There is an overwhelming consensus amongst dental,
medical and public health professionals supporting
for the effectiveness of water fluoridation is incontrovertible. More than a
dozen large-scale literature reviews have found water fluoridation,
confers a considerable Dental Caries preventive benefit in
children. Further to this, water fluoridation and its effect on the
tooth structure provides a benefit to adults across their lifespan.

Tooth decay, or caries, is caused by bacteria that thrive
on sugars in the mouth and produce acids. Left in contact with a tooth, the
acids draw out minerals, creating microscopic pores. Decay progresses
slowly, and it may take years for a full-blown hole, or cavity, to form;
until that point, it can still be reversed. Mineral-containing saliva is
constantly working to replenish the teeth, and fluoride aids

rulemaking to protect adequately against such risk .
B. What is EPA’s Reason for this Response?
For the purpose of making its decision, EPA evaluated the information
presented or referenced in the petition as well
as the Agency’s authority and requirements under TSCA sections 6, 9, and 21.
After careful consideration, EPA denied the TSCA section 21 petition because
the evidence presented by the petitioners
does not adequately support a conclusion that HFSA, when used as a fluoridation agent, presents or will present an
unreasonable risk to health or the environment and that a TSCA section 6
rulemaking is necessary to protect adequately
against such risk . More specifically:
EPA evaluated the cost-benefit analysis submitted by the petitioners and
determined that the petitioners miscalculated
net benefits for pharmaceutical grade NaF
compared to HFSA.
Specifically, it appears that the petitioners failed to convert their
estimates of lifetime cancer risk to estimates
of annual cancer risk for the purpose of calculating annual net benefits.
This error alone results in a 70-fold
overestimation of the number of annual cancer cases due to arsenic.
That is, for the analysis in which the petitioners evaluate arsenic
concentrations of 0.078 parts per billion (ppb)
due to HFSA and 0.00084 ppb due to pharmaceutical grade NaF, the estimated
numbers of cancer cases, when corrected,
decrease from 320 to 4.6 per year for HFSA and from 3.4 to 0.05 per year for
pharmaceutical grade NaF(Refs. 2 and 9).
Similarly, for the analysis in which the petitioners evaluate an arsenic
concentration of 0.43 ppb due to HFSA and
0.00084 due to pharmaceutical grade NaF, the estimated numbers of cancer
cases, when 8 corrected, decrease from 1,800
to 25 per year for HFSA and from 3.4 to 0.05 per year for pharmaceutical
grade NaF (Refs. 2 and 9).
After making the correction (i.e., annualizing the lifetime cancer risk),
and retaining all other assumptions of the
petitioners analysis, the analysis actually indicates that the cost-benefit
ratio is in favor of using HFSA over
pharmaceutical grade NaF (-$81M/year to-$8M/year, respectively) rather than
pharmaceutical grade NaF over HFSA (Ref.
As a result, the information submitted by petitioners does not support the
petitioners’ claim that there are net
benefits in switching from HFSA to pharmaceutical grade NaF. Given that the
petition is based upon the premise that
the benefits of using pharmaceutical grade NaF as a fluoridation agent
significantly exceed the costs relative to the
use of HFSA as a fluoridation agent, EPA concludes that petitioners have not
set forth sufficient facts to establish
that HFSA presents or will present an unreasonable risk of injury to health
or the environment with respect to arsenic
or that it is necessary to initiate a TSCA section 6(a) rulemaking to
protect adequately against such risk.
Petitioners assert that HFSA contains lead but provided no data to support
Petitioners also assert that the use of HFSA in lead-containing water piping
systems results in leaching of lead from
lead-containing water piping systems into water (Ref. 5), and that when
chloramine is used in conjunction with
silicofluorides greatly enhanced leaching of lead into water occurs (Ref.
3). However, multiple other studies
concluded that the fluoridation of drinking water with HFSA has little
impact on corrosivity and/or release of metals
from plumbing materials (Refs.10,11,12, and 13).
For example, the Centers for Disease Control and Prevention (CDC) conducted
a study of the relationship between the
additives used for fluoridation (i.e., 9 HFSA, sodium silicofluoride, and
sodium fluoride) and blood lead
concentrations among a nationally representative sample of >9,000 U.S.
children, aged 1-16 years (Ref.10).
The study analysis did not offer support for the hypothesis that
silicofluorides in community water systems increase
blood lead concentrations in children.
Based on the available evidence, EPA cannot conclude that the use of HFSA,
with or without the presence of chloramine,
results in enhanced leaching of lead.
|fluoridation of Marin
Municipal Water District’s water is mandated by
two local ballot Measures and a state law.
MMWD started adding fluoride to its water in 1973 after a measure calling
for fluoridation on the November 1972 ballot passed with the support of 57
percent of voters. Marin voters reaffirmed their support for fluoridation by
giving 53 percent support to a local ballot measure in 1978.
Then in 1995, Assembly Bill 733 became law, requiring public water systems
that have more than 10,000 connections to provide fluoridated water as long
as they don’t use ratepayer funds.
The North Marin Water District, which provides water to
Novato and West Marin,
doesn’t fluoridate its water and does not fall
under the rules of AB 733.
“I can’t as a board member cast a vote that violates the law,” Gibson said.
“I’m not going to do that.”
