From the Division of Oral Health, Centers for Disease Control and Prevention

The adjustment of fluoride in drinking water to levels optimum for oral health was first implemented in Grand Rapids, Michigan, in 1945. The first surveys on water fluoridation status in the United States were compiled in 1952 by the American Dental Association Council on Dental Health and the American Water Works Association. The surveys identified which communities were implementing this emerging technology.

The U.S. Public Health Service has reported water fluoridation statistics periodically since 1956. The Water Fluoridation Census (Census) was published periodically from 1963 through 1992, reporting data compiled from the EPA, U.S. Census Bureau, and surveys of state drinking water and oral health programs. The CDC has been the lead agency in this effort since 1975, and an objective for water fluoridation has been included among the Healthy People national objectives since 1979.

  1. The 2000, 2002, 2004, and 2006 national and state statistics pages were abstracted from the report: Populations receiving optimally fluoridated public drinking water – United States, 1992–2006. MMWR 2008; 57(27):737–741.
  2. This publication provided a summary of identified naturally fluoridated water systems, but was not a fluoridation census of the United States.
  3. This article is the earliest known published listing of fluoridated systems. An earlier listing by the American Water Works Association was not as complete as this listing.
