Two thirds of US tap water is fluoridated in the name of dental health, but concerned consumers fear unintended side effects.

Fluoride has made far more headlines than your average periodic table element…

In 1945, Grand Rapids, Michigan became the first US city to fluoridate the public water supply.  The idea quickly caught on, and the controversy began soon after: in growing numbers, a vocal minority has raised concerns about fluoride’s role in a broad range of health problems.  Fluoridation critics suggest fluoride exposure may be implicated in physical symptoms spanning gastrointestinal problems, low fertility, thyroid disease, endocrine disruption, arthritis, and cancer.  Government health advisors disagree, arguing the benefits to developing teeth outweigh any established risks.  Irrefutable evidence is hard to come by, due to the nature of the debate: in all major public health research, so many factors overlap that it can be impossible to either prove or disprove a condition’s cause.  And a controlled study (deliberately administering high doses of fluoride on selected humans for decades) would of course be unethical.

Recently, however, Harvard researchers were able to study health data for communities in China where high levels of fluoride are naturally present in the groundwater.  The resultsgive cause for unease: “the children living in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.”  The average difference was 7 points, and researcher Philippe Grandjean concluded that fluoride belongs among lead, mercury, and other poisons as a known neurotoxin and “chemical brain drain.”  Grandjean suggested the developing brain may be irreversibly damaged by fluoride exposure, and the exact “safe” thresholds, if any, are unknown.

More and more of us are ready to opt out of fluoridation.  But how can we take out these minuscule, tasteless molecules added at the treatment plant?  If you’re serious about going fluoride-free, here are a few things to consider.

What Doesn’t Reduce Fluoride Exposure

  • The most popular water filters — the inexpensive activated-carbon pitchers and tap-attachments sold under the brand names Brita and Pur — can’t remove fluoride.
  • Boiling your water won’t help, as the fluoride does not evaporate easily like chlorine; as the   volume of water decreases through boiling, the fluoride concentration actually goes up.
  • Be aware that black and green tea as well as rooibos or “red tea” all contain high levels of natural fluoride; these beverages also provide beneficial antioxidants, but if you’re concerned that your overall fluoride intake may be excessive, consider reducing your tea consumption.
  • Processed beverages and foods, non-stick cookware, some pharmaceuticals, non-organic grape juice and wine, and of course fluoride toothpaste will all increase your overall fluoride consumption.

Home Fluoride-Removal Systems that Work

remove-fluoride-03
Berkey Water Purification System with PF2 Fluoride Filter

  • Low-tech: attractive countertop unit needs no hookups to plumbing or electrical systems.
  • Filters can be cleaned and reused for maximizing sustainability and cost-effectiveness.
  • Portable, can be used in the kitchen or off-grid to filter untreated water such as ponds and streams.
  • Broad-spectrum: gravity-fed micro-porous filtration removes pathogens, volatile organic compounds, synthetic organic chemicals, MTBE, arsenic, heavy metals, and physical contaminants from water.

This unit is our favorite because of its versatility, earth-friendliness, and overall effectiveness.  Note that the optional PF2 must be added for fluoride removal, as the Berkey on its own does not take out fluoride.

Reverse Osmosis

Cons:

  • RO systems are expensive ($200-$600 for basic home models, plus $50 filter changes 1-2 times per year), and discounted department store models may use inferior membranes, compromising performance.
  • Systems require electricity to run, adding to expense and fallibility.
  • RO filters often require a technician to install, if consumer is not experienced with plumbing.
  • The RO process discards 3-5 gallons of water for every gallon filtered.

The massive waste of water alone leads us to feel reverse osmosis is not a sustainable solution for an increasingly drought-ridden time, when every drop of potable water should be considered a precious resource.

Activated Alumina

  • Frequently used in large-scale water treatment where excessive fluoride in groundwater is a problem.
  • While promoted to remove over 90% of fluoride at home, pH needs to be low and flow needs to be slow in order to achieve goals.
  • Frequent cartridge replacement to maintain effectiveness adds to initial costs.
  • Many variables make results uncertain, and repeated testing would be required to monitor system performance.

The Survival Still Water Purifier and Desalinator

  • Turn to the Survival Still when you want to be prepared for any and all possibilities, including disasters.
  • This unit can make consistently pure water from any source in an emergency, even swimming pools, ponds, or seawater.
  • Removes all contaminants including radioactive isotopes and organic pathogens.
  • Requires some energy source to boil water, but no electricity.  Works with your kitchen pots for easy storage.

Make your own solar still

  • For the adventurous and mechanically inclined, experimenting with making your own solar distiller can provide an interesting challenge.
  • Distilled water has been stripped of beneficial minerals as well as contaminants; health advisers disagree about the risks and benefits of drinking distilled water.

For those of us without the time or skills to devote to plumbing and construction, a reasonably priced and effective home filter system can seem the holy grail of clean, worry-free water.

Buying Water

  • Bottled water has been largely rejected by the environmental movement as representing a massive waste and mismanagement of resources in production, transport, and packaging.
  • Buying filtered water from water services or local stores (using reusable containers to fit a water dispenser) can be a short-term solution.  But most home filter systems will quickly pay for themselves, take up less space in your kitchen, and provide a more reliable clean water source.
  • Some packaged “spring water” can actually contain fluoride and other questionable minerals, so always review the water analysis carefully before buying.

It’s getting harder and harder to take a cool drink of water for granted.  Across the country, battles continue to rage in communities large and small over whether adding fluoride to the public water supply is a safe, common-sense public service, or a sinister act of government-sponsored health endangerment.  In Portland, Oregon, the impassioned debate centered around issues of personal choice and responsibility: if the facts are in question, who gets to decide what’s in their water?

Ultimately, Portlanders voted “no” to fluoride.  It’s a decision each family must make based on available information.  If your municipal water supply or private well contains unwanted fluoride, you have options to exercise your informed choice in your own home.

    Dallas, Texas voted to remove fluoride from their drinking water!

  • Jason Forest

    great tips! i really appreciate this great post. looking forward to your next blog

    Water is essential for health, hygiene and the productivity of our community. water treatment process may vary on the water condition that you have in your area. its better to invest on a good water treatment. it will benefit you by providing safety to you and your family.

    Every city should allow it’s citizens to make the choice to not fluoridate their water system. Fluoride gets stronger when you heat the water so, cooking or bathing in it sounds fun doesn’t it? They don’t tell you this but when you find this out, it’s disgusting considering all the other chemicals and drugs that ride in on your tap water to keep it clean for drinking.

    I buy Whole Foods RO spring water by the gallon to cook and drink. It isn’t suppose to have Fluoride in it.

    Supposedly, it’s all for low income families benefit who supposedly don’t go to the dentist. Do they actually know this for a fact? Education and dental preventative measures for all people are better than fluoridating them like sheep! I bet even low income people would choose to forgo the fluoride than know they’re drinking it for a lifetime.

    There is no evidence fluoride has any benefit on dental health. Remember, this is being put in our water by the same people who corroborate with the banks to control society. If you think for a second there is a single health benefit of poisoning your water supply with fluoride then you are out of your mind.

    • Sarah Walton

      I agree Brick. Where do you live? I wish Brisbane, Australia, had given Queenslander’s a choice because the majority of us said no to flouride. What humans subject eachother to for the sake of greed is unbelievable and F’d up!!

        Can someone please tell me . . .”HOW” does ingested Fluoride protect the outer layer of the teeth? If it’s ingested, it’ll feed the inner tooth and not the outer, I understand there’s been research to show that Fluoride actually reduces bone density when ingested? What the heck are our politicians and local advisors doing to us?

        I’d like to know what’s the benefit of polluting our water? Why don’t the big pharma’s produce a fluoride pill, so that those in favour of ingesting this poison can take it knowingly. Maybe saving money by not putting it into our drinking water, could fund the purchasing and supply of fluoride pills to those wishing to take them daily.

        I wonder how many of our politicians & advisors would subscribe to regular pill taking of this terrible substance if they had to swallow it every day to “protect” their teeth? And would they recommend Fluoride pills to their children and families?
