New Fluoride Concentration Levels for DMWW Finished Water

Effective Monday, January 10, Des Moines Water Works (DMWW) will adjust levels of fluoride such that the final concentration is 0.7 parts per million (ppm) in finished water at both Fleur Drive and L.D. McMullen Treatment Plants. Natural levels of fluoride in DMWW’s source water range from 0.2 to 0.5 ppm.

This adjustment is in accordance to recent recommendations by the U.S. Department of Health & Human Services (HHS), Environmental Protection Agency (EPA), American Dental Association, American Water Works Association and Iowa Department of Public Health.

According to HHS and EPA, the adjustment will maximize the health benefits of water fluoridation, an important tool in the prevention of tooth decay while reducing the possibility of children receiving too much fluoride.

“The 0.7 ppm adjustment continues to promote the importance of community water fluoridation as a means to decrease dental decay while accounting for the presence of other fluoride containing products and exposure,” says Randy Beavers, CEO and General Manger, Des Moines Water Works.  “The Centers for Disease Control and Prevention continues to name fluoridation of drinking water one of the ten great public health achievements of the 20th century.”

This adjustment reflects DMWW’s continued support of national and state health policy for the benefit of water fluoridation and reassures customers that adjustments in practices will occur periodically as new scientific evidence becomes available.

    If the natural fluoride levels are near .5 ppm, than why should we be paying to add any amount at all? I don’t support the science behind claiming that added fluoride decreases tooth decay, and there is much evidence suggesting it promotes it.

    Do I, as a taxpayer, pay through taxes for this added fluoridation? If so, I do not like it one bit.

    I agree with Chris, and urge DMWW to return to “natural levels” of fluoride If in the future, DMWW relies on well water which contains below natural level of fluoride, I’d like to reopen this debate to see if any should be added.

    OR – WIC program currently provides mothers with powdered formula, but does not provide distilled/purified water — I’d like to see this changed, to encourage new mothers NOT to use tap water when mixing formula until the child is at least one year of age.

    Older neighborhoods have a double whammy against developing young brains…they have lead in their paint (and even some water pipes/soldering) plus added fluoride – we have to correct this as much as possible…and I am for limiting the fluoride to infants.
