Opponents of a plan to add fluoride to the water supply in Portland filed petitions that could put the issue to a vote. The plan was passed by the City Council last month, set to take effect in 2014, but foes said the idea was rushed and that concerns about fluoride in dental decay prevention are unresolved. A group collecting petitions, Clean Water Portland, said that more than 41,000 signatures were submitted, more than twice the number needed to put the matter on the ballot.
