  1. Floridan Aquifer System Groundwater Availability StudyStatus September 19, 2012 Orlando

  2. FAS Study put on hold in FY 11 • Project chief left study • Eve Kuniansky Acting project chief (part time) • Team currently Lester Williams, Jason Bellino, Trey Grubbs, and Joann Dixon • Goal to complete data compilation tasks and framework • Groundwater withdrawals • Aquifer Test database • Water Levels • Springs and discharge

  3. Floridan Framework updateLester Williams-lead Stratigraphy Aquifers and Confining Units Surficial Aquifer Upper Confining Unit** Floridan Aquifer System Extent* Top of System* Upper Floridan* Middle Confining Units** Lower Floridan* Lower Confinement • Cretaceous System • Tertiary System • Paleocene Series • Eocene Series • Oligocene Series • Miocene Series • Post Miocene Will not be revised *Minor revision **Major revision

  4. Revised Hydrogeologic Framework(Lester Williams first draft at supervisory review) Major Update • Middle semi-confining units • Extent of each one • Configuration of top • Thickness of units • High T Zones • APPZ, FPZ, BZ • Location of freshwater/saltwater Interface

  5. Generalized x-section

  6. Revised Extent of Hydraulically Connected Aquifer Systems Revised extent of Floridan and Claiborne Aquifer Systems Wells in tapping Claiborne Wells tapping Floridan

  7. Saline water interface remapped (10,000 mg/L TDS) • Blue --freshwater to base • Red-- Appalachicola salinity feature • White -- contains brackish or saline in lower part of FAS

  8. Water Withdrawal Database (s) • Commercial Industrial Mining database prepared by Jason Bellino • Site specific datasets put into project database that is set up like USGS Site Specific Water Use Data System (funded in part from WaterSmart this year) in progress • Agricultural Irrigation estimates prepared by Trey Grubbs • This is estimated from a climatic water budget approach using spatial datasets of agricultural surveys and PRISM datasets– compare to Georgia metered data and other estimates as QA/QC check • In progress

  9. Rate of Decline to Relative Degree of ConfinementWater Level database prepared and analyzed Rate of decline Degree of Confinement • average rate of decline is 3 times greater in the confined areas vs. unconfined areas

  10. 2010 Potentiometric Map

  11. UFA Transmissivity map updated and database created

  12. Floridan Study Products Complete • Bellino, J.C., 2011, Digital surfaces and hydrogeologic data for the Floridan aquifer system in Florida and in parts of Georgia, Alabama, and South Carolina: U.S. Geological Survey Data Series 584. • Kinnaman, S.L., Dixon, J.F., 2011, Potentiometric Surface of the Upper Floridan Aquifer in Florida and in Parts of Georgia, South Carolina, and Alabama, May 2010: U.S. Geological Survey Scientific Investigations Map 2011-3182, 1 sheet. • Williams, L.J., and Gill, H.E., 2010, Revised hydrogeologic framework of the Floridan aquifer system in the northern coastal area of Georgia and adjacent parts of South Carolina: U.S. Geological Survey Scientific Investigations Report 2010-5158, 103 p., 3 plates. • Kinnaman, S.L., 2011, Synoptic water-level measurements of the Upper Floridan aquifer in Florida and in parts of Georgia, South Carolina, and Alabama, May-June 2010; U.S. Geological Survey Data Series Report 639. • Kuniansky, E.L. and Bellino, J.C., 2011, Tabulated Transmissivity and Storage Properties of the Floridan Aquifer System in Florida and parts of Georgia, South Carolina, and Alabama: U.S. Geological Survey Data Series 669. • Kuniansky, E.L., Bellino, J.C. and Dixon, J.F., 2011, Transmissivity of the upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama: U.S. Geological Survey Scientific Investigations Map 3204.

  13. Floridan Study Products-in review • Williams, L.J.,xxxx, Revised Hydrogeologic Framework for the Floridan Aquifer System in Florida and parts of Alabama, Georgia, and South Carolina – Professional Paper • 53 figures • 8 tables • 23 plates • 160+ double spaced pages

  14. Floridan Study Products- in progress • Grubbs, 2012, Efficiency of stratified-random sampling for estimating water withdrawals from the Floridan aquifer system • Grubbs, 2012, Estimated groundwater withdrawals from the Floridan aquifer system for agricultural irrigation • Bellino and Williams , 2012, Water Use Database and Data Compilation for Commercial, Industrial, Mining and Public Supply for the Floridan aquifer system in Florida and in parts of Alabama, Georgia, and South Carolina • Williams and Dixon, 2012, Digital Surfaces and Thicknesses of Selected Hydrogeologic Units within the Floridan Aquifer System • Williams – Digital Borehole Geophysical log database

  15. Floridan Study Products—planned for project restart FY13-15 • SIR documenting model development and calibration • PP—Groundwater Availability of the Floridan Aquifer System The restart is going to happen-currently iterating on the work plan with GW Resource Program Coordinator
