| ABOUT WATER |
 |
| Water
is one of the most aggressive solvents known. Called the "universal solvent" water will, to a greater or lesser extent, dissolve virtually everything to
which it is exposed. |

 |
| Water
dissolves the quantity of material available until
the solution reaches saturation, the point at which
no higher level of material can be dissolved. |
|
| Impurities
found in water include atmospheric gases, minerals,
organic materials (some naturally-occurring, others
man-made) plus any materials used to transport or store
water. The hydrologic cycle (below) illustrates the
process of contamination and natural purification. |

| Contamination
in Water |
|
| There are three main groups of contamination
in water: |
|
| 1. |
Metals such
as lead, mercury, aluminium, arsenic and cadmium can, even
at very low levels, cause diseases such as cancer, brain disorders,
severe stomach disorders or even death.
The CW42® removes or controls the levels
of all these metals. |
|
|
| 2. |
Some contaminants
such as herbicides, pesticides, trihalomethanes and others
compounds caused by the reaction between chlorine and organic
matter in water are considered to be extremely harmful and
some are even carcinogenic. Many of these compounds are only
now being recognised as harmful.
The CW42® completely removes these
compounds. |
|
|
| 3. |
Bacteria, such
as E. coli and Salmonella, and parasites, such as Cryptosporidium
and Giardia, can cause severe illness or even death. Some of
these, particularly the parasites, cannot be controlled using
chlorine disinfection.
The CW42® provides complete protection
from such bacterial and protozoan pathogens. |

| Water |
|
| Water covers 70% of earth's
surface but only 0,1% is available as drinking water.
Clean and safe water is a fundamental need in society.
Two thirds of the world's population do not have water
fit for human consumption. More than 5 million children
under the age of 5 die from waterborne disease every
year. The human body made up of more than 60% water and
we need more than 3,4 litres of fresh water every day. |

Drinking
water - the essentials:
|
|
| Water must be: |
|
 |
Avaiable |
|
Free of disease |
|
Free of poison |
|
| |
| Water should be: |
|
|
Free of unpleasant
odours |
|
Free of colour
or cloudiness |
|
Free of additives |
|
Fresh tasting |
|
| |
| Water should not be: |
|
|
"Ultra" pure,
i.e. without taste and healthy minerals. |
|
| |
| The major contaminants in water
are: |
|
|
Bacteria and
cysts' |
|
Heavy metals |
|
Industrial
chemicals |
|
Agricultural chemicals |
|
| |
| The health effects from contaminated
tap water are: |
|
|
Diarrohea or
even fatal gastro-intestial disease |
|
Alzheimer's
disease/development of the brain |
|
Cancer |
|
Impaired reproductive ability |
|
| |
| Why do more and more people drink
bottled water? |
|
|
Tastes better
than tap water |
|
Movement towards
healthier living and diet |
|
Concern about artificial additivess
in soft drinks and impurities in tap water |
