The vertical distribution of selected trace metals and organic compounds in bottom materials of the proposed lower Columbia River export channel, Oregon, 1984
Gregory J. Fuhrer, Arthur J. Horowitz
1989, Water-Resources Investigations Report 88-4099
A proposal to deepen the lower Columbia River navigation channel in Oregon prompted a study of the vertical distribution of selected trace metals and organic compounds in bottom sediments. These data are needed to evaluate the effects of dredging and disposal operations. Elutriation testing of bottom material indicated chemical concentrations...
Measurement of time of travel in streams by dye tracing
F. A. Kilpatrick, James F. Wilson
1989, Techniques of Water-Resources Investigations 03-A9
The use of fluorescent dyes and tracing techniques provides a means for measuring the time-of-travel and dispersion characteristics of steady and gradually varied flow in streams. Measurements of the dispersion and concentration of dyes give insight into the behavior of soluble contaminants that may be introduced into a stream. This manual describes methods of measuring time...
Use of surface-geophysical methods to assess riverbed scour at bridge piers
S.R. Gorin, F.P. Haeni
1989, Water-Resources Investigations Report 88-4212
A ground-penetrating-radar system, and three seismic systems--color fathometer, tuned transducer, and black-and-white fathometer--were used to evaluate river-bed scour at the Charter Oak, Founder 's and Bulkeley Bridges in Hartford, Connecticut. Cross-sections of the channel and some lateral sections were run at each bridge in June and July 1987, and significant...
Preliminary assessment of sources, distribution, and mobility of selenium in the San Joaquin Valley, California
R. J. Gilliom
1989, Water-Resources Investigations Report 88-4186
Selenium in tile drain water from parts of the western San Joaquin Valley, California, has adversely affected fish and waterfowl where drain water was impounded. Soils in these drained areas were derived from Coast Range marine sedimentary formations, were naturally saline and probably contained abundant soluble selenium. Decades of irrigation...
Sedimentation of Lake Taneycomo, Missouri, 1913-1987
W.R. Berkas
1989, Water-Resources Investigations Report 89-4160
On the basis of the data from a sedimentation survey done by the U.S. Department of Agriculture, Soil Conservation Service, during 1935 and data collected by the U.S. Geological Survey during 1987, the volume of sediment accumulated in Lake Taneycomo from 1913 to 1935 and 1913 to 1987 was determined....
Chemical characteristics, including stable-isotope ratios, of surface water and ground water from selected sources in and near East Fork Armells Creek basin, southeastern Montana, 1985
R. F. Ferreira, J. H. Lambing, R. E. Davis
1989, Water-Resources Investigations Report 89-4024
Water samples were collected from 29 sites to provide synoptic chemical data, including stable-isotope ratios, for an area of active surface coal mining and to explore the effectiveness of using the data to chemically distinguish water from different aquifers. Surface-water samples were collected from one spring, four sites on East...
Estimation of flood-frequency characteristics and the effects of urbanization for streams in the Philadelphia, Pennsylvania area
J.F. Bailey, W.O. Thomas Jr., K. L. Wetzel, T.J. Ross
1989, Water-Resources Investigations Report 87-4194
This report provides a method for estimating the magnitude and frequency of floods for small streams in the Philadelphia, Pennsylvania area. Data collected at 21 streamflow gaging stations were used in a multiple-regression analysis to develop equations for computation of peak-flow characteristics. The flood equations were determined by relating flood-frequency...
Quality of bottom material and elutriates in the lower Willamette River, Portland Harbor, Oregon
Gregory J. Fuhrer
1989, Water-Resources Investigations Report 89-4005
In October 1983 the U.S. Geological Survey, in cooperation with the U.S. Army Corp of Engineers, collected bottom-material and water samples from Portland Harbor, Oregon to determine concentrations of trace metals and organic compounds in elutriate-test filtrate and bottom material. Of the trace metals examined in bottom material, concentrations of...
Water resources of Sedgwick County, Kansas
H.E. Bevans
1989, Water-Resources Investigations Report 88-4225
Hydrologic data from streams, impoundments, and wells are interpreted to: (1) document water resources characteristics; (2) describe causes and extent of changes in water resources characteristics; and (3) evaluate water resources as sources of supply. During 1985, about 134,200 acre-ft of water (84% groundwater) were used for public (42%), irrigation,...
Evaluation of field sampling and preservation methods for strontium-90 in ground water at the Idaho National Engineering Laboratory, Idaho
L.D. Cecil, L.L. Knobel, S.J. Wegner, L.L. Moore
1989, Water-Resources Investigations Report 89-4146
Water from four wells completed in the Snake River Plain aquifer was sampled as part of the U.S. Geological Survey 's quality assurance program to evaluate the effect of filtration and preservation methods on strontium-90 concentrations in groundwater at the Idaho National Engineering Laboratory. Water from each well was filtered...
Ground-water use in the coastal plain of Maryland, 1900-1980
J. C. Wheeler, F.D. Wilde
1989, Open-File Report 87-540
This report presents groundwater withdrawal data from 1900 through 1980 for Maryland counties lying with the Coastal Plain physiographic province, as well as a summary section for the total Maryland Coastal Plain. The types of water use included are domestic, military, water supplier, industrial/commercial, and irrigation. The data were obtained...
Results of hydrologic research at a low-level radioactive-waste disposal site near Sheffield, Illinois
Barbara J. Ryan, editor(s)
1989, Open-File Report 88-318
Ten years of hydrologic research have been conducted by the U.S. Geological Survey at a commercial low-level radioactive-waste disposal site near Sheffield, Illinois. Research included studies of microclimate, evapotranspiration, and tritium release by plants; runoff and land modification; water movement through a trench cover; water and tritium movement in the...

L. J. Combs (compiler)
1989, Open-File Report 89-592
The principal mission of the U.S. Geological Survey, Water Resources Division, 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....
Geohydrology, simulation of ground-water flow, and ground-water quality at two landfills, Marion County, Indiana
R.F. Duwelius, T. K. Greeman
1989, Water-Resources Investigations Report 89-4100
Geologic, hydrologic, and water-quality data were collected at the Julietta and Tibbs-Banta landfills in Marion County. Both landfills were closed in the mid-1970's, and sewage sludge mixed with dirt was spread on the landfills in the mid-1980's as part of a revegetation project. The landfills were constructed in unconsolidated glacial sediments...
