The
causes of water contamination are numerous and range from agricultural
runoff to improper use of household chemicals and everything in between.
While the standard use in our society of over 75,000 different chemical
compounds has offered added convenience and productivity in our lives,
it has also come at a tremendous price… drastic increase in degenerative
diseases. In the early 1900s, before chlorine, pesticides, herbicides
and the tens of thousands of other chemicals that we are exposed to, the
average person had a 1 in 50 chance of getting cancer , today 1 in 3 can
expect to get cancer in their lifetime, one out of every 2 men.
Our use of man made chemicals has become so extreme
that we can now find traces of these low level toxins in virtually every
public water supply in the world. A recent report by the Ralph Nader
Study Group, after reviewing over
10,000 documents acquired through the Freedom Of Information Act, stated
that “U.S. drinking water contains more than 2100 toxic chemicals
that can cause cancer.” The Federal Council On Environmental Quality
reports that “Up to two thirds of all cancers may be attributed to these
low level toxins.” and that “once contaminated our ground water will
remain so for tens of thousands of years… if not geologic time!”
Our tendency is to blame it on the big factory up
stream. And while industry has certainly played its part in our water
contamination problems, it is “us” individuals that are the most to
blame. The majority of the contaminants found in our drinking water can
be traced back to improper or excessive use of ordinary compounds like
lawn chemicals, gasoline, cleaning products and even prescription drugs.
Once we realize that everything that goes down the
drain, on our lawns, on our agricultural fields or into the environment
by any means… eventually winds up in the water we drink, we begin to see
just how fragile our water supplies really are.
Our municipal water treatment facilities are not designed or
effective for removing these synthetic chemicals and typically only
consist of sand bed filtration and disinfection, much like a standard
swimming pool filter. For the most part today’s water treatment
facilities are much the same as they were at the turn of the century.
“Drinking water plants are old and out of date, and water supplies are
increasingly threatened by and contaminated by chemicals and
microorganisms.” Natural Resources Defense Council. “The way we
guarantee safe drinking water is broken and needs to be fixed.” Carol
Browner, U.S. EPA
One of America’s leading authorities on water
contamination, Dr. David Ozonoff of the Boston University Of Public
Health warns that, “the risk of disease associated with public
drinking water has passed from the theoretical to the real.” Many
illnesses that in the past could not be linked to a probable cause, can
now be directly linked to toxins in our drinking water.
The use of pesticides and herbicides has become so
excessive that they are now commonly found in household tap water with
alarming frequency.
A 1994 study of 29 major U.S. cities by the
Environmental Working Group found that all 29 cities had traces of at
least one weed killer in the drinking water. The report titled “Tap
Water Blues“ went on to say that “Millions of Americans are routinely
exposed to one or more pesticides in a single glass of tap water”.
These first ever “tap water testings” found two or
more pesticides in the drinking water of 27 of the 29 cities, three or
more in 24 cities, four or more in 21 cities, five or more in 18 cities,
six or more in 13 cities and seven or more pesticides in the tap water
of five cities. In Fort Wayne Indiana nine different pesticides were
found in a single glass of tap water!
As a startling side note it was reported that in
these 29 cities 45,000 infants drank formula mixed with tap water
containing weed killers and that “ over half of these infants were
swallowing 4 to 9 chemicals in every bottle!”
The tragic health effects of consuming these highly
toxic chemicals are magnified many times over for small children because
their systems are more sensitive and still developing. Small children
also consume a much larger volume of fluids per pound of body weight and
therefore get a bigger dose, yet non of these factors are considered
when the EPA’s maximum contaminant levels are set. The National Academy
of Sciences issued a report in 1993 on this subject and stated that “
children are not little adults, their bodies are less developed and
incapable of detoxifying certain harmful compounds.”
Another major flaw in the estimated risks of
chemicals in our drinking water is the false assumption that only that
one chemical is being consumed. The regulations are set based on what is
assumed safe for a 175 pound adult drinking water with only that one
chemical present and does not take into account the combined toxicity of
two or more chemicals. In a 1995 Science Advisory Report to the EPA it
was stated that “when two or more of these contaminants combine in
our water the potency may be increased by as much as 1000 times.”
Regardless of the differing opinions it is safe to assume that there is
no acceptable level for pesticides and weed killers in our drinking
water.
In America each year we use over 2.2 billion
pounds of pesticides, or eight pounds for every man woman and child in
the country.
Industrial solvents like TCE and Benzene make their
way into our water supplies from literally hundreds of sources. Airports
and military bases degrease planes and engine parts with TCE, one of the
most concentrated toxins in existence. One teaspoon of TCE will render
undrinkable over 250,000 gallons of water, and yet thousands of gallons
are used in uncontained applications each day. Perchlorethelyne,
cyanide, and benzene are used in such common industries as dry cleaning,
car washes and photo processing, much of which ends up going down
someone's drain and into our water supplies. It has been shown that
areas with the highest levels of these man made carcinogens in their
water supplies also have the highest incidence of cancer. Jacquelyn
Warren of the Natural Resources Defense Council commented on this
subject, “The one thing we know for sure about toxins in our drinking
water is that the more we look the more we find.”
Cancer extracts a staggering toll from our society,
one in every seven people will die from this man made disease. According
to the Center For Disease Control “Death from cancer is increasing more
rapidly than is the population” It is now widely accepted that cancer is
an environmental disease. The World Health Organization and the
National Cancer Institute both suggest that most human cancers, perhaps
as many as 90% are caused by chemical carcinogens in the environment.
This realization is paramount for change because it means that most
cancers could be prevented by minimizing or eliminating our exposure to
chemical carcinogens.
While the powerful chemical industry argues that the
levels of these toxins in the environment are not significant,
scientific evidence has shown otherwise. A National Cancer Institute
report to the Surgeon General concluded that “no level of exposure to a
chemical carcinogen should be considered toxicologically insignificant
for man.”
We spend billions of dollars each year seeking a cure
for cancer. The disease is merely a result of the real problem,
environmental pollution. If we were to direct these billions of dollars
and the same intense effort towards curing the problem (pollution)
instead of learning to live with the result (cancer) we would do future
generations a great service, and we could realistically stop the “cancer
epidemic”.
