Learn about a 60-year U.S. Geological Survey study examining saltwater intrusion in the Floridan aquifer system near Brunswick, Georgia in this conference presentation. Explore how saltwater was first detected in the Upper Floridan aquifer wells in 1957 and track its northward migration toward industrial pumping centers. Examine data from a deep test well that identified the saltwater source in the Fernandina permeable zone of the Lower Floridan aquifer. Review recent findings from 2020 water-level measurements and chloride concentration sampling that show the stability of the chloride plume over 15 years, while vertical hydraulic-head gradients indicate ongoing upward saltwater migration. Understand how local pumping influences groundwater flow patterns in the downtown Brunswick area through detailed potentiometric-surface mapping of the Upper Floridan aquifer.
