Chemical and physical characteristics of natural ground waters in Michigan: A preliminary report
T. Ray Cummings
1980, Open-File Report 80-953
Wide variations occur in the chemical and physical characteristics of natural groundwaters in Michigan. Dissolved-solids concentrations range from 23 to 2,100 milligrams per liter. Waters having low dissolved-solids concentrations are calcium bicarbonate waters. Sodium, sulfate, and chloride increase as mineralization increases. Iron, aluminum, and titanium are higher at some locations...
Annotated bibliography of spectrophotometric studies in the system U-Fe-Se-S-O-H, 1967-78
K.A. McGee, A. Jefferson Sutton, Nicholas John Susak
1980, Open-File Report 80-199
Preparation of this bibliography was originally begun to supply background information on previous ultraviolet and visible spectrophotometric studies on various chemical species thought to be important in the formation of sedimentary uranium deposits; we also thought that preparing the bibliography would help direct experimental efforts to determine the association of...

This Directory provides the names, addresses, and telephone numbers of all NAWDEX member organizations and their designated...
Development of a digital model of ground-water flow in deeply weathered crystalline rock, Chester County, Pennsylvania
Laurence J. McGreevy, Ronald A. Sloto
1980, Water-Resources Investigations Report 80-2
The model developed in this study simulates .recharge to, flow through, and discharge from the water-table aquifer in the upper Pickering Creek basin, a 5.98-square-mile basin representative of most of Chester County, Pennsylvania. The two-dimensional finite-difference model of Trescott, Pinder, and Larson was used with slight modification. The way ground-water...
