When the City of Green Bay began fluoridation of its drinking water: The Green Bay Water Utility began adding fluoride to water in 1957 when the Green Bay City Council passed a resolution directing its use based on a request from the Green Bay Health Department.

How much fluoride we put in the water: The current recommended level from the U.S. Department of Health and Human Services for public water supplies is 0.7 mg/l. The Utility adds fluoride at a dose of 0.7 mg/l to conform with current health recommendations set forth by the Environmental Protection Agency (EPA), taking into account information from the Centers for Disease Control, and other respected national and international health organizations.

Why do we fluoridate? Fluoride, in low levels in drinking water, is proven to help prevent tooth decay. The American Dental Association (ADA), The American Medical Association (AMA) and the U.S. Public Health Service and Centers for Disease Control (CDC) have endorsed water fluoridation. The CDC has even counted water fluoridation one of the top 10 public health achievements of the 20th century. These entities have evaluated – and continue to evaluate – worldwide, peer-reviewed, clinical studies and evidence-based science regarding fluoridation. They have determined the fluoridation of public water is safe and effective at the level noted above.
