Analyses to establish the background and baseline geochemistry for bedrock and soil in the region, and to determine terrestrial mercury sources and sinks in the park
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.
