Mining of stibnite (antimony sulfide), tungsten, gold, silver, and mercury near the town of Stibnite in central Idaho has left a legacy of trace element contamination in the East Fork of the South Fork of the Salmon River (EFSFSR) and its tributaries. Concentrations of arsenic, antimony, and mercury frequently exceed human health criteria and may impact threatened or endangered salmonid species, including Chinook salmon, steelhead, and bull trout in the EFSFSR. The purpose of this study is to quantify contributions of select trace elements and suspended sediment from different stream reaches, assess potential toxicity to human and aquatic life, and explore the use of surrogate parameters such as specific conductance to improve estimates of concentrations and loads of select constituents.

Trace Metal Mobility in the Yellow Pine Mining District, Idaho
The study objective is to conduct an integrated, interdisciplinary study on source areas, biogeochemical transformations, and physical and biological pathways for trace metal transport in a tributary of the Snake River watershed, focusing on the Sugar Creek watershed. The historical Cinnabar mercury mine site is at the headwaters of Cinnabar Creek, a tributary to Sugar Creek. This integrated... - Multimedia
