As with some other countries, water fluoridation in the United States is a contentious issue. As of May 2000, 42 of the 50 largest U.S. cities had water fluoridation. On January 25, 1945, Grand Rapids, Michigan, became the first community in the United States to fluoridate its drinking water to prevent tooth decay. U.S. regulations for bottled water do not require disclosing fluoride content. A survey of bottled water in Cleveland and in Iowa, published in 2000, found that most had fluoride levels well below the 1 mg/L level common in tap waters.
