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 14,000people daily. An estimated 700 million Indians have no access to a

proper toilet, and 1,000 Indian children die of diarrheal sickness

every day. Some 90% of China's cities suffer from some degree of

water pollution and nearly 500 million people lack access to safe

drinking water. In addition to the acute problems of water

pollution in developing countries developed countries continue to

struggle with pollution problems as well. In the most recent

national report on water quality in the United States 45 percent ofassessed stream miles, 47 percent of assessed lake acres, and 32

percent of assessed bay and estuarine square miles were classified

as polluted.

Water is typically referred to as polluted when it is impaired by

anthropogenic contaminants and either does not support a human

use, such as drinking water, and/or undergoes a marked shift in

its ability to support its constituent biotic communities, such as

fish Natural phenomena such as volcanoes, algae blooms, storms,and earthquakes also cause major changes in water quality and

the ecological status of water.

TO EXAMINE THE PROBLEMS OF THE POND

6


7/15

1. No proper care is taken to the respective pond

2. People cannot swim or bath due to contaminated water which

contains many harmful bacteria, and viruses, which may lead to

several harmful and potential diseases.

3. Dumping of garbage such as plastic, papers and others waste

products are a serious concern to the pollution of the pond.

4. Sometimes due to improper care to this ponds leads to growth

of small weeds from the water, which leads to the blockage of the

areas of the ponds.

5. Due to this contaminated water an advantage is grown for the

mosquitoes which lay eggs and creates harmful diseases like

malaria, dengue.

CONCLUSION

The affected areas of the pond should be cleaned on a daily basis.

People living on that area should be more concerned regarding the

cleanliness of the pond, so that litters should not be dumped on thepond.

Kolkata Corporation should be informed on a monthly basis

regarding the cleanliness of the pond.

In this way the pond can be cleaned and the area of the people

will receive clean and hygienic environment from the pond.

Thus in this way if the people looks after the cleanliness of the

environment then the environment will look after us, and also it

would decrease the water pollution.
