“…In the southern part of the peninsula, it is likely that the surficial quartz sand unit was once a mixture of quartz sand and skeletal carbonates, similar to sediments currently being deposited on the barrier islands and beaches, and associated subtidal marine environments of southwestern and southeastern Florida (Missimer ). The sediments underlying the sand mantle in southern Florida occur within the Fort Thompson, Caloosahatchee, Miami Limestone (parts), Anastasia, Tamiami, and Peace River formations, which are all mixtures of siliciclastic (predominantly quartz sand) and skeletal carbonate grains, most of which were originally composed of aragonite (Parker and Cooke ; Puri and Vernon ; Peck et al ; Boggess et al ; Missimer , , Causaras , , Fish ; Fish and Stewart ; Missimer et al ). The shell material within the modern beaches of southwest Florida are dominated primarily by the genera Anadara , Noeta , Donax , Chione , Arca , gastropods, and others that have solely aragonitic shell as determined by X‐ray diffraction (Missimer ; Carter ).…”

Mixed carbonate and siliciclastic marine sediments commonly become freshwater aquifers in eastern coastal regions of the United States and many other global locations. As these deposits age, the carbonate fraction of the sediment is commonly removed by dissolution and the aquifer can become a solely siliciclastic system or contain zones or beds of pure quartz sand. During aquifer evolution, the sediment grain size characteristics, hydraulic conductivity, and porosity change. An investigation of these changes using mixed carbonate/siliciclastic sediment samples collected from a modern barrier island beach in southern Florida showed that the average mean grain diameter decreased with removal of the carbonate fraction, but the average hydraulic conductivity and porosity increased slightly, but not to statistical significance. This counterintuitive result occurs because of the change in the pore types from a combined shelter and intergranular pore system producing a dual porosity system in the mixed sediments to a single intergranular pore system in the siliciclastic sediment fraction. Within the mixed carbonate/siliciclastic sediment, in the pure carbonate fraction, large shell fractions form grain-supported large pores, which become filled with sand-sized quartz as the shell fragments decrease in size or as the sediment becomes compacted. The hydraulic conductivity increases because the shell fragments that were oriented perpendicular to flow caused an increase in the length of the flow path, or a larger scale tortuosity, compared with the flow through pure quartz sand.

The population of Collier and Lee Counties in southwestern Florida has increased 11‐fold from 1960 to 2004 with a concomitant increase in freshwater demand. Water levels and salinity within the water table aquifer over the past two to three decades have generally been stable, with more monitoring wells showing statistically significant temporal increases in water level than decreases. Residential development has had a neutral impact on the water table aquifer because the total annual evapotranspiration of residential communities is comparable to that of native vegetation and less than that of most agricultural land uses. Public water supply systems and private wells also result in net recharge to the water table aquifer with water produced from deeper aquifers. Confined freshwater aquifers have overall trends of decreasing water levels. However, with the exception of the mid‐Hawthorn aquifer, water levels in most areas recover to near background levels each summer wet season. Freshwater resources in humid subtropical areas, such as southwestern Florida, are relatively robust because of the great aquifer recharge potential from the excess of rainfall over ET during the wet season. Proper management can result in sustainable water resources.

“…These two aquifers are separated by a section of sediments of low permeability that retards circulation of ground water between the permeable units. Detailed hydrogeologic descriptions of the surficial aquifer system are presented by Boggess (1981), Boggess and Watkins (1986), Smith and Adams (1988), and La Rose (1990).…”

Direct-current electrical resistivity data were collected from 109 vertical electrical sounding sites in Hendry and Collier Counties, southwestern Florida. Selected direct-current electrical resistivity surveys, together with available borehole geologic and geophysical data, were used to determine the approximate areal extent of the shallow clastic aquifers composed of thick sands and carbonate lithologies. Results indicated that a complex pattern of shallow sands, clays, and carbonate lithologies occur throughout the area. Buried channel sands were found as deep as 50 meters below land surface in some places. The channels contain unconsolidated fine-to mediumgrained quartz sand interbedded with sandy limestone, shell fragments, and gray-green sandy clay. Purpose and Scope The purpose of this report is to assess the hydrogeologic characteristics and relations of shallow aquifers in southwestern Florida using direct-current (DC) electrical resistivity, borehole geophysics, and lithologic data. Three geohydrologic and four geoelectric sections were constructed using selected direct-current electrical resistivity sounding sites, one test hole,
