Geochemical data from analyses of rock, sediment, water, and solid-phase leaching at the Tuba City Open Dump, Tuba City, Arizona
This report releases data collected by the U.S. Geological Survey from the Tuba City Open Dump area from January 2008 to September 2008 with cooperation from the U.S. Bureau of Indian Affairs and the Navajo and Hopi Tribes. These data were collected in support of investigations into the possible sources and resulting transport of radionuclides and other dissolved constituents in the surrounding gr

Preliminary geophysical characterization of two oil production sites, Osage County, Oklahoma - Osage Skiatook Petroleum Environmental Research Project
Ground electromagnetic and dc resistivity geophysical surveys were used to interpret the subsurface distribution of salinized soil, water, and bedrock at two sites (A and B) and to characterize the larger scale hydrologic setting. Measurements were made on grids of about 1000 square meters using a very shallow penetrating (less than 10 m) electromagnetic (EM) geophysical system (EM31). At site A,

Graphs and tables used to describe electrical measurements of samples of unconsolidated materials, USGS Petrophysical Laboratory, Denver
The U.S. Geological Survey Petrophysical Laboratory (PetLab) in Denver CO measures electrical properties of samples of earth materials collected by U.S. Geological Survey personnel. This report describes the standard graphs and tables produced by PetLab to present geoelectrical measurements made on samples of unconsolidated materials.

Tests of ground-penetrating radar and induced polarization for mapping fluvial mine tailings on the floor of the Couer d'Alene River, Idaho
In order to investigate sequences of toxic mine tailings that have settled in the bed of the Coeur d'Alene River, Idaho, (see figure 1) we improvised ways to make geophysical measurements on the river floor. To make ground penetrating radar (GPR) profiles, we mounted borehole antennas on a skid that was towed along the river bottom. To make induced polarization (IP) profiles, we devised a bottom s

Landfill mapping using multi-disciplinary geophysical techniques at the U.S. Air Force Academy, Colorado Springs, CO
This paper describes a multi-disciplinary geophysical survey conducted over a
landfill on the U.S. Air Force Academy grounds near Colorado Springs, Colorado.
The landfill is known to contain waste generated during the construction of the
Academy and reportedly contains buried steel drums. The purpose of the
geophysical surveys was to determine the subsurface distribution of buried
metallic objects
