Control of water pollution is the demand of the day. Cooperation of the common man, social organizations, national government and non-governmental organizations, is required for controlling water pollution through different curative measures. The government should also take suitable steps for controlling water pollution by framing laws and enforcing them strictly.
Hence, the following steps should be taken for controlling water pollution:
1. Industrial and urban wastes should not be disposed of in water sources.
2. Ban may be imposed on mixing of pollutants in drinking water sources for which a boundary wall etc. may be erected around drinking water sources.
3. Domestic waste and sewage may be treated before flowing them directly in drinking water sources. Use of such treated water may be made for cooking vegetables, which may be grown on sewerage farms.
4. Bathing and washing should be banned near drinking water sources because detergents used in washing clothes pollute water. It is difficult to treat water mixed with detergents.
5. Bathing of animals near water sources should also be prohibited.
6. Use of treated filthy water should be made for irrigation because as compared to filthy water, it is more productive.
7. There are many creatures which purify water on the earth. Hence, they should be protected.
8. Chemicals and pesticides should be used in agriculture in a balanced quantity.
9. Control may be exercised on unnecessary weeds growing in water, because they affect the process of photosynthesis and pollute water.
10. Sanitary latrines may be arranged in urban areas, so that defecation in open areas is restricted.
11. People may be made aware about dangers created by water pollution so that they feel their responsibility and take steps in this direction.
12. Chlorine, potassium per-magnate and other bacteria preventing medicines may be inserted in drinking water sources from time to time so that they remain free from pollution
13. Dead bodies of humans as well as animals should not be flown in water.
The Government of India has constituted the Central Water Pollution Control Board under the Water Pollution Control and Prevention Act, 1974, which has given priority to the following facts:
1. Supervision may be kept on disposal of industrial effluents.
2. Survey may be done regarding pollution of water sources.
3. Cheap methods for treatment of polluted water may be developed.
4. Research may be done regarding environmental pollution.
5. Awareness may be generated regarding pollution.
