A farmer is analyzing cross sections of his land to determine where to build a well. Which phrase describes the best area to dig down to the groundwater?
A: where the saturated zone is 15 meters deep
B: where the water table is at 100 meters deep
C: where the unsaturated zone is 50 meters thick
D: where there is a 25-meter thick clay layer at the surface

If the saturated zone is 15 meters deep, that area is the best to dig down so its A.

Explanation:

The saturated zone is the area under the ground where the water is stored in tiny spaces between rock, soil, sand, and gravel.

The water in this region flows freely through the pores within the geologic medium.

Most people dig a hole to insert pipes until this region identified with water for the purpose of boring and building wells.

These regions can be found after digging above hundred feet or just below the ground surface.
