Toxic Chemicals
Added To Our Drinking Water
In this era of relatively enlightened health and clean-water
awareness, it is astounding that we are purposefully adding to
our water other
chemicals that have been proven in numerous studies to have severe
negative health impacts.
Let’s take a look at two common
controversial chemical additives.
Fluorine
Fluorine is one of the most abundant elements on earth. In its
elemental form, fluorine is a pale yellow, highly toxic and corrosive
gas. In nature, fluorine is found combined with minerals as fluorides.
Not accounting for industrial fluoride pollution and water fluoridation,
probably everyone is exposed to some form of fluorine. Most human
exposure to fluorides prior to sixty years ago was primarily from
sources such as naturally fluoridated drinking water, seafood and
fluoride in fruits and vegetables from the soil. However, over
the past sixty years, there has been a dramatic expansion of the
industrial, domestic, agricultural and medical usage of fluorine-based
products and the average person's exposure has increased exponentially.
The industries that contribute to fluoride pollution include general
manufacturing, phosphate fertilizer production, aluminum smelting,
uranium enrichment facilities, coal-burning and nuclear power plants,
incinerators, glass etching, silicon chip manufacturing, plastic
manufacturing, and petroleum refining. Fluorine-based agricultural
products (insecticides and fungicides) and fluorine-based medications
add to the contamination. And up to sixty percent of the population
drinks some form of fluorine purposely introduced into the drinking
water as a public health measure.
Ingestion of fluorine may lead to a condition called “fluorosis,” also
known as “Reservoir Based Disease.” This may occur
when a person drinks water with an excess of more than 1-ppm (part
per million) fluorine content. In dental fluorosis, the teeth lose
their shine as fluorine removes the their enamel coating. They
gradually acquire mottled brown and yellow spots, loosen in their
sockets and fall out. In skeletal fluorosis, there is abnormal
bone growth at the joints, causing the long bones to become bowed
and painful. Other symptoms of fluorosis include loss of appetite
and sterility.
One Federal agency, the U.S. Agency for Toxic Substances and Disease
Registry, lists fluorine compounds and fluorides as one of the
top 20 of 275 substances that pose the most significant threat
to human health. The agency goes on to enumerate the dangers, including
bone cancer, brittle bones, stomach pain, vomiting, diarrhea, sterility,
and possible birth defects.
Yet, in spite of hundreds of studies emphasizing the severity
of fluoride pollution, the U.S. Public Health Service states: "There
are health and economic benefits from water fluoridation for people
of all ages and social and economic groups, especially for children
who do not get adequate dental care."
Yes, fluoridation has been shown to prevent dental cavities.
However, one of the key issues surrounding fluoridation is that
it deprives
the individual of the right of freedom of choice in a matter of
personal health care. It imposes an inescapable, demonstrably toxic,
prophylactic treatment on each person in the community for a non-contagious
condition, regardless of his or her desire to be so treated. The
water supplier has the responsibility to make the water as safe
as possible to drink, not to make it a vehicle to affect the body
of the consumer.
Fortunately, for the present, we don’t have to worry about
fluorine added to Hawaii public water supplies. In an enlightened
move that health-conscious residents and civil libertarians applaud,
the Hawaii legislature in February banned the addition of fluoride
to our drinking water supply. Stay tuned.
Chlorine
In the United States, chlorine is added to public drinking
water supplies as a public health measure to kill harmful bacteria
in
the water. The added chlorine reacts with naturally occurring organic
matter in the raw water creating a host of chlorinated chemicals
as by-products. A number of these chlorinated by-products, called
trihalomethanes or organochlorides, have been shown in study after
study to create a number of serious health problems, including
bladder and rectal cancers, immune problems, and fertility and
developmental disorders. These chemicals are not easily broken
down by the body’s detoxification systems and are generally
stored in the fatty tissues of the body (breast, other fatty areas,
mother's milk, blood and semen). Organochlorides can cause mutations
by altering DNA, suppress immune system function and interfere
with the natural controls of cell growth. This has led to several
studies linking chlorinated water with serious birth defects, like
spina bifida.
Other studies report that chlorinated tap water irritates
the skin and can be a primary cause of eczema. Chlorinated water can
also destroy polyunsaturated fatty acids and vitamin E in the body
while generating toxins capable of free radical damage (oxidation).
This might explain why supplementation of the diet with essential
fatty acids like flax seed oil, evening primrose oil, borage oil
and antioxidants like vitamin E, selenium and others helps so many
cases of eczema and dry skin.
Chlorinated water also destroys much of the beneficial
intestinal flora, the “friendly bacteria” that aids in the digestion
of food and protects the body from harmful pathogens. Beneficial
intestinal bacteria are also responsible for the manufacture of
several important vitamins like B12 and K. It is not uncommon for
chronic skin conditions like acne, psoriasis, seborrhea and eczema
to clear up or to be significantly improved by switching to unchlorinated
drinking water and supplementing the diet with probiotics like
acidophilus and bifidus.
In light of the veritable mountain of evidence showing chlorinated
water to be dangerous, why is chlorine still used as the primary
bacterial control in our water supply?
It’s all about money. Several years ago, the Environmental
Protection Agency had the gumption to suggest that a study be launched
to determine how feasible it would be to move away from chlorine
water treatment. But even a gradual policy shift from a
chlorine-based system to alternative methods was perceived as an
assault on the
chemical industry which has shown itself to be politically powerful
and influential against such thinking. So the Chemical Manufacturers’ Association
and the Chlorine Institute turned on the heat and the government
backed down. The chemical industry also strongly protects current
EPA policy, which involves some minor toxicological testing and
population studies to measure the effects of certain pollutants.
But the word on chlorinated water is out and many European
cities, and some Canadian cities, such as Ottawa, have long ago
turned
away from chlorination in favor of ozonation to disinfect their
water. In recent years, a few smaller American cities like Emporia,
Kansas and Littleton, Massachusetts, have also begun to use ozonation. The huge Santa Clara Valley Water District in California has announced
that it is switching to ozonation over the next 5 to 8 years, as
has the city of Las Vegas, Nevada.
Still, the vast majority of water supplies in the U.S. remain
chlorinated.
A number of filtering and water purification systems can remove
chlorine from your water. In a previous column, I discussed the
home water purification options. Your health care practitioner
can assist you in making an informed choice. Don’t forget
to add a shower filter – the chlorine fumes absorbed from
a 10-minute shower are equivalent to the chlorine ingested in an
eight-ounce glass of water.
