 fluoridation of public water supplies---congressional hearing

STATEMENT OF Dr. J. WILLIAM HIRZY
NATIONAL TREASURY EMPLOYEES UNION CHAPTER 280
BEFORE THE SUBCOMMITTEE ON WILDLIFE, FISHERIES AND DRINKING WATER
UNITED STATES SENATE
JUNE 29, 2000

Good morning Mr. Chairman and Members of the Subcommittee. I appreciate the
opportunity to appear before this Subcommittee to present the views of the
union, of which I am a Vice-President, on the subject of fluoridation of
public water supplies.

Our union is comprised of and represents the professional employees at the
headquarters location of the U.S. Environmental Protection Agency in
Washington D.C. Our members include toxicologists, biologists, chemists,
engineers, lawyers and others defined by law as "professionals." The work we
do includes evaluation of toxicity, exposure and economic information for
management's use in formulating public health and environmental protection
policy. I am not here as a representative of EPA, but rather as a
representative of EPA headquarters professional employees, through their duly
elected labor union. The union first got involved in this issue in 1985 as a
matter of professional ethics. In 1997 we most recently voted to oppose
fluoridation. Our opposition has strengthened since then.

Summary of Recommendations

1) We ask that you order an independent review of a cancer bioassay
previously mandated by Congressional committee and subsequently performed by
Battelle Memorial Institute with appropriate blinding and instructions that
all reviewer's independent determinations be reported to this Committee.

2) We ask that you order that the two waste products of the fertilizer
industry that are now used in 90% of fluoridation programs, for which EPA
states they are not able to identify any chronic studies, be used in any
future toxicity studies, rather than a substitute chemical. Further, since
federal agencies are actively advocating that each man woman and child drink,
eat and bathe in these chemicals, silicofluorides should be placed at the
head of the list for establishing a MCL that complies with the Safe Drinking
Water Act. This means that the MCL be protective of the most sensitive of our
population, including infants, with an appropriate margin of safety for
ingestion over an entire lifetime.

3) We ask that you order an epidemiology study comparing children with dental
fluorosis to those not displaying overdose during growth and development
years for behavioral and other disorders.

4) We ask that you convene a joint Congressional Committee to give the only
substance that is being mandated for ingestion throughout this country the
full hearing that it deserves.

National Review of Fluoridation The Subcommittee's hearing today can only
begin to get at the issues surrounding the policy of water fluoridation in
the United States, a massive experiment that has been run on the American
public, without informed consent, for over fifty years. The last
Congressional hearings on this subject were held in 1977. Much knowledge has
been gained in the intervening years. It is high time for a national review
of this policy by a Joint Select Committee of Congress. New hearings should
explore, at minimum, these points:

1) excessive and un-controlled fluoride exposures; 2) altered findings of a
cancer bioassay; 3) the results and implications of recent brain effects
research; 4) the "protected pollutant" status of fluoride within EPA; 5) the
altered recommendations to EPA of a 1983 Surgeon General's Panel on fluoride;
6) the results of a fifty-year experiment on fluoridation in two New York
communities; 7) the findings of fact in three landmark lawsuits since 1978;
8) the findings and implications of recent research linking the predominant
fluoridation chemical with elevated blood-lead levels in children and
anti-social behavior; and 9) changing views among dental researchers on the
efficacy of water fluoridation

Fluoride Exposures Are Excessive and Un-controlled According to a study by
the National Institute of Dental Research, 66 percent of America's children
in fluoridated communities show the visible sign of over-exposure and
fluoride toxicity, dental fluorosis (1). That result is from a survey done in
the mid-1980's and the figure today is undoubtedly much higher.

Centers for Disease Control and EPA claim that dental fluorosis is only a
"cosmetic" effect. God did not create humans with fluorosed teeth. That
effect occurs when children ingest more fluoride than their bodies can handle
with the metabolic processes we were born with, and their teeth are damaged
as a result. And not only their teeth. Children's bones and other tissues, as
well as their developing teeth are accumulating too much fluoride. We can see
the effect on teeth. Few researchers, if any, are looking for the effects of
excessive fluoride exposure on bone and other tissues in American children.
What has been reported so far in this connection is disturbing. One example
is epidemiological evidence (2a, 2b) showing elevated bone cancer in young
men related to consumption of fluoridated drinking water.

Without trying to ascribe a cause and effect relationship beforehand, we do
know that American children in large numbers are afflicted with
hyperactivity-attention deficit disorder, that autism seems to be on the
rise, that bone fractures in young athletes and military personnel are on the
rise, that earlier onset of puberty in young women is occurring. There are
biologically plausible mechanisms described in peer-reviewed research on
fluoride that can link some of these effects to fluoride exposures (e.g.
3,4,5,6). Considering the economic and human costs of these conditions, we
believe that Congress should order epidemiology studies that use dental
fluorosis as an index of exposure to determine if there are links between
such effects and fluoride over-exposure.

In the interim, while this epidemiology is conducted, we believe that a
national moratorium on water fluoridation should be instituted. There will be
a hue and cry from some quarters, predicting increased dental caries, but
Europe has about the same rate of dental caries as the U.S. (7) and most
European countries do not fluoridate (8). I am submitting letters from
European and Asian authorities on this point. There are studies in the U.S.
of localities that have interrupted fluoridation with no discernable increase
in dental caries rates (e.g., 9). And people who want the freedom of choice
to continue to ingest fluoride can do so by other means.

Cancer Bioassay Findings In 1990, the results of the National Toxicology
Program cancer bioassay on sodium fluoride were published (10), the initial
findings of which would have ended fluoridation. But a special commission was
hastily convened to review the findings, resulting in the salvation of
fluoridation through systematic down-grading of the evidence of
carcinogenicity. The final, published version of the NTP report says that
there is, "equivocal evidence of carcinogenicity in male rats," changed from
"clear evidence of carcinogenicity in male rats."

The change prompted Dr. William Marcus, who was then Senior Science Adviser
and Toxicologist in the Office of Drinking Water, to blow the whistle about
the issue (22), which led to his firing by EPA. Dr. Marcus sued EPA, won his
case and was reinstated with back pay, benefits and compensatory damages. I
am submitting material from Dr. Marcus to the Subcommittee dealing with the
cancer and neurotoxicity risks posed by fluoridation.

We believe the Subcommittee should call for an independent review of the
tumor slides from the bioassay, as was called for by Dr. Marcus (22), with
the results to be presented in a hearing before a Select Committee of the
Congress. The scientists who conducted the original study, the original
reviewers of the study, and the "review commission" members should be called,
and an explanation given for the changed findings.

Brain Effects Research Since 1994 there have been six publications that link
fluoride exposure to direct adverse effects on the brain. Two epidemiology
studies from China indicate depression of I.Q. in children (11,12). Another
paper (3) shows a link between prenatal exposure of animals to fluoride and
subsequent birth of off-spring which are hyperactive throughout life. A 1998
paper shows brain and kidney damage in animals given the "optimal" dosage of
fluoride, viz. one part per million (13). And another (14) shows decreased
levels of a key substance in the brain that may explain the results in the
other paper from that journal. Another publication (5) links fluoride dosing
to adverse effects on the brain's pineal gland and pre-mature onset of sexual
maturity in animals. Earlier onset of menstruation of girls in fluoridated
Newburg, New York has also been reported (6).

Given the national concern over incidence of attention deficit-hyperactivity
disorder and autism in our children, we believe that the authors of these
studies should be called before a Select Committee, along with those who have
critiqued their studies, so the American public and the Congress can
understand the implications of this work.

Fluoride as a Protected Pollutant The classic example of EPA's protective
treatment of this substance, recognized the world over and in the U.S. before
the linguistic de-toxification campaign of the 1940's and 1950's as a major
environmental pollutant, is the 1983 statement by EPA's then Deputy Assistant
Administrator for Water, Rebecca Hanmer (15), that EPA views the use of
hydrofluosilicic acid recovered from the waste stream of phosphate fertilizer
manufacture as,

"...an ideal solution to a long standing problem. By recovering by-product
fluosilicic acid (sic) from fertilizer manufacturing, water and air pollution
are minimized, and water authorities have a low-cost source of fluoride..."

In other words, the solution to pollution is dilution, as long as the
pollutant is dumped straight into drinking water systems and not into rivers
or the atmosphere. I am submitting a copy of her letter.

Other Federal entities are also protective of fluoride. Congressman Calvert
of the House Science Committee has sent letters of inquiry to EPA and other
Federal entities on the matter of fluoride, answers to which have not yet
been received.

We believe that EPA and other Federal officials should be called to testify
on the manner in which fluoride has been protected. The union will be happy
to assist the Congress in identifying targets for an inquiry. For instance,
hydrofluosilicic acid does not appear on the Toxic Release Inventory list of
chemicals, and there is a remarkable discrepancy among the Maximum
Contaminant Levels for fluoride, arsenic and lead, given the relative
toxicities of these substances. Surgeon General's Panel on Fluoride We
believe that EPA staff and managers should be called to testify, along with
members of the 1983 Surgeon General's panel and officials of the Department
of Human Services, to explain how the original recommendations of the Surgeon
General's panel (16) were altered to allow EPA to set otherwise unjustifiable
drinking water standards for fluoride.

Kingston and Newburg, New York Results In 1998, the results of a fifty-year
fluoridation experiment involving Kingston, New York (un-fluoridated) and
Newburg, New York (fluoridated) were published (17). In summary, there is no
overall significant difference in rates of dental decay in children in the
two cities, but children in the fluoridated city show significantly higher
rates of dental fluorosis than children in the un-fluoridated city.

We believe that the authors of this study and representatives of the Centers
For Disease Control and EPA should be called before a Select Committee to
explain the increase in dental fluorosis among American children and the
implications of that increase for skeletal and other effects as the children
mature, including bone cancer, stress fractures and arthritis.

Findings of Fact by Judges In three landmark cases adjudicated since 1978 in
Pennsylvania, Illinois and Texas (18), judges with no interest except finding
fact and administering justice heard prolonged testimony from proponents and
opponents of fluoridation and made dispassionate findings of fact. I cite one
such instance here.

In November, 1978, Judge John Flaherty, now Chief Justice of the Supreme
Court of Pennsylvania, issued findings in the case, Aitkenhead v. Borough of
West View, tried before him in the Allegheny Court of Common Pleas. Testimony
in the case filled 2800 transcript pages and fully elucidated the benefits
and risks of water fluoridation as understood in 1978. Judge Flaherty issued
an injunction against fluoridation in the case, but the injunction was
overturned on jurisdictional grounds. His findings of fact were not disturbed
by appellate action. Judge Flaherty, in a July, 1979 letter to the Mayor of
Aukland New Zealand wrote the following about the case:

"In my view, the evidence is quite convincing that the addition of sodium
fluoride to the public water supply at one part per million is extremely
deleterious to the human body, and, a review of the evidence will disclose
that there was no convincing evidence to the contrary...

"Prior to hearing this case, I gave the matter of fluoridation little, if
any, thought, but I received quite an education, and noted that the
proponents of fluoridation do nothing more than try to impune (sic) the
objectivity of those who oppose fluoridation."

In the Illinois decision, Judge Ronald Niemann concludes: "This record is
barren of any credible and reputable scientific epidemiological studies and
or analysis of statistical data which would support the Illinois
Legislature's determination that fluoridation of the water supplies is both a
safe and effective means of promoting public health."

Judge Anthony Farris in Texas found: "[That] the artificial fluoridation of
public water supplies, such as contemplated by {Houston} City ordinance No.
80-2530 may cause or contribute to the cause of cancer, genetic damage,
intolerant reactions, and chronic toxicity, including dental mottling, in
man; that the said artificial fluoridation may aggravate malnutrition and
existing illness in man; and that the value of said artificial fluoridation
is in some doubt as to reduction of tooth decay in man."
 

The significance of Judge Flaherty's statement and his and the other two
judges' findings of fact is this: proponents of fluoridation are fond of
reciting endorsement statements by authorities, such as those by CDC and the
American Dental Association, both of which have long-standing commitments
that are hard if not impossible to recant, on the safety and efficacy of
fluoridation. Now come three truly independent servants of justice, the
judges in these three cases, and they find that fluoridation of water
supplies is not justified.

Proponents of fluoridation are absolutely right about one thing: there is no
real controversy about fluoridation when the facts are heard by an open mind.

I am submitting a copy of the excerpted letter from Judge Flaherty and
another letter referenced in it that was sent to Judge Flaherty by Dr. Peter
Sammartino, then Chancellor of Fairleigh Dickenson University. I am also
submitting a reprint copy of an article in the Spring 1999 issue of the
Florida State University Journal of Land Use and Environmental Law by Jack
Graham and Dr. Pierre Morin, titled "Highlights in North American Litigation
During the Twentieth Century on Artificial Fluoridation of Public Water. Mr.
Graham was chief litigator in the case before Judge Flaherty and in the other
two cases (in Illinois and Texas).

We believe that Mr. Graham should be called before a Select Committee along
with, if appropriate, the judges in these three cases who could relate their
experience as trial judges in these cases.

Hydrofluosilicic Acid There are no chronic toxicity data on the predominant
chemical, hydrofluosilicic acid and its sodium salt, used to fluoridate
American communities. Newly published studies (19) indicate a link between
use of these chemicals and elevated level of lead in children's blood and
anti-social behavior. Material from the authors of these studies has been
submitted by them independently.
 

We believe the authors of these papers and their critics should be called
before a Select Committee to explain to you and the American people what
these papers mean for continuation of the policy of fluoridation.

Changing Views on Efficacy and Risk In recent years, two prominent dental
researchers who were leaders of the pro-fluoridation movement announced
reversals of their former positions because they concluded that water
fluoridation is not an effective means of reducing dental caries and that it
poses serious risks to human health. The late Dr. John Colquhoun was
Principal Dental Officer of Aukland, New Zealand, and he published his
reasons for changing sides in 1997 (20). In 1999, Dr. Hardy Limeback, Head of
Preventive Dentistry, University of Toronto, announced his change of views,
then published a statement (21) dated April 2000. I am submitting a copy of
Dr. Limeback's publications.

We believe that Dr. Limeback, along with fluoridation proponents who have not
changed their minds, such as Drs. Ernest Newbrun and Herschel Horowitz,
should be called before a Select Committee to testify on the reasons for
their respective positions.

Thank you for you consideration, and I will be happy to take questions.
