Chicot Aquifer System Extent in Southwestern Louisiana, October 2020 The Chicot aquifer system underlies an area of approximately 9,500 mi2 in southwestern Louisiana and is located within the Gulf Coastal Plain physiographic province. The region includes all or parts of 15 parishes -- Vernon, Rapides, Evangeline, Allen, Beauregard, Calcasieu, Jefferson Davis, Acadia, St. Landry, Lafayette, St. Martin, Cameron, Iberia, Vermilion, and St. Mary. The Chicot aquifer system is a major source of groundwater for southwestern Louisiana, accounts for approximately 48 percent of all groundwater use in the State, and provides freshwater for public supply, industry, agriculture, and aquaculture (Collier and Sargent, 2018). Withdrawals of groundwater have created water-level gradients favorable...

Reported values of interest included specific conductance, total dissolved solids, and chloride (Cl) concentration; other parameters and major/trace element concentrations were included if reported. Values listed as “NA” or “-9999” represent data that was not reported in the physical dataset. A concentration of 0 ppm or ppb represents a reported concentration of 0 and not a null value. Data were collected from scanned versions of well registration records obtained from the Louisiana Department of Natural Resources. Most well registration records may be accessed through Strategic Online Natural...
