Aquifers of the United States Withdrawal rates from the Ogallala Aquifer.. This is a list of some aquifers in the United States.. Map of major US aquifers by rock type. An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

The groundwater supply across the country is depleting at an alarming rate. A new study found that groundwater supplies around the world are depleting faster than they were 40 years ago.
Many states, especially in the western United States, claim ownership of groundwater and allocate the resource through an appropriative system just as they would any surface right. Typically water rights are appropriated based on each aquifer's sustainable yield, and once all the rights are granted no further permits will be issued. Some states ...
