Which of the following is a common setting for a spring?

A) a limestone aquifer that intersects the surface
B) a permeable upper layer with a water table deep below the surface
C) a nonpermeable upper layer with a water table deep below the surface
D) an unconfined aquifer with a water table deep below the surface

Limestone Aquifer

An underground layer of water-bearing permeable rock, typically limestone, which can store and yield significant quantities of groundwater.

Permeable

Characteristic of a material that allows fluids or gases to pass through it due to the presence of interconnected pores or spaces.

Nonpermeable

Materials that do not allow fluids to pass through them, preventing the movement of water or other substances.
