Fluoride in Drinking Water: A Scientific Review of EPA's Standards

The publication in 2006 of a 500-page review of fluoride’s toxicology by a distinguished panel appointed by the National Research Council of the National Academies (NRC, 2006). The NRC report concluded that the US Environmental Protection Agency’s (EPA) safe drinking water standard for fluoride (i.e. maximum contaminant level goal or MCLG) of 4 parts per million (ppm) is unsafe and should be lowered. Despite over 60 years of fluoridation, the report listed many basic research questions that have not been addressed. Still, the panel reviewed a large body of literature in which fluoride has a statistically significant association with a wide range of adverse effects. These include an increased risk of bone fractures, decreased thyroid function, lowered IQ, arthritic-like conditions, dental fluorosis and, possibly, osteosarcoma.Click Here to read a PDF version of this document.

Over 3,000 Professionals Call for an End to Fluoridation of Drinking Water

The over 3,000 signers represent a remarkable coming together of those concerned about fluoride and those concerned about mercury issues; doctors practicing conventional medicine and those pursuing alternative treatments and the public health and the environmental health communities. All believe that public health policy should be determined honestly with full attention paid to sound science and to ethical principles.

According to Dr. Paul Connett, the Executive Director of FAN, “What we are seeing here is the judgment of professionals across the world, not trapped by a ‘fluoridation belief system,’ that the information on the health effects contained in the National Research Council report of 2006, together with a growing number of peer reviewed studies showing that fluoridation has only weak or no benefits, leads to one conclusion: the meager benefits do not outweigh the serious risks and fluoridation must be stopped.”

Connett adds, “Now our task is to get health officials, regulators, and the media to exercise due diligence in this matter and seriously examine the information presented in the Professionals’ Statement. Fluoridation will only end in the US when officials in the Oral Health Division of the CDC are forced to defend, under oath, their zealous promotion of this practice. They appear to be oblivious to its ineffectiveness and the dangers it poses to the American people – and people in the handful of other fluoridated countries.”


The following documents why our union, formerly National Federation of Federal Employees Local 2050 and since April 1998 Chapter 280 of the National Treasury Employees Union, took the stand it did opposing fluoridation of drinking water supplies. Our union is comprised of and represents the approximately 1500 scientists, lawyers, engineers and other professional employees at EPA Headquarters here in Washington, D.C.

Since then our opposition to drinking water fluoridation has grown, based on the scientific literature documenting the increasingly out-of-control exposures to fluoride, the lack of benefit to dental health from ingestion of fluoride and the hazards to human health from such ingestion. These hazards include acute toxic hazard, such as to people with impaired kidney function, as well as chronic toxic hazards of gene mutations, cancer, reproductive effects, neurotoxicity, bone pathology and dental fluorosis. First, a review of recent neurotoxicity research results.

Second Thoughts About Fluoride (Excerpts)

The Scientific American study "Concluded that fluoride can subtly alter endocrine function, especially in the thyroid -- the gland that produces hormones regulating growth and metabolism."

Fluoride's Impact On The Brain

“It is hard to believe that any "weight of evidence" analysis could possibly dismiss fluoride's neurological impacts. There have now been over 40 animal studies which show that fluoride can damage the brain, and no less than 18 studies which show that fluoride lowers IQ in children, and only 2 that don't. I look forward to reading the full report when it is made available,” says Paul Connett, PhD, FAN Executive Director.

Warning: This Daily Habit is Damaging Your Bones, Brain, Kidneys, and Thyroid

In the case of water fluoridation, the chemicals used to fluoridate the water that more than 180 million people drink each day are not pharmaceutical grade, but rather hazardous waste products of the phosphate fertilizer industry; it is illegal to dump these into rivers and lakes or release the parent gases into the atmosphere.

In addition, water fluoridation is a prime example of one of the worst medical practices possible—forced medication with no control over the dose or who gets it. Perhaps most shocking of all, it is not subject to any federal regulation
