Interview with EPA’s Dr. William Marcus on NTP’s Fluoride/Cancer Study
The following is an interview with Dr. William Marcus, Senior Science Advisor in EPA’s Office of Drinking Water, concerning the National Toxicology Program’s animal study on fluoride & cancer.
Fluoride & Liver Cancers in NTP Bioassay
On October 28, 1988, Battelle Columbus Laboratories submitted its Final Report to the NTP concerning the results of the Mouse study. The principal finding of Battelle’s report was that a dose-dependent increase of a rare liver cancer (hepatocholangiocarcinoma) had occurred in the fluoride-treated male and female mice.
Interview with EPA’s Dr. William Hirzy About Fluoride & Cancer
The following is an excerpt of Michael Connett’s interview with Dr. J. William Hirzy, Senior Vice President of EPA’s Headquarters Union in Washington DC. The interview took place on July 3, 2000, a couple days after Hirzy testified before the US Senate calling for an independent review of the tumor slides from the National Toxicology Program’s bioassay for fluoride.

Scientist Who Spoke Out on Fluoride Ordered Reinstated to Job
A two-year battle against the federal government ended in victory for a scientist fired from the Environmental Protection Agency after raising health concerns about fluoride. Labor Secretary Robert B. Reich ordered that William L. Marcus be returned to his $ 87,000-a-year job at EPA and be paid back wages, legal costs and a $ 50,000 penalty.
Reich Orders EPA to Reinstate Scientist
In a precedent-setting ruling, U.S. Department of Labor (DOL) Secretary Robert B. Reich has ordered the U.S. Environmental Protection Agency (EPA) to reinstate toxicologist Dr. William L. Marcus.
EPA Ordered to Reinstate Whistleblower
The Environmental Protection Agency has been ordered to reinstate a senior scientist and pay him $ 50,000 for emotional distress after he was fired allegedly for whistleblowing activities. The Administrative Law Judge concluded that EPA’s reason for the firing were “a pretext” and that Marcus really was dismissed “because he publicly questioned and opposed EPA’s fluoride policy.”
The Lancet: More About Fluoride
William L. Marcus, chief toxicologist for the Environmental Protection Agency’s drinking water programme, claimed that the original findings of the NTP study showed the cancer hazard from fluoridated drinking water to be greater than the NTP was telling the public.
Fluoride bioassay study under scrutiny
A recent animal study by the National Toxicology Program that failed to give fluoride a totally clean bill of health is now being questioned as being maybe too lenient on the widely used tooth decay preventative. Also, a government panel appointed to assess the risks and benefits of human exposure to fluoride and to put the NTP study into broader perspective is apparently running into some problems and has delayed its final report.
The Risks of Fluoride: The Long Awaited Verdict
If it were any other chemical, the news that fluoride may cause cancer would probably have been greeted with little more than mutters about the latest cancer causing substances of the week. But fluoride is no ordinary chemical.
ACSH Considers Legal Action Against Attempts to Reclassify Fluoride
The American Council on Science and Health said last week that it will seek to restrain any federal agency from banning or seeking to reclassify fluoride from a non-carcinogen to a probable carcinogen.
