Groundwater - Wikipedia

Groundwater, is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock 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.
