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).

A study in an arid agricultural region of Arizona [3] showed that, even with a water level recovery of 100 ft after groundwater pumping was stopped, the land surface continued to subside for decades. This is a result of the continued dewatering of aquitards (fine-grain layers that slow the movement of groundwater) from stresses mentioned in the ...
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
Arizona’s top water authority is mulling a plan to pump water from a desalination plant by the Sea of Cortez, in a bid to lessen the state’s reliance on the Colorado River.
The tribes alleged that the pumping of water by Peabody Energy caused a severe decline in the number of springs and reduced their access to potable water. [4] Both tribes, situated in an arid semi-desert, attach religious significance to water, consider it sacred, and have cultural, religious, and practical objections to over-use of water.
Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]
Mark Wilmer Pumping Plant. The CAP delivers Colorado River water, either directly or by exchange, into central and Southern Arizona.The project was envisioned to provide water to nearly one million acres (405,000 hectares) of irrigated agricultural land areas in Maricopa, Pinal, and Pima counties, as well as municipal water for several Arizona communities, including the metropolitan areas of ...
Arizona’s Family reports that FS Residential“increased the fines to $100 monthly for June, July and August. “It’s absolutely asinine, I don’t understand,” Martin told Arizona’s Family.
