Two thirds of the U.S. municipal water supply is artificially fluoridated in an effort to prevent tooth decay. But fluoridation additives in tap water are not the same form of fluoride as found in toothpaste. Typically, water is fluoridated with fluorosilicic acid (FSA) or its salt, sodium fluosilicate, collectively referred to as fluorosilicates. In contrast, fluoride in toothpaste is usually in form of simple sodium fluoride salt, NaF.
Fluorosilicates have a unique affinity for lead. In fact, lead fluorosilicate is one of the most water-soluble forms of lead. When fluorosilicates in water pass through lead-containing pipes and metal fixtures, the fluorosilicates extract high levels of soluble lead from leaded-brass metal parts. Researchers have found that the mixture of the two chemicals: disinfectant (whether chlorine or chloramine) with fluorosilicic acid has a drastically increased potency, leaching amazingly high quantities of lead. This lead goes into our drinking water and right on into our bodies, where they wreak havoc by poisoning our heart, kidneys and blood, causing irreversible neurological damage and impairing reproductive function.
Chlorine and chloramine are probably here to stay for some time. On the other hand, fluoride, or, specifically, water fluoridation with fluorosilicates, is quite dispensable. There is clear evidence that fluoride dental products significantly reduce the incidence of cavities. In contrast, a substantial and growing body of peer-reviewed science suggests that ingesting fluoride in tap water does not provide any additional dental benefits other than those offered by fluoride toothpaste and may present serious health risks.
In case of fluoridation and chloramines, what emerges at the end of the pipe (our faucets) is a potentially highly hazardous mixture of fluorosilicates, lead, and residual levels of disinfectants. To protect the health of our families today, we can buy a water filters to remove heavy metals and disinfection byproducts from my drinking water with a simple pitcher filter.
Water treatment chemistry is still insufficiently understood by scientists and specific water quality outcomes depend on the particular chemical interactions found in each water treatment and distribution system. To protect the health of the entire nation, we really need to consider if our current methods of water treatment can withstand scientific scrutiny, or whether they should be re-assessed so as to provide safe, healthy tap water to all Americans.

Among other activities, the New York Urban League has scheduled an Open House and Neighborhood Day; the Charleston, S.C. affiliate will receive a proclamation from the mayor; and the Urban League of Columbus, GA, will rally to get out the vote. The Urban League of Chattanooga, TN, has a full day of activities planned, including a scholar’s fair, a Federal Reserve Bank listening tour and an open house.

The states participating in the Regional Greenhouse Gas Initiative (RGGI) today published the first quarter 2010 report on the secondary market for RGGI carbon dioxide (CO2) allowances. The report was prepared by Potomac Economics, the independent market monitor retained to evaluate the RGGI CO2 allowance market.
The Report on the Secondary Market for RGGI CO2 Allowances: First Quarter 2010 is part of Potomac’s ongoing monitoring of the RGGI auctions and the secondary markets where CO2 allowances trade. The report, which addresses the period from January to April 2010, is based on data reported to the Commodity Futures Trading Commission (CFTC), the Chicago Climate Futures Exchange (CCFE), and the New York Mercantile Exchange (NYMEX), as well as other data.
