Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
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.
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.
Details of materials and geologic environments in an area where a long history of mining has enriched stream sediments in silver, lead, zinc, arsenic, antimony and mercury, copper, cadmium, manganese, and iron.
Chemical composition of sediments and soils are of interest because of the potential for human and wildlife health impacts from high metal contents due to over 100 years of mining activity.
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.
