the leaching of minerals. Groundwater accounts for 98 percent of the earth's potable water. [1]
The research had two goals: (1) to warn communities with a high concentration of fluoride of the danger, initiating a reduction of the fluoride levels in order to reduce incidence rates of fluorosis, and (2) to encourage communities with a low concentration of fluoride in drinking water to add fluoride in order to help prevent tooth decay. By ...
In 2015, the U.S. Public Health Service, under the Department of Health and Human Services, set the optimal level of fluoride in water at 0.7 milligrams per liter — a level that, after decades ...
Some 53% of these water systems have fluoride concentration within recommended levels - between 0.7mg per liter and 1.2mg per liter. Just under half of them (47%) have fluoride concentration under ...
Fluoride pollution from various industrial emissions can also contaminate water supplies.
