Is fluoridation considered wasteful because a small proportion of the water goes for human consumption?
Water that is treated with chlorine, softening chemicals, and fluorides is used for purposes other than drinking, such as for watering lawns, washing cars, and industry. More than 38 different chemicals are used to treat water. It is more practical, though, to have the entire water system treated than to attempt to treat the drinking water alone. Fluoridation of public water supplies is not a waste. It is the most practical method to reduce dental caries and is endorsed by the American Water Works Association (American Water Works Association, 1982).
