Question

In a village, the local pond is usually used by villagers for all their requirements of water. Make a list of at least five activities of the villagers which might pollute the pond and make the water unfit to drink.

Answer 1

Five activities of the villagers that might pollute the pond are as follows:

• People take bath in the pond and release organic matter into it. This gets accumulated in the pond.
• People wash their clothes and utensils and pollute the pond.
• People living on the side of the pond usually lay their latrines on its banks.
• Villagers allow their cattle to take bath in the pond, making its water unfit to drink.
• Fertilisers and pesticides are also sources of pollution. In many farms, chemicals are sprayed on crops to help them grow and prevent from pests. When it rains, the extra fertilisers and pesticides flow into the streams and causes pollution of water bodies.
