Geological and borehole geophysical data and observations collected to characterize the basin and its surface and groundwater flow systems with primary focus on the physical characteristics of the fault vein, related mine workings, and surrounding bedrock
Preliminary information about the concentration, spatial distribution and mineral hosting of metals and other elements in solid materials at the Elizabeth copper mine after 50 years (or more) of weathering and oxidation.
A multidisciplinary mapping and data integration project focused on long-term resource planning by the mapping and characterization of exposed surface mineralogy, including that related to hydrothermal alteration and supergene weathering of pyritic rocks.
Water quality data for the area include pH, dissolved oxygen, alkalinity, total acid soluble and dissolved major and trace element concentrations for sites around the mine workings.
Data from a study intended to explore how well the chemical analysis of water and sediment in an area reflects that of the rock from which the sediments are eroded and through which the water flows.
This report presents chemical characteristics of transient unsaturated-zone water collected by lysimeter from the Manning Canyon repository site in Utah. Data collected by U.S. Geological Survey and U.S. Department of the Interior, Bureau of Land Manageme
Study focusing on the effects of historical mining on Forest Service lands in this area.
This report releases data for waters in which naturally occurring acid-rock drainage occurs but acid-mine drainage from historical mining continues to contribute dissolved metals further degrading preexisting water quality.
One hundred years of historical mining has resulted in substantial ongoing input of cadmium, lead, and zinc into the environment. This surficial-soil sampling and coring study provides information needed to support remediation efforts.
Presents data and describes the methods used to determine the physical attributes, as well as the chemical and mineralogical composition of surficial deposits; groundwater levels; and water composition in this area.
Periodic sampling of water during the spring of 2010 was carried out to understand the range and timing of variation in pH and metal concentration, and help evaluate variation in water quality during spring runoff.
This report is a compilation of water and sediment chemical data generated by the USGS study of indigenous, arsenic-sequestering microbial communities. A total of 9 synoptic sampling efforts conducted at specific sites are described.
