Question

In towns and cities, generally, bore wells have to be dug very deep to get water as compared to bore wells dug in villages. Give suitable reasons

Answer 1

• In cities and towns, the ground surface is covered with concrete hence rainwater cannot percolate deep into the ground.​

• This results in the decrease in groundwater levels, as groundwater cannot be refilled easily.​

• In villages most of the ground surface consists of soil and less concrete constructions.​

• Thus, bore wells do not have to be dug as deep as that required in cities.
