Voters in Amesbury, MA, have turned down the option to resume fluoridating the town's water supply.
The town had been adding sodium fluoride to its water since 1967, but stopped in 2009, citing concerns that 40% of the material from new Chinese suppliers was not dissolving, according to a story in the Newburyport News.
The town's water system is being retrofitted to avoid clogs, and officials have sought a more reliable supplier of the chemical.
Local health officials had recommended that fluoridation be resumed, but opponents said it was unnecessary.
