Children exposed to drinking water containing 4 milligrams of fluoride per liter -- the Environmental Protection Agency's maximum allowable concentration -- risk developing severe tooth enamel fluorosis, says a new National Research Council report. About 200,000 Americans have drinking water with that much fluoride, which comes from both naturally occurring sources and pollution. A majority of the committee that wrote the report also said that people who consume water containing that much fluoride over a lifetime are likely at increased risk for bone fractures. The report does not examine artificially fluoridated water, which contains much less fluoride.
