Explanation:
Dirty water containing chemicals is put back in the river. Water used for cooling is warmer than the river itself, and this is also a form of pollution. People are sometimes careless and throw rubbish such as bottles and crisp packets directly into rivers. ... Polluted water also carries diseases.
Answer:
River pollution is increasing day by day. In spite of various governmental projects going on in many rivers, there is no sign of water pollution being prevented or stopped. Whom do we blame? Lots of factors lead to water pollution and reducing overall quality of river water. Some of the most serious contributing factors are:
Industrial wastes, mixtures of chemicals, heavy metals are all discharged in water and these are difficult to clean up.
Agricultural wastes, chemicals, feritilisers, pesticides used in agriculture have made the river water bodies contaminated.
Nature’s rain also brings with it pollutants as it falls through polluted air. We call this acid rain, which when reached the soil, releases harmful substances.
Domestic wastes from households and the sewage that we throw into rivers increases the pollution levels.
Regular disposal of plastic bags and plastic objects, solid wastes, flowers, garlands is another cause of pollution.
People responding to nature’s call in open spaces near the water bodies also contribute to river pollution.
Animals washing, car washing, clothes washing are other causes.
Another cause of river pollution is the dumping of human remains, partially burned bodies, dead bodies, which pose serious health threats.
Surveys undertaken by the Central Pollution Control Board (CPCB) and the Centre for Science and Environment (CSE) have come up with some hard facts on river pollution, in terms of statistical figures, which makes it a matter of really serious concern:
Out of the 445 rivers surveyed, not even a quarter of them are fit for bathing.
Indian cities generate 10 billion gallons or 38 billion litres of municipal waste water every day, out of which only 29% of it is treated.
The Central Pollution Control Board also stated that there were only 160 sewerage systems and sewage treatment plants in nearly 8,000 towns surveyed in 2011.
Only 20% out of nearly 40,000 million litres of sewage produced daily in Indian cities are treated.
