Sampling procedures, analytical methodologies, and results to assess the potential for mine waste and drainage to have an adverse impact on aquatic ecosystems, on drinking- water supplies, and to human health
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.
Data from field sampling of tailings, waste rock, sediment, and water at the mines, along with water, sediment, and biota in a pond and tributaries that drain from the mine area, to help assess the chemical hazards due to historic mining.

Geochemical data for all solid sample media, along with mineralogical data, and results of weathering experiments on Valzinco tailings and field experiments on sediment accumulation in Knights Branch.
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.
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.
This large producer of mercury operated from 1933 to 1971. As part of remediation work, this survey used electromagnetic methods to study subsurface resistivity.
