Debate over fluoride in water resurfaces in San Diego

The pro-F proponents use name calling as a strategy to try and discredit anyone speaking out against adding fluorosilicic acid to the water supply. 2006 NRC EPA Fluoride in Drinking Water reports the system health damage caused by ingesting this chemical, as well as "suspected" damage. Dr. Kathleen Thiessen, a member on the NRC panel for this report, also wrote about the findings in 2011 in a paper called "General Comments on Fluoridation in Drinking Water", where she says: “The proposed HHS recommendation for water fluoridation at 0.7 mg/L is not adequate to protect against known or anticipated adverse effects and does not allow an adequate margin of safety to protect young children, people with high water consumption, people with kidney disease (resulting in reduced excretion of fluoride), and other potentially sensitive population subgroups…. …It is irresponsible to recommend addition of fluoride, or a particular concentration of fluoride to be added, without a comprehensive review of the substances (H2SiF6 or Na2SiF6,) that are actually added. In addition, fluoridation chemicals often contain impurities such as lead and arsenic, for which EPA has set MCLGs of zero (EPA 2006), such that a water supplier is actually adding contaminants for which the ideal maximum amount in drinking water is zero. In summary, it is irresponsible to promote or encourage uncontrolled exposure of any population to a drug that, at best, is not appropriate for many individuals (e.g., those who do not want it, those whose water consumption is high, formula-fed infants, people with impaired renal function) and for which the risks are inadequately characterized and inadequately disclosed to the public. Elimination of community water fluoridation at the earliest possible date would be in the best interest of public health.” http://fluorideinformationaustralia.files.wordp... San Diego should take these chemicals out, and keep them out.
