Water resources activities in Illinois, 1985
M. L. Garrelts
1986, Open-File Report 86-130
This report gives an overview of U.S. Geological Survey, Illinois District, Water Resources Division activities related to the water resources of the State of Illinois. The report includes sections describing District organization, programs, water conditions, data collection activities, and project summaries. Also included is a complete listing of District and...
Quantity and quality of urban storm runoff in the Irondequoit Creek basin near Rochester, New York: Part 2,.Quality of storm runoff and atmospheric deposition, rainfall-runoff-quality modeling and potential of wetlands for sediment and nutrient retention
W. M. Kappel, R. M. Yager, Philip J. Zarriello
1986, Water-Resources Investigations Report 85-4113
Water quality data collected at 17 sites in urbanized and rural parts of the 438 sq km Irondequoit Creek basin from July 1980 through August 1981 were used to compute annual loads of eight selected constituents. Of the total annual loads of these constituents, 50 to 70% was transported to...
Benthic invertebrate population characteristics as affected by water quality in coal-bearing regions of Tennessee
A.D. Bradfield
1986, Water-Resources Investigations Report 85-4227
Benthic invertebrate and water quality data collected during previous U.S. Geological Survey studies to provide background hydrologic information on streams draining Tennessee coal reserves, were evaluated to identify possible relations between stream biota and water quality. Linear regressions produced low correlation coefficients relating the number of taxa/sample, total number of...
A description of the hydrologic system and the effects of coal mining on water quality in the East Fork Little Chariton River and the alluvial aquifer between Macon and Huntsville, north-central Missouri
D. C. Hall
1986, Water-Resources Investigations Report 86-4160
The quality of surface and groundwater has been affected by abandoned strip mines and by abandoned underground mines in a 110-sq mi subbasin of the East Fork Little Chariton River. More than 14% of the area was strip mined for coal before 1979. The hydrologic system in the area was...
The SALT NORM : a quantitative chemical-mineralogical characterization of natural waters
Marc W. Bodine Jr., Blair F. Jones
1986, Water-Resources Investigations Report 86-4086
The new computer program SNORM calculates the salt norm from the chemical composition of a natural water. The salt norm is the quantitative ideal equilibrium assemblage that would crystallize if the water evaporated to dryness at 25 C and 1 bar pressure under atmospheric partial pressure of CO2. SNORM proportions...
Exploration for areas suitable for ground-water development, central Connecticut Valley lowlands, Massachusetts
B. P. Hansen
1986, Water-Resources Investigations Report 84-4106
Drilling and geophysical borehole logs for a 25-sq-mi section of the Connecticut River valley lowlands area of Amherst, Hadley, and Sunderland, Massachusetts, indicate that the area is mostly underlain by fine-grained lacustrine deposits. Nine test wells ranging in depth from 100 to 303 ft completely penetrate the unconsolidated valley fill....
Climatic data for Mirror Lake, West Thornton, New Hampshire, 1984
A.M. Sturrock, D.C. Buso, J.L. Scarborough, T. C. Winter
1986, Open-File Report 86-134
Research on the hydrology of Mirror lake, (north-central) New Hampshire includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: temperature of lake water surface; dry-bulb and wet-bulb air temperatures; wind speed at 3 levels above the water surface; and solar and atmospheric...
Quality-assurance results for field pH and specific-conductance measurements, and for laboratory analysis, National Atmospheric Deposition Program and National Trends Network; January 1980-September 1984
L.J. Schroder, M. H. Brooks, B.A. Malo, T. C. Willoughby
1986, Water-Resources Investigations Report 86-4139
Five intersite comparison studies for the field determination of pH and specific conductance, using simulated-precipitation samples, were conducted by the U.S.G.S. for the National Atmospheric Deposition Program and National Trends Network. These comparisons were performed to estimate the precision of pH and specific conductance determinations made by sampling-site operators. Simulated-precipitation...
Water resources of Hughes County, South Dakota
L.J. Hamilton
1986, Water-Resources Investigations Report 84-4195
Three major glacial-drift aquifers consisting of outwash sand and gravel underlie Hughes County, 784 sq mi of plains incised by the outwash-filled valley of the Missouri River in central South Dakota. Glacial-drift aquifers are recharged by more than 9,000 acre-feet of water annually and store about 1 million acre-feet of...
