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 …
