PORTLAND — Residents are voting to keep Portland as the largest U.S. city without fluoride in the water or any plans to add it.
With more than half the expected ballots counted, the Multnomah County election website shows the fluoride proposal failing, 60 percent to 40 percent.
Voters in Portland twice rejected fluoridation before approving it in 1978. That plan was overturned two years later, before any fluoride was ever added to the water.
The City Council voted last year to add fluoride to the water supply that serves about 900,000 people. But opponents quickly gathered enough signatures to force a vote on the subject.
