Filtration of water-sediment samples for the determination of organic compounds
Mark W. Sandstrom
1995, Water-Resources Investigations Report 95-4105
This report describes the equipment and procedures used for on-site filtration of surface-water and ground-water samples for determination of organic compounds. Glass-fiber filters and a positive displacement pumping system are suitable for processing most samples for organic analyses. An optional system that uses disposable in-line membrane filters is suitable for...
Water-quality assessment of the Trinity River Basin, Texas - Review and analysis of available pesticide information, 1968-91
R.L. Ulery, M.F. Brown
1995, Water-Resources Investigations Report 94-4218
In 1991 the Trinity River Basin study unit was among the first 20 study units in which work began under full-scale program implementation of the National Water-Quality Assessment Program. A retrospective assessment was undertaken to review and analyze existing pesticide data and related environmental factors. Population and land-use data indicate...
Trace metals and major and rare earth elements in cuttings from five high-temperature wells in the northwest region of The Geysers, California, vapor-dominated geothermal system
Robert O. Fournier, Joseph N. Moore
1995, Open-File Report 95-30
Temperatures within the main vapor-dominated steam reservoir at The Geysers geothermal field generally are in the range 238°C to 244°C. A few deep wells in the northwestern part of the field have penetrated beneath this reservoir into a second vapor-dominated reservoir where temperatures are >315°C, while vapor pressure remains nearly...
Nutrients in ground water and surface water of the United States; an analysis of data through 1992
D. K. Mueller, P. A. Hamilton, D.R. Helsel, K.J. Hitt, B. C. Ruddy
1995, Water-Resources Investigations Report 95-4031
Historical data on nutrient (nitrogen and phosphorus species) concentrations in ground-and surface-water samples were compiled from 20 study units of the National Water-Quality Assessment (NAWQA) Program and 5 supplemental study areas. The resultant national retrospective data sets contained analyses of about 12,000 Found-water and more than 22,000 surface-water samples. These...
Channel change and sediment transport in two desert streams in central Arizona, 1991-92
J. T. Parker
1995, Water-Resources Investigations Report 95-4059
Channel change and suspended-sediment transport were monitored in the Salt and Hassayampa Rivers in Maricopa County, Arizona, during the winter and summer rainy seasons of 1991-92. Flows were moderate. Results illustrate the high instability of these channels and high variability of process and response. A channelized, gravel-paved reach of...
Data on ground-water levels and ground-water/surface-water relations in the Great Miami River and Little Miami River valleys, southwestern Ohio
William P. Yost
1995, Open-File Report 95-357
Hydrogeologic data were collected in September, October, and November 1993 to define the ground-water levels and the ground-water/surface-water relations in the vicinity of Dayton, Ohio. In this report, water levels are listed for 678 wells completed in sand and gravel. Data from 101 streamflow measurements made at selected sites along...
Ground-water conditions and effects of mine dewatering in Desert Valley, Humboldt and Pershing Counties, northwestern Nevada, 1962-91
D.L. Berger
1995, Water-Resources Investigations Report 95-4119
Desert Valley is a 1,200-square-mile, north- trending, structural basin, about 30 miles northwest of Winnemucca, Nevada. Unconsolidated basin-fill deposits exceeding 7,000 feet in thickness constitute the primary ground-water reservoir. Dewatering operations at an open-pit mine began in the Spring of 1985 in the northeast part of Desert Valley. Ground-water withdrawal...
Hydrogeologic and agricultural-chemical data for the South Skunk River alluvial aquifer at a site in Story County, Iowa, 1992-93
Robert C. Buchmiller
1995, Water-Resources Investigations Report 94-4244
A reconnaissance study was conducted during 1992-93 to collect background hydrogeologic and agricultural-chemical data for the South Skunk River alluvial aquifer near Ames, Iowa. Observation wells were drilled to characterize the surficial geologic materials of a field-scale study site and to provide locations for collecting waterlevel and agricultural-chemical data. Walnut...
Propagation and composition of the flood wave on the upper Mississippi River, 1993
John A. Moody
1995, Circular 1120-F
During spring and summer 1993, record flooding inundated much of the upper Mississippi River Basin. The magnitude of the damages-in terms of property, disrupted business, and personal trauma was unmatched by any other flood disaster in United States history. Property damage alone is expected to exceed $10 billion. Damaged highways...
Hydrogeology and simulated effects of ground-water withdrawals for citrus irrigation, Hardee and De Soto counties, Florida
P. A. Metz
1995, Water-Resources Investigations Report 93-4158
The hydrogeology of Hardee and De Soto Counties in west-central Florida was evaluated, and a ground-water flow model was developed to simulate the effects of expected increases in ground-water withdrawals for citrus irrigation on the potentiometric surfaces of the intermediate aquifer system and the Upper Floridan aquifer. In 1988, total...
