Answer 1

Name and explanation: 1 Mark each

The major sources of water pollution are:
1) Increasing Population
2) Increasing Industries
3) Agricultural activities

Increasing Population: Increasing population creates demands for construction of houses, shops, offices, roads, and pavements. This decreases the open areas like parks and playgrounds. This, in turn, decreases the seepage of rainwater into the ground.

Industries: Water is used by all the industries. Almost everything that we use needs water somewhere in its production process. The number of industries is increasing continuously. Water used by most of the industries is drawn from the ground.

Agricultural Activities: Farmers have to use groundwater for irrigation. Population pressure on agriculture forces more usage of groundwater day by day. This results in depletion of water table.
