Water Fluoridation

Improving Dental Health


The City fluoridates our drinking water to improve the dental health for consumers of Beaverton’s water. The fluoridation system was completed, tested, and began service in mid-May 2004. Since then, the City’s water has been fluoridated at a target level of 0.9 parts per million (ppm). In January 2011 the U.S. Department of Health and Human Services (HHS) and the U.S. Environmental Protection Agency’s (EPA) issued a press release that recommended lowering the fluoride level in drinking water. Based on these recommendations, the City reduced the target fluoride level from 0.9 ppm to 0.7 ppm (parts per million).

Sodium fluoride is added to Beaverton’s drinking water after it leaves the Joint Water Commission (JWC) Water Treatment Plant and before entering the City for distribution. The City’s fluoride feed facility employs sensitive instruments to measure and maintain the desired level of fluoride in the drinking water system. In addition, seven online electronic fluoride analyzers are situated in different locations throughout the City to monitor fluoride levels in the drinking water 24 hours a day.
