The water in Strathcona County will have a little less fluoride, following EPCOR’s decision to reduce the parts per million to keep in line with Health Canada’s recommendation.

The fluoride in the water will be reduced from 0.8 ppm to 0.7 ppm because of the increased fluoridation levels in toothpaste. Health Canada states the maximum fluoride levels are 1.5 ppm.

Health Canada states on its website that 0.7 ppm of fluoride in water is the optimal balance between avoiding skeletal fluorosis and fighting off dental caries, also known as tooth decay.

EPCOR’s E.L. Smith Water Treatment Plant in Edmonton treats Strathcona County’s drinking water. According to EPCOR, the North Saskatchewan River has about 0.15 ppm of fluoride naturally.

Alberta Health Services requested the change from EPCOR, while EPCOR requires approval from Alberta Environment for any changes.

The lowering in fluoride levels is currently in effect. EPCOR has been fluoridating water since 1967.

Skeletal fluorosis, a bone disease caused by excess fluoride, is a known concern when exposed to 10 mg/day after 10 or more years, according to Health Canada.

Health Canada said the bulk of evidence suggests there is no link between fluoride and cancer. The organization also states there is significant concern about the studies on the effect of fluoride on Intelligence Quotient.

According to the Fluoride Action Network, a group against the use of fluoride, there have been more than 2,500 medical professionals sign against the use of fluoride. The group cites several studies citing health effects caused by fluoride.
