Summary
The Floridan aquifer system covers nearly 100,000 square miles in the southeastern United States throughout Florida and in parts of Georgia, South Carolina, and Alabama, and is one of the most productive aquifers in the world (Miller, J.A., 1990, Ground Water Atlas of the United States-Segment 6: Alabama, Florida, Georgia, and South Carolina: U.S. Geological Survey Hydrologic Investigations Atlas HA-730-G, 28 p.). The potentiometric surface of the Upper Floridan aquifer in May 2010 was previously published in 2011, (Kinnaman, S.L., and Dixon, J.F., 2011, Potentiometric surface of the Upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama, May – June 2010: U.S. Geological Survey Scientific Investigations [...]
Summary
The Floridan aquifer system covers nearly 100,000 square miles in the southeastern United States throughout Florida and in parts of Georgia, South Carolina, and Alabama, and is one of the most productive aquifers in the world (Miller, J.A., 1990, Ground Water Atlas of the United States-Segment 6: Alabama, Florida, Georgia, and South Carolina: U.S. Geological Survey Hydrologic Investigations Atlas HA-730-G, 28 p.). The potentiometric surface of the Upper Floridan aquifer in May 2010 was previously published in 2011, (Kinnaman, S.L., and Dixon, J.F., 2011, Potentiometric surface of the Upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama, May – June 2010: U.S. Geological Survey Scientific Investigations Map 3182, 1 sheet.) and has been modified to include the area south of Lake Okeechobee in south Florida. This area of the Upper Floridan aquifer contains brackish to saline water which affects the water levels and density of the water. The water levels from the wells in this area were calculated to estimate the equivalent freshwater head and were contoured to those values. This shapefile contains the potentiometric-surface contours of the Upper Floridan aquifer for May 2010.

Groundwater contours were constructed for the Upper Floridan aquifer representing water levels from May – June 2010. This dataset was created to show the potentiometric surface contours for the Upper Floridan aquifer and to provide data to the Floridan Aquifer system ground water availability project.
