What are groundwater tables?
The water table is an underground boundary between the soil surface and the area where groundwater saturates spaces between sediments and cracks in rock. Water pressure and atmospheric pressure are equal at this boundary.
Which is the top layer of groundwater?
The top of the saturated zone is called the water table (Diagram 1). The water table may be just below or hundreds of feet below the land surface.

How big is a water table?
Although the water table varies throughout the Oglalla Aquifer, it is generally 15 to 90 meters (50 to 300 feet) below the land surface. Industrial agriculture and development in the 1940s and 1950s contributed to lowering the water table by more than a meter (3.5 feet) year.
Where can I find underground water for Borewell?
