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.

Environmental tracer data from surface water and groundwater samples to date groundwater and define groundwater flow paths and recharge sources in Redwell Basin. Data are provided in CSV and shapefile formats.

Inorganic chemical analysis of surface- and groundwater and springs in this area to understand natural versus anthropogenic inputs from mineralized and hydrothermally altered areas. Data are provided in Esri file geodatabase, CSV, and shapefile formats.

Water samples near this abandoned mine were analyzed for specific conductance, pH, temperature, and dissolved oxygen with handheld field meters, and metals were analyzed using inductively coupled plasma-mass spectrometry.

Measured values of water properties, major- and trace-element concentrations in five sample in and near this abandoned mine.

Stream water, groundwater, and ferricrete samples were collected and analyzed to constrain the location of a possible concealed mineral occurrence. Data are provided in CSV and shapefile formats.

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.

Water properties and water chemistry in an area containing abandoned mines where mine drainate is a concern.

Geochemical analyses of solid mill tailings and other ore processing materials from worldwide localities, and leachates from those samples. Data are provided in CSV format.
