Reconnaissance of polychlorinated biphenyls in the Arkansas River between Muskogee and Webbers Falls lock and dam, Oklahoma
J.D. Stoner
1980, Open-File Report 80-216
Analysis of samples collected from the Arkansas River between Muskogee and Webbers Falls Lock and Dam, Oklahoma, in November 1978 showed that concentrations of polychlorinated biphenyls in the dissolved and suspended phases were less than the detection limit of 0.1 micrograms per liter. The maximum polychlorinated biphenyl concentration measured in...
A procedure for predicting concentrations of dissolved solids and sulfate ion in streams draining areas strip mined for coal
Hugh E. Bevans
1980, Open-File Report 80-764
Current trends in increased coal production neccessitate the development of techniques to appraise the environmental degradation that results from strip mining. A procedure is introduced for the prediction of dissolved-solids and sulfate-ion concentrations in streams draining strip-mined areas as functions of the percentage of the drainage area that has been...
Analyses of water, bank material, bottom material, and elutriate samples collected near Belzoni, Mississippi (upper Yazoo projects)
David B. Brightbill, Joseph B. Treadway
1980, Open-File Report 80-758
Four core-material-sampling sites and one bottom-material site were chosen by the U.S. Army Corps of Engineers to represent areas of proposed dredging activity along a 24.9-mile reach of the upper Yazoo River. Five receiving-water sites also were selected to represent the water that will contact the proposed dredged material. Chemical...
Preliminary field geotechnical and geophysical logs from a drill hole in the Capps coal field, Cook Inlet region, Alaska
Alan F. Chleborad, Lynn A. Yehle, Henry R. Schmoll, Cynthia A. Gardner
1980, Open-File Report 80-393
The drilling and logging activity described in this report was undertaken in August 1979, as part of the Energy Lands program of the U.S. Geological Survey. The general objectives of the project, of which this work is a part, are to provide an understanding of the nature, location, and extent...
Hydrogeochemistry and simulated solute transport, Piceance Basin, northwestern Colorado
Stanley G. Robson, George J. Saulnier
1980, Open-File Report 80-72
Oil-shale mining activities in Piceance basin in northwestern Colorado could adversely affect the ground- and surface-water quality in the basin. This study of the hydrology and geochemistry of the area used groundwater solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and...
Water-quality characteristics of selected lakes and reservoirs in Colorado
Linda J. Britton, Dennis A. Wentz
1980, Open-File Report 80-436
During the summers and autumns of 1973, 1974, and 1975, water-quality data were collected and compiled for 56 lakes and reservoirs in Colorado. The lakes and reservoirs sampled range from large reservoirs in the eastern part of the State to smaller natural lakes in the higher western parts of the...
