whole humanity. Nothing will be able to live without water. However, we do not appreciate this gift of nature and pollute it without thinking Drinking water. quality is poorly managed and monitored. The key causes of the water pollution are: industrial waste, mining activities, sewage and waste water, accidental oil leakage, chemical pesticides and fertilizers. burning of fossil fuels, animal waste, urban development, global warming, radioactive waste, and leakage from sewer lines. There is less water available for drinking. cooking. irrigating crops, and washing.
Types of Water Pollution:
On the basis of sources of water, water pollution can be divided into the following categories:
1. Ground water pollution;
2. River water pollution;
3. Lake water pollution; and
4. Sea water pollution.

Water is the most important constituent of the life support system because on one hand it is vital for the maintenance of all forms of life and on the other it helps in the movement, circulation and cycling of nutrients in the biosphere. Water is essential for power generation, navigation, irrigation of crops, disposal of sewage etc.
It may be noted that only one per cent of the total quantity of water of the hydrosphere is available to human beings and other biotic communities from various sources such as ground water, rivers, lakes, atmosphere and biological systems.
Coupled with population explosion, rapid industrialisation and unplanned urbanisation, are releasing a lot “of waste into water bodies thereby degrading the quality of water. Though water like other natural substances has self purifying capacity during recycling processes but when the foreign undesirable substances added to it exceed the tolerance level and self-purifying capacity of water, it gets polluted.
Thus water pollution may be defined as deterioration of physical, chemical and biological characteristics of water through natural and anthropogenic activities to such an extent that it becomes harmful to human beings, plants and animal communities. According to United States Public Health Services, water pollution means “the presence of any toxic substance in water that degrades the quality to constitute a hazard or impair its usefulness.
Water pollution may also be described as extraneous enrichment of chemicals which alter the physico-chemical environment changing the community composition and compelling some species or many species to disappear from the natural eco-system. The results of water pollution are evident whether measured by harms to the living resources or hazards to human health or reduction of immunities.
Anyway, water pollution is a global problem affecting both developed and developing countries. Human activities related with water pollution comprised mining, agriculture, stockbreeding, fisheries, urban human activities, various industries, such as manufacturing industry, domestic sewage etc.

Essay Water Pollution
Water pollution refers to any physical or chemical change in water, which could adversely affect its use for domestic, irrigation, industrial and recreational purpose or adversely affect the aquatic biota or any living organism.
Causes and Sources of Water Pollution:
The pollution of water may occur due to aquatic contaminants between two extremes:
(1) A body of water poisoned by toxic chemicals which may eliminate many living organisms or even exclude all forms of life.
(2) An over productive river or lake enriched with nutrients from sewage or fertilizer.
Like air pollutants, water pollutants come from a number of natural and man-made sources.
Broadly, these sources may be classified into two categories:
(i) Point sources: These sources emit pollutants at discrete locations, usually a pipe that leads to a stream or a lake, e.g., factories, power plants and sewage treatment plants. They are easier to control because the source is located at specific places.
(ii) Non-point sources: These sources emit general watershed run-off which is diffused and scattered, e.g., cropland, forests, urban and suburban lands, and roadways. Non-point water pollutants are generally more difficult to control because it is difficult to trace the various site of discharge.

Farming activities use a lot of pesticides and insecticides made of harmful chemicals. During rains these chemicals get washed and enter water streams and
finally into larger waterbodies. Sewage from our residences is let out into water bodies which causes water pollution
Sea and ocean water often gets polluted due to oil.spillage done by oil carrying ships. Natural elements like floods and earthquake also Cause contamination of water causing water pollution
The time has come to strictly enforce the water pollution laws and develop a mechanism for the proper disposal of waste and fight water pollution. The unified action of government and society is required to curb out the issue of water pollution.
Let’s take our step forward in making clean water availability as the birth right of every

There are many chemnicals that are naturally found in these bodies of water Today water may be polluted by nitrates, phosphates, oil, acid rain, and debris such as sediment, fallen logs and so on.When people and animals drink water from such rivers, the poisonous chemicals may affect them.
