Geochemistry Of Metals And Nutrients In Fine-Sediment Pore Water In Blacktail And Silver Bow Creeks, Butte, Montana, Robert Radar
Geochemistry Of Metals And Nutrients In Fine-Sediment Pore Water In Blacktail And Silver Bow Creeks, Butte, Montana, Robert Radar
Graduate Theses & Non-Theses
Historical mining in Butte, Montana has impacted surface and groundwater in the area. Although most of the known sources of contaminants of concern have been removed or remediated, metal loading continues to occur in lower Blacktail Creek and upper Silver Bow Creek. Possible sources of metals include upwelling groundwater and interaction between the stream and metal-rich sediment in the stream bed. To assess the importance of fine sediment as a source (or sink) for metals, this investigation used sediment pore water diffusion samplers (“peepers”). Peepers are ideal for capturing cm-scale vertical gradients in pore water chemistry across the sediment-water interface. …

Developing Trees Tolerant To Degraded Mine Soils, Francis Inkoom
Graduate Theses & Non-Theses
The project discussed in this thesis is part of a larger project developing trees that can tolerate and withstand heavy metals and acidic soils from historic mining operations in Butte Montana as a solution to re-establishing long-term tree growth on those sites. The project involved growing tree seedlings native to Butte, Montana and planting them on degraded mine soils, tailings, and processing wastes (mine waste) located within the Butte Priority Soil Operable Unit (BPSOU). The seedlings were grown for 34 weeks in a greenhouse located on Montana Tech’s campus before being transplanted to a contaminated site (the Clark Mill site) …
