This essay is the final essay in a series of three essays around the documentary TAPPED.

 

TAPPED:  Bisphenol A

 

In the documentary TAPPED, Dr. Frederick Vom Saal says Bisphenol A, or BPA, is “one of the most toxic chemicals known to man.”  BPA, explains Vom Saal, is “the poster child chemical that is going to dismantle the entire regulatory process and demand a re-analysis of all chemicals.”  “BPA,” says Vom Saal, is “frightening to the regulatory community because of the magnitude of the error they have made.”    

BPA leaches into water from water containers made of hard, polycarbonate plastic, stamped with #7 on the bottom of the product.  Examples of problem water containers are the five-gallon hard plastic water jugs used with water cooler systems, baby bottles, and sports bottles. 

Other examples in the general food system include containers for liquid baby formula and the linings of beverage and food cans.  Elaine Shannon of the Environmental Working Group (EWG) reports that because plastics made with BPA “break down easily when heated, microwaved, washed with strong detergents, or wrapped around acidic foods like tomatoes, trace amounts of the potent hormone leach into food from epoxy lacquer can linings, polycarbonate bottles and other plastic food packaging” (Shannon, “What the Chemical Industry Doesn’t Want You to Know,” September 2008, http://www.ewg.org/report/what-chemical-industry-doesnt-want-you-know).  Wikipedia notes that as of April 2010, General Mills had developed a BPA-free alternative can liner that works even with tomatoes.  But, writes Wikipedia, General Mills is only planning on using this new liner with their organic food subsidiary, Muir Glen (http://en.wikipedia.org/wiki/Bispjhenol_A).   

Polycarbonate plastics are ubiquitous today.  BPA, explains Wikipedia, is used in “sports equipment, medical and dental devices, dental fillings and sealants, eyeglass lenses, CDs and DVDs, and household electronics”—like, notes, computers and cell phones.  BPA, details Wikipedia, is used to make other plastics; it’s a “precursor to the flame retardant tetrabromobisphenol A”; it was “formerly used as a fungicide”; it’s the “preferred developer in carbonless copy paper and thermal paper,” including sale receipt paper; it’s used in foundry castings and to line water pipes”   

BPA mimics estrogen in the body, which is something scientists have known since 1930.  Regulatory bodies have determined what they believe to be safe levels for humans by using an idea, explains Vom Saal, dating from the sixteenth century:  “the dose makes the poison.” 

However, Vom Saal says this premise is false for any hormone and explains that  recent studies are showing that even minute levels of BPA are unsafe. 

Vom Saal says in TAPPED that 700 peer-reviewed, published studies show BPA to be dangerous.  He explains that the 38 internationally recognized scientists who served on a 2006 National Institutes of Health panel (Chapel Hill) determined that current levels of BPA pose risks for humans.  Shannon notes in “What the Chemical Industry Doesn’t Want You to Know,” that The National Toxicology Program accepted much of the Chapel Hill panel’s thinking and wrote that low doses of BPA may affect development of the prostate gland and brain and may cause behavioral effects in fetuses, infants, and children.

Shannon notes that Vom Saal, working with Wade Welshons at the University of Missouri-Columbia, “turned up the first hard evidence that miniscule amounts” of BPA “caused irreversible changes in the prostates of fetal mice” in 1997, or 14 years ago.  By 2008, writes Shannon, the global chemical industry was producing 6 billion pounds of BPA annually, which generated “at least $6 billion in sales” 

In order to protect its BPA turf, the chemical industry has followed the very successful tobacco industry model, which Devra Davis details in THE SECRET HISTORY OF THE WAR ON CANCER (2007).  The tobacco industry spent astonishing amounts of money to advertise tobacco use, to delay negative decisions, to hide negative science, to craft favorable legal decisions, to obfuscate science with problematic studies from paycheck scientists, and to fire or discredit anyone saying tobacco use was unhealthy.  The chemical industry is currently running what Shannon calls a “scorched earth” campaign that includes such actions as an “industry email to food banks charging that a BPA ban would mean the end of distributions of canned goods for the poor.”  

Vom Saal describes in TAPPED how a representative from Dow Chemical Company showed up in his and Welshons’ Missouri lab to dispute the data and to declare “`we want you to know how distressed we are by your research.’”  Vom Saal revealed that Dow tried to stop papers critical of BPA from being published.  Shannon describes how the American Chemistry Council attempted to prevent Vom Saal from speaking at a convocation at Stanford University because his work was “`very controversial, and not everybody believes what he’s saying.’”  Shannon quotes Welshons as saying that chemical industry officials made “` blatantly false statements about our research’” and “`they were skilled at creating doubt when none existed.’ “

TAPPED shows footage from a Senate hearing investigating the Food and Drug Administration’s (FDA) use of biased studies produced by the chemical industry’s paycheck scientists.  Senator John Kerry castigates FDA’s Dr. Norris E. Alderson for not asking for independent studies.  Senator Kerry concludes that the FDA is not protecting citizens, and TAPPED concludes that industry has captured the FDA and other regulatory agencies. 

Lyndsey Layton of “The Washington Post” reported that as of 2009, 93 percent of the U.S. population had detectable levels of BPA in their urine (“High BPA levels linked to male sexual problems,” November 11, 2009, http://www.washingtonpost.com/wp-dyn/content/article/2009/11/10/AR2009111017411).  Layton’s article discusses a November 2009 study of 634 male workers from four factories in China showed that exposure to high levels of BPA caused erectile dysfunction and other sexual problems after a few months on the job. 

Vom Saal, in TAPPED, links the following health problems to BPA:  childhood diabetes, obesity, prostate and breast cancers, brain disorders like ADHD, liver disease, ovarian cancer, uterus disease, and low sperm count in men.  Layton lists infertility in general and early-onset puberty. 

Shannon discusses some of the dozens of other scientists who are also studying BPA and who concur with Vom Saal and Welshons.  Patricia Hunt, a reproductive scientist (molecular biologist) from Washington State University, was stunned by what she saw under her microscope after a caustic floor detergent used to clean her lab released BPA into her animals’ food and water.  Hunt said “`Like most Americans, I thought, my government protects me from this kind of stuff.”  She began studying BPA, and, after a decade, determined that “exposure to low levels of BPA—levels that we think are in the realm of current human exposure—can profoundly affect both developing eggs and sperm.” 

A Yale University medical school research team led by Csaba Leranth discovered that BPA affects the neurological system in African green monkeys.  In humans, reported team member Tibor Hajszan, the devastating effect on synapses in the monkey brain could translate to memory and learning problems and depression.      

In September 2010, Canada banned BPA as a toxic substance.  Eight states have banned BPA in children’s’ products:  California, Connecticut, Maryland, Minnesota, New York, Vermont, Washington, and Wisconsin.  In October 2010 the Maine Board of Environmental Protection held hearings on a ban on BPA in baby bottles and sippy cups.  The Board postponed any decision until it studied expanding the ban.

Here’s what you can do:  don’t wait for our government to protect you.  Don’t buy canned foods or beverages unless the container says “BPA free,” avoid the combination of plastic and foods, don’t heat plastic, and don’t reuse plastic containers.  Do buy, cook, and preserve locally grown, organic, nutrient-dense whole foods available in your region.

Mainely Tipping Points 23: TAPPED: Bottled Water

Mainely Tipping Points 23

Note:  This essay is the first in a series of 3 essays on water, which started with viewing the documentary TAPPED and reading Elizabeth Royte’s BOTTLEMANIA.

TAPPED:  BOTTLED WATER

The movie TAPPED demonstrates that drinking water and bottled water are much more complex issues than I had realized.  I had been somewhat aware of industry’s ongoing attempts to commodify water.  I was aware that an argument was raging about whether access to drinking water is a human rights issue.  (Only one percent of available water worldwide is drinkable.)  Apparently the World Bank places the global water market’s value at $800 billion. 

I was beginning to hear more arguments about local watersheds being part of the public “commons.”  Indeed, TAPPED  begins with the history of Nestle massively pumping water from local springs in the Fryeburg, Maine, area, bottling it, and selling it under the Poland Springs label.  This pumping is draining the local watershed.  The Fryeburg municipal water system has experienced periods when its system goes dry suddenly.  And, the property values of local people living alongside a steadily diminishing lake have dropped.  Nor is Fryeburg benefiting financially as Nestle’s business is wholly private. 

Battles like the one between Nestle and the citizens of Fryeburg are happening in small communities all across the United States as industry tries to legally define its control of local water.  Nestle alone sells the following regional brands:  Ice Mountain, Zepher Hills, Deer Park, Ozarkia, and Arrowhead.  By 2007, bottled water in America had become a $11.5 billion business for, mostly, three big corporations:  Nestle, Coke, and Pepsi.    

Much bottled water is pumped from municipal tap water (40 percent) or its sources.  Industry then sells tap water back to consumers at 19 times the cost of their tap water.  Remember, those same consumers have already paid municipal water taxes. 

Sometimes, industry pumping of municipal water occurs nonstop during severe droughts where local people are living with necessarily stringent water mandates.  Pepsi pumped 400,000 gallons a day of municipal water in Raleigh, NC, during the 2007-2008 drought.  Coke, during Atlanta’s 2007-2008 Level IV drought, pumped 118 million gallons of water from a local lake source of Atlanta’s water.  The pictures in TAPPED of what’s left of this lake show the enormity of what has occurred. 

Industry employs both misleading bottle labels suggestive of pure water and expensive advertising campaigns to convince citizens that bottled water is cleaner than tap water.  Barbara Lippert, an Adweek Media critic, observed in TAPPED:  “Bottled water is the greatest advertising and marketing trick of all time.”  And Susan Wellington, president of Quaker’s U. S. beverage division, is quoted in TAPPED saying that “when we’re done, tap water will be relegated to showers and doing dishes.”        

But, is bottled water safe?  TAPPED covers the three major issues:  the nonexistent government regulation of bottled water, the water inside the bottle, and the bottle itself.  The latter two issues conflate since the bottle can and does taint the water it contains.

First, bottled water is largely unregulated.  The Food and Drug Administration (FDA) has no jurisdiction over bottled water produced and sold inside a single state.  It’s no accident that most bottled water is produced and sold within single states; that’s why there are so many local brands.  Further, the FDA has only one person overseeing all regulations over bottled water, and that person has other responsibilities as well.  Also, the bottled water industry is not required to submit reports to the FDA and is not required to report internal testing.   

Tap water, on the other hand, is highly regulated and is tested many times a day.  Yes, it may contain fluoride and chlorine mixtures, but those chemicals can and should be filtered out.  And, the practice of adding fluoride—a known toxin—could be stopped. 

Second, TAPPED reports that the National Resources Council tested the water in over 1,000 bottles of water and found bacteria and chemicals, including arsenic, in unsafe levels.  Another independent test of seven brands in two separate labs was analyzed by Dr. Stephen King, an epidemiologist and toxicologist at the University of Texas.  Dr. King found the results to be “horrifying.”  The labs found benzene, vinyl chloride, styrene, and toluene—all highly dangerous carcinogens which are also capable of adverse reproductive outcomes.  Toluene, used in gasoline and paint thinner, is a neurotoxin. 

The two labs found three different types of phthalates, all of which pose dangers to unborn babies and to both males and females.  Phthalates are endocrine disrupters.  Dr. King said bottled water was particularly risky for pregnant women and young children.  Plus, as TAPPED documents, there have been many bottle water recalls over the years.

The water bottles themselves have major issues.  Extreme health problems occur within people living near manufacturing plants, the toxicity of the bottles’ material components is not fully known, and the pollution caused by careless bottle disposal is colossal. 

Eighty percent of plastic water bottles are made from polyethylene terephthalate derived from crude oil.  Labeled PET or PETE on the bottom of the bottle, this chemical is in the benzene family.  Devra Davis, in THE SECRET HISTORY OF THE WAR ON CANCER (2007) devotes many pages to the terrible dangers for humans from the benzene family and from vinyl chloride.  So, when we buy a water bottle, we become partners with industry in harming people living near manufacturing plants or working within them.   

The 2007 work of William Shotyk, director of the Institute of Environmental Geochemistry at the University of Heidelberg in Germany, shows that PET bottles leach a deadly toxin called antimony which has chemical properties similar to arsenic (Randy Richmond, “Toxin leaches into bottled water in PET containers,” http://medicine.org/toxin-leaches-into-bottled-water-in-pet-containers; Adam Voiland, “The Safety of PET Bottles, July 26, 2007, U.S. News and World Report News). 

Antimony can cause headache, dizziness, and depression in small doses.  In large doses, it is lethal in a few days.  PET bottles, Shotyk reveals, continuously shed antimony, so the longer water is in the bottle, the higher the levels of antimony. 

Critics pose that the levels of antimony are below accepted safety levels, but recent work on Bisphenol A (BPA) by University of Missouri-Columbia scientists Frederick Vom Saal and Wade Welshons shows that miniscule amounts of BPA are dangerous for humans.  BPA, note, is used to make hard plastics, like the 5-gallon water bottles used in water coolers and baby bottles. 

So, in short, we do not know exactly how dangerous antimony is or if other chemicals are being leached into bottled water on a regular basis.  Additionally, Wikipedia analysis poses that antimony might be an endocrine disrupter.   

Reusing plastic water bottles is not wise.  Water bottles with narrow necks makes washing difficult and can result in both the build-up of unsafe bacteria levels and in increased leaching of toxic chemical from the plastic.  

Third, Americans consume 80 million single-serving bottles of water daily, but only 30 million end up in landfills.  Once in landfills, municipalities and taxpayers—not industry–have to pay to process them.  The rest of the bottles—50 million of them daily–are massively polluting the environment, especially the oceans.  (

States with bottle deposits do get more returned bottles, but they still have to fund disposal.  This situation is a classic example of how industry externalizes its costs.  And, I’m beginning to understand that if a product is cheap, elsewhere, other people are paying personally the actual costs of production.  

I bought a stainless steel water bottle with a narrow neck a few years back.  But, it seems, some metal bottles have plastic coatings inside.  I’m going to replace this bottle with one of the glass water bottles that has a reinforced webbing on the outside that helps prevent shattering.

One thing is for sure:  I’m never buying bottled water again.
