2001, Open-File Report 2001-71
A laboratory for analysis of low-ionic strength water has been developed at the U.S. Geological Survey (USGS) office in Troy, N.Y., to analyze samples collected by USGS projects in the Northeast. The laboratory's quality-assurance program is based on internal and interlaboratory quality-assurance samples and quality-control procedures developed to ensure proper...
Estimation of hydraulic characteristics in the Santa Fe Group aquifer system using computer simulations of river and drain pulses in the Rio Bravo study area, near Albuquerque, New Mexico
D.M. Roark
2001, Water-Resources Investigations Report 2001-4069
In 1997, the U.S. Geological Survey conducted a hydrologic investigation of the surface-water/ground-water interaction of the Rio Grande and the surrounding alluvium and the Santa Fe Group aquifer system in an area near the Rio Bravo Bridge, south of Albu- querque, New Mexico. A set of existing wells and new wells...

Deep regional resistivity structure across the Battle Mountain-Eureka and Carlin trends, north-central Nevada
Brian D. Rodriguez, Jackie M. Williams
2001, Open-File Report 2001-346
Magnetotelluric data collected along four, regional scale, southwest-to-northeast profiles show deep resistivity structures beneath the Battle Mountain-Eureka and Carlin gold trends in north-central Nevada, which appear consistent with tectonic breaks in the crust that possibly served as channels for hydrothermal fluids. It seems likely that gold deposits along these linear...

Potentiometric surface, carbonate-rock province, southern Nevada and southeastern California, 1998-2000
J.W. Wilson
2001, Open-File Report 2001-335
The carbonate-rock aquifer that underlies most of southern Nevada occupies part of what is known as the carbonate-rock province, a physiographic region that encompasses the eastern two-thirds of the Great Basin. The potential for development of water resources in this aquifer has prompted Federal, State, and local authorities to seek...

Manganese recycling in the United States in 1998
Thomas S. Jones
2001, Open-File Report 2001-304
This report describes the flow and processing of manganese within the U.S. economy in 1998 with emphasis on the extent to which manganese is recycled. Manganese was used mostly as an alloying agent in alloys in which it was a minor component. Manganese was recycled mostly within scrap of iron...
Hydrogeologic characterization of the Coldwater Spring recharge area, Calhoun County, Alabama
Robert E. Kidd
2001, Open-File Report 2001-300
The complex ground-water flow in the Coldwater Spring aquifer system is the result of complicated geologic structures, porous media flow within the shallow unconsolidated zone, conduit flow in the karst bedrock aquifers, and discontinuities in hydrogeologic units caused by faulting. Recharge water in the unconsolidated zone percolates slowly to the...
