Delineation and description of the regional aquifer systems of Tennessee; Cumberland Plateau aquifer system
J. V. Brahana, J. A. Macy, Dolores Mulderink, Dawn Zemo
1986, Open-File Report 82-338
The Cumberland Plateau aquifer system consists of Pennsylvanian sandstones, conglomerates, shales, and coals which underlie the Cumberland Plateau in Tennessee. Major water-bearing zones occur within the sandstones and conglomerates in interconnected fractures. The water-bearing formations are separated by shale and siltstone that retard the vertical circulation of ground water, The...
Delineation and description of the regional aquifers of Tennessee; basal sandstone aquifer west of the Valley and Ridge Province
J. V. Brahana, M. W. Bradley, J. A. Macy, Dolores Mulderink
1986, Open-File Report 82-762
The basal sandstone aquifer is believed to underlie most of Tennessee west of the Valley and Ridge Province. It is a Cambrian sandstone that overlies the granites of the Precambrian basement complex. The basal sandstone is a poorly known resource defined only by 14 data points (wells) for the entire...
Physical and chemical data for the Sacramento River at Rio Vista, California, November 1983 through November 1984
Allan Y. Ota, L. E. Schemel, S.W. Hager
1986, Open-File Report 86-229
Physical and chemical data for the Sacramento River at Rio Vista , California, for the period of November 1983 through November 1984 are presented in this report. Measurements include specific conductance, alkalinity, suspended particulate matter, and the dissolved inorganic nutrients: nitrite, nitrate + nitrite, ammonium, dissolved silica, and ortho-phosphate. Numerical...

Water-table decline in the south-central Great Basin during the Quaternary Period; implications for toxic-waste disposal
I.J. Winograd, Barney J. Szabo
1986, Open-File Report 85-697
The distribution of vein calcite, tufa, and other features indicative of paleo-groundwater discharge, indicates that during the early to middle Pleistocene, the water table at Ash Meadows, in the Amargosa Desert, Nevada, and at Furnace Creek Wash, in east-central Death Valley, California, was tens to hundreds of meters above the...
Geology and geochronology of the Healy quadrangle, Alaska
Bela Csejtey Jr., M. W. Mullen, D. P. Cox, W. G. Gilbert, W. E. Yeend, T. E. Smith, Clyde Wahrhaftig, Campbell Craddock, W. M. Brewer, K. W. Sherwood, R. G. Hickman, G. D. Stricker, D. R. St. Aubin, D. J. Goerz III

Detection of contaminant plumes in ground water of Long Island, New York, by electromagnetic terrain-conductivity surveys
Thomas J. Mack, P. E. Maus
1986, Water-Resources Investigations Report 86-4045
Electromagnetic terrain conductivity surveys were conducted at four landfills in Suffolk county and at an artificial recharge site in Nassau County to assess the feasibility of this technique for detecting contaminant plumes. The technique was successful at three of the landfills; results compared closely with those indicated by specific conductance...
Analyses of flood-flow frequency for selected gaging stations in South Dakota through September 1985
E.B. Hoffman, M.E. Freese, D.R. Winter
1986, Open-File Report 86-496
Analyses of flood-flow frequency were made for 80 active continuous-record gaging stations and 105 discontinued crest-stage partial-record stations in South Dakota with 10 or more years of record. The analyses were developed using the log-Pearson Type III procedure recommended by the U.S. Water Resources Council (Interagency Advisory Committee on Water...
Use and availability of continuous streamflow records in Wyoming
J.R. Schuetz
1986, Open-File Report 85-685
This report documents a survey that identifies local, State, and Federal uses of data from 139 continuous-record, surface-water stations, presently (1984) operated by the Wyoming District of the U. S. Geological Survey; identifies sources of funding pertaining to collections of streamflow data; and presents frequency of data availability. Uses of...
