aquifer

(ăk`wĭfər): see artesian wellartesian well,
deep drilled well through which water is forced upward under pressure. The water in an artesian well flows from an aquifer, which is a layer of very porous rock or sediment, usually sandstone, capable of holding and transmitting large quantities of water.

Aquifer

Any underground water-bearing rock formation or group of formations that supplies groundwater, wells, or springs.

Aquifer

 

a stratum or several strata of water-permeable rock, whose pores, cracks, or other cavities are filled with groundwater. Several aquifers hydraulically connected to each other form an aquifer complex.
