Cape Fear Formation, South Carolina Coastal Plain

Comments on Geologic Parameters

12c Formation Water Salinity:

Several researchers have reported that salinity in the Cape Fear aquifer is moderately high but below 10,000 mg/L (Manheim and Horn, 1968; Brown and others, 1979; Lee, 1985; Miller and others, 1986; Miller, 1990). However, there has not been a systematic study of water chemistry in southeastern South Carolina because of low prospect for use. We used the map of Lee (1985) for the GIS, who referred to the Cape Fear hydrostratigraphic interval as the middle water-bearing zone of the A4 regional aquifer. We chose this map to grid (c12capefear) because it shows the regional distribution of dissolved solids.
