Establishing A Vegetative Cap For Sustainable Stabilization Of Copper Contaminated Soils In Torch Lake, Michigan, Virinder Pal Singh Sidhu
Establishing A Vegetative Cap For Sustainable Stabilization Of Copper Contaminated Soils In Torch Lake, Michigan, Virinder Pal Singh Sidhu
Theses, Dissertations and Culminating Projects
Extensive mining activities during the late 19th and early 20th centuries in the Upper Peninsula, Michigan have resulted in a number of contaminated sites with mine tailings. Several million metric tons of mine tailings were generated during the peak of copper (Cu) mining activities in this region. These tailings are called “stamp sands” because they were generated by crushing native Cu containing rocks, by a process known as stamping. The stamp sands were discharged into Lake Superior, other interior lakes and their shorelines, converting these areas into vast, fallow lands. The Cu contaminated stamp sands are being eroded back into …
Green Remediation Of Acid Mine Drainage (Amd)-Impacted Soil And Water, Abhishek Roychowdhury
Green Remediation Of Acid Mine Drainage (Amd)-Impacted Soil And Water, Abhishek Roychowdhury
Theses, Dissertations and Culminating Projects
Although mining industries such as coal and minerals generate revenue, they are responsible for a number of negative environmental consequences, and the production of acid mine drainage (AMD) and acid sulfate soil are the most concerning among them. Current AMD management practices are expensive, ineffective, or unsustainable. This study evaluated the potential of a cost-effective and environment-friendly “green” technology in treating AMD-impacted water and soil that utilizes the metal-binding and acid-neutralizing capacity of an industrial by-product, namely drinking-water treatment residuals (WTRs) and the extensive root system of a metal hyper-accumulating, fastgrowing, non-invasive, high biomass perennial grass, vetiver (Chrysopopgon zizanioides …
Socioeconomic And Environmental Assessment Of Woody Biofuels In Southern United States, Bernabas T. Wolde
Socioeconomic And Environmental Assessment Of Woody Biofuels In Southern United States, Bernabas T. Wolde
Theses, Dissertations and Culminating Projects
Although the emergence of woody bioenergy offers several energy, economic, social, and environmental benefits, forestland owners’ willingness to participate in a biomass supply market, how it affects land use choices, and forestland owners’ sustainability concerns are not well understood. In addition to these gaps, how much residual biomass forestland owners are willing to retain on site for soil fertility and other environmental benefit purposes and forestland owners’ tendency to enroll in public incentive programs are not fully documented. Because private forestland owners manage two thirds of the 214 million acres of forest cover in the southern United States, understanding their …
