Answer 2

The surface water is naturally purified by soils that filters the water. The correct option option is D.

What is soil water filtration?

Soil not only captures water, but it also filters it. Physical, chemical, and biological processes clean the water that flows into and through soil.

When pollutants carried by water become trapped in the small pores of the soil, they are physically cleaned.

Water is cleaned by physical, chemical, and biological processes as it passes through soil.

In addition to its physical filtration capacity, soil contains important biota that helps transform and decompose certain chemicals and other contaminants from soil, thereby aiding in the removal of these contaminants from water.

Groundwater is typically clean and safe to drink. Groundwater is usually free of microorganisms that cause disease because the soil on top acts as a filter.

Thus, the correct option is D.
