Project Summary Sheet
Fiscal Year 2003 Project Summary Report
Project Start Date: July 2002 Project End Date: September 2003
Web Sites: na
Location (Subregion): Northern half of Lake Okeechobee to southern Counties in Georgia, and from west to east coast in Florida
Funding Source: USGS's Greater Everglades Science Initiative: PBS FY 03
Principal Investigator: Nick Sepulveda
Project Personnel: Principal Investigator
Supporting Organizations: USGS (PBS)
Associated / Linked Projects: na
Overview & Objective(s): CERP's Aquifer Storage and Recovery (ASR) Project proposes to inject and then withdraw up to 1.0 billion gallons per day (Bgal/d) of surface water into and out of the Upper Floridan aquifer (UFA) during wet and dry weather conditions at selected sites near Lake Okeechobee (LO). The objective of this study is to assess the potential effects of injecting and then withdrawing 0.5 Bgal/d of water into the UFA in the northern half of LO on the potentiometric surface of the Floridan aquifer system (FAS).
Status: Locations of injection wells around the northern half of LO, used in simulations, were established. Model simulations were completed. Fluxes across model boundaries were computed, head buildups were contoured, and effects of projected 2020 withdrawals were simulated. Final figures are being generated.
Recent & Planned Products: A letter of transmittal, with simulation results, and a brief explanation of the completed work, will be sent to Ronnie_Best@usgs.gov and firstname.lastname@example.org by July 28, 2003.
Relevance to Greater Everglades Restoration Information Needs: The impact of the injection of 0.5 Bgal/d along the northern half of LO is analyzed by (1) generating a contour map of the simulated head buildups on the potentiometric surfaces of the UFA and Lower Floridan aquifer (LFA), (2) computing simulated changes in vertical leakage among the hydrogeologic units in the FAS, and (3) assessing changes in the recharge and discharge map to the UFA, all resulting from the proposed ground-water injections.
