An anti-fluoride group will continue pressuring the City of Windsor to stop adding fluoride to its drinking water on Wednesday.

Fluoride Free Windsor will make a presentation to the environment and transportation standing committee, which meets at 4:30 p.m.

The group recommends the city stop adding fluoride until toxicology studies on animals and clinical trials on humans are completed; source water monitoring shows fluoride levels do not exceed Canadian water quality guidelines; and it can be demonstrated that the amount of fluoride satisfies the provincial law.

According to Windsor Utilities Commission general manager John Wladarski, the city spends $130,000 dollars each year to add fluoride to its water system. And it's been doing so for 58 years now.

"As a matter of our licence we're compelled to continue the use of fluoride until there's a consensus in the communities we serve that they choose otherwise," Wladarski told CBC News in November 2011.

Fluoride Free Windsor concedes the City of Windsor is licensed to conduct fluoridation but claims the city is not mandated to do so.

Others have stopped fluoridation

Neighbouring communities Lakeshore and Amherstburg have already eliminated fluoride from their drinking water. Tecumseh, which does have fluoride in its drinking water, is studying the practice. The WUC is also studying whether to continue adding fluoride to the city's drinking water.

The WUC admits it adds hydrofluorosilicic acid, a man-made chemical, to its water.

Fluoride Free Windsor claims it's a toxic waste product. The group will raise that point Wednesday.

In January, medical officer of health, Dr. Allen Heimann, appeared before Tecumseh town council with a local dentist to defend water fluoridation.

Heimann noted the Centers of Disease Control calls water fluoridation one of the top 10 public health achievements of the 20th Century.
