Groundwater Groundwater is water located beneath the ground surface in soil pore spaces and in the fractures of lithologic formations. A unit of rock or an unconsolidated deposit is called an aquifer when 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 the water table

Groundwater Groundwater is recharged from,and eventually flows to, the surface naturally;natural discharge often occurs at springs and seeps,and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal and industrial use by constructing and operating extraction wells.The study of the distribution and movement of groundwater is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

Groundwater Groundwater is hypothesized to provide lubrication that can possibly influence the movement of faults.It is likely that much of the Earth's subsurface contains some water,which may be mixed with other fluids in some instances.Groundwater may not be confined only to the Earth

Some basic concepts of Aquifers An aquifer is a layer of relatively porous substrate that contains and transmits groundwater.When water can flow directly between the surface and the saturated zone of an aquifer,the aquifer is unconfined.The deeper parts of unconfined aquifers are usually more saturated with groundwater since gravity causes water to flow downward

The upper level of this saturated layer of an unconfined aquifer is called the water table or phreatic surface.Below the water table,where generally all pore spaces are saturated with water is the phreatic zone. Ground surface Vadose Zone Capillary Fringe Water table Phreatic Zone
