Investigation of acidity and other water-quality characteristics of Upper Oyster Creek, Ocean County, New Jersey
Thomas V. Fusillo, J.C. Schornick Jr., H.E. Koester, D.A. Harriman
1980, Water-Resources Investigations Report 80-10
Water-quality data collected in the upper Oyster Creek drainage basin, Ocean County, N.J., indicate that the stream has excellent water quality except for a persistently low pH. The mean concentrations of the major inorganic ions were all less than 6.0 milligrams per liter. Mean concentrations of total nitrogen and total...
Water-quality assessment of the Cypress Creek watershed, Warrick County, Indiana
Linda L. Bobo, Charles A. Peters
1980, Water-Resources Investigations Report 80-35
The U.S. Soil Conservation Service needs chemical, biological, microbiological, and hydrological data to prepare an environmental evaluation of the water quality in the Cypress Creek watershed, Warrick County, Ind., before plans can be devised to (1) improve water quality, (2) minimize flooding, (3) reduce sedimentation, and (4) provide adequate outlets...
Quality of surface water in the coal-mining region, southwestern Indiana, March and May 1979
Danny E. Renn, Stephen E. Ragone, William G. Wilber
1980, Open-File Report 80-970
On August 3, 1977, the Surface Mine Control and Reclamation Act, Public Law 95-87 (the Act) was enacted by the 95th Congress. Under Section 507(b)(11) of the Act, an appropriate Federal or State agency must provide applicants for coal-mining permits hydrologic and water-quality information for the general use of proposed...
Dinkum Sands
Erk Reimnitz, Robin Ross, Peter W. Barnes
1980, Open-File Report 80-360
The State/Federal Beaufort Sea lease sale in December 1979 attracted over one billion dollars in bids. Tracts with the highest bids, and apparently with the highest oil potential, lie in the area south of Dinkum Sands, and within a three-mile radius of the shoal (Fig. 1). Jurisdiction over the tracts...
Digital-computer model of ground-water flow in Tooele Valley, Utah
Allan C. Razem, Scott D. Bartholoma
1980, Open-File Report 80-446
A two-dimensional, finite-difference digital-computer model was used to simulate the ground-water flow in the principal artesian aquifer in Tooele Valley, Utah. The parameters used in the model were obtained through field measurements and tests, from historical records, and by trial-and-error adjustments. The model was calibrated against observed water-level changes that...
Land-surface subsidence in the Texas coastal region
Karl W. Ratzlaff
1980, Open-File Report 80-969
Land-surface subsidence has been mapped in the Houston-Galveston area and is known to have occurred in other areas within the Texas coastal region. Most of the subsidence has been caused by both the withdrawal of ground water and by the production of oil, gas, and associated ground water. Land-surface subsidence was...
Test and calibration of the Seismic Research Observatory
Jon Peterson, Charles R. Hutt, L. Gary Holcomb
1980, Open-File Report 80-187
The Seismic Research Observatory (SRO) network is generating an important new data base for seismological research. The SRO systems have extended both the range and resolution of seismic measurements beyond the limits of conventional seismographs and the data are recorded in digital format making it convenient to automate processing and...
Preliminary observations of noise spectra at the SRO and ASRO stations
Jon Peterson
1980, Open-File Report 80-992
The seismic noise spectra presented in this report were derived from SRO and ASRO station data for the purpose of evaluating the performance of the seismic instruments. They are also useful for constructing a spectral estimate of earth noise at a quiet site based on noise samples obtained from a...
Hydrologic data for urban studies in the San Antonio, Texas, metropolitan area, 1977
Roberto Perez, Lynn Harmsen
1980, Open-File Report 80-743
Hydrologic investigations of urban drainage basins in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Dallas, Dallas County, Fort Worth, Houston, and San Antonio.The Geological Survey, in cooperation with the Texas Department of Water Resources, expanded the existing gaging-station network...
Hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project: Morgan County, Colorado
Alan W. Burns
1980, Water-Resources Investigations Report 80-46
A hydrologic analysis of the proposed Badger-Beaver Creeks artificial-recharge project in Morgan County, Colo., was made with the aid of three digital computer models: A canal-distribution model, a ground-water flow model, and a stream-aquifer model. Statistical summaries of probable diversions from the South Platte River based on a 27-year period...
Work plan for the Schuylkill River basin, Pennsylvania: Assessment of river quality as related to the distribution and transport of trace metals and organic substances
G.L. Pederson, Thomas H. Yorke, J. K. Stamer
1980, Open-File Report 80-566
The U.S. Geological Survey is making a river-quality assessment of the Schuylkill River basin in Pennsylvania from October 1978 to March 1981. It is part of a continuing program designed to demonstrate the effectiveness of river-quality studies for basin planning and water-resource management. Study objectives include determining (1) presence of...
Ground-water quality in North Idaho
D. J. Parliman, Harold R. Seitz, Michael L. Jones
1980, Open-File Report 80-596
From July 1977 to May 1978, water samples were collected from 116 wells north of the Palouse River in Idaho to define water-quality conditions, on a reconnaissance level, in major aquifers. Geologic and hydrologic data were combined with water-quality data to develop an understanding of factors affecting present and future...
Waste-assimilation capacity of the Arkansas River in Pueblo County, Colorado, as it relates to water-quality guidelines and stream classification
Doug Cain, Duaina Baldridge, Patrick Edelmann
1980, Water-Resources Investigations Report 80-82
The waste-assimilation capacity of a 42-mile reach of the Arkansas River in Pueblo County, Colo., was evaluated using a one-dimensional steady-state water-quality model. The model was calibrated and verified using hydraulic and water-quality data collected in 1976 and 1979. The water-quality con-stituents modeled were 5-day carbonaceous biochemical oxygen demand, total...
Initial report of the petrophysics laboratory; 1977-1979 addendum
Gary R. Olhoeft
1980, Open-File Report 80-522
From the time the author-copy of Circular 789 (Hunt and others, 1979) was prepared until it first appeared in print, significant changes occurred in the Petrophysics Laboratory. To update that report, this open-file report will briefly summarize more recent acquisitions and facilities changes....
