Answer:

The pesticides like DDT are sprayed on the crops to protect the crops from pests. The pesticides once sprayed, will move in a vertically downward direction in the soil and reach the various soil profiles, unsaturated zones and also reach the groundwater. This process is called Leaching.

Explanation:

The pesticides get into the soil where the plant is growing, move into the water bodies and pollute both the soil and water. Pesticides are the main source of soil and water pollution. The leaching of pesticides into the soil and water can harm the fertility of the soil, increase the rate of mortality in animals/humans consuming the water, reduce the reproductive ability of the consumers and lead to an overall reduction in species diversity.
