Description: A number of studies have evaluated hydraulic conductivity, permeability, and transmissivity of the St. Peter Sandstone, including Kreutzfeld (1982) and Mandle and Kontis (1992). We chose to use a combination of results from Kreutzfeld (1982) and Mandle and Kontis (1992). Kreutzfeld (1982) derived permeability data from core samples and his data cover central and southern Illinois. Mandle and Kontis (1992) derived hydraulic conductivity data from well-test data, which cover northern and central Illinois, northern and central Indiana, and northern Missouri. Because Kreutzfeld's (1982) data were derived from individual core samples, they were much more variable than those of Mandle and Kontis (1992).
