Which one of the following statements is TRUE for an artesian aquifer?
A)The water table in the recharge area is at a higher elevation than the top of the aquifer in the subsurface.
B)In deep, stream- cut valleys, many springs are fed from artesian aquifers.
C)Upward flow from a permeable aquitard is prevented by a confining aquifer.
D)The pressure at any point in the aquifer is considerably less than the weight of the water column between the point and the top of the aquifer.

Question

Quizplus · Accepted Answer

BAn artesian aquifer is a confined aquifer containing groundwater under positive pressure. This means that the water table in the recharge area is indeed at a higher elevation than the top of the aquifer in the subsurface (A), allowing water to flow upwards when tapped by a well. Additionally, in deep, stream-cut valleys, springs fed from artesian aquifers are common (B) because the pressure can push water up through cracks and fissures to the surface.
