The main source of water pollution are as follows :-
1. Domestic Wastes :
Discharge of untreated domestic Wastes, sewage into rivers and lakes contains the chemicals present in soaps, detergents and other cleaning agents, decayed food particles. Sewage carries many kinds of diseases causing germs. It also contains many kinds of worms such as tape worms, hook worms etc.
2. Industrial wastes :
The discharge of toxic industrial wastes contains toxic chemicals such as cyanide, cadmium Mercury lead , arsenic , chromium which are highly poisonous . They make river water unfit for the use of man and aquatic plants and animals.
3. The wastewater from hospitals could contain harmful chemicals and different types of disease- causing microorganisms.
4. Agricultural wastes :
Fertilisers, pesticides and other chemicals are used for increasing agricultural productivity all over the world. These are washed away by rainwater into water sources like river. pesticides can poison fish as well as the animals ( including human ) that eat them.
To produce more food for growing human population some fungicides and Insecticides are used to kill fungi and insects, etc. For example : DDT but the increasing use is dangerous because it is non - biodegradable. Along with rain water it goes into the water.
5. Deforestation :
we are polluting water also by cutting trees and by removing vegetation. The rain water goes to small drains then to big drains, to streams and ultimately to rivers.
when top soil is covered with trees and other vegetation much of the rain water is retained by the soil and the extra water which flows into the water bodies does not contain much dirt and filth in it. But, when top soil is not covered with vegetation the rains washes away the top fertile soil which pollutes the various water bodies.
