Tuesday's Letters to the Editor

Fluoride numbers

EDITOR: Fluoride is most important for cavity prevention during ages six months to 16 years. However, the Sonoma County Water Agency's proposal doesn't cover all children. In 2012, Sonoma County's population was 491,829, and the Water Agency served 350,000 consumers in six cities and the Valley of the Moon. Subtracting 27,600 for three cities not served by the agency leaves 115,000 supplied by private water wells. Some 21.4 percent of the county's population is under 18 years, so 25,000 children wouldn't receive fluoridated water.

For those on Water Agency water, fluoridation has been estimated to reduce cavities in children by between 18 percent and 40 percent (Wikipedia) — relatively low effectiveness. For example, if a child were to get five cavities with non-fluoridated water, the same child would still get three or four cavities with fluoridated water.

In fiscal year 2011-12, the Water Agency delivered 11.2 billion gallons of water to its 350,000 consumers, of whom 80,000 were children. If these children drank six-eight glasses per day, they would have consumed 0.13 percent of the total water, resulting in 99.8 percent of fluoridated water not being used for its intended purpose.

Fluoridation costs are projected in the millions of dollars. There has to be a different approach.

Special treatment?

EDITOR: One can't help but wonder what the charges would have been and how fast the trial would have happened if Sonoma County Supervisor Efren Carrillo were a Republican.
