PREFACE


 The Florida Geological Survey/Florida Department of Environmental Protection is publishing
as its Bulletin 68, the Hydrogeologic Framework of the Sinhai et Florida Water Management
District. The report summarizes a multi-year study of the three-dimensional framework of
southwestern Florida's hydrogeology, with a focus on the subsurface distribution of aquifer
systems and geologic units comprising these systems. As groundwater resources in Florida
experience increased stress due to rapid population growth, an understanding of the aquifer
systems is invaluable to environmental managers, scientists, planners and the public as decisions
are made regarding use, protection and conservation of these vulnerable resources. The FDEP-
FGS is pleased to have had the opportunity to partner with the Southwest Florida Water
Management District to complete this report.
