Borehole geophysical logs were collected in March 2010 from a 1,020-foot deep core hole drilled at Fort Pulaski, Chatham County, Georgia. Using these logs, a relation was developed between borehole geophysical log response and known water-quality variations in the Floridan aquifer system. Formation factors determined from this analysis ranged from 4.5 to 5.6. A value of 0.75 for the tortuosity and a value of 1.6 for the cementation factor provided a fairly good fit between log-derived salinity values and water-quality values from the well samples. Formation factors determined at the Fort Pulaski core site could be applied to similar rock types in the subsurface of coastal Georgia; and this methodology could be applied to geophysical log data to expand the current knowledge about saline aquifers in coastal Georgia and throughout the southeastern United States.
