Water treatment process called potential risk
Maas and Patch, co-directors of the Environmental Quality Institute at UNC-Asheville, said their research showed that a combination of chloramines and fluorosilicic acid, especially with extra amounts of ammonia, increases lead leaching.

Fluoride Chemicals Leach Lead into Water Supplies
Fluoride chemicals, combined with other water additives, pull health-damaging lead from plumbing systems into drinking water, according to University of North Carolina researchers reported a North Carolina newspaper on May 18, 2005 (a). Fluoride is added to water supplies to prevent cavities, not purify it as some believe. A combination of chloramines and fluorosilicic acid, […]

Recent Research on Silicofluorides & Lead
Can water fluoridation increase the levels of lead circulating in a child’s blood? This is the question that has been asked ever since Dartmouth scientist, Dr Roger Masters, and chemical engineer, Myron Coplan, published studies in 1999 and 2000 reporting that exposure to fluoridated water was associated with increased blood lead levels in children surveyed […]

CDC Discusses Fluoridation Chemicals
After many months of waiting, Thomas Reeves, the CDC’s water engineer responsible for overseeing the US fluoridation program, has responded to questions about the chemicals used in fluoridating water. One interesting concession made by Reeves in this letter is that ALL fluoridation chemicals, INCLUDING sodium fluoride, are waste products of the phosphate fertilizer industry. Paul […]

Dartmouth researcher warns of chemicals added to drinking water
In a recent article in the journal NeuroToxicology, a research team led by Roger D. Masters, Dartmouth College Research Professor and Nelson A. Rockefeller Professor of Government Emeritus, reports evidence that public drinking water treated with sodium silicofluoride or fluosilicic acid, known as silicofluorides (SiFs), is linked to higher uptake of lead in children.

Fluoridation Chemicals Have Not Been Safety Tested – Here’s the Proof
Investigations by the National Pure Water Association in England have revealed that — as in the U.S. — the chemicals used to fluoridate drinking water in England have never been tested for safety.

Fluorine recovery in the fertilizer industry – a review.
The fluorine compounds liberated during the acidulation of phosphate rock in the manufacture of phosphoric acid and fertilizers are now rightly regarded as a menace, and the industry is now obliged to suppress emissions of fluorine-containing vapours to within very low limits in most parts of the world. As with any pollution control operation, it is highly desirable for the operator of the fluorine scrubbing operation to find a use or market for the recovered fluorine to help defray at least partially the cost of the operation.

The Phosphate Fertilizer Industry: An Environmental Overview
1. Introduction They call them “wet scrubbers” – the pollution control devices used by the phosphate industry to capture fluoride gases produced in the production of commercial fertilizer. In the past, when the industry let these gases escape, vegetation became scorched, crops destroyed, and cattle crippled. Today, with the development of sophisticated air-pollution control technology, […]

Study Finds Correlation Between Fluorides in Water and Lead Levels
HANOVER, N.H. —Although the dangers of lead poisoning have been known for years, substantial numbers of children continue to suffer from blood lead above danger level of 10 micrograms per deciliter of blood (10µg/dL). A study published this month in the International Journal of Environmental Studies, and led by Roger Masters, Emeritus professor of government […]
