Aquifer

Shelby County is located over four natural aquifers, one of which is recognized as the "Memphis sand aquifer" or simply as the "Memphis aquifer". This artesian water is pure and soft. This particular water source, located some 350 to 1,100 feet (110 to 340 m) underground, is estimated by Memphis Light, Gas and Water to contain more than 100 trillion US gallons (380 km3) of water.
