The Sierra Club's official position is that added fluoride should be controlled mainly to limit the damage to wildlife and the ecosystem. http://www.sierraclub.org/policy/conservation/water_fluoridation.aspx
The American Dental Association's position can be found at http://www.ada.org/4045.aspx
which reads, in part, "The American Dental Association unreservedly endorses the fluoridation of community water supplies as safe, effective and necessary in preventing tooth decay. This support has been the Association's position since policy was first adopted in 1950...."
U.S. Surgeon General Regina Benjamin wrote recently at http://www.ada.org/sections/advocacy/pdfs/Surgeon_General.pdf
"...One of water fluoridation’s biggest advantages is that it benefits all residents of a community—at home, work, school, or play—through the simple act of drinking fluoridated water. Where water fluoridation is a community-wide intervention, the benefits are not limited by a person’s income level or their ability to receive routine dental care. It also is a very cost-effective intervention. A lifetime of cavity prevention can be obtained for less than the cost of one dental filling.Fluoridation’s effectiveness in preventing tooth decay is not limited to children, but extends throughout life, resulting in fewer and less severe cavities. In fact, each generation born since the implementation of water fluoridation has enjoyed better dental health than the generation that preceded it. .."
In the light of these and other scientific opinions, I hope that you will solicit a response from the SCWVD to this attack on their water treatment policies.
