THE CURSE OF
CONTAMINATED WATER
Is there a ‘hidden,
unspoken’
problem associated with the quality of the drinking water in the U.S.?
When water quality in third world countries is discussed, no one is
surprised to
hear that the problem faced in their drinking water always surrounds
bacterial,
parasitic, and viral contaminations. Here in the United States, we
assume and/or
are told by the pundits, that our main concern deals with heavy metals
or
chemical contaminants, ie: lead, copper, nitrates. While never
diminishing the
concerns we have with regards to these issues, microbial contaminants
are by far
the greater threat, and you may find the following information alarming.
There are three basic categories
of pathogen that can be found in water. The first is protozoa
which is
the largest organism of the three categories, ranging in size from 1-16
microns.
Protozoa include the well-known Giardia Lamblia, and the
not-so-well-known
Cryptosporidium Parvum, which have been detected in 90% of U.S. surface
water.
These protozoa are more resistant to disinfection by chlorine or iodine
than
either bacteria or virus, but can be effectively filtered. The second
category
is bacteria, which are considered intermediate
sized organisms, ranging
from .2 to about 10 microns. Bacteria include such commonly-known
organisms as
Typhus, Campylobacteria, E. coli, Vibrio cholera, and Salmonella. The
third
category is viruses, which are truly tiny in size
between .02 and .085
microns. Commonly known viruses include Rotavirus, Polio, Norwalk, and
Hepatitis
A.
As per a recent report, it has
been determined that healthy people can be infected with minute
exposure to
Cryptosporidium, a small parasitic organism. In light of this report,
the
Natural Resources Defense Council
asserts that at least 45 million people
are at risk of this
diarrhea causing pathogen in what may appear as clean drinking water.
Just how
many people can really become infected from their drinking water is
impossible
to estimate. The systems who responded represent only a small
percentage of
Americans; thus, the NRDC says the figure of 45 million may be
extremely
conservative at best.
Cryptosporidium can remain viable for months
in sewage, runoff from feedlots, or groundwater until it finds a new
host. This
protozoa is neither killed by chlorine nor removed by standard filters.
Like
the very young, the elderly are at greatly increased risk from
waterborne
pathogens such as E.coli or Cryptosporidium parvum. Officials are
concerned with
the seriousness of this problem, and it has been recently said by Mr.
L.D.
McMullen, CEO of the Des Moines, Iowa, public water system and chairman
of the
National Drinking Water Advisory Council that he
envisions a future in which utilities would deliver bottled water door
to door,
like milk. Others
said physicians could write
prescriptions for bottled water!
Cryptosporidium is a very real and serious
threat to the quality of our water. According to University of Florida
researcher Joan Rose, the minimum infectious dose is low, JUST
ONE SINGLE
OOCYST! Recent data has indicated that pregnant
women, as well as
children and the immunocompromised, may be more susceptible. Finally, NO
EFFECTIVE TREATMENT has been found. In one test, after
soaking
cryptosporidium oocysts in straight household bleach for 24 hours, it
was still
able to infect mice. We may all recall the 1993 outbreak of
cryptosporidia which
swept through water-treatment filters in Milwaukee, Wisconsin. An
estimated
400,000 people became sick with varying degrees of illness including
diarrhea,
abdominal cramping, nausea, vomiting, and fever. Almost
one hundred persons died associated with this outbreak.
We do have a
problem with chemical contamination in our
drinking water; however, infectious or suspected infectious etiology
far
outweighs chemicals in water contamination. These infections have
names: Giardia
Lamblia, Shigella sonnei, Escherichia coli (E. coli), Cryptosporidium,
Fecal
Coliforms. We must remain guarded and protect our family as best as we
can.
The AquaRain Gravity Water Filter System removes waterborne pathogens
including
cysts and bacteria. These filter elements offer the tightest effective
ceramic
filtration, providing removal of pathogenic bacteria and cysts far
exceeding EPA
purifier requirements...all without having to boil your water, use
potentially
dangerous chemicals, or rely on man-made energy.
