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 Illinois Bureau of the Budget projects that the population could increase to about 910,000 people by 2020. [ citation needed ] An estimated 100,000,000 US gallons (380,000 kL) per day of groundwater is pumped from the aquifer to supply municipal, agricultural, commercial, industrial, and rural domestic users (Larson et al., 2003).
Groundwater pumping has altered historical groundwater flow in the Sankoty aquifer. The flat geography of the area leads to groundwater flows that are perpendicular to the Illinois River; however, municipal groundwater pumping in the Peoria, Illinois area and to a lesser degree agricultural pumping elsewhere over the aquifer has led to numerous ...
On the new map, the American West stands out as particularly reliant on a network of underground water sources — like the hidden water that honeycombs the land around and to the south of Utah ...
Ages ago North America began to split roughly along the lines of the Ohio and Mississippi Rivers. Igneous rock flowed up into fissures, as a new ocean began to form. Had this continued, Illinois might have resembled the Arabian Peninsula, a broken terrain between two continents. This split, however, failed: the continent reclosed, leaving only ...
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 report, which was released Tuesday, maps areas that could floodfrom groundwater hoveringjust a few feet, or eveninches below ground. This layer of water gets pushed upward as denser water from ...
Watersheds of Illinois is a list of basins or catchment areas into which the State of Illinois can be divided based on the place to which water flows.. At the simplest level, in pre-settlement times, Illinois had two watersheds: the Mississippi River and Lake Michigan, with almost the entire State draining to the Mississippi, except for a small area within a few miles of the Lake.
