Update on Efforts to Address Saltwater Intrusion in the Capital Area

Anthony J. Duplechin

Due to heavy pumping of certain aquifers within the Capital area, saltwater from the south has moved across the Baton Rouge Fault into some of the fresh water aquifers in East Baton Rouge Parish. The Capital Area Groundwater Conservation District is empowered to take all necessary steps to prevent intrusion of salt water or any other form of pollutant into any aquifer or aquifers, including the powers to operate withdrawal wells for the extraction of salt water or water affected by any pollutant and to dispose of such water by injection or otherwise; to operate injection wells to create freshwater barriers against salt water intrusion or the intrusion of any other pollutant; and to control pumping rates by users in any area threatened by intrusion of salt water or other form of pollutant. The District is currently exploring its options to address saltwater intrusion in the “2,000-ft” sand.
