Working for fluoride-free water, and practical, nontoxic solutions to children’s oral health challenges

May 2018: We join Fluoride Action Network in its Moms2B campaign, to alert pregnant women to the most recent scientific evidence that consuming fluoride, whether from fluoride supplements, or from fluoridated water, can harm the developing brains of their unborn children. Don’t risk your child’s future. Learn more here: http://fluoridealert.org/issues/moms2b/

“As of June 2018, a total of 60 studies have investigated the relationship between fluoride and human intelligence, and over 40 studies have investigated the relationship fluoride and learning/memory in animals. Of these investigations, 53 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while 45 animal studies have found that fluoride exposure impairs the learning and/or memory capacity of animals. . The human studies, which are based on IQ examinations of over 15,000 children, provide compelling evidence that fluoride exposure during the early years of life can damage a child’s developing brain. – From Fluoride Action Network, Fluoride & IQ: The 53 Studies

The first U.S. Government-funded study investigating prenatal neurological damage from fluoride, Prenatal Fluoride Exposure and Cognitive Outcomes in Children at 4 and 6–12 Years of Age in Mexico, finds that each 0.5 part per million (ppm) increase in a pregnant woman’s urine fluoride levels reduced her child’s IQ by 2.5 – 3 points.

The full peer-reviewed study,  a 12 year analysis of data from 287 mother-child pairs, was published in the journal Environmental Health Perspectives (9/19/2017), and can be downloaded at the U. S. National Institutes of Health (NIH) website: https://ehp.niehs.nih.gov/wp-content/uploads/2017/09/EHP655.alt_.pdf

The new study is unique in approach, size, and duration, but it joins over 50 other human-based studies finding evidence of fluoride-based cognitive damage affecting IQ…  READ THE ARTICLE.

2018 Sonoma County Supervisors (left to right): Susan Gorin (District 1), James Gore (District 4), Shirlee Zane (District 3), Lynda Hopkins (District 5), and David Rabbitt (District 2)

THE SONOMA COUNTY BOARD OF SUPERVISORS has postponed indefinitely any consideration of the Sonoma County Department of Health Services (DHS) proposal to fluoridate Sonoma County water (originally on the Sonoma County Board of Supervisors agenda 5/19/2015). As of the 2016 elections,  a majority of Supervisors is on the record opposing fluoridated tap water for Sonoma County.

LOOKING AHEAD, Sonoma County residents should be heartened because three Sonoma County cities, Cotati, Sebastopol, and the City of Sonoma, and a non-municipal water district,  Valley of the Moon, have officially rejected fluoridation, which, due to a unanimity requirement in the Sonoma County Water Agency Restructured Agreement for Water Supply,  should prevent future attempts to fluoridate through  SCWA.

SANTA ROSA: The Sonoma County Department of Public Health has declared a renewed focus on fluoridating the City of Santa Rosa (announced at the second annual Sonoma County Dental Health Summit, 9/25/2016), although no traction has yet been gained.

THE CITY OF HEALDSBURG remains fluoridated. For information and updates, visit Safe Water Healdsburg online.


NORTH MARIN WATER DISTRICT remains unfluoridated due to the full committment of the NMWD Board of Directors, which is grateful for Clean Water Sonoma-Marin’s successful efforts to stop attempts to fluoridate through the Sonoma County Water Agency. 80% of NMWD water, including water for the City of Novato, is provided by SCWA.

MARIN MUNICIPAL WATER DISTRICT (MMWD) remains fluoridated. Clean Water Sonoma-Marin is holding individual meetings with Marin Municipal Water District board members. The good news is that we are talking at last, not just limited to three minute comments at MMWD Board meetings.

Grant Colfax

GRANT COLFAX, MD, was appointed Director of the  Marin County Department of Health & Human Services in April 2015.  At the time, the Marin Independent Journal profiled the new director, reporting that Colfax, a health policy expert who served as head of the White House Office of National AIDS Policy, will oversee 700 employees and a $160 million budget at the Health and Human Services Department at the Civic Center… The 50-year-old Colfax, whose 18-year career in public health included heading HIV prevention efforts for San Francisco, served as President Obama’s top AIDS policy adviser from 2012 to 2014, when he left to lead global HIV and tuberculosis efforts for the nonprofit Programs for Appropriate Technology in Health… Colfax grew up on a Mendocino County goat farm, where he was homeschooled. His mother, an English teacher, and father, a Mendocino County supervisor, provided breeding stock for local dairies. He holds a 1987 bachelor’s degree from Harvard College and is a 1993 graduate of Harvard Medical School. He completed his medical residency at the University of California at San Francisco before joining San Francisco’s Department of Public Health in 1997 to direct HIV clinical prevention studies for seven years… Read the full Marin IJ article by Nels Johnson. Dr. Colfax’s door is always open to Marin County residents with concerns about health issues, including health and human services programs and policies.

BECAUSE COMMUNICATION IS ESSENTIAL, Clean Water Sonoma-Marin members , including medical professionals, are in contact with Dr. Colfax, and with Marin County Public Health Officer Matt Willis, MD, MPH. In the fall of 2017, a cordial meeting was arranged by Dennis Rodoni, current member of the Marin County Board of Supervisors, and former North Marin Water District Board Member.

Dennis Rodoni

A second meeting was arranged by Supervisor Rodoni in January 2018. Although Dr. Colfax was unable to attend, Dr. Willis met with Supervisor Rodoni, and other Marin County Clean Water advocates, Ginger Souders-Mason,  Deborah Landowne, Steve Lamb, CWSM Director Dawna Gallagher-Stroeh , thyroid specialist Dr. Richard Shames, MD, and Marin Municipal Water District Board Member, attorney Larry Bragman, who explained the current suit in Federal Court against EPA on the issue of fluoride neurotoxicity. Brian Smith DDS, and Bill Osmunson DDS, MPH participated in the meeting via letters to Dr. Colfax and Dr. Willis.

Matt Willis

As with all Public Health professionals, Dr. Willis is tasked with implementing and supporting Public Health policies, including water fluoridation. However, Dr. Willis said, of all the concerns about water fluoridation presented at the meeting, the one that gives him pause is the issue raised in the letter from Dr. Osmunson, the possiblilty that, with increasing fluoride exposure from many sources, Marin County residents might be receiving too much fluoride.

THE HEALTH COUNCIL OF MARIN is looking into the new data on fluoride toxicity. We have been contacted,  and are providing documents as requested. The Health Council operates under Marin County Health & Human Services (HHS), and is responsible for advising the Marin Board of Supervisors, and Marin HHS on health issues, and advocating “for the development and allocation of resources to assure quality and accessible health care, and to educate regarding issues affecting the health and well-being of the citizens of Marin County.” Source: https://www.marinhhs.org/boards/marin-health-council


Jay Kumar

Jay Kumar, DDS, MPH, California’s first Director of Dental Health, was instrumental in setting up a pilot program, now in effect in New York State, in which millions of dollars in Medicaid funds now support water fluoridation. The program, which siphons off scarce funds from effective dental health care, is a first step in an ambitious plan to use Medicaid funds to pay for water fluoridation infrastructure, engineering, and chemicals costs nationwide.  Dr. Kumar is in discussion with public health officials and key legislators, about a similar program for California.

On November 23, 2016, the International Academy of Oral Medicine & Toxicology (IAOMT), and Fluoride Action Network (FAN), in coalition with others, hand delivered a petition to US EPA, accompanied by over 2,500 pages of scientific documentation, to ban the use of fluoridation chemicals because of the neurotoxic risks of fluoride ingestion.

Historically, when a chemical has evidence of neurotoxicity, for example lead, EPA has banned its use. Since 2014, fluoride has been on EPA’s short list of chemicals, including arsenic and lead, with scientific evidence of developmental neurotoxic harm to humans.

EPA rejected the petition (2/27/2017) and, in response, the petitioners filed a complaint in Federal Court (4/18/2017), seeking a ban on water fluoridation, under Section 21 of the Toxic Substances Control Act (TSCA).

EPA responded with a motion to dismiss “all claims in the present matter”(11/30/2017). The EPA motion to dismiss was rejected by the judge (12/21/2017), and the suit is now moving ahead in Federal Court in San Francisco.

“This case will present the first time a court will consider the neurotoxicity of fluoride and the question of whether fluoridation presents an unreasonable risk under the Toxic Substances Control Act (TSCA).  And, in contrast to most other legal challenges of Agency actions, TSCA gives us the right to get the federal court to consider our evidence ‘de novo’—meaning federal courts are to conduct their own independent review of the evidence without deference to the EPA’s judgment.”  – attorney Michael Connett

For brief background on the petition, a detailed timeline, including links to all filings and rulings to date, and the names of petitioning organizations, and their attorneys, please read: Petition to EPA & Lawsuit on Fluoride Neurotoxicity.

The suit has survived US EPA’s challenges, and will be heard in Federal Court in San Francisco, in 2019. We’ll keep you posted.

H.R. 2422, the Action for Dental Health Act of 2017,  would have authorized fluoridation promotion programs through 2022 and would have cost taxpayers 160 million dollars. Congratulations! You helped stop that waste. Because of Sonoma County emails and calls to our Members of Congress, added to messages from concerned citizens across the country, including some of us who went to Washington DC to talk with Congressmen and staff members in person, H.R. 2422 was withdrawn. Thank you for a strong, speedy, effective response! The ADA has proposed and lobbied for similar bills in the past, and we’ve stopped them. When bills like this come up again, you’ll know. Together, we’ll stop those too. – Stuart Cooper [See Stuart’s article in the October 2017  issue of the Sonoma County Gazette, “Take Action: Stop or Amend H.R. 2422.”]
