Ground water is the sole freshwater supply for the Eastern Shore Peninsula in Virginia. The fresh ground-water-flow system consists of a water-table aquifer underlain by three confined aquifers separated by intervening confining units. Results of simulations using a sharp-interface, ground-water-flow model indicate that current levels of withdrawal have not caused noticeable saltwater intrusion and that lateral movement of the boundary between saltwater and freshwater is slow and takes place over long periods of time.
