Water quality of Lake Whitney, north-central Texas
Jeffrey L. Strause, Freeman L. Andrews
1983, Open-File Report 82-677
The volume-weighted average concentrations of the major dissolved constituents in Lake Whitney on the Brazos River in north-central Texas usually were less than 1,300 milligrams per liter of dissolved solids, 500 milligrams per liter of chloride, and 300 milligrams per liter of sulfate during the 1970-80 water years. The water...
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...
Stratigraphy, structure, and some petrographic features of Tertiary volcanic rocks at the USW G-2 drill hole, Yucca Mountain, Nye County, Nevada
Florian Maldonado, S. L. Koether
1983, Open-File Report 83-732
A continuously cored drill hole designated as USW G-2, located at Yucca Mountain in southwestern Nevada, penetrated 1830.6 m of Tertiary volcanic strata composed of abundant silicic ash-flow tuffs, minor lava and flow breccias, and subordinate volcaniclastic rocks. The volcanic strata penetrated are comprised of the following in descending order:...
Influence of climate on progressive hillslope failure in Redwood Creek Valley, northwestern California
Douglas N. Swanston, Robert Ruhl Ziemer, Richard J. Janda
1983, Open-File Report 83-259
Both creep and earthflow processes control hillslope erosion over large parts of the Redwood Creek basin. The type of process and displacement rates are largely dependent on underlying bedrock type and precipitation input. Progressive creep with rates ranging from 1.0 to 2.5 mm/a dominates on slopes west of the Grogen...
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...
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...
Geoelectric structure of the Gila-San Francisco Wilderness Area, Graham and Greenlee Counties, Arizona, from audio-magnetotelluric data
D. P. Klein, M. J. Baer
1983, Open-File Report 83-815
Electromagnetic induction data using distant field sources, mostly of natural origin, in the frequency range of 4.5-27,000 Hz are analyzed to depict the geoelectric structure in an area of volcanic-rock cover located in southeastern Arizona between the Morenci and Safford porphyry copper deposits. The data for each station consist of...
Data for ground-water studies of the San Juan Basin, New Mexico (1982-83)
R.L. Klausing, G. E. Welder
1983, Open-File Report 84-135
Ground-water data that can be used for futher hydrologic studies in the San Juan structural basin of New Mexico are reported. Descriptions and a location map of 64 observation wells, a list of water levels measured in the observation wells, water-level hydrographs of 32 wells, 15 partial chemical analyses of...
Water-resources investigations of the U.S. Geological Survey in Kansas; fiscal years 1981 and 1982
J. F. Kenny, L. J. Combs
1983, Open-File Report 83-932
One of the primary missions of the U.S. Geological Survey in Kansas is to investigate the occurrence, quantity, quality, distribution, and movement of surface and groundwater throughout the State. Primary activities include the systematic collection, analysis, and interpretation of hydrologic data, evaluation of water demands, and water-resources research. Hydrologic investigations...
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)...
Geohydrology and water resources of the Papago Farms-Great Plain area, Papago Indian Reservation, Arizona, and the upper Rio Sonoyta area, Sonora, Mexico
K.J. Hollett
1983, Open-File Report 83-774
The Papago Farms-Great Plain and upper Rio Sonoyta study area includes about 490 square miles in south-central Arizona and north-central Sonora, Mexico. In the study area 23,700 acre-feet of ground water from the basin-fill deposits was used to irrigate more than 5,000 acres in 1981. Surface water is not a...
A seismic study of Yucca Mountain and vicinity, southern Nevada; data report and preliminary results
L.R. Hoffman, W. D. Mooney
1983, Open-File Report 83-588
From 1980 to 1982, the U.S. Geological Survey conducted seismic refraction studies at the Nevada Test Site to aid in an investigation of the regional crustal structure at a possible nuclear waste repository site near Yucca Mountain. Two regionally distributed deployments and one north-south deployment recorded nuclear events. First arrival...
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...
