The Metropolitan Water District of Southern California on Monday will start pumping fluoride into Orange County’s water supply.
MWD Spokesman Bob Muir said the fluoride injection system at the Robert B. Diemer Filtration plant in Yorba Linda is ready. Diemer supplies about half of the drinking water in Orange County.
Fountain Valley and Huntington Beach have been the only communities in the county with fluoridated water.
The Diemer plant is the second-to-last MWD plant to go online with the chemical, advocated by dentists and doctors who say it promotes healthy teeth.
Muir acknowledged the concerns of some national groups and community members who say fluoride is actually harmful to health, but he pointed out that it was a consortium of dentists and medical doctors who approached the MWD board and asked it to fluoridate Southern California’s water supply in the first place.
“There are pockets of the community that have questions and concerns about fluoridation,” he said. “This is being done at the request of dentists and doctors throughout the region.”
Muir says he often has to deal with angry customers complaining about fluoridation. Many county residents, however, aren’t worried.
“I would assume if it’s being done, it’s being done to improve the quality of our teeth,” said Joe Carey, 46, of Rancho Santa Margarita. “If it ultimately does that, I don’t have a problem with it.”
“I’m definitely for it,” said Bill Mitchell, 83, of Placentia. “I think it’s a great preventative and I don’t have any problem with it.”
