Electrical analog model simulations of hydraulic conditions in the Biscayne aquifer were made at proposed inland well-field sites in Dade County, Florida. Simulated drawdowns of water levels after 7 months of continuous pumping at 50, 100, and 150 million gallons per day were obtained at each site. Simultaneous pumping of each of the sites at 50 million gallons per day showed that after 7 months pumping there would be interference between proposed well fields. (Woodard-USGS)
