Ground water is the water that seeps through rocks and soil and is stored below the ground. The rocks in which ground water is stored are called aquifers. Aquifers are typically made up of gravel, sand, sandstone or limestone. The area where water fills the aquifer is called the saturated zone. The depth from the surface at which ground water is found is called the water table.
The underground (hydrogeological) setting of ground water defines the potential of this resource and its vulnerability to irreversible degradation. This setting in India can be divided into following categories, which are described below:
