Geohydrology of the northern part of the town of Brookhaven, Suffolk County, New York
E. J. Koszalka
1984, Water-Resources Investigations Report 83-4042
In general, ground water in the area is of suitable quality for drinking and most other uses. Some constituents, however, particularly iron, chloride, and nitrogen, occur locally in unacceptable concentrations. Average hydraulic conductivity ranges from 100 to 300 feet per day (ft/d) in the upper glacial aquifer and from 50...
The thrust belt in Southwest Montana and east-central Idaho
Edward T. Ruppel, David A. Lopez
1984, Professional Paper 1278
The leading edge of the Cordilleran fold and thrust in southwest Montana appears to be a continuation of the edge of the Wyoming thrust belt, projected northward beneath the Snake River Plain. Trces of the thrust faults that form the leading edge of the thrust belts are mostly concealed, but...
Igneous activity and related ore deposits in the western and southern Tushar Mountains, Marysvale volcanic field, west-central Utah
Thomas A. Steven, editor(s)
1984, Professional Paper 1299-A,B
PART A: Igneous activity in the Marysvale volcanic field of western Utah can be separated into many episodes of extrusion, intrusion, and hydrothermal activity. The rocks of the western Tushar Mountains, near the western part of the volcanic field, include intermediate-composition, calc-alkalic volcanic rocks erupted from scattered volcanoes in Oligocene...
Hydrogeology of the Verna well-field area and management alternatives for improving yield and quality of water, Sarasota County, Florida
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4006
About 8 million gallons of water are pumped daily from the 3-square-mile Verna well field to supply the city of Sarasota. Pumping has resulted in water-level declines and changes in water quality. Drawdowns of at least 30 feet have occurred in the producing zone at the well-field boundaries. Sulfate concentrations...
A statistical approach to evaluate the relation of coal mining, land reclamation, and surface-water quality in Ohio
Janet Hren, K. S. Wilson, D.R. Helsel
1984, Water-Resources Investigations Report 84-4117
Base-flow data from 779 sites in Ohio 's coal region were analyzed statistically to relate land use to selected water-quality characteristics. Sites were classified into five categories: unmined (100 percent unmined land), abandoned (50 percent or more abandoned surface mines), reclaimed (50 percent or more reclaimed surface mines), deep-mined (50...
Glastonbury Gneiss and mantling rocks (a modified Oliverian dome) in south-central Massachusetts and north-central Connecticut: Geochemistry, petrogenesis, and isotopic age
G. W. Leo, R. E. Zartman, D. G. Brookins
1984, Professional Paper 1295
The Glastonbury dome is a long, narrow structure trending approximately 70 km north-northeast through Connecticut and Massachusetts along the west side of the Bronson Hill anticlinorium. Structurally and stratigraphically the dome is analogous to the Oliverian domes of New Hampshire. It is cored by Glastonbury Gneiss and is mantled by...
Earth and water resources and hazards in Central America
Charles G. Cunningham, R.W. Fary, Marianne Guffanti, Della Laura, M. P. Lee, C.D. Masters, R. L. Miller, Ferdinand Quinones-Marquez, R.W. Peebles, J.A. Reinemund, D. P. Russ
1984, Circular 925
Long-range economic development in Central America will depend in large part on production of indigenous mineral, energy, and water resources and on mitigation of the disastrous effects of geologic and hydrologic hazards such as landslides, earthquakes, volcanic eruptions, and floods. The region has six world-class metal mines at present as...
Leaching study of oil shale in Kentucky: With a section on hydrologic reconnaissance of the oil shale outcrop in Kentucky
Samuel S. Leung, D.W. Leist, R. W. Davis, Steven Cordiviola
1984, Water-Resources Investigations Report 84-4073
Oil shales in Kentucky are rocks of predominantly Devonian age. The most prominant are the Ohio, Chattanooga, and New Albany Shales. A leaching study was done on six fresh oil shale samples and one retorted oil shale sample. Leaching reagents were distilled water, 0.0005 N sulfuric acid, and 0.05 N...
