Fluoridation - Drinking water - What is in our water?

Fluoridation, using hydrofluorosilicic acid is being used in British Columbia Cities (Prince George) including Alberta Cities, such as Lethbridge and Edmonton. Some of the additional ingredients from other suppliers and confirmed to exist in the hydrofluorosilicic acid sold by Cominco, Trail BC. is listed in the picture, from the 1992, Alberta Report.
"In preparing phosphate fertilizer, the fluorine is released as a gas, silicon tetrafluoride, which becomes hydrofluosilicic acid when the gas is passed through water scrubbers. This liquid waste by-product is then transported from Cominco in Trail, B.C., suppliers to the northwest U.S. and western Canada, to Calgary's two water plants in specially lined tank trucks."
The City of Calgary, once fluoridated is no longer fluoridating their water, voted out by residents.
