The following is a partial list of aquifers around the world. ... Magothy aquifer – largest of Long Island's aquifers; Mahomet Aquifer; Medina aquifer;
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.
In sequence from shallowest to the deepest, the Long Island aquifers are: the Upper Glacial, the Magothy and the Lloyd Aquifers. All Long Island aquifers receive their fresh water from precipitation which takes from 25 to 1,000 years to migrate through the layers to the aquifers, which hold roughly 70 trillion US gallons (260 km 3)—enough to ...
The Illinois side includes Henry County, Mercer County, and Rock Island County. [4] In extreme northwestern Illinois the Driftless Zone, a region of unglaciated and therefore higher and more rugged topography, occupies a small part of the state. Charles Mound, located in this region, is the state's highest elevation above sea level.
Most of the sand and gravel of the Mahomet Aquifer is from the lower half of the Banner Formation and belongs to the Mahomet Sand Member which is buried 100 to 200 feet (30 to 61 m) below the ground surface. The aquifer underlies 1,260,000 acres (510,000 hectares) of land in east-central Illinois and spans 15 counties (Panno and Korab, 2000).
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.
Illinois' ecology is in a land area of 56,400 square miles (146,000 km 2); the state is 385 miles (620 km) long and 218 miles (351 km) wide and is located between latitude: 36.9540° to 42.4951° N, and longitude: 87.3840° to 91.4244° W, [1] with primarily a humid continental climate.
Long Island drinking water is sourced from a large aquifer which is at risk of contamination if chemical pollution continues. Long Island is one of the most developed areas in the United States with a majority of the high intensity development located closer to New York City and lower intensity development moving east across the island. High ...
