Answer:
After
independence industries are increasing in a rapid pace. The ever-increasing
number of industries has made matters worse by exerting pressure on existing
fresh water resources. Fresh water is almost limited though renewable, in India
but over-exploitation and mismanagement of this resources by industries make
the situation more grave.
(i)
Industries especially heavy industries use huge amount of fresh water for
industrial purpose. Industrial wastes pollute the resources of water, like the
waters of rivers, sea, etc.
(ii)
These heavy industries for their energy consumption purpose depend on hydroelectric
projects where electricity is generated by constructing dams on the rivers'
upstream. As a result, the river almost dries in the lower stream area.
(iii)
The contamination of water due to industrialisation makes it hazardous for
human use.
Industrial
wastes also can contaminate groundwater.
In
this way, increasing industries exert pressure on existing fresh water resources.
