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.
Englishtown aquifer; Floridan aquifer; Great Miami aquifer; Kirkwood–Cohansey aquifer; Lloyd aquifer; Magothy aquifer – largest of Long Island's aquifers; Mahomet Aquifer; Medina aquifer; Mt. Laurel–Wenonah aquifer; Ogallala Aquifer, also known as the High Plains Aquifer; Ozark Plateau aquifer; Patapsco aquifer; Permian Sea; Potomac ...
The Floridan aquifer system is composed of two main aquifers: the Upper Floridan aquifer and the Lower Floridan aquifer. These aquifers are separated by sediments that range from low-permeability clays in the panhandle (Bucatunna Clay) and low-permeability dolomites and gypsiferous anhydrite in west-central Florida to permeable limestones along ...
The 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 ...
The Biscayne Aquifer, named after Biscayne Bay, is a surficial aquifer. It is a shallow layer of highly permeable limestone under a portion of South Florida . The area it underlies includes Broward County , Miami-Dade County , Monroe County , and Palm Beach County , a total of about 4,000 square miles (10,000 km 2 ).
In 1940, Parker began his career as a hydrogeologist when he made a cross-country trip to help save the water supply of Miami, Florida from saltwater intrusion.Parker developed protective measures to save well fields and also from 1940 to 1947 identified and named the Biscayne Aquifer, the Floridan Aquifer and defined the geologic structure of southern Florida.
The Great Miami River (also called the Miami River) (Shawnee: Msimiyamithiipi [2]) is a tributary of the Ohio River, approximately 160 miles (260 km) long, [3] in southwestern Ohio and Indiana in the United States. The Great Miami originates at the man-made Indian Lake and flows south through the cities of Sidney, Piqua, Troy, Dayton ...
In the aquifer, groundwater flows from points of higher pressure to points of lower pressure, and the direction of groundwater flow typically has both a horizontal and a vertical component. The slope of the water table is known as the “hydraulic gradient”, which depends on the rate at which water is added to and removed from the aquifer and ...
