Detailed Description

Saltwater Intrusion: Borehole geophysical log suite from Q-3655, a deep test boring along the western boundary of John F. Kennedy International Airport.  The calculated EM conductivity log clearly delineates saltwater intrusion in the upper glacial, Jameco, Magothy, and Lloyd aquifers.  Using the USGS EM conductivity equation estimated chloride concentrations of 20,000 mg/L in the Magothy aquifer and 15,000 mg/L in the Lloyd aquifer were determined.
