On June 29th, 2000, Dr. William Hirzy was invited to give testimony to the U.S. Senate Committee on Environment and Public Works, Subcommittee on Fisheries, Wildlife, and Water on behalf of the National Treasury Employees Union (NTEU) Chapter 280 – U.S. Environmental Protection Agency, National Headquarters.

At the time, Dr. Hirzy was serving his sixth term as the Senior Vice-President of the Union. His presentation that day was, “Why EPA’s Union of Professionals Opposes Fluoridation.” This is a video that documents the presentation along with interviews with Dr. Hirzy where he describes the reasoning behind the professional and official stance of his Union members in direct opposition to the EPA’s administrative support of fluoridation.
