Cranbrook residents Brad Brehm and Brian Kostiuk started the process of looking at Cranbrook's fluoridation of the water supply two years ago.
They went in front of city council and requested a review of the fluoridation of Cranbrook's water supply.
"We did request, based on the scientific evidence that we presented them, that they discontinue the fluoridation of Cranbrook's water supply," Brehm said.
A year after that they met Kevin Millership who brought a lawsuit against the city for damages for dental fluorosis caused by fluoride in the water supply, which lead to a settlement, the terms of which the City has not commented on.
Brehm said at the time they met with council there was interest in the subject, but it didn't seem to lead anywhere.
"So we're pleased we did end up connecting with Kevin," he said.
At that time they were the We Are Change Cranbrook group, which focused on other issues as well as fluoridation.
After the meeting they created the current group called Fluoride Free Cranbrook.
The group's Facebook page includes 50 members.
They expect that there will be a lot more people joining the movement over the next few months.
In September, the group will be bringing in Dr. James Beck, MD to do a presentation on the medical and scientific facts about the dangers of fluoridation.
Dr. Beck, an expert on fluoride, co-authored the book The Case Against Fluoride: How Hazardous Waste Ended Up in Our Drinking Water and the Bad Science and Powerful Politics that Keep it There.
Brehm said he got the feeling that council felt that since its current members didn't put in the fluoride measures in the first place, it shouldn't be on them to remove it.
Brehm said he'd personally researched this issue for six years or so before bringing it in front of council.
"I'm very certain about the dangers of fluoridation," he said.
"I'm not talking about when you go to the dentist. I'm not talking about it in your toothpaste. I'm merely talking about it being added to the municipal water supply."
He said he is not against fluoride in general, but rather against it being added to the water without his consent.
"Because it does not give me or my family the choice of whether or not I'm consuming that chemical," he said.
Cranbrook is one of only six municipalities in B.C. that still fluoridates its water supply. The others are Fort St. John, Prince George, Prince Rupert, Sparwood and Terrace.
Brehm said he hopes they can get the information to people.
"I honestly believe that if the average person has the information, most people will recognize that there are too many dangers; there's not enough of a safety factor to continue doing it," he said.
At the meeting two years ago, Coun. Sharon Cross also noted the city spends $30,000 a year to fluoridate the water.
In March, Millership, who lives in Slocan, launched a class action lawsuit against the City of Prince George.
