Assessment of the potential for biodegradation of petroleum hydrocarbons in the Railroad Industrial Area, Fairbanks, Alaska
Joan F. Braddock, Peter H. Catterall, Sharon A. Richmond
1998, Open-File Report 98-287
Many technologies for the clean-up of petroleum-hydrocarbon contaminated sites depend on microbial degradation of the pollutant. In these technologies the site may be modified to enhance microbial activity, or may simply be monitored for naturally occurring microbial activity. In either case, an important aspect of site assessment for these technologies...
Ground-water quality in three urban areas in the Coastal Plain of the southeastern United States, 1995
M. P. Berndt, D.R. Galeone, T.B. Spruill, C. A. Crandall
1998, Water-Resources Investigations Report 97-4234
Ground-water quality is generally good in three urban areas studied in the Coastal Plain of the southeastern United States涌cala and Tampa, Florida, and Virginia Beach, Virginia. The hydrology of these areas differs in that Ocala has many karst depressions but virtually no surface-water features, and Tampa and Virginia Beach have...
Digital Geologic Map of the Rosalia 1:100,000 Quadrangle, Washington and Idaho: A Digital Database for the 1990 S.Z. Waggoner Map
Pamela D. Derkey, Bruce R. Johnson, Beatrice B. Lackaff, Robert E. Derkey
1998, Open-File Report 98-357
The geologic map of the Rosalia 1:100,000-scale quadrangle was compiled in 1990 by S.Z. Waggoner of the Washington state Division of Geology and Earth Resources. This data was entered into a geographic information system (GIS) as part of a larger effort to create regional digital geology for the Pacific Northwest....
Front Range Infrastructure Resources Project: water-resources activities
Stanley G. Robson, Janet S. Heiny
1998, Fact Sheet 113-98
Infrastructure, such as roads, buildings, airports, and dams, is built and maintained by use of large quantities of natural resources such as aggregate (sand and gravel), energy, and water. As urban area expand, local sources of these resource are becoming inaccessible (gravel cannot be mined from under a subdivision, for...
Digital map of base of aquifer for High Plains Aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
Joel R. Cederstrand, Mark F. Becker
1998, Open-File Report 98-393
This report contains digital data and accompanying documentation for base of aquifer contours of the High Plains aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The original data are from the 1:1,000,000-scale mylar source map for Gutentag and others (1984)....
Geology and mineral resources of the Lake Valley area, Sierra County, New Mexico
C.J. Nutt, J.M. O’Neill, V. T. McLemore, David A. Lindsey, J.C. Ratte, D. C. Hedlund, D. P. Klein, M. D. Kleinkopf
1998, Open-File Report 98-347
At the request of the Bureau of Land Management, the U.S. Geological Survey assessed the Lake Valley Area of Critical Environmental Concern (ACEC), which includes the historic Lake Valley townsite and silver-manganese mining district, for undiscovered mineral resources. The Lake Valley ACEC is along the southeastern margin of the Black...
Ground-water flow analysis of the Mississippi Embayment aquifer system, South-Central United States
J. K. Arthur, R.E. Taylor
1998, Professional Paper 1416-I
The Mississippi Embayment aquifer system is composed of six regional aquifers covering about 160,000 square miles in parts of Alabama, Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, and Tennessee. The flow analysis presented in this report as part of the Gulf Coast Regional Aquifer-System Analysis study pertains to five aquifers in...
Digital map of specific yield for the High Plains Aquifer in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
J. R. Cederstrand, M.F. Becker
1998, Open-File Report 98-414
This digital data set consists of specific yield percentage contours and polygons for the High Plains aquifer in the central United States. The High Plains aquifer extends from south of 32 degrees to almost 44 degrees north latitude and from 96 degrees 30 minutes to almost 106 degrees west longitude....
Ground-water flow in the surficial aquifer system and potential movement of contaminants from selected waste-disposal sites at Cecil Field Naval Air Station, Jacksonville, Florida
K. J. Halford
1998, Water-Resources Investigations Report 97-4278
As part of the Installation Restoration Program, Cecil Field Naval Air Station, Jacksonville, Florida, is considering remedialaction alternatives to control the possible movement of contaminants from sites that may discharge to the surface. This requires a quantifiable understanding of ground-water flow through the surficial aquifer system and how the system...
Local tsunamis and earthquake source parameters
Eric L. Geist
Renata Dmowska, Barry Saltzman, editor(s)
1998, Book chapter, Advances in geophysics
This chapter establishes the relationship among earthquake source parameters and the generation, propagation, and run-up of local tsunamis. In general terms, displacement of the seafloor during the earthquake rupture is modeled using the elastic dislocation theory for which the displacement field is dependent on the slip distribution, fault geometry, and...
