|a Well logs from 67 existing deep wells in southern Florida were used to determine
the stratigraphy, depth, and extent of the Surficial Aquifer System underlying
Everglades National Park and the Big Cypress National Preserve, Florida. Four
geologic cross sections were prepared along well transects within the park and
preserve to profile the aquifer system. The profiles reveal considerable heterogeneity
in the lithologies but suggest two distinct zones: an upper zone of permeable
limestones and clastics and a more heterogeneous lower zone of relatively
impermeable fine-grained sands and sandy silts interbedded with permeable sands,
limestones, and shelly marls.
The permeable upper zone and the more permeable beds of the lower zone were
considered to be hydrologically connected; thus, the two zones were treated as
comprising a Surficial Aquifer System. Presence of a regionally continuous "green
clay bed" of the lower Tamiami Formation was verified, and it was considered the
base of the aquifer system. Depth to this bed was determined for the 67 wells, and
a contour map of depth to the base of the Surficial Aquifer System was constructed
for Dade, Collier, and northern Monroe counties. Surficial Aquifer System depths
in the study area range from 90 feet (27.4 m) to 300 feet (91.5 m) below mean sea
level.
