Located in Texas, USA, the Edwards Aquifer is a major source of water for central and southern Texas. The aquifer is a massive underground layer of porous limestone that stores and transmits water. The aquifer is recharged by rainfall and surface water from the Edwards Plateau and can be accessed through wells and springs. The water from the Edwards Aquifer is used for drinking, irrigation, and industrial purposes, supplying up to 2 million people with water on a daily basis.
