Hydrologic environments and water-quality characteristics at four landfills in Mecklenburg County, North Carolina, 1980-86
A.P. Cardinell, C.R. Barnes, W.H. Eddins, R. W. Coble
1989, Water-Resources Investigations Report 89-4035
A water-quality study was conducted during 1980-86 at four landfills in Mecklenburg County, North Carolina. Each landfill has a three-layered hydrogeologic system typical of the Piedmont, consisting of (1) the regolith; (2) a transition zone; and (3) unweathered, fractured crystalline bedrock. As much as 7.6 inches per year of rainfall...
Lithology, thickness, and extent of hydrogeologic units underlying the East Portland area, Oregon
S.V. Hartford, W. D. McFarland
1989, Water-Resources Investigations Report 88-4110
The lithology, thickness, and extent of eight distinct hydrogeologic units are described and mapped within the East Portland area of Oregon. The thickness, extent, and top of each unit are shown on contour maps at scales of 1:24,000. Their stratigraphic relations are displayed on a diagrammatic cross section. The geologic...
Corrosive ground water in the Kirkwood-Cohansey aquifer system in the vicinity of Ocean County, east-central New Jersey
George R. Kish, Julia L. Barringer, Randy L. Ulery
1989, Water-Resources Investigations Report 87-4181
Corrosive groundwater, which has been linked to trace-metal leaching from plumbing materials in Europe and the United States , has been identified in the Coastal Plain of New Jersey. The corrosiveness of groundwater in the Kirkwood-Cohansey aquifer system in New Jersey has been estimated by calculating values for the Aggressive...
Streamflow, specific-conductance, and temperature data for Bayou and Little Bayou Creeks near Paducah, Kentucky, August 15 and 16, 1989
R. D. Evaldi, D.L. McClain
1989, Open-File Report 89-582
Discharge, temperature, and specific conductance measurements were made August 15 and 16, 1989, at 74 main channel sites and seven flowing tributaries on Bayou and Little Bayou Creeks, Kentucky in the vicinity of the Paducah Gaseous Diffusion Plant. These measurements were made during base flow conditions to provide data for...
Aquifers in Cretaceous rocks of the central Coastal Plain of North Carolina
M. D. Winner Jr., W.L. Lyke
1989, Water-Resources Investigations Report 87-4178
Aquifers in rocks of Cretaceous age are the major source of groundwater for public supplies in the central Coastal Plain. These aquifers consist of sand, gravel, and limestone beds of the Peedee, Black Creek, and the upper and lower Cape Fear aquifers, each separated by a confining unit composed of...
Ground-water-quality assessment of the Delmarva Peninsula, Delaware, Maryland, and Virginia; analysis of available water-quality data through 1987
P. A. Hamilton, Robert J. Shedlock, P. J. Phillips
1989, Open-File Report 89-34
Regional water quality conditions were analyzed on the basis of available data for the Delmarva Peninsula. A summary of 3 Federal, 5 State, and 14 local agencies, as well as various nonprofit organizations and universities, serving as repositories for water quality data is presented. Also included is information describing the...
Summary of data pertaining to land use, rainfall, dryfall, stream discharge, and storm runoff collected as part of a study of the effects of urban runoff on Rapid Creek, Rapid City area, South Dakota
K.E. Goddard, T.K. Lockner, L.L. Harms, M.H. Smith
1989, Open-File Report 87-45
The objectives of a 3-year study of urban runoff in the Rapid City area of South Dakota were to characterize the effects of urban runoff from rainfall on the water quality of Rapid Creek, and to evaluate the effects of the runoff on the existing cold-water fishery. In order to...
Cyclic injection, storage, and withdrawal of heated water in a sandstone aquifer at St. Paul, Minnesota: Field observations, preliminary model analysis, and aquifer thermal efficiency
Robert T. Miller
1989, Open-File Report 89-261
In May 1980, the University of Minnesota began a project to evaluate the feasibility of storing heated (150 °C (degree Celsius)) water in the deep (180 to 240 m (meters)) Franconia-Ironton-Galesville aquifer and later recovering it for space heating. The Aquifer Thermal-Energy Storage (ATES) system was doublet-well design in which...
Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-89 and 1988-89, and measured compaction, 1973-89, in the Houston-Galveston region, Texas
Dana L. Barbie, L.S. Coplin, C.W. Bonnet
1989, Open-File Report 89-57
This report presents data on water-level changes in the Chinot and Evangeline aquifers during 1977-89 and 1988-89 and data on measured compaction during 1973-89. Measurements of water level in 307 wells were used to construct the maps showing water-level changes. Compaction data were obtained from 12 wells equipped with compaction monitors...
Aquifer-system compaction, Tucson Basin and Avra Valley, Arizona
R. T. Hanson
1989, Water-Resources Investigations Report 88-4172
Groundwater declines of several ft/yr since the 1940 's have induced aquifer-system compaction and land subsidence of as much as 0.5 ft in the Tucson basin and 1.1 ft in Avra Valley, Arizona. Aquifer system compaction is affected by the layering, hydraulic diffusivity, preconsolidation-stress threshold, and stress history of the...
