OF TOXIC CHEMICALS
Wouldn't you think that humans would treat their limited
fresh water with respect and protect it from all contaminants? Unfortunately,
this is not so.
fresh water resources are dwindling at an alarming rate.
Increased population and water wasting are two major factors contributing
to the scarcity of this precious resource, and there are other reasons
that usable water is becoming so scarce. In some areas of the
world, pollution levels in fresh water resources are so high that the water can no longer be used even for industrial purposes.
So many toxins are being released into rivers, lakes and leaking into
groundwater resources that the water is unusable and dangerous.
Water is being poisoned by untreated sewage, chemicals, heavy metals, fuel
leakages, dumped garbage and trash, acid rain, and chemicals used in
leak into rivers and groundwater.

But, you can't
always see or smell dangerous toxins!
waters become contaminated from the dumping, burying and spilling of toxic
materials into the soil or directly into our waterways. The
destruction from toxic chemicals and waste into our waters is not just contained in the vicinity where
they were released. It spreads out into
the soil in every direction and permeates into the groundwaters which
travel far. The toxins continue downstream, bringing death, not
only to the native vegetation, but to animals that live in the water or to
those that stop by for a drink of water. And the dangerous chemical
soup that seeps into our groundwater systems endangers human lives. In those countries where the
people must rely on wells and natural systems for their drinking water,
toxic pollution of their water supplies is totally devastating and can
cause a whole area to become uninhabitable.
are destroying their own fresh water supplies which they depend upon for
TYPES OF IMPURITIES which can be
found in water, making it unsafe to drink:
Microorganisms such as algae,
bacteria, protozoa, viruses, and waste products
from living and dying organisms
Particulate matter such as clay, sand and silt
Dissolved solids and gases from man-made chemicals (such as pesticides,
herbicides, detergent residues), and rocks and minerals (such as calcium
carbonate, nitrates, phosphates, silicates, sodium chloride, sulfates and
Carbon dioxide is the main ionized gas which contaminates water.
Man-made objects, trash, garbage

OF FRESH WATER SUPPLIES CAUSING WATER CRISIS
overpumping of groundwater supplies, and massive pollution have caused a
severe water shortage in Dhaka, Bangladesh. Hundreds of tonnes of
toxic waste and harmful chemicals are dumped directly into the Buriganga river from tanneries and industries
that line its banks. (Planetark 12/13/01)
According to a
1999 study published in the Journal of Soil and Water Conservation, between
70-80 percent of all the wildlife in the western U.S. depend on stream and
riparian ecosystems. The study found that livestock grazing damaged about
80 percent of this ecosystem habitat. They eat and trample vegetation,
create sedimentation of waters, break down embankments, cause erosion, pollute
waters and watersheds, destroy habitat, cause species decline, and
drive away smaller creatures.
