A description of aquifer units in western Oregon
W. D. McFarland
1983, Open-File Report 82-165
Hydrogeologic information for western Oregon was compiled to aid the U.S. Environmental Protection Agency in evaluating proposals for underground injection of waste fluid. Geologic formations were grouped into seven aquifer units according to hydraulic and geologic similarities. The bedrock aquifer units in the Klamath Mountains, Coast Range, and Western Cascade...
The Emma Bell deposit, Siskiyou Co., California: A possible low-grade source of chromite
B. R. Lipin, Nicholas Wetzel, S. M. Heinrich
1983, Open-File Report 83-816
The Emma Bell chromite deposit in Siskiyou County, California contains over 5 million tons of dunite averaging about 4 percent Cr2O3. Chromite is not evenly disseminated throughout the dunite, however. For the most part the deposit consists of many chromite-rich bands in sharp contact with, and separated by, common dunite...
Water resources of the Tulalip Indian Reservation, Washington
B. W. Drost
1983, Open-File Report 82-648
Water will play a significant role in the future development of the Tulalip Indian Reservation. Ground-water resources are sufficient to supply several times the 1978 population. Potential problems associated with increased ground-water development are saltwater encroachment in the coastal areas and septic-tank contamination of shallow aquifers. There are sufficient good-quality...
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Allegheny National Forest, Warren County, Pennsylvania
N. L. Hickling, Stanley P. Schweinfurth, Betty M. Adrian
1983, Open-File Report 83-5
A reconnaissance geochemical survey of the Allegheny Front and Hickory Creek Roadless Areas, Warren County, Pennsylvania, was made by members of the U.S. Geological Survey (USGS) to test for indistinct or unexposed mineral deposits that might be recognized by geochemical halos. Analyses using semiquantitative emission spectrography and atomic absorption for...
Report of the U.S. Geological Survey's analytical evaluation program; standard reference water samples M-82 (major constituents), T-83 (trace constituents), N-8 (nutrients), and P-2 (precipitation snowmelt)
V.J. Janzer
1983, Open-File Report 83-864
The U.S. Geological Survey began an interlaboratory testing program of reference water samples in 1962. Principal purposes of the program are to provide a means for participating water laboratories to: (1) identify analytical problem areas; (2) ascertain the accuracy and precision of common water analyses and analytical methods and; (3)...
Ground-water data for Georgia, 1982
H.R. Stiles, S.E. Matthews
1983, Open-File Report 83-678
Continuous water level records from 105 wells, and more than 2 ,000 water level measurements made in Georgia during 1982 provided the basic data for this report. Selected wells illustrate the effects that changes in recharge and pumpage have had on the various groundwater resources in the State. Daily mean...
Public-supply pumpage in Wisconsin
C.L. Lawrence, B.R. Ellefson, R. D. Cotter
1983, Open-File Report 83-931
This report summarizes the amounts and distribution of the pumpage of ground water for public supplies from four aquifers in Wisconsin. The data are for 1979 and reflect the pumpage from about 1,100 wells in 485 communities. The distribution and amount of pumpage is estimated to be similar for subsequent...
Inventory and analyses of information for flood plain management in North Dakota
D. G. Emerson, J. D. Wald
1983, Open-File Report 84-53
Governmental units that have been identified as having flood hazard areas but do not have detailed base flood information are required to use the "best available data" to regulate new development or expansion of existing development in flood prone areas. Information for flood plain management has been identified for 95...
Explanation to accompany reconnaissance geologic map of the De Long Mountains A3, B3, and parts of A4, B4 quadrangles, Alaska
Charles F. Mayfield, S.M. Curtis, Inyo Ellersieck, I.L. Tailleur
1983, Open-File Report 83-183
This map is one of a series of three reconnaissance geologic maps of the southern De Long Mountains quadrangle (fig. 1). Because the geology in the three map areas is similar, a composite map explanation has been designed to facilitate their combined use and give a better perspective of the...
Spectral analysis of the 1976 aeromagnetic survey of Harrat Rahat, Kingdom of Saudi Arabia
H. Richard Blank, Hamdy S. Sadek
1983, Open-File Report 83-640
Harrat Rahat, an extensive plateau of Cenozoic mafic lava on the Precambrian shield of western Saudi Arabia, has been studied for its water resource and geothermal potential. In support of these investigations, the thickness of the lava sequence at more than 300 points was estimated by spectral analysis of low-level...
Water-level records for the northern High Plains of Colorado, 1979-83
Joe L. Blattner, Bruce D. Rasmuson
1983, Open-File Report 83-253
Water-level measurements were made in 638 wells in the winter of 1982-83, in the northern High Plains of Colorado. The water-level measurements for the winter of 1982-83 and for four preceding winters are given in a table, which also contains the location, depth, land-surface elevation and the aquifer for each...
