A)an unconfined aquifer that intersects the land surface.
B)a confined aquifer under sufficient pressure.
C)a confined aquifer that intersects the water table.
D)any of these

Question

Quizplus · Accepted Answer

The necessary condition to produce an artesian system is a confined aquifer under sufficient pressure. This pressure forces the water in the aquifer to rise above the surface of the ground, creating an artesian well. Option A, an unconfined aquifer that intersects the land surface, can produce a spring but not an artesian system. Option C, a confined aquifer that intersects the water table, does not necessarily produce an artesian system as the water needs to be under sufficient pressure to rise above the ground. Therefore, the correct answer is B.
