Abstract

This project empirically determined the controls of groundwater discharge potential and surface water chemistry in southern Taylor Slough, Everglades National Park, Florida. Potential for groundwater discharge was calculated as the difference in equivalent freshwater stage between groundwater and surface water on a daily basis for two sites (upland and coastal) along southern Taylor Slough. Upstream water stages were shown to vary most similarly to the timing of groundwater discharge potential in coastal Taylor Slough. Surface water major ion chemistry did not apparently change as a result of groundwater discharge potential. Surface water major ion chemistry at the coastal site was controlled by surface water flow direction, while at the more inland site surface water major ion chemistry was controlled by upstream water levels and evapotranspiration. Surface water phosphorus concentrations at the coastal site were controlled by groundwater discharge and flows of local surface water.
