WATER TEST INFORMATION
2-2.
GENERAL.
The purpose of this section is to provide information
which will be useful to the operator who has limited training or
experience in water testing.
A brief review of some of the needs for
and some of the properties of water which necessitate water testing
are as follows:
a. Water.
An adequate water supply is a matter of life or death
for troops,
or other human beings in the field.
Man might survive for
months without food but would die in about a week without drinkable
water.
Water makes up approximately 60% of a man’s weight, or on the
average about 47 liters (50 quarts).
Every day, man must replenish
about 2.37 liters (2.5 quarts) of it.
Water is essential for blood
circulation,
waste removal and muscle movements.
As a substance water
is odorless,
tasteless and colorless.
As a chemcial, it is a weak
acid and remarkable solvent.
It draws away from most organic (carbon
compounds) substances but is strongly attracted toward the absorption
of inorganic substances.
Water is so benign that many forms of life
can thrive within it - and so corrosive that, given time, it will
