DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Limestone boundary for the APPZ (Reese and Richardson, 2008)
Description
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 that shows the
northern extent of predominantly limestone forming the APPZ. North of this line the APPZ is
comprised mostly of highly permeable dolostone. South of this line the APPZ is comprised
of lower-permeability limestone.
