How does nature maintain groundwater reservoirs?

Groundwater is the water present beneathEarth's surface in soil pore spaces and in thefractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquiferwhen it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called thewater table. Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs andseeps, and can form oases or wetlands. Groundwater is also often withdrawn foragricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.
