Surprising Source of Arsenic in Your Drinking Water—Will EPA Take Steps to Protect Your Health?
By Dr. Mercola
- While naturally-occurring arsenic in groundwater is one of the most common sources of exposure, hydrofluorosilicic acid (fluoride) added to drinking water is commonly contaminated with toxic arsenic
- According to recent research, diluted fluorosilic acid adds, on average, about 0.08 ppb of arsenic to your drinking water
- Low-level chronic exposure to arsenic can lead to a wide variety of health problems, including chronic fatigue, reproductive problems, reduced IQ and other neurological problems, and various cancers
- As petition urges the EPA to change the source of fluoride in US drinking water, as the most commonly used form, hydrofluorosilicic acid, increases lung and bladder cancer risk
- Switching from hydrofluorosilicic acid to pharmaceutical-grade fluoride could save the US $1-6 billion annually and prevent an estimated 1,800 cases of lung and bladder cancer
Pure water is one of the most important foundations for optimal health. Unfortunately, most tap water is far from pure, containing a vast array of disinfection byproducts, chemicals, heavy metals and even pharmaceutical drugs. Fluoride and arsenic are two prime examples of hazardous water contaminants.
Not only is the level of arsenic in US tap water high due to natural groundwater contamination,1 the most commonly used form of fluoride added to water supplies also tends to be contaminated with arsenic. As reported by the featured article:2
“In early August, the Environmental Protection Agency is set to decide on a petition to change the source of fluoride in US drinking water.
Currently, the source of fluoride in most public water supplies is fluorosilicic acid, according to government records. The petition calls for the EPA to instead require the use of pharmaceutical-grade sodium fluoride in water fluoridation, which is the addition of fluoride to drinking water for the purpose of preventing cavities.
Fluorosilicic acid is often contaminated with arsenic, and recent research has linked the arsenic from fluorosilicic acid in drinking water to as many as 1,800 extra cases of cancer yearly in the United States...”
The petition3 was submitted by William Hirzy, a chemistry researcher at the American University in Washington, D.C. Hirzy previously worked at the EPA for 27 years.
His team recently published a study entitled: "Comparison of hydrofluorosilicic acid and pharmaceutical sodium fluoride as fluoridating agents – a cost-benefit analysis", in the journal Environmental Science & Policy.4
According to their estimation, switching the type of fluoride used to pharmaceutical-grade sodium fluoride would reduce the amount of inorganic arsenic contamination in drinking water by 99 percent!
