Over the years, the Louisiana Geological Survey has been involved in a wide range research concerning economic, groundwater, and environmental geology of Louisiana. For example, the Louisiana Geological Survey has conducted detailed investigations of the 1. geopressured-geothermal resources of the Gulf Coast; 2. oils and gas resources, including the Tuscaloosa Marine shale, 3.

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
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.
Across the world there’s a rapid depletion in the underground reserves of water that billions of people rely on for drinking, irrigation and other uses, new research has found.
The water is primarily a soft, sodium bicarbonate type with a dissolved-solids concentration of about 220 milligrams per liter in southern Louisiana. [1] Groundwater use in 1980 for public supply averaged 121 million gallons per day, serving over 700,000 people in southern Louisiana. In southwestern Mississippi, where the aquifer system is also ...
Scientists using seismic data tracked groundwater levels beneath the L.A. area. They found heavy rains in 2023 boosted shallow waters, but deep aquifers remain depleted.

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 ...
