Comments on Geologic Parameters

12c Formation Water Salinity:

Formation waters in the St. Peter Sandstone in the southern Illinois, western Kentucky, area are highly mineralized (Meents and others, 1952; Hoholick, 1980; Cartwright and others, 1981). We used the salinity-distribution map of Hoholick (1980) in the GIS because it is the most current and covers a broad region.
