What is groundwater and why is it important?

The excess soil moisture that saturates subsurface soil or rock and migrates downward under the influence of gravity. In the literal sense, all water below the ground surface is groundwater; in hydrogeologic terms, however, the top of this saturated zone is called the water table, and the water below the water table is called groundwater. (source: Encyclopedic Dictionary of Hydrogeology; 2009)

Groundwater has many benefits to human beings. It is usually cheap to develop because it’s generally of a good quality and widespread occurrence. Being stored underground where evaporation is minimized, it is a more reliable source than surface water in times of drought.
