Plan of study for the regional aquifer systems analysis of the Michigan Basin
Richard J. Mandle
1986, Open-File Report 86-494
Quaternary glacial deposits and Pennsylvanian and Mississippian sandstones, -the Saginaw Formation and Marshall Sandstone- are the major aquifers in the Michigan basin. These aquifers supply approximately 188 million gal/day to municipalities in the 29 ,000 sq mi study area. The most significant problems related to groundwater supplies are the identification...
Aquifer model of the Susquehanna River valley in southwestern Broome County, New York
Allan D. Randall
1986, Water-Resources Investigations Report 85-4099
A finite-difference model of ground-water flow within stratified drift in the 14-mile reach of the Susquehanna River valley from Binghamton west to the Tioga County line (including Johnson City, Endicott, and Vestal) has been developed. Outwash is the most permeable and extensive type of stratified drift in the valley but...
Description and results of test-drilling program at Picatinny Arsenal, New Jersey, 1982-84
P. T. Harte, B. P. Sargent, E. F. Vowinkel
1986, Open-File Report 86-316
Picatinny Arsenal, located in north-central New Jersey, has a long history of explosives manufacturing. Past industrial activities and past waste-disposal practices have caused some groundwater contamination problems. In 1982, the U.S. Geological Survey, in cooperation with the U.S. Army, began a water resources investigation of the Arsenal. The test drilling...
Compilation and preliminary interpretation of hydrologic data for the Weldon Spring radioactive waste-disposal sites, St Charles County, Missouri — A progress report
M. J. Kleeschulte, L. F. Emmett
1986, Water-Resources Investigations Report 85-4272
The Weldon Spring Chemical Plant is located just north of the drainage divide separating the Mississippi River and the Missouri River in St. Charles County, Missouri. From 1957 to 1966 the plant converted uranium-ore concentrates and recycled scrap to pure uranium trioxide, uranium tetrafluoride, and uranium metal. Residues from these...
Velocity and surface altitude of the lower part of Hubbard Glacier, Alaska, August 1978
R. M. Krimmel, W. G. Sikonia
1986, Open-File Report 86-549
The terminus position and locations of numerous points on the lower part of Hubbard Glacier were determined from 1:58,000 scale vertical aerial photographs taken July 30, 1978 and August 23, 1978. The same surface features were located on each set of photography, allowing displacement during the time interval to be...
Availability of selected meteorological data in computer-based files of the U.S. Geological Survey, Montana, North Dakota, South Dakota, and Wyoming
Brenda L. Link, L. E. Cary
1986, Open-File Report 85-693
Meteorological data were located, acquired, and stored from selected stations in Montana and North Dakota coal regions and adjacent areas including South Dakota and Wyoming. Data that were acquired have potential use in small watershed modeling studies. Emphasis was placed on acquiring data that was collected during the period 1970...
Data on snow chemistry of the Cascade-Sierra Nevada Mountains
L.B. Laird, Howard E. Taylor, R.E. Lombard
1986, Open-File Report 86-61
Snow chemistry data were measured for solutes found in snow core samples collected from the Cascade-Sierra Nevada Mountains from late February to mid-March 1983. The data are part of a study to assess geographic variations in atmospheric deposition in Washington, Oregon, and California. The constituents and properties include pH and...
Application of seismic-refraction techniques to hydrologic studies
F.P. Haeni
1986, Open-File Report 84-746
During the past 30 years, seismic-refraction methods have been used extensively in petroleum, mineral, and engineering investigations, and to some extent for hydrologic applications. Recent advances in equipment, sound sources, and computer interpretation techniques make seismic refraction a highly effective and economical means of obtaining subsurface data in hydrologic studies....
