The groundwater is being discharged faster than it is being recharged is the data suggested.
Option D
<h3><u>Ex
planation:</u></h3>
Ground water level is the level of underground storage of water above the impermeable rock layer. The underground water is getting filtered through different layers of permeable rocks before it enters the final layer. So it’s fresh and ready to be consumed as it is taken out. Thus for centuries, it’s being used as the source of drinking water.
But with increasing population, the ground water is being consumed at the rate very faster than it can be refilled from different sources like precipitation, rivers and other water bodies. So its level tends to get lower and lower as this continues until the point it gets finished.

DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.
