“…The Key Largo Limestone has an unknown thickness since the deepest core drilling on Big Pine Key reached a thickness of 52 meters without reaching the base (Hoffmeister 1974 . The result is similar to what is found in Southeast Florida and the Bahamas, with high permeability that varies laterally and with depth (Hanson 1980;Halley et al 1997;Cunningham et al 2009). …”

“…This wide variation in resistivity is related primarily to changes in porosity of limestones in the Biscayne aquifer or changes in lithology others, 2006 and2009). When freshwater is replaced by saltwater in the Biscayne aquifer, its resistivity decreases dramatically.…”

“…The Biscayne Aquifer rock that is perhaps most important and investigated in this research is characterized by 'touching-vug megaporosity', which can create stratiform, areally extensive flowpaths (Cunningham and Sukop, 2011). As discussed in the earlier works including, Parker et al (1955), Fish and Stewart (1991), and Cunningham et al (2009) water is the working fluid in both field-and laboratory-scale methods. Given previous results for non-Darcian flow in these rocks (Sukop et al, 2013), the head gradient would have to be below 10 -6 in order to obey the law described above.…”

“…The following research has provided information to better characterize the Biscayne Aquifer heterogeneity and furthermore provide an understanding of these touching-vug rock types. The formation of these megaporous rocks in the Biscayne Aquifer has been described by "eogenetic biogenic processes" (Vacher and Mylorie, 2002;Cunningham et al, 2009). The biogenic megapores observed in the Biscayne Aquifer are attributed to one or more of the following post-depositional, pre-burial (eogenetic) processes: inter-and intra-burrow megaporosity, inter-and intraroot megaporosity and fossil-moldic megaporosity.…”
