Meeting today's food production demand in the 21st century in the United States will depend on ground-water. U.S. agriculture uses 49.5 billion gallons of groundwater per day, on average, for irrigation-65% of the nation's daily total of 76 billion gallons. Sustaining the nation's ground...
G) The Ogallala Aquifer is a vast, shallow underground water table aquifer located beneath the Great Plains in the United States. One of the world’s largest aquifers, it covers an area of approximately 174,000m2(450,000km2) in portions of eight states: (South Dakota, Nebraska, Wyoming, ...
Analysis of about 170,000 monitoring wells and 1,693 aquifer systems worldwide shows that extensive and often accelerating groundwater declines are widespread in the twenty-first century, but that groundwater levels are recovering in some cases. Scott Jasechko Hansjörg Seybold James W. Kirchner ...

Depletion of the Ogallala Aquifer1. [4] This is a FactualInformation question asking for specific information that can be found inparagraph 1. The correct answer is choice 4. Sentence 2 in the paragraphindicates that there was “low-intensity” farming and ranching in the HighPlains region for...
Presently, groundwater in the United States is withdrawn approximately four times faster than it is naturally replaced. The Ogallala Aquifer, a huge underground reservoir stretching under eight states of the Great Plains, is drawn down at rates exceeding 100 times the replacement rate. Agricultural ...
Florida’s booming population is writing a water check its aquifers can’t cash; from lawn sprinklers to kitchen faucets, Florida needs to cut back and use less water.
In 2007, virtual groundwater transfers from the High Plains, Mississippi Embayment, and Central Valley aquifer systems totaled 17.93 km3, 9.18 km3, and 6.81 km3, respectively, which is comparable to the capacity of Lake Mead (35.7 km3), the largest surface reservoir in the United States. ...
Irrigation over the Ogallala Aquifer in the central United States increased dramatically over the 20th century and has enhanced regional precipitation49. The precipitation increase in the Texas Panhandle from 1952 to 1980 was obviously due to the increase in the irrigation area25. On the other hand...
Depletion of the Ogallala Aquifer The vast grasslands of the High Plains in the central United States were settled by farmers and ranchers in the 1880’s. This region has a semiarid climate, and for 50 years after its settlement, it supported a low-intensity agricultural economy of cattle ran...
