E.A. Thomson, Samuel N. Luoma, C.E. Johansson, D.J. Cain
1984, Water Research (18) 755-765
Sediments and an indicator organism (Macoma balthica, a deposit-feeding bivalve) were used to assess the relative importance of secondary sewage, urban runoff, a landfill containing metal-enriched ash wastes and a yacht harbor in contributing to Ag, Cu and Zn enrichment in South San Francisco Bay. Spatial gradients in sediments and...
Development and evaluation of a gas chromatographic method for the determination of triazine herbicides in natural water samples
T.R. Steinheimer, M.G. Brooks
1984, International Journal of Environmental Analytical Chemistry (17) 97-111
A multi-residue method is described for the determination o triazine herbicides in natural water samples. The technique uses solvent extraction followed by gas chromatographic separation and detection employing nitrogen-selective devices. Seven compounds can be determined simultaneously at a nominal detection limit of 0.1 μg/L in a...

Simulation of ground-water flow in a mined watershed in eastern Ohio
J. S. Weiss, A. C. Razem
1984, Groundwater (22) 549-560
A 43-acre watershed in Muskingum County, Ohio, was studied to determine the hydrologic consequences of strip mining for coal. A quantitative description of the effects on the ground-water flow components of the hydrologic system has been obtained using digital models.The premining watershed was characterized by...
VERTICAL MOVEMENT OF GROUND WATER UNDER A LANDFILL, ANCHORAGE, ALASKA.
Gordon L. Nelson
1984, Conference Paper
A thorough review of existing ground-water information may, in some cases, be adequate to estimate rates of migration of pollutants. Analysis of data from well-performance tests and from hydrologic-data stations near a landfill in Anchorage, Alaska, indicates that pollutants migrating downward toward a confined aquifer that supplies water to three...
Paleohydrologic regimes in the southwestern Great Basin, 0-3.2 my ago, compared with other long records of "gobal" climate
G.I. Smith
1984, Quaternary Research (22) 1-17
Nine distinct paleohydrologic regimes in the southwestern Great Basin over the last 3.2 my are recorded by the lacustrine deposits in KM-3, a 930-m core from Searles Lake, California. These are characterized as being "wet," "intermediate," or "dry" (like today). Excepting the present incomplete regime, each lasted 0.12 to 0.76...

POTENTIAL FOR NITROSAMINE FORMATION RESULTING FROM THE USE OF RHODAMINE WT FOR TIME-OF-TRAVEL STUDIES: A COMBINED LABORATORY AND FIELD INVESTIGATION.
Sharon M. Johnson, Thomas R. Steinheimer
1984, Conference Paper, National Meeting - American Chemical Society, Division of Environmental Chemistry
Rhodamine WT is used by surface water hydrologists for time of travel and dispersion studies in which flow characteristics of surface streams are determined. Surface water contamination by nitrosamines formed from Rhodamine WT and nitrite ion has been studied. A method for residue analysis of N-nitrosodiethylamine (NDEA) has been developed...
Hydrologic analysis of the High Plains aquifer system in Box Butte County, Nebraska
R. A. Pettijohn, Hsiu-Hsiung Chen
1984, Water-Resources Investigations Report 84-4046
During the past 40 years, pumpage of ground water for irrigation from the High Plains aquifer system underlying Box Butte County, Nebraska, has resulted in a steady decline of water levels. Consequently, a digital model of the aquifer system was constructed to evaluate various water-management alternatives. The hydraulic conductivity of...
Potential effects of surface coal mining on the hydrology of the West Otter area, Ashland and Birney-Broadus coal fields, southeastern Montana
N. E. McClymonds
1984, Water-Resources Investigations Report 84-4087
Shallow aquifers exist primarily within the Tongue River Member of the Paleocene Fort Union Formation and within valley alluvium. Sandstone beds are the principal aquifers for domestic supply and livestock watering, with the Knobloch coal bed being a secondary source of supply. Surface-water resources consist principally of perennial flow in...
Statistical summaries of streamflow data in Oregon; Volume 1, eastern Oregon
John Friday, S. J. Miller
1984, Open-File Report 84-454
Statistical summaries of streamflow data at 335 streamgaging sites are presented in this two volume report to aid in appraising the hydrology of river basins in Oregon. Records for 31 gaging stations were compiled into separate periods owing to changes in regulation during the period of data collection. The periods...
Changes in flood response of the Red River of the North basin, North Dakota-Minnesota
Jeffrey E. Miller, Dale L. Frink
1984, Water Supply Paper 2243
The magnitude and frequency of large floods that have occurred in recent years in the basin of the Red River of the North have caused concern that land-use changes and manmade drainage have increased flooding. This study was undertaken to determine whether any changes in flood response of the basin...

Chemical and hydrologic assessment of the Caloosahatchee River basin, Lake Okeechobee to Franklin Lock, Florida
H. R. La Rose, B. F. McPherson
1983, Water-Resources Investigations Report 83-4126
Annual discharge (1970-79 water years) from Lake Okeechobee to the Caloosahatchee River averaged 51 percent of the total river discharge at Franklin Lock and ranged from 10 to 71 percent of total discharge. Excluding rainfall on the river surface and upstream seepage, surface and subsurface runoff from the basin accounted...
