Comments on Geologic Parameters

12c Formation Water Salinity:

Several researchers reported that salinities for the lower Potomac aquifer interval of eastern New Jersey, Delaware, and Maryland (Manheim and Horn, 1968; Hansen, 1984; Trapp and others, 1984; Meisler, 1989; Trapp and Horn, 1997; Pope and Gordon, 1999). We combined information presented by Hansen (1984) and Pope and Gordon (1999) for the GIS.
