A rise in sea level will cause saline water to intrude up estuaries including those adjacent to aquifers with major pumping centers. During a drought a significant amount of saline estuary water can recharge certain aquifer systems. The objective of this study is to consider various response options that are appropriate to minimize the impact of the salinity intrusion into the Delaware Estuary and adjacent Potomac-Raritan-Magothy aquifer system (PRM) during a drought. Extraction wells and a combination of extraction and injection wells are considered during the drought period. The results indicate that the PRM can be adequately protected during a drought with an adequate short term water supply and delivery system.
