The Health Effects Of Drinking Water Contamination
U.S.
drinking water contains more than 2100 toxic chemicals that can
cause cancer. -
Ralph Nader Research
Institute The causes of
tap water contamination are many, ranging from agricultural
runoff to improper use of household chemicals and everything in
between. Few of us realize the extent or impact of these low
level synthetic chemicals in the water we use. While the standard
use in our society of over 80‚000 different synthetic chemicals
has offered added convenience and productivity in our lives‚ it
has also come at a tremendous price... drastic increases in
degenerative disease.
In the early 1900s‚ before
chlorine‚ pesticides‚ herbicides and the tens of thousands of
other chemicals that we are exposed to every day‚ the average
American had a 1 in 50 chance of getting cancer‚ today 1 in 3 can
expect to get cancer in their lifetime‚ 1 in every 2 males.
Our use of man-made chemicals has
become so extreme that we can now find traces of these low level
SOCs (synthetic organic chemicals) in virtually every public
water supply around the world. A recent report by the Ralph Nader
Study Group‚ after reviewing over 10‚000 documents acquired
through the Freedom Of Information Act‚ confirmed that "U.S.
drinking water contains more than 2100 toxic chemicals that can
cause cancer."
We've learned that any chemical we
use in our society, will eventually wind up in our water
supplies. There is no "new" water! Our planet re-uses the same
water over and over. And as our use of SOCs increases, so does
the toxicity of our water. Earth's natural filtration process is
not effective at removing these toxic SOCs... nor is municipal
water treatment. Industry, agriculture and individuals... all
contribute to the problem. Many of the contaminants found in
water can be traced back to improper or excessive use of ordinary
compounds like lawn chemicals‚ gasoline, drycleaning solvents and
cleaning products.
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 vunerable our
water supplies really are.
Our municipal water treatment
facilities do not remove SOCs 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, filter out the visable particles and add bleach!
"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 Chief.
One of America‘s leading
authorities on water contamination‚ Dr. David Ozonoff of the
Boston University Of Public Health states‚ "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 have now been linked to
toxins in our drinking water.
"While levels of these carcenogens (SOCs) in drinking
water are low, it is precisely these low levels that
carcenogenists belive to be responsible for the majority of human
cancers in the U.S."
U.S. Council On Environmental Quality
The use of pesticides and herbicides
has become so excessive that they are now commonly found in
household tap water and bottled water with
alarming frequency.
A 1998 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 "Weed Killers By The Glass" 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 5 major U.S.
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 none 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
"children are not little adults" and their bodies
are less developed and simply 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 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!"
It has been shown that areas with
the highest levels of these SOCs 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."
