Ground-water withdrawals in New Jersey's Coastal Plain in 1992 caused water level declines and saltwater intrusion. A computer model was used to simulate different withdrawal scenarios. By reducing withdrawals in critical areas, water levels recovered significantly in the aquifers. In scenarios with withdrawal restrictions, water levels improved in the Upper Potomac-Raritan-Magothy, Englishtown, and Wenonah-Mount Laurel aquifers by 2020. This study shows that managing ground-water withdrawals can help prevent saltwater intrusion and depletion of the water supply in the Coastal Plain.
