L30 – Located Within and Along the Eastern Edge of WCA3-B

This cluster of stations along the L30 levee has wells that measure water level and flow at various points in the aquifer. Click image for a larger version.
Nine monitoring stations were installed at L30 during 2006-2010 by the USACE to provide data supporting the proposed L-31N (L-30) Seepage Management Pilot Project (SMPP) Baseline Hydrogeologic Testing project. This project was designed by the USACE to identify and determine information necessary to resolve critical uncertainties associated with technologies that will be considered for controlling seepage from natural areas in Everglades National Park and Water Conservation Area 3B (WCA-3B). The L-30 North SMPP Baseline Hydrogeologic Testing project consisted of the installation of wells and instruments in the area of a proposed cut-off wall to provide baseline data prior to installation of a pilot seepage wall. The area of the study is located along a levee to the L-30 Canal and constructed specifically for sensor deployment and measurement of apparent flow velocities and water levels in flow zones. Most wells are screened at discrete 2-foot intervals, located in Biscayne Aquifer flow zones, as determined from optical borehole imagery. Individual monitor wells are instrumented with sensors and pressure transducers (see Sensors). The L-30 wells have instrumentation, that enables measurement of ground and surface water levels, ground water flow velocity, specific conductance, and temperature.
