Fluoride shouldn't be in water


Dear editor,

Sixty per cent of Estevan voters agreed to hydrofluorosilicic acid (HFSA) fluoridation in the water in the civic by-election.

HFSA is a smokestack scrubber by-product from the phosphate fertilizer industry. It contains contaminants, as in silicofluoride, fluoride ion, lead, arsenic, mercury, and radioactive material. There are no safe levels of arsenic.

Silicofluorides are almost as toxic as arsenic, and more toxic than lead.

Estevan uses HFSA in the water supply.

According to the Canadian Environmental Protection Act, HFSA is persistent, bio-accumulative toxic. Environment Canada

says HFSA is a hazardous substance. Transport Canada views HFSA as a dangerous good. And the U.S. Environmental Protection Agency [EPA] classifies HFSA as Class 1 hazardous waste

Dr. J. William Hirzy, a senior chemist at U.S. EPA headquarters, once said:

“If (HFSA) gets out into the air, it’s a pollutant; if it gets into the river, it’s a pollutant; if it gets into the lake, it’s a pollutant; but if it goes right straight into your drinking water system, it’s not a pollutant. That’s amazing.”

Hirzy also said: “Our members’ review of the body of evidence over the last 11 years, including animal and human epidemiology studies, indicate a causal link between fluoride/fluoridation and cancer, genetic damage, neurological impairment and bone pathology.”

Rebecca Hanmer, a deputy assistant administrator for water at the EPA, stated:

“In regards to the use of fluosilicic acid as a source of fluoride for fluoridation, this agency regards such use as an ideal environmental solution to a long-standing problem. By recovering byproduct fluosilicic acid from fertilizer manufacturing, water and air pollution are minimized.”

Health Canada says that human health-harm toxicology research has never been conducted on HSFA, and HSFA is not regulated under Canada’s Food and Drugs Act.

The U.S. National Research Council claims fluoride interferes with functions of the brain, and also increases lead accumulation in bone, teeth, and calcium-rich tissues. It binds to calcium, creating dental and skeletal fluorosis, transports heavy metals through the body and through the blood-brain barrier

Finally, Dr. Hardy Limeback, the former president of Canadian Association for Dental Research, once said that “putting hydrofluorosilicic acid from smoke stack scrubbers to fluoridate the water ... was the breaking point. [I] advocate that we stop putting toxic waste in Canadian water supplies.”

HFSA is absorbed through inhalation, swimming at areas like playparks, and bathing. We water gardens with HFSA.

I propose those who still think HFSA in water is safe should agree to drink only tap water for themselves and their families.

The mayor and councilors should know if any “yes” voters have changed their mind.
