Aquifers of the United StatesWithdrawal rates from the Ogallala Aquifer.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.[1]
Ogallala Aquifer of the central United States is one of the world's great aquifers, but in places it is being rapidly depleted by growing municipal use, and continuing agricultural use. This huge aquifer, which underlies portions of eight states, contains primarily fossil water from the time of the last glaciation. Annual recharge, in the more arid parts of the aquifer, is estimated to total only about 10 percent of annual withdrawals.
Floridan Aquifer underlies the entire state of Florida as well as southern portions of Alabama, Georgia and South Carolina, and covers an area of 100,000 square miles. It developed millions of years ago during the late Paleocene to early Miocene periods, when Florida was underwater, and is one of the world's most productive aquifers.
Edwards Aquifer in Texas is important as a water supply aquifer and the source of major springs. This carbonate aquifer has historically been providing high quality water for nearly 2 million people, and even today, is completely full because of tremendous recharge from a number of area streams, rivers and lakes. The primary risk to this resource is human development over the recharge areas.
Basin and Range Carbonate Aquifer, and known by many names, is an important and unique aquifer in that it covers several western states and basins. Groundwater flows through fractured carbonate rock beneath basins and leads to many regional springs and water features, like Fish Springs National Wildlife Refuge and the springs at Death Valley. This has been studied in extensive projects like the USGS BARCASS report[2] and is controversial due to water issues like that in Snake Valley, Utah.
Snake River Aquifer Located in Southern Idaho this aquifer stretches almost to Yellowstone National Park on its Eastern edge all the way to Hell's Canyon along the Idaho Oregon border on the Western edge. Water from the aquifer is used to irrigate over 3 million acres of farmland in Southern Idaho as well as provide drinking water for many Southern Idaho communities.[3]
Mahomet Aquifer supplies water to some 800,000 people in central Illinois and contains approximately four trillion US gallons (15 km3) of water. The Mahomet Aquifer Consortium[4] was formed in 1998 to study the aquifer with hopes of ensuring the water supply and reducing potential user conflicts.
Central Valley Basin of California, where originates a vast amount of US crops for both domestic consumption and export. An estimated 2,700 cubic kilometers of accessible "fresh" water remain when deep well sources included in the eight counties of the study, some of which may be polluted by oil activities, some of which may be briny, nevertheless it is larger than the 900–1000 cubic kilometers thought to have been present. In spite of apparent windfall, ground subsidence, unregulated drilling, water-hungry high-profit agriculture and prolonged drought remain major obstacles to sustainability.[7] Over a hundred cubic kilometers are thought to have been permanently lost (compacted clays cannot reabsorb) since farming took off in the valley a century ago, some 10 cubic kilometers were being lost annually both years of 2012–2013 according to GRACE satellite measurements.[8]
