DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Extent of the FPZ region of the Oldsmar permeable zone
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 polygon showing the extent of the Fernandina permeable zone in northeastern Florida and southeastern Georgia. From Miller, 1986
