The ideal plan would meet projected demands \nand minimize adverse effects on currently used sources of potable, non-\npotable, and ecological water supplies. The U.S. Geological Survey used \ntwo previously developed groundwater flow models, as well as a newly \ndeveloped groundwater flow model, to evaluate the shallow and deep aquifer \nsystems in Cape May County.  The groundwater flow in the shallow and \ndeep aquifer systems of Cape May County were simulated separately. \nFlow in the shallow aquifers was simulated with a newly developed small-cell-\nsize numerical model extending to the hydrologic boundaries. The saltwater \ntransport modeling code, SEAWAT, was used to model the shallow system \nbecause of the accurate treatment of variable-density groundwater (saltwater \nfront) and surface-water boundary (ecological-water supply) conditions. Flow \nin the deep aquifers was simulated using MODFLOW-2000 with a previously \ndeveloped medium-cell-size numerical model encompassing Cape May County. \nThis sub-regional groundwater-flow model (CMAC) was originally developed by \nVoronin (https://doi.org/10.3133/wri954280) to simulate advective flow in the \nAtlantic City 800-foot sand from the estimated 250-mg/L isochlor toward Stone \nHarbor. For this study, the CMAC model was revised to include the Rio Grande \nwater-bearing zone and recalibrated with recent (2003) withdrawal data and \nwater-level measurements. Boundary flows to the CMAC model were provided \nfrom the New Jersey Coastal Plain regional model (NJCP SHARP) \n(https://doi.org/10.3133/wri984216).  This coarse-cell-size Coastal Plain-wide \nmodel uses the SHARP model code and simulates saltwater movement by \ntreating the transition from freshwater to saltwater as a sharp interface, and \ntherefore, only predicts large-scale movements of the 10,000-mg/L isochlor.  \nTo predict the effects of future actions on the water supplies, three baseline \nand six future scenarios were created and simulated with these three models. \nDepending on the scenario, proposed production wells would be installed in \nlocations far from the saltwater fronts, in deep freshwater aquifers, in deeper \nsaltwater aquifers, or proposed injection wells would be installed to inject \nreused water to create a freshwater barrier to saltwater intrusion.  Particle-\ntracking was used with the CMAC model to estimate groundwater-flow paths \nand travel time from the location of the 250-mg/L isochlor to production wells \nor hypothetical production wells. This USGS data release contains all the \ninput and output files for the simulations described in the associated model \ndocumentation report (https://doi.org/10.3133/sir20095187).
