The Floridan aquifer system, composed of the Upper and Lower Floridan aquifers, is a sequence of Paleogene carbonate rock which spans an area of about , square miles (, km 2) in the southeastern United underlies the entire state of Florida and parts of Alabama, Georgia, Mississippi, and South Carolina.. The Floridan aquifer system is one of the world's most productive. The hydrogeology and water-quality characteristics of the Lower Floridan aquifer and the relation of the Lower Floridan aquifer to the framework of the Floridan aquifer system were evaluated during a 6-year () study. The study area, a 7, square-mile area of east-central Florida, is underlain by three principal hydrogeologic units: the surficial aquifer system, the intermediate. The hydrogeologic framework for the Floridan aquifer system has been revised throughout its extent in Florida and parts of Georgia, Alabama, and South Carolina. 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. The current understanding of the conceptual groundwater flow system (a combination of the hydrogeologic framework and how water moves into and out of the system) was developed for the FAS and adjacent systems based in part on previously published USGS Regional Aquifer-System Analysis studies (Sun and others, ), specifically many of the potentiometric maps and the modeling efforts, .
Hydrogeology and water-quality characteristics of the lower Floridan Aquifer in east-central Florida [Andrew M. O'Reilly] on *FREE* shipping on qualifying offers. Abstract. A numerical transient model of the surficial and Floridan aquifer systems in east-central Florida was developed to (1) increase the understanding of water exchanges between the surficial and the Floridan aquifer systems, (2) assess the recharge rates to the surficial aquifer system from infiltration through the unsaturated zone and (3) obtain a simulation tool that could be used by. The surficial aquifer system in Florida includes any otherwise undefined aquifers that are present at land surface. Unlike the sand and gravel aquifer and the Biscayne aquifer, which supply water to large municipalities, the surficial aquifer is mainly used for domestic, commercial, or small municipal supplies. A groundwater flow model for east-central Florida has been developed to help water-resource managers assess the impact of increased groundwater withdrawals from the Floridan aquifer system on.
