Water is required in large quantities in industries and in agriculture for different purposes. But care is not taken to keep the water fit for consumption. Most of the industries dump their wastes in rivers and even into the sea. Acidic water from mines and acid rain also pollute the water in rivers and seas. Power plants use large amounts of water for cooling purposes. They discharge the resultant hot water, often containing chemicals, into the water streams. This results in an increase in the temperature of water which is injurious to fish and other aquatic life forms.
