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 …
