Estimated water withdrawals and use in Illinois, 1992
Charles Avery
1999, Open-File Report 99-97
The total amount of water withdrawn in Illinois during 1992 was about 19,076 (Mgal/d) million gallons per day. About 16,101 Mgal/d, or about 84 percent of this total, was withdrawn for thermoelectric-power generation, and about 1,877 Mgal/d was withdrawn by and delivered from public-supply facilities. About 1,910 Mgal/d of surface...
Concentrations of fecal coliform bacteria in creeks, Anchorage, Alaska, August and September 1998
Joseph M. Dorava, Andra Love
1999, Open-File Report 99-236
Water samples were collected from five creeks in undeveloped, semi-developed, and developed areas of Anchorage, Alaska, during August and September 1998 to determine concentrations of fecal coliform bacteria. In undeveloped areas of Ship, Chester, and Campbell Creeks, and the semi-developed area of Rabbit Creek, concentrations of fecal coliform bacteria ranged...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of dissolved arsenic, boron, lithium, selenium, strontium, thallium, and vanadium using inductively coupled plasma-mass spectrometry
John R. Garbarino
1999, Open-File Report 99-93
The inductively coupled plasma-mass spectrometric (ICP-MS) methods have been expanded to include the determination of dissolved arsenic, boron, lithium, selenium, strontium, thallium, and vanadium in filtered, acidified natural water. Method detection limits for these elements are now 10 to 200 times lower than by former U.S. Geological Survey (USGS) methods,...
A seismic-reflection investigation of gas hydrates and sea-floor features of the upper continental slope of the Garden Banks and Green Canyon regions, northern Gulf of Mexico: report for cruise G1-99-GM (99002)
Alan Cooper, David Twichell, Patrick Hart
1999, Open-File Report 99-570
During April 1999, the U.S. Geological Survey (USGS) conducted a 13-day cruise in the Garden Banks and Green Canyon regions of the Gulf of Mexico. The R/V Gyre, owned by Texas A&M University, was chartered for the cruise. The general objectives were (1) to acquire very high resolution seismic-reflection data...
Rock-fall potential in the Yosemite Valley, California
Gerald F. Wieczorek, Meghan M. Morrissey, Giulio Iovine, Jonathan W. Godt
1999, Open-File Report 99-578
We used two methods of estimating rock-fall potential in the Yosemite Valley, California based on (1) physical evidence of previous rock-fall travel, in which the potential extends to the base of the talus, and (2) theoretical potential energy considerations, in which the potential can extend beyond the base of the...
Water use in Arkansas, 1995
Terrance W. Holland
1999, Open-File Report 99-188
As part of the National Water-Use Information Program, the U.S. Geological Survey (USGS) stores water-use data in standardized format for different categories of water use. These data are aggregated by county, 4- and 8-digit hydrologic units, and aquifer in the Aggregated Water-Use Data System (AWUDS). Site-specific water-use data for public...
Water-level altitudes 1999, water-level changes 1977-99 and 1998-99, and compaction 1973-98 in the Chicot and Evangeline aquifers: Houston-Galveston region, Texas
L.S. Coplin, H. X. Santos, J. W. East
1999, Open-File Report 99-178
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1977 and compaction since 1973 in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. The report, prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District,...
Geochemical data for stream-sediment, heavy-mineral-concentrate, and rock samples collected from the Fortyseven Creek gold-arsenic-antimony-tungsten prospect, southwestern Alaska
John E. Gray, G. K. Lee, R. M. O’Leary, P. M. Theodorakos
1999, Open-File Report 99-584
In the summer of 1991, we conducted a reconnaissance geochemical survey around the Fortyseven Creek Au-As-Sb-W prospect that is located in the southwestern part of the Sleetmute quadrangle. At that time, this project was a small part of a more comprehensive Alaska Mineral Resource Assessment Program (AMRAP) study of the...
Physical, chemical, and isotopic data for samples from the Anderson Springs area, Lake County, California, 1998-1999
C. J. Janik, F. Goff, M.L. Sorey, J. J. Rytuba, D. Counce, E.M. Colvard, M. Huebner, L. D. White, A. Foster
1999, Open-File Report 99-585
Anderson Springs is located about 90 miles (145 kilometers) north of San Francisco, California, in the southwestern part of Lake County. The area was first developed in the late 1800s as a health resort, which was active until the 1930s. In the rugged hills to the south of the resort...
