ACKNOWLEDGEMENTS This research was a cooperative effort between the Florida Department of Environmental Protection (FDEP) Florida Geological Survey (FGS) and the Southwest Florida Water Management District (SWFWMD). Special thanks are extended to David L. Moore, SWFWMD Executive Director and Dr. Walter Schmidt, FDEP-FGS Director and State Geologist for administrative and financial support. Essential geology and hydrogeology data-collection programs in the SWFWMD, FDEP-FGS and the U.S. Geological Survey (USGS) have made the development of this comprehensive report possible. Numerous individuals and countless hours of well drilling and logging, aquifer and laboratory testing, database development and management, lithologic descriptions, formation boundary determinations, surface modeling, and map/cross section production have contributed to the development of this report. The authors express their appreciation to the numerous individuals for their insightful review of the manuscript and plates. From the FDEP-FGS, these individuals include Carol Armstrong, Ken Campbell, Jackie Lloyd, Frank Rupert, Dr. Walter Schmidt, Dr. Tom Scott; from SWFWMD, Ron Basso, Michael Beach, Marty Clausen, Michael Gates, Tony Gilboy, Jason LaRoche, John Parker, Robert Peterson and Donald Thompson. Ken Campbell and Dr. Tom Scott are thanked for their contributions and discussions regarding the lithostratigraphy and hydrostratigraphy of the study area. Discussions with John J. Hickey, Rick Spechler, Dr. Tom Scott and Dr. Sam Upchurch helped refine our understanding of the hydrostratigraphy of the region. Doug Rapphun also contributed to our knowledge of the hydrogeology in the region. The authors also gratefully acknowledge those staff of the FDEP-FGS who participated in this project. Lance Johnson and Paula Polson provided assistance with cross-section development. Surface interpolations during early phases of the project were completed by Bill Pollock, Amy Graves, John Marquez and Andrew Rudin. Developers of the database for this project included Mark Groszos, Marco Cristofari and Rob Stoner. Data management support included the assistance of Jackie Bone, Patricia Casey, Lance Johnson, Natalie Sudman, and Holly Tulpin. Lithologic descriptions of numerous borehole samples were completed by Alan Baker, Jim Cichon, Erin Dom, Kris Esterson, Mabry Gaboardi, Diedre Lloyd, Matt Mayo, Sarah Ramdeen and Holly Williams. Many of the photos and photomicrographs of fossils presented in this report are provided courtesy of Roger Portell and Sean Roberts (Invertebrate Paleontology, Florida Museum of Natural History), Dr. Jonathan Bryan (Okaloosa-Walton Community College) and Frank Rupert. Dr. Rick Copeland was helpful with regard to discussions of quality assurance of hydrogeologic data and presentation of descriptive statistics.
