Fluoridation is the process of adding fluorine compounds to the drinking water. Fluoridated water can help decrease tooth decay in the population. A concentration of 1 ppm of fluorine is typically required to provide adequate amounts. While daily water consumption per person is 151.0 gallons, most people only consume 7.6 of this water; the rest is used for cleaning or gardening. What percent of the sodium fluoride is “wasted”?
