Current EPA standards for the maximum amount of fluoride allowed in drinking water do not protect against adverse health effects, says a new report from the National Academies' National Research Council.
The report committee concluded that children exposed to the current EPA maximum allowable concentration of fluoride risk developing dental problems including discoloration, enamel loss, and pitting of the teeth. In addition, warned the committee, people who consume water containing that much fluoride over a lifetime are likely to face an increased risk for bone fractures. The drinking water of over 200,000 Americans contains fluoride in amounts at or above the 4 milligrams per liter (mg/L) currently allowed by the EPA.More details concerning sources and effects of fluoride in drinking water can be found in this National Academies press release.
