Results of the U.S. Geological Survey's Analytical Evaluation Program for Standard Reference Samples Distributed in March 2000
Jerry W. Farrar, Ashley M. Copen
2000, Open-File Report 2000-398
This report presents the results of the U.S. Geological Survey's analytical evaluation program for six standard reference samples -- T-161 (trace constituents), M-154 (major constituents), N-65 (nutrient constituents), N-66 nutrient constituents), P-34 (low ionic strength constituents), and Hg-30 (mercury) -- that were distributed in March 2000 to 144 laboratories enrolled...
MODFLOW-2000, the U.S. Geological Survey Modular Ground-Water Model -Documentation of the Hydrogeologic-Unit Flow (HUF) Package
E.R. Anderman, M. C. Hill
2000, Open-File Report 2000-342
This report documents the Hydrogeologic-Unit Flow (HUF) Package for the groundwater modeling computer program MODFLOW-2000. The HUF Package is an alternative internal flow package that allows the vertical geometry of the system hydrogeology to be defined explicitly within the model using hydrogeologic units that can be different than the definition of the model layers....
Preliminary volcano-hazard assessment for the Katmai volcanic cluster, Alaska
Judy Fierstein, Wes Hildreth
2000, Open-File Report 2000-489
The world’s largest volcanic eruption of the 20th century broke out at Novarupta (fig. 1) in June 1912, filling with hot ash what came to be called the Valley of Ten Thousand Smokes and spreading downwind more fallout than all other historical Alaskan eruptions combined. Although almost all the magma...
Water-surface profile and flood boundaries for the computed 100-year flood, lower Salt River, Lincoln County, Wyoming
Kirk A. Miller, John P. Mason
2000, Open-File Report 2000-201
The water-surface profile and flood boundaries for the computed 100-year flood were determined for a part of the lower Salt River in Lincoln County, Wyoming. Channel cross-section data were provided by Lincoln County. Cross-section data for bridges and other structures were collected and compiled by the U.S. Geological Survey. Roughness...

Christopher A. Sanocki, Thomas A. Winterstein
2000, Open-File Report 99-472
Data that describe the physical characteristics of stream subbasins upstream from selected sites on streams in the Cannon River Basin, located in southeastern Minnesota, are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin covered only by lakes, the...
Evaluation of the Federal-State Cooperative observation well network in upstate New York, 1995-97
Richard J. Reynolds
2000, Open-File Report 99-468
The U.S. Geological Survey?s Federal-State cooperative observation well network in upstate New York was evaluated in terms of areal coverage, objectives, and short- and long-term expansion plans. This report presents a history of the observation well network in upstate New York and depicts, on maps, the distribution of observation wells with respect to climatic regions, physiographic regions,...
Method for estimating pesticide use for county areas of the conterminous United States
Gail P. Thelin, Leonard P. Gianessi
2000, Open-File Report 2000–0250
Information on the amount and distribution of pesticide compounds used throughout the United States is essential to evaluate the relation between water quality and pesticide use. This information is the basis of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program studies of the effects of pesticides on water quality...
Bedrock Geology of the Turkey Creek Drainage Basin, Jefferson County, Colorado
Stephen J. Char
2000, Open-File Report 2000-265
This geospatial data set describes bedrock geology of the Turkey Creek drainage basin in Jefferson County, Colorado. It was digitized from maps of fault locations and geologic map units based on age and lithology. Created for use in the Jefferson County Mountain Ground-Water Resources Study, it is to be...
Report for explosion and earthquake data acquired in the 1999 Seismic Hazards Investigation of Puget Sound (SHIPS), Washington
Thomas M. Brocher, Thomas L. Pratt, Kate C. Miller, Anne M. Trehu, Catherine M. Snelson, Craig S. Weaver, Ken C. Creager, Robert S. Crosson, Uri S. ten Brink, Marcos G. Alvarez, Steven H. Harder, Isa Asudeh
2000, Open-File Report 2000-318
This report describes the acquisition, processing, and quality of seismic reflection and refraction data obtained in the Seattle basin, central Puget Lowland, western Washington, in September 1999 during the Seismic Hazards Investigation of Puget Sound (SHIPS). As a sequel to the 1998 SHIPS air gun experiment (also known as 'Wet...
Distribution of a suite of elements including arsenic and mercury in Alabama coal
Martin B. Goldhaber, R. C. Bigelow, J. R. Hatch, J.C. Pashin
2000, Miscellaneous Field Studies Map 2333
Arsenic and other elements are unusually abundant in Alabama coal. This conclusion is based on chemical analyses of coal in the U.S. Geological Survey's National Coal Resources Data System (NCRDS; Bragg and others, 1994). According to NCRDS data, the average concentration of arsenic in Alabama coal (72 ppm) is three...
Ground-water, surface-water, and water-chemistry data, Black Mesa area, northeastern Arizona: 1998
Margot Truini, Bradley M. Baum, Gregory R. Littin, Gayl Shingoitewa-Honanie
2000, Open-File Report 2000-66
The Black Mesa monitoring program is designed to document long-term effects of ground-water pumping from the N aquifer by industrial and municipal users. The N aquifer is the major source of water in the 5,400-square-mile Black Mesa area, and the ground water occurs under confined and unconfined conditions. Monitoring activities...
