Answer:
The Ogallala Aquifer has a shallow water table and is mostly surrounded by sand particles, silt and clay, and some gravels that are present below the Great Plains in the United States.
It contains about 3 billion acres feet of water but still, it could run dry. it has a total water storage that is equivalent to the Huron Lake that is located in the Midwest.
It is the only source of water within the regions of high plain areas that actually provides the water for residential, industrial, and agricultural use.
This groundwater is already contaminated and slowly getting declined, as a result of which the water in this aquifer will slowly become extinct or unsuitable for any purposes.
