water pollution

Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. An estimated 700 million indian's have no access to a proper toilet, and 1,000 Indian children die of diarrheal sickness every day.

Water is typically referred to as polluted when it is impaired by anotherpogenic contaminants and either does not support a human use, such as drinkingwater, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as algae blooms, and earthquakes also cause major changes in water quality and the ecological status of water.
