Regional flow in the Dakota aquifer: A study of the role of confining layers
John D. Bredehoeft, C. E. Neuzil, P. C. Milly
1983, Water Supply Paper 2237
The Dakota Sandstone in South Dakota is one of the classic artesian aquifers; it was first studied by N. H. Darton at the turn of the century. Since then, hydrogeologists have debated the source of the large quantities of water which have been discharged by artesian flow from the Dakota....
Hydrogeologic and water-quality characteristics of the St. Peter aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 83-4200
Quality of water in the St. Peter aquifer is generally acceptable for most uses. Sulfate concentrations increase toward the southwestern part of the aquifer because of highly mineralized leakage from overlying Cretaceous deposits. Concentrations of sodium, magnesium, and sulfate generally increase to the west, and those of calcium, bicarbonate, and...
Laboratory safety handbook
E.L. Skinner, C.A. Watterson, J.C. Chemerys
1983, Open-File Report 83-131
Safety, defined as 'freedom from danger, risk, or injury,' is difficult to achieve in a laboratory environment. Inherent dangers, associated with water analysis and research laboratories where hazardous samples, materials, and equipment are used, must be minimized to protect workers, buildings, and equipment. Managers, supervisors, analysts, and laboratory support personnel...
Distribution of selected chemical constituents in water from the Floridan aquifer, Southwest Florida Water Management District
M.A. Corral Jr.
1983, Water-Resources Investigations Report 83-4041
Generalized maps showing variations in concentration of chlorides, sulfates, hardness, and dissolved solids in the Floridan aquifer have been prepared as part of a cooperative program with the Southwest Florida Water Management District. This report covers 10 counties and parts of 6 others comprising the District. Data used to develop...
Water resources data, Wyoming, water year 1982
E.S. Denison, J.R. Schuetz, Samuel J. Rucker IV
1983, Water Data Report WY-82-1
Water resources data for the 1982 water year for Wyoming consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains discharge records for 185 gaging stations; stage only...
Summary of water withdrawals in the United States, 1950-80
William B. Mann, Wayne B. Solley, Edith B. Chase
1983, Open-File Report 83-207
Estimated use of water in the United States increased from 180 bgd (billion gallons per day) in 1950 to 450 bgd in 1980. During this same time population increased from about 150 million to about 230 million. Data on consumptive use are not available for the first decade of the...
The mineral resource potential of the Harrat Nawasif, sheet 21/42 C, Ranyah, sheet 21/42 D, and Jabal Dalfa, sheet 21/43 C quadrangles, Kingdom of Saudi Arabia
Michael D. Fenton
1983, Open-File Report 83-372
Areas with mineral resource potential in the Harrat Nawasif, Ranyah, and Jabal Dalfa quadrangles in the central Precambrian Shield of Saudi Arabia have been identified by reconnaissance rock geochemistry and inspection of ancient prospects. Locally anomalous areas in perthitic, alkalic granite terrane in the Ranyah quadrangle possibly contain niobium, zirconium,...
The mineral resource potential of the Thaniyah and Al Ufayriyah quadrangles, sheets 20/42 C and 20/42 A, Kingdom of Saudi Arabia
Michael D. Fenton
1983, Open-File Report 83-388
Areas with mineral resource potential in the Thaniyah and Al Ufayriyah quadrangles in the central Precambrian Shield of Saudi Arabia have been identified by reconnaissance rock geochemistry and inspection of ancient prospects. Locally anomalous areas in plutonic terrane have been defined as possible sources of tin, molybdenum, or base metal...
The mineral resource potential of the Wadi al Jarir and Al Jurdhawiyah quadrangles, sheets 25/42C and 25/42D, Kingdom of Saudi Arabia
Michael D. Fenton
1983, Open-File Report 83-368
Areas with potential for metallic mineral deposits in the Wadi al Jarir and Al Jurdhawiyah quadrangles, northeastern Arabian Shield, have been identified by reconnaissance rock geochemistry, inspection of ancient prospects, and interpretation of previous work. The ancient prospects of Abraq Shawfan, Abraq Shawfan South, Ad Du'ibi, Ad Du'ibi West, and...
