Drinking Water Fluoridation
The City’s fluoridation station 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). Sodium fluoride is added to Beaverton’s drinking water after it leaves the JWC water treatment plant and before entering the City for distribution. The City’s fluoride feed facility is equipped to ensure that the desired level of fluoride is maintained in the drinking water supply. In addition, four on-line electronic fluoride analyzers are installed at different locations throughout the City to monitor fluoride levels in the drinking water 24 hours a day. The purpose of fluoridating the City’s drinking water is to improve the dental health of consumers of Beaverton’s water.
Fluoridation Monitoring and Operation
The City’s fluoride feed facility is equipped to
ensure that the desired level of fluoride is maintained
in the drinking water supply. On-line electronic
fluoride analyzers installed in different locations around
the City will monitor fluoride levels in the drinking
water 24-hours a day. Data collected from the fluoride
analyzers is displayed and stored on a water
system master control computer. The master control
computer uses the data to control and adjust the
level of fluoride, as programmed by City water
maintenance staff. City water maintenance staff
are required by the Oregon Department of Human
Services to have water treatment certification, which
covers fluoridation. The Oregon Department of
Human Services also requires regular additional
hand-collected drinking water samples to be tested
by a state certified laboratory to check calibration of
the on-line electronic monitoring analyzers. A wide
range of water quality data is reported by the City
of Beaverton to the Oregon Department of Human Services. Beaverton’s test results and water system
information can be found on the Oregon Department of Human Services Internet web site at:

Fluoridated Water in the Tigard Water District
Though none of Tigard’s wholesale water providers fluoridate their water supplies, water from the Joint Water Commission is piped through the City of Beaverton’s water distribution system. Since Beaverton adds fluoride to the water supply, water delivered via this route does contain fluoride. Only those water customers nearest to the water source entry point, in the vicinity of Barrows Road and Scholls Ferry Road, will receive fluoridated water.
To find out more, please contact the City of Tigard’s Water Quality Program Coordinator, Sally Mills at 503-718-2604 or sally@tigard-or.gov.
