Mount Pleasant City Commission votes to reduce amount of fluoride in city water supply
Editor’s Note: This is the first story in a series about fluoride in Mount Pleasant water.
The Mount Pleasant City Commission Monday voted four-to-two to temporarily reduce the amount of sodium fluoride added to the city’s water supply to the lowest level possible, consistent with the language of the 2005 ballot.
The temporary decrease will remain in effect until the Environmental Protection Agency releases findings from an ongoing study researching a safe level of water fluoridation.
The reduction was recommended by the Fluoride Task Force, headed by Commissioner Kathleen Ling and consisting of four other city residents representing a range of opinions regarding water fluoridation.
“The EPA is in the middle of doing a re-assessment,” Ling said. “It seems to us premature to go back to the ballot while we’re waiting for the EPA to finish their study.”
Ling said the task force was created to address whether water fluoridation is effective, safe and if its usage has any significant ethical or legal issues.
The task force members spent nearly a year researching documentation from various experts and organizations regarding the effects of the ingestion of fluoride.
“There do appear to be a number of possible health risks,” Ling said. “We now know it is not ingesting it that strengthens your teeth, it’s topical application.”
Based on reports reviewed by the task force, overexposure to fluoride causes dental fluorosis, which includes symptoms like discoloration of the teeth.
A National Research Council Report published in March 2006 linked fluoride to an increase in bone fractures and skeletal fluorosis, bone cancer, adverse brain development effects and decreased thyroid function, Ling said.
However, she said the American Dental Association and Centers for Disease Control continue to endorse water fluoridation.
Mount Pleasant’s natural fluoride level in city water is 0.4 parts per million, or milligrams per liter. Currently, the city adds fluoride to reach 0.7 ppm, which is within current guidelines of 0.7 to 1 ppm as recommended by the ADA and CDC.
Ling said she expects the fluoride levels to be reduced to somewhere between 0.4 and 0.5 ppm until the EPA’s study is released.
Not all are happy
However, some meeting attendants were disturbed by the commission’s decision.
Carol Hanba, oral health coordinator for the Mid Michigan District Health Department and dental hygienist of more than 30 years, was frustrated.
“I see first hand the disparities of dental health in our children. I think what you did tonight did harm,” she said. “Dentists go to college for nine years to learn what they know.”
But Mount Pleasant resident Jeremy Hart was pleased with the commission’s decision.
“Fluoride affects so much more than your teeth,” he said. “If people want it, fine, but don’t force it on me if I don’t want it.”
Sharyl Majorski, member of the Fluoride Task Force and chemistry lab coordinator at Central Michigan University, said more research is needed on the effects of fluoride ingestion.
“Any chemical can be safe, any chemical can be dangerous,” she said. “This is one that deserves more attention.”
The City Commission also appointed Nancy English to fill prior Commissioner Jeffrey Palmer’s vacant seat.
English is currently a commissioner for the Mount Pleasant Planning Commission.
