Water Pollution is the introduction of contaminants into the water body that disturbs aquatic environment. Water pollution affects the entire biosphere plants and organisms living in these bodies of water. Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels.
There are several classes of water pollutants. The first are disease-causing agents. These are bacteria, viruses, protozoa and parasitic worms that enter sewage systems and untreated waste. A second category of water pollutants is oxygen-demanding wastes; wastes that can be decomposed by oxygen-requiring bacteria. When large populations of decomposing bacteria are converting these wastes it can deplete oxygen levels in the water.
