Simulation of Groundwater Flow in the “1,500-Foot” Sand and “2,000-Foot” Sand, with Scenarios to Mitigate Saltwater Migration in the “2,000-Foot” Sand of the Baton Rouge Area, Louisiana

Charles E. Heywood, Jason M. Griffith, and John K. Lovelace Groundwater withdrawals have caused saltwater to encroach into freshwater-bearing aquifers beneath Baton Rouge, Louisiana. Groundwater investigations in the 1960s identified a freshwater-saltwater interface located at the Baton Rouge Fault, across which abrupt changes in water levels occur. Aquifers south of…
