NRC 2006 Review: Fluorides in Drinking Water

NRC (National Research Council) 2006 Fluoride in Drinking Water: A Scientific Review of EPA's Standards. Washington, DC. National Academies Press. [Available to read free online at:]

Relevance of the NRC Review to Artificial Water Fluoridation

The NRC report did an extremely thorough review of fluoride intake, by age group, considering all sources of fluoride intake (water, dentifrices, food, air, soil, pesticides, pharmaceuticals), including artificially fluoridated drinking water. In addition, the committee looked at population subgroups of special concern such as those with high water consumption, and those with impaired fluoride excretion (see:Social Justice Equals Protecting the Vulnerable). A number of the toxicity studies that the committee reviewed involved fluoridated water or exposures equivalent to those expected with artificially fluoridated water.

The committee reported that fluoride exposure is plausibly associated with a number of health effects, including neurotoxicity, gastrointestinal problems, carcinogenicity, endocrine problems, dental fluorosis, and skeletal fluorosis with its associated incidence of bone fractures and arthritic-like symptoms. (see: National Research Council 2006: Summary of Health Effects)

The ranges of intake levels, or estimated average intake levels, associated with a number of adverse effects, are in the range of intakes expected with artificially fluoridated drinking water. (see: Chapter 2, Table 2-4 Appendix B, Table B-11, Table B-12, Table B-13, Table B-14, Table B-17)

Scientific Fraud

The Scientific Method underpinning research presupposes a willingness to continually reexamine scientific evidence and assumptions. Science is not a collection of facts but a process of weeding out misinformation and testing preliminary results with care and diligence. Scientific discourse attempts to refute what has been found, not to gather supporting evidence for the status quo.

There is currently no means for holding scientists accountable for things they may say in the public forum by either self-regulation or government legislation. Therefore, any individual(s) who distort(s) or misrepresent(s) scientific evidence and known facts for reasons of ignorance, political expedience, financial gain, or self-interest imperil(s) the integrity of scientific discourse and leads to an erosion of public trust in our government institutions where policy decisions regarding public health are deemed to be made, based on scientific evidence.

Health Canada committee members involved in this review knew, or should have known, what the actual findings of the NRC committee were. Misrepresentation of this review is problematic because:

  • it casts doubt on the competence of those involved in this review;

  • damages the credibility of our national regulatory body;

  • this mis-information is repeated by government agencies, individuals and organizations.

Health Canada Misrepresents National Research Council Review 2006

The Health Canada 2009 draft review incorrectly claims the following:
"The [NRC] Committee restricted its attention to studies that examined long-term exposure to fluoride in the range of 24 mg/L or above in drinking water."

Two of the NRC 2006 committee members reply:

"Our charge was to evaluate the EPA permissible levels for fluoride in drinking water which are 2 ppm and 4 ppm and we focused on those levels but our report contains considerable information on lower levels of fluoride."

Doull (Chair of the National Academy of Science 2006 committee). Email: 20/3/2010.

"Health Canada gives an inaccurate characterization of the National Research Council's work."
Source: Dr. Kathleen Thiessen (Member of the National Academy of Science 2006 committee)

"The NRC (2006a) did not restrict its attention to studies of fluoride in the range of 2-4 mg/L or above in drinking water. Many of the cancer studies and Down syndrome studies involved "fluoridated" water (0.7-1.2 mg/L). Many of the endocrine studies involved exposure ranges comparable to those expected for populations on fluoridated water. The discussions of exposure and of pharmacokinetics involved the whole exposure range, including fluoridated water."

Fluoride Works Topically Why Swallow?

We should not drink sunscreen or fluoride because...

  • they are toxic to swallow

  • they do not work by swallowing

"Its actions primarily are topical for both adults and children." Source: US Centers for Disease Control 1999


Fetuses and Infants are more vulnerable to fluoride toxicity because:

  • The blood-brain barrier is not fully formed

  • The kidneys are not fully developed

  • They ingest more fluoride per body weight than adults (Children are given child-sized asprin)

  • Fluoride accumulates in body for entire life

Readers' Comments

I would like to know if a legal challenge against the city can by mounted. I am a Registered Nurse and only recently, during the city debates, became educated about the dangers of ingesting toxic fluoride.
