Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

Quality of Shallow Groundwater and Drinking Water in the Mississippi Embayment-Texas Coastal Uplands Aquifer System and the Mississippi River Valley Alluvial Aquifer, South-Central United States, 1994-2004
The Mississippi embayment-Texas coastal uplands aquifer system is an important source of drinking water, providing about 724 million gallons per day to about 8.9 million people in Texas, Louisiana, Mississippi, Arkansas, Missouri, Tennessee, Kentucky, Illinois, and Alabama. The Mississippi River Valley alluvial aquifer ranks third in the Nation...Welch, Heather L.; Kingsbury, James A.; Tollett, Roland W.; Seanor, Ronald C.

Louisiana Ground-Water Map No.13: Hydrogeology and Potentiometric Surface of the Sparta Aquifer in Northern Louisiana, October 1996
This report describes the thickness and areal extent of the Sparta aquifer, identifies sands within the fresh-water extent of the aquifer, and presents data and a map that illustrate the generalized potentiometric surface (water levels) during October 1996. The report includes a detailed geophysical log, structure contour maps, hydrogeologic...Brantly, Jeffrey A.; Seanor, Ronald C.; McCoy, Kaycee L.

Louisiana ground-water map no. 6 : potentiometric surface, 1990, and water-level changes, 1974-90, of the Mississippi River alluvial aquifer in northeastern Louisiana
The Mississippi River alluvial aquifer is the largest source of fresh ground water in northeastern Louisiana. In 1990, an average of 170 million gallons per day was withdrawn from the aquifer in 12 northeast Louisiana parishes. Additional knowledge about ground-water flow and the effects of withdrawals on the Mississippi River alluvial aquifer is...Seanor, Ronald C.; Smoot, Charles W.
Louisiana ground-water map no. 8; potentiometric surface, 1991, of the Carrizo-Wilcox Aquifer in northwestern Louisiana
In northwestern Louisiana, the Carrizo-Wilcox aquifer is the primary source of ground water within six parishes (Bossier, Caddo, De Soto, Natchitoches, Red River, and Sabine) and the secondary source in parts of three other parishes (Bienville, Claiborne, and Webster). Withdrawals from the aquifer increased from 4.7 Mgal/d (million gallons per day...Seanor, Ronald C.; Smoot, Charles W.
