Ogallala Aquifer

All water that is below Earth s surface is called groundwater. (Liquid water that is on the surface—in streams, rivers, and lakes—is called, naturally enough, surface water.) Any water-bearing soil layer is called an aquifer, which can be thought of as an underground water reservoir. Aquifers underlie the land in many places and collectively contain an enormous amount of fresh water— approximately 35 times the total volume of water in fresh water lakes, rivers, and streams combined. More than half the land area of the United States is underlain by aquifers, such as the Ogallala Aquifer stretching from South Dakota to Texas and from Colorado to Arkansas ...

Aquifers are underground bodies of water which, in the best instances, are as pure as rain water. Some of them are huge in extent (e.g., the Ogallala aquifer lies under part of Texas and several other states). They are a prime source of water for irrigation.
