Evaluation Of Fresh-Water Resources At The Line Hole Wellfield Using Electrical Resistivity Tomography, Scot A. Russell, Lee J. Florea, Chasity L. Stinson
Evaluation Of Fresh-Water Resources At The Line Hole Wellfield Using Electrical Resistivity Tomography, Scot A. Russell, Lee J. Florea, Chasity L. Stinson
Lee J Florea, PhD, P.G.
A major economic constraint in the Bahamas, and other small carbonates islands world-wide, is the lack of fresh water resources. To better address socio-economic problems on San Salvador Island, the Bahamas, I sought to gain a more detailed understanding of the extent, behavior, and controls on the island’s fresh-water lens using DC electrical resistivity tomography and time-series geochemical data from the Line Hole well field, an inactive source water supply last used in December of 2006. Electrical resistivity profiles were used to image the extent and geologic framework of the fresh water lens in this coastal setting. Time-series geochemical data …
The Effects Of Evapotranspiration Upon Recharge Using The Stable Isotopes Of Oxygen And Hydrogen In The Carbonate Aquifers Of The Cumberland Plateau In Southeast Kentucky, Lee J. Florea
Lee J Florea, PhD, P.G.
In this brief manuscript, we consider the variation of the stable isotopes of oxygen, δ18O, and hydrogen, δ2H, in samples collected during 2010 and 2011 from precipitation and shallow groundwater along the Cumberland Plateau of southeast Kentucky. These data from the 1,900-ha Redmond Creek karst aquifer lend insight into the source and timing of recharge to shallow groundwater in the epigenic karst of the U.S midcontinent. Specifically, we find that only 43% of precipitation remains as potential recharge after accounting for evapotranspiration, and 85% of this potential recharge occurs during only four two-week sampling periods. The isotopic composition of precipitation …
The Karst Of West-Central Florida, Lee J. Florea
The Karst Of West-Central Florida, Lee J. Florea
Lee J Florea, PhD, P.G.
Caves, the cornerstone feature of karst aquifers, are little understood in Florida. This dissertation, which analyzes the morphology, elevation, lithologic setting, and hydrology of caves in west-central Florida, demonstrates that the karst of the unconfined Floridan aquifer differs from the paradigm view of karst presented in modern geology textbooks. The differences reflect setting: eogenetic (west-central Florida) vs. telogenetic (conventional).
