HOW WATER BECOMES POLLUTED
If water, as it occurs in nature, were “pure” water, there would be no need [or water
testing or water treatment. But, unfortunately, whatever the source, water contains
impurities in solution or in suspension.
As rainwater descends through the air, oxygen, nitrogen, and carbon dioxide are
dissolved in the falling water. It also encounters dust, smoke, and other impurities which
are dissolved or retained in suspension. Bacteria and the spores of microscopic
organisms may also be picked up. Rainwater, in descending through the air and in
percolating through the upper layers of the soil, absorbs carbon dioxide which combines
with water so that it dissolves a certain amount of the mineral matter of the soil or rocks : 3
which it comes in contact.
Water obtained from the surface streams may be rendered turbid by the presence of clay
or silt. Agricultural land may contribute to the organic matter and may pollute the water
with animal wastes. Swamps may discharge their waters during floods and carry
decayed vegetable matter, color, and microscopic organisms into the stream. In addition,
surface water is exposed to pollution by animals, humans, cily sewage and the wastes of
industries.
The water obtained from deep wells usually contains relatively high concentrations of
dissolved minerals, metals, or salts. These waters are normally clear and colorless,
however chemical impurities are present in all natural waters and a water test is 8
essential to find the maximum amounts of these impurities which may be tolerated. :
With all the talk these days about water pollution, more and more people have begun to
take a hard look at the quality of water coming into their homes, not only lor drinking
and cooking but also for bathing and washing.
Quality water is no longer a matter of chance;
it is a question of choice.
The decision ... and control ... is in your hands.
