Temporal And Spatial Variations In The Subsurface Salinity Of Lake Charles, Louisiana : An Investigation Of Saline Sources, Alexandria Suding
Temporal And Spatial Variations In The Subsurface Salinity Of Lake Charles, Louisiana : An Investigation Of Saline Sources, Alexandria Suding
LSU Master's Theses
One of the most pressing issues facing groundwater managers is saltwater intrusion. In coastal Louisiana this issue is especially prevalent. One location that is currently threated by saltwater intrusion is the industrial area of Lake Charles, Louisiana, where three high chloride areas have been detected within the underlying Chicot aquifer. Three sand units of the Chicot aquifer are present in Lake Charles: the 200-foot (200’) sand, the 500’ sand, and the 700’ sand. Groundwater with elevated chloride concentrations was first noticed by industries in the early 1970s. An initial investigation determined that the northern and southern bodies had formed by …
Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon
Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon
LSU Master's Theses
Spatial variations in salinity of pore waters in marine sediments provide useful information on processes and rates of subseafloor fluid flow and solute transport, particularly if there are evaporites in the section. Pore water salinities were determined for 18 drill holes which penetrated allochthonous salt bodies in 12 widely-scattered protraction blocks on the Louisiana offshore continental shelf and slope. Salinities were calculated from Log ASCII Standard-Logging While Drilling (LAS-LWD) logs using the Revil et al. (1998) dual-conductivity technique. The sites represent a wide range of field settings. Water depths range from 30 to 1990 m, depths to the top of …
Sources Of Salinization Of The Baton Rouge Aquifer System: Southeastern Louisiana, Callie Elizabeth Anderson
Sources Of Salinization Of The Baton Rouge Aquifer System: Southeastern Louisiana, Callie Elizabeth Anderson
LSU Master's Theses
A major environmental and economic problem confronting the Baton Rouge area, southeastern Louisiana, is the progressive salinization of the Baton Rouge aquifer system, an important source of fresh municipal and industrial groundwater. The Baton Rouge fault marks a boundary between fresh groundwaters to the north and predominately brackish waters to the south. Determining the permeability architecture of the fault is an essential component of modeling groundwater flow and saline contamination north of the fault. Understanding the sources and pathways of the saline waters that are migrating into the freshwater sands north of the fault is thus essential in helping to …
