Simulated Effects of Alternative Pumping Strategies on Ground-Water-Flow Patterns and Areas Contributing Recharge to Selected Wells near Kenvil, Morris County, New Jersey Simulated Effects of Alternative Pumping Strategies on Ground-Water-Flow Patterns and Areas Contributing Recharge to Selected Wells near Kenvil, Morris County, New Jersey
Ground-water-flow patterns and areas contributing recharge to supply wells change in response to new or altered pumping stresses. An understanding of these potential changes is essential for the effective evaluation of possible future water-supply alternatives, especially if the supply wells may be vulnerable to contamination from the land surface. Demand for water from a valley-fill and...

Analysis of ground-water flow and saltwater encroachment in the shallow aquifer system of Cape May County, New Jersey Analysis of ground-water flow and saltwater encroachment in the shallow aquifer system of Cape May County, New Jersey
Cape May County, New Jersey, is on a natural peninsula that is virtually surrounded by saltwater. A calibrated quasi-three-dimensional sharp-interface model was used to simulate ground-water flow in the shallow aquifer system under two water-supply-development alternatives for a 30-year planning period. The alternatives involve modest increases in withdrawals in combination with...

Evaluation of saltwater intrusion and travel time in the Atlantic City 800-foot sand, Cape May County, New Jersey, 1992, by use of a coupled-model approach and flow-path analysis Evaluation of saltwater intrusion and travel time in the Atlantic City 800-foot sand, Cape May County, New Jersey, 1992, by use of a coupled-model approach and flow-path analysis
Regional and subregional ground-water-flow models were coupled, and the output was analyzed by a particle-tracking method. The results were then used to assess the effects of ground-water withdrawals on the flow of saltwater in the Atlantic City 800-foot sand in Cape May County, New Jersey, and to estimate the travel time from areas in which the chloride concentration of the ground water...

Hydrologic feasibility of water-supply-development alternatives in Cape May County, New Jersey Hydrologic feasibility of water-supply-development alternatives in Cape May County, New Jersey
Increasing public-supply withdrawals in Cape May County, New Jersey associated with increasing residential and seasonal tourist populations have led to regionally lowered ground-water levels, a reversal of ground-water flow directions toward onshore, and landward encroachment of saltwater in the shallow aquifer system. The three aquifers composing the shallow system are, in order of...
