A little less fluoride in the water
January 12, 2011

The Des Moines Water Works has backed off the amount of fluoride it adds to the municipal drinking water, dropping from 1.0 parts per million (ppm) to 0.7 ppm on the advice of new recommendations from the US Department of Health and Human Services and the EPA. The new recommendations reflect the fact that drinking water is now one of several sources of fluoride for most people -- a change from when fluoridation was first introduced, in the 1940s. Toothpaste now, for instance, routinely includes fluoride -- whereas it did not when water was first fluoridated.

The revisions to the standard simply reflect a natural evolution in the process of fluoridation, reflecting a refinement of the scientific standards rather than a rejection of the science (which is how some people might hope to interpret them). Fluoridation is one of the landmark achievements in public health over the last century.
