DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Raster surface generated for the 10,000 mg/L total dissolved solids boundary across the study area

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: February 10, 2026 | Last Modified: 2020-11-17T00:00:00Z
Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains a gridded surface depicting the altitude of the 10,000 mg/L total dissolved solids (TDS) boundary in reference to NGVD29. Surface is based on estimated TDS computed from geophysical logs. Where the aquifer system is fresh to base, the base of the aquifer system represents this surface.
