Natural Fluoride (CaF2) vs Chemical Fluoride

Clarification on the two types of fluoride to which ADH health officials keep referring:

There are two main forms of fluoride in the world today. One type is the natural version of fluoride that is naturally found in the environment, and it is not that harmful to the environment or to us. The natural version of fluoride found in the soil is known as calcium fluoride (CaF2). The other version is an industrial synthetic called sodium fluoride, a synthetic toxic waste that is known to cause cancer.
Manufacturers of sodium fluoride manipulated their data to create the illusion that sodium fluoride is not toxic. They then used this data to convince political leaders to allow them to add sodium fluoride into consumer products, pesticides and drinking water. (You may have heard it said: “The solution to pollution is dilution.” This is dangerous!)
The fluoride chemicals being used to fluoridate drinking water are: hydrofluorosilicic acid, sodium fluorosilicate, and sodium fluoride. Unlike the fluoride compounds found in toothpaste or supplements, water fluoridation chemicals are not pharmaceutical grade quality. They are, instead, unpurified industrial by-products that are collected in the air pollution control systems of certain industries.
Calcium fluoride, which occurs naturally, is not included in the Poisons List. This is because natural fluoride is not very soluble in water. Substances used in the artificial fluoridation of the public water supply are *sodium fluoride (NaF), sodium fluorosilicate (Na2SiF6), and hydrofluosilicic acid (H2SiF6). These artificial fluorides are highly soluble in water.
