Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
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.
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.
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.
Data from field sampling of mine tailings, wasterock, sediment, water, and biota at the mine in 2010. Results permit a preliminary assessment of the mining sources of Hg and associated chemicals that could produce elevated levels of monomethylmercury.
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.
Geochemical analysis of water samples to provide a pre-reclamation assessment of seasonal variations of acid and metal concentrations in Knight's Branch help evaluate the reclamation project.
An environmental impact study is done for the abandoned Ely copper mine. The extent of contamination is studyed along with the type and chemical composition of the mine waste piles.
