Confined aquifers may also be referred to as artesian aquifers.

A confined aquifer is sandwiched between confining beds (layers of impermeable materials such as clay which impede the movement of water into and out of the aquifer). Because of the confining beds, ground water in these aquifers is under high pressure. Because of the high pressure, the water level in a well will rise to a level higher than the water level at the top of the aquifer. The water level in the well is referred to as the potentiometic surface or pressure surface.
