Comparison, analysis, and estimation of discharge data from two acoustic velocity meters on the Chicago Sanitary and Ship Canal at Romeoville, Illinois
Charles S. Melching, Kevin A. Oberg
1993, Water-Resources Investigations Report 93-4048
The acoustic velocity meter (AVM) on the Chicago Sanitary and Ship Canal (the Canal) at Romeoville, Ill., provides vital information for the accounting of the diversion of water from Lake Michigan. A detailed analysis of the discharge record on the Canal at Romeoville was done by the U.S. Geological...
Reconnaissance investigation of the geology and hydrogeology of Lackland Air Force Base, San Antonio, Texas
G. B. Ozuna, T. A. Small
1993, Water-Resources Investigations Report 93-4037
An investigation at Lackland Air Force Base and Lackland Air Force Base Training Annex (Medina Base) was conducted from May to September 1988 to delineate the subsurface geology, to describe the hydrogeology within the study area, and to determine possible migration pathways for contaminants. Data from this investigation supplement data...
Integrated mineral-resource and mineral-environmental assessments of public lands: Applications for land management and resource planning
Geoffrey S. Plumlee, Steven M. Smith, Margo I. Toth, Sherman P. Marsh, S. D. Ludington, A. R. Wallace, W. H. Ficklin, K. S. Smith, J. T. Nash, N.K. Foley, R. E. Van Loenen, B. R. Berger, G. Green
1993, Open-File Report 93-571
Mineral-deposit geology is an important control on natural contamination from unmined mineral deposits, and on the environmental effects of mining and mineral processing. The U. S. Geological Survey, Office of Mineral Resources (USGS/OMR) is now integrating geology-based environmental assessments into its mineral resource assessments of public and other lands. This report presents...
Estimated average annual ground-water pumpage in the Portland Basin, Oregon and Washington 1987-88
C. A. Collins, T.M. Broad
1993, Water-Resources Investigations Report 91-4018
Data for ground-water pumpage were collected during an inventory of wells in 1987-88 in the Portland Basin located in northwestern Oregon and southwestern Washington. Estimates of annual ground-water pumpage were made for the three major categories of use: public supply, industry, and irrigation. A large rapidly expanding metropolitan area is...
Quaternary geologic map of the Sudbury 4° x 6° quadrangle, United States and Canada
David S. Fullerton, Edward V. Sado, C. L. Baker, William R. Farrand
1993, IMAP 1420(NL-17)
The Quaternary Geologic Map of the Sudbury 4° x 6° quadrangle was mapped as part of the Quaternary Geologic Atlas of the United States. The atlas was begun as an effort to depict the areal distribution of surficial geologic deposits and other materials that accumulated or formed during the past...
Understanding our fragile environment; Lessons from geochemical studies
Larry P. Gough, Sigrid Asher-Bolinder, Laurie S. Balistrieri, George N. Breit, Thomas J. Casadevall, James G. Crock, Kimberley I. Cunningham, Joseph S. Duval, James A. Erdman, Barbara M. Erickson, Walter H. Ficklin, Larry L. Jackson, Rama K. Kotra, Joel S. Leventhal, James M. McNeal, William R. Miller, James K. Otton, Douglass E. Owen, Geoffrey S. Plumlee, G. Michael Reimer, Ronald C. Severson, Kathleen S. Smith, Ronald R. Tidball, Robert A. Zielinski
1993, Circular 1105
An understanding of our fragile environment can begin with a recognition of the importance of certain elements, commonly called "minerals substances" (such as iron and zinc), in the lives of humans and animals and in the soils that support plants. This recognition is well deserved because these elements are essential...
Potentiometric surface of the upper Patapsco Aquifer in southern Maryland, September 1991
Stephen E. Curtin, D. C. Andreasen, Frederick K. Mack
1993, Open-File Report 93-654
A map showing the potentiometric surface of the upper Patapsco aquifer in the Patapsco Formation of Cretaceous age in southern Maryland during September 1991 was prepared from water levels measured in wells. The potentiometric surface was at least 70 feet above sea level near the northwestern boundary and outcrop area...
