Profile America — Wednesday, January 4th.  At the beginning of this month 50 years ago, the first fluoridation law in the U.S. went into effect.  Connecticut required fluoridation of public water supplies serving 20,000 or more population, to combat tooth decay. The requirement was extended to the whole state later that year.  Water fluoridation began in 1945, when the cities of Newburgh, New York, and Grand Rapids, Michigan, began adding sodium fluoride to their public water systems. Today in the U.S., there are 1.2 million miles of water supply lines.  Some 102-million of America’s 116-million occupied housing units are connected to public water lines.  As most urban areas fluoridate their water, some three quarters of the U.S. population have such treated community water on tap.  You can find more facts about America from the U.S. Census Bureau online at
