Nearly half the residents have gnarled bones, stooped backs and deformed teeth. It is a major cause of physical disabilities for decades. Millions of people in rural India drink from pumps that draw water from deep below ground, where it often absorbs hazardous levels of the chemical from fluoride-bearing rocks.
