Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-supply wells in Riverhead have experienced increased chloride concentrations recently due to the encroachment of saltwater. Riverhead is underlain by a sequence of unconsolidated deposits ranging in age from Pleistocene to Upper Cretaceous that overlie a basement complex of Precambrian bedrock. These deposits are part of Long...
