Natural ground-water quality in Michigan, 1974-87
T. Ray Cummings
1989, Open-File Report 89-259
Wide variations occur in the chemical and physical characteristics of natural groundwaters in Michigan. Dissolved-solids concentrations range from 20 to 76,000 mg/L. Waters having low dissolved-solids concentrations are calcium bicarbonate-type waters. Sodium, sulfate, and chloride increase as mineralization increases. Iron, aluminum, and titanium concentrations are higher at some locations than...
Ground-water level data for North Carolina, 1987
Ronald W. Coble, A.G. Strickland, M. Carl Bailey
1989, Open-File Report 89-68
Continuous and periodic measurements in 54 key wells and water-level measurements emplaced in Coastal Plain aquifers across North Carolina in 193 supplemental wells are presented in this report. Hydrographs of selected wells show changes in ground-water storage in the State. The water table in the shallow aquifers was higher throughout...

Osmotic potential and projected drought tolerance of four phreatophytic shrub species in Owens Valley, California
Peter D. Dileanis, David P. Groeneveld
1989, Water Supply Paper 2370-D
A substantial quantity of the water used by plant communities growing on the floor of Owens Valley, California, is derived from a shallow unconfined aquifer. Fluctuations in the water table caused by ground-water withdrawal may result in periods when this water supply is not accessible to plants. The capacity of...
Triassic-Jurassic stratigraphy of the Culpeper and Barboursville basins, Virginia and Maryland
K. Y. Lee, A.J. Froelich
1989, Professional Paper 1472
The presence of Late Triassic and Early Jurassic spores and pollen throughout an exposed stratigraphic section has enabled the systematic palynofloral zonation of the entire Culpeper Group, supported in places by characteristic fish zones. Strata of the Culpeper Group range in age from the Late Triassic to the Early Jurassic....
Estimating soil matric potential in Owens Valley, California
Stephen K. Sorenson, Reuben F. Miller, Michael R. Welch, David P. Groeneveld, Farrel A. Branson
1989, Water Supply Paper 2370-C
Much of the floor of Owens Valley, California, is covered with alkaline scrub and alkaline meadow plant communities, whose existence is dependent partly on precipitation and partly on water infiltrated into the rooting zone from the shallow water table. The extent to which these plant communities are capable of adapting...
Selected hydrologic data for Fountain Creek and Monument Creek basins, east-central Colorado
Gerhard Kuhn, Roderick F. Ortiz
1989, Open-File Report 88-705
Selected hydrologic data were collected during 1986, 1987, and 1988 by the U.S. Geological Survey for the Fountain Creek and Monument Creek basins, east-central Colorado. The data were obtained as part of a study to determine the present and projected effects of wastewater discharges on the two creeks. The data,...
