Floridan Framework RevisedThe hydrogeologic framework for the Floridan aquifer system has been revised throughout its extent in Florida and parts of Georgia, Alabama, and South Carolina.
Framework GIS Data AvailableDigital 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.
Water quality in the Upper Floridan aquiferReport outlines major findings of the NAWQA Program on water-quality issues of regional concern and which provides science-based information for assessing and managing the quality of our groundwater resources.
Is a Salinity Monitoring Network “Worth Its Salt”?Saltwater intrusion threatens the water supplies of many coastal communities. Management of these water supplies requires well-designed and properly maintained and operated salinity monitoring networks.
Aquifer Storage & Recovery (ASR)Aquifer Storage and Recovery (ASR) wells are part of a system to take surplus fresh surface water, treat it as required for permit compliance, and then store it in the Floridan Aquifer System (FAS) for subsequent recovery during dry periods.
The USGS Groundwater Resources Program (GWRP) is assessing groundwater availability in areas of critical importance.
