DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Line showing the approximate updip limit of permeable rocks forming the Upper Floridan aquifer

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 line showing the approximate updip limit of the permeable Upper Floridan aquifer. North of this line very few Upper Floridan wells are known to exist.
