Fluoride in Municipal Water Supplies
Fluoride used in municipal water supplies found contaminated with arsenic
Originally published April 17 2007
Critics of fluoridation gained more ammunition from a report by the U.S. Centers for Disease Control (CDC) stating that trace amounts of arsenic are entering drinking water by means of the chemicals used in fluoridation.
• Water is fluoridated by means of the chemicals sodium fluoride, sodium fluorosilicate, and fluorosilicic acid (FSA). These chemicals are byproducts from the manufacture of phosphate-based fertilizers.
• Trace amounts of contaminants from fertilizer production -- including antimony, barium, beryllium and arsenic -- remain in these fluoridation chemicals and can then be transferred to water.
• Tests by the National Sanitation Foundation discovered arsenic in sample batches of FSA. An increased concentration of between 0.43 and 1.66 parts per billion (ppb) of arsenic in fluoridated water was attributable to FSA.
• The Environmental Protection Agency has set the maximum contaminant level of arsenic in water at 10 ppb.
• Studies have shown, however, that concentrations as low as 1 ppb can increase people's risk of developing bladder or lung cancer.
• Quote: "We're glad the CDC finally admits that arsenic can be found in fluoridation chemicals. But the CDC should go further and list all undesirable chemicals and impurities allowed in the fluoridation chemicals, and make it publicly known so consumers truly can make an informed choice." - Paul Beeber, president of the New York State Coalition Opposed to Fluoridation
