WHERE DOES FLUORIDE COME FROM

 

Low levels of fluoride occur naturally in most sources of drinking water in Canada. Fluoride can occur naturally in surface waters from the deposition of particulates from the atmosphere and the weathering of fluoride-containing rocks and soils, and in groundwater from leaching from rock formations. Fluoride is also introduced in the environment by a variety of human activities such as chemical manufacturing plants and waste ponds; the manufacture of aluminum, steel, glass, enamel, brick, tile, pottery, and cement; production of fluorinated chemical and phosphate fertilizer; and metal casting, welding, and brazing.

Health Canada recently completed its review of the health risks associated with fluoride in drinking water. This review assesses all identified human health risks, taking into account new studies and approaches. Based on this review, the proposed guideline for fluoride in drinking water is currently a maximum acceptable concentration of 1.5 mg/L. This level is currently under review with the view of lowering the it to_______.

During its October 2008 meeting, the Federal-Provincial-Territorial Committee on Drinking Water reviewed the proposed guideline for fluoride in drinking water and gave approval for the guideline and the corresponding Guideline Technical Document to undergo public consultations [ Note: the levels are now being revised downward in 2010]
