aquifer and Agriculture

The vast but relatively shallow Ogallala Aquifer lies beneath the Great Plains, under portions of eight states. Its thickness ranges from a few feet to more than a thousand feet. The Ogallala yields about 30 percent of the nation's groundwater used for irrigation in agriculture, and provides drinking water for most of the people within the area. But for many years more water has been extracted from the Ogallala than has been returned, and the situation today is of great concern.
