Bottled water is highly regulated as a packaged food product by the U.S. Food and Drug Administration (FDA) and subject to FDA’s extensive food safety, labeling and inspection requirements. By law, the FDA Standard of Quality for bottled water requires that regulations for bottled water are at least as stringent and protective of public health, according to the International Bottled Water Organization.

American Waterworks Director Jack Hoffbauer says that “over 90 percent of the water utilities in this country comply with the EPA regulations and there’s no tougher regulations in the world.”
