Current Projects:
1) Metal sources and behavior in potential drinking water aquifers impacted by CO2 leakage
2) Porosity and permeability changes in geochemically reactive environments
3) Coupled reactive transport and land surface processes at watershed scale
4) Quantification and evolution of connected and accessible surface area

Research Interests:
complex coupling of geochemical and hydrological processes in natural systems at scales from basins to pore networks.  My current research focuses on rock weathering, underground CO2 storage and metal release and transport.  I use a variety of advanced characterization tools and reactive transport models to understand these processes in both experimental and field systems and hopefully, ultimately, predict the rates of geochemical processes.

Activities:
• Co-convener of multiple special topics sessions in geochemistry and hydrology at American Geophysical Union and Geological Society of America National Meetings
• Active member of American Geophysical Union, Geological Society of America, Geochemical Society
• Peer reviewer for: G-cubed, Applied Geochemistry, Geochimica et Cosmochimica Acta, Chemical Geology, Earth and Planetary Science Letters, Aquatic  Geochemistry, IODP 301 Expedition Proceedings

Jonathan Sharp
Assistant Professor
Department of Civil and Environmental Engineering
Colorado School of Mines
jsharp@mines.edu

Research Interests: Environmental concerns are a predominant theme for the 21st century as society realizes the importance of sustainability and resource conservation for our long-term health and prosperity. As an environmental engineer trained in combining molecular and microbiological tools with geochemistry, my research focuses on the applications and implications of biological processes that relate to water quality and reuse. I have applied my cross-disciplinary perspective towards investigating the bacterial degradation of emerging drinking water and biosolids-associated organics and towards understanding bacterially-mediated redox transformations of both metals and radionuclides. I am interested in bioremediation problems in natural waters and sediments and in drinking and wastewater.

Activities:
• Undergraduate student and community outreach addressing water quality implications associated with abandoned mine runoff through the Clear Creek Watershed Foundation
• Liaison and volunteer for Front Range Earth Force. Activities include development of an instructor module, Google Earth curriculum insert and middle school environmental outreach
• Teaching 3 courses: "Fundamentals of Environmental Engineering", "Geomicrobial Systems", and "Environmental Engineering Field Session"
• Co-chair, Session on molecular-scale chemical and biogeochemical processes affecting the mobility of metal and radionuclide contaminants in the subsurface: structures of nanostructured minerals and minerals with incorporation of dopants at the 18th International  Goldschmidt Meeting. Vancouver, Canada.
• Ad hoc peer-reviewer for: Environmental Science and Technology, Bioremediation, FEMS Microbial Reviews, Water Research

John Stednick
Professor, Watershed Science
Department of Forest and Rangeland Stewardship
Colorado State University
jds@cnr.colostate.edu

Dr. Stednick serves as Professor and Program Leader, Watershed Science Program, Department of Forest, Rangeland, and Watershed Stewardship. Educational background is B.Sc. in Forest Sciences and Ph.D. in Forest Resources from University of Washington. Current interests include land use and water quality, forest hydrology, water quality hydrology, biogeochemistry, water chemistry, soil chemistry, hydrometry, watershed management, risk assessment, watershed analysis, environmental impact assessment, and technology transfer. The following projects demonstrate the approach of using collaborative efforts: effects of irrigation with urban exchange waters on soil and water quality, nutrient criteria selection for undisturbed watersheds, effects of managed groundwater recharge on water quality, forest management effects on water yield and water quality, nitrogen sources in surface waters in the Glacier Lakes Experimental ecosystem, effects of prescribed fire on water chemistry, effects of surface and groundwater interactions on sodium adsorption ratios in coal bed methane extraction waters, and effects of beetle killed forests on water quantity and quality. Recent international efforts include Vietnam, Laos, Canada, Namibia, and Belize.

Activities:
• Colorado Bark Beetle Cooperative. Presentations made to stakeholder audiences on the effects of beetle-killed forested watersheds on water quality and water resources in general.
• Greenlands Reserve. Presentations and field trips to watershed stakeholder on watershed health improvement projects.
• USDA Forest Service. Evaluation of ongoing watershed health improvement projects and their relation to water resources.
