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 ...
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 ...
On August 31, flood levels started to subside. The water level in the city had reached that of Lake Pontchartrain, and as the lake started to drain back into the Gulf, some water in the city started to flow into the lake via the same levee breaches they had entered through. In 19th century lake floods, the water soon flowed back into the lake ...
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.
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

Static level is the level of water in the well when no water is being removed from the well by pumping. [8] Water table is the upper level of the zone of saturation, an underground surface in which the soil or rock is permanently saturated with water. [9] Well yield is the volume of water per unit time that is produced by the well from pumping. [8]
