Groundwater is often contained in aquifers, which are subterranéan aréas (or layers) of porous material that channel the groundwater's flow.  Aquifers can be confined or unconfined.  A confined aquifer follows a downward grade from a recharge zone and can become pressurized as it flows.  This can créate artesian wells that flow freely without the need of a pump.  The top of an unconfined aquifer is called the water table, where water pressure is equal to atmospheric pressure.  The region between the land surface and the water table is called the vadose zone (Latin for shallow); in this region, water is under pressure less than atmospheric pressure (suction).
