Delineation of the Freshwater-Saltwater Interface at Selected Public-Supply Wells Using Advanced Surface and Borehole Geophysical Techniques, in Eastern Suffolk County, New York

The combination of a complex hydrogeologic framework, narrow land masses surrounded by saltwater, and extensive ground-water public-supply pumpage has produced localized areas of elevated chloride concentrations in ground water. This project uses advanced surface and borehole geophysical methods to determine the extent of saltwater intrusion and road-salt plumes at selected sites in eastern Suffolk County, Long Island, NY. Two-dimensional resistivity sections have been integrated with borehole geophysical logs and water-quality data to produce cross-sections of road-salt plumes. Borehole geophysical logs are collected twice a year to determine variations in chloride concentration and thicknesses of intrusive...
