Analytical results for 35 mine-waste tailings cores and six bed sediment samples, and an estimate of the volume of contaminated materials at Buckeye meadow on upper Basin Creek, northern Jefferson County, Montana
Metal-mining related wastes in the Boulder River basin study area in northern Jefferson County, Montana have been implicated in their detrimental effects on water quality with regard to acid-generation and toxic-metal solubilization. Flotation-mill tailings in the meadow below the Buckeye mine, hereafter referred to as the Buckeye mill-tailings site, have been identified as significant contributor

pick_xwell, a program for interactive picking of crosswell seismic and radar data
Program 'pick_xwell' is used to interactively pick travel times in
crosswell seismic and radar data. In addition, the traces and the
travel times can be plotted on the computer screen or printed to a
file in postscript format. The program is written in the IDL
programming language, and it is executed, in command-line mode, within
the IDL program. The IDL program must be run from an X-window

Upgrade to MODFLOW-GUI; addition of MODPATH, ZONEBDGT, and additional MODFLOW packages to the U.S. Geological Survey MODFLOW-96 Graphical-User Interface
This report describes enhancements to a Graphical-User Interface (GUI) for MODFLOW-96, the U.S. Geological Survey (USGS) modular, three-dimensional, finitedifference ground-water flow model, and MOC3D, the USGS three-dimensional, method-ofcharacteristics solute-transport model. The GUI is a plug-in extension (PIE) for the commercial program Argus ONEe. The GUI has been modified to support MODPATH

Ground-water resources of Kings and Queens counties, Long Island, New York
From 1981 through 1986, the U.S. Geological Survey investigated the ground-water system of western Long Island, New York, including Kings and Queens counties. This report describes the structure and operation of the western part of the Long Island ground-water system, and the hydrologic effects associated with human development from 1900 to the early 1980's. Recent (early 1980's) ground-water quan

Quantification of metal loading in Fisher Creek by tracer injection and synoptic sampling, Park County, Montana, August 1997
Acid mine drainage from abandoned and inactive mines affects the water quality of the upper reaches of Fisher Creek, Montana. A sodium chloride tracer was added to the stream for 29.5 hours to provide a hydrologic context for synoptic sampling of metal chemistry in the stream and its inflows. The detailed profile of stream discharge obtained from the sampling helped to indicate those areas of Fish

Simulation of the effects of development of the ground-water flow system of Long Island, New York
Extensive development on Long Island since the late 19th century and projections of increased urbanization and ground-water use makes effective water-resource management essential for preservation of the island's hydrologic environment and maintenance of a reliable source of water supply. This report presents results of a ground-water flow simulation analysis of the effects of development on the L

Geohydrology of monitoring wells drilled in Oasis Valley near Beatty, Nye County, Nevada, 1997
Twelve monitoring wells were installed in 1997 at seven sites in and near Oasis Valley, Nevada. The wells, ranging in depth from 65 to 642 feet, were installed to measure water levels and to collect water-quality samples. Well-construction data and geologic and geophysical logs are presented in this report. Seven geologic units were identified and described from samples collected during the drilli

U.S. Geological Survey Toxic Substances Hydrology Program: Proceedings of the technical meeting, Charleston, South Carolina, March 8-12, 1999: Volume 2 (Part B)
This report contains papers presented at the seventh Technical Meeting of the U.S. Geological Survey (USGS), Toxic Substances Hydrology (Toxics) Program. The meeting was held March 8-12, 1999, in Charleston, South Carolina. Toxics Program Technical Meetings are held periodically to provide a forum for presentation and discussion of results of recent research activities.The objectives of these meet
