Dr. James J. Stone is a professor of Civil and Environmental Engineering at South Dakota School of Mines and Technology (SD Mines) in Rapid City, South Dakota. His research focuses on life cycle assessment (LCA) modeling, heavy metal (U, As, Hg) fate and transport, and wastewater and stormwater treatment systems. He has developed LCA models for stormwater best management practices, swine and beef feedlot productions, feed production, and antibiotic manufacturing. His recent LCA efforts have been related to utilization of LCA as an assessment and management tool for decision making processes.

Assessment
LCAs quantify the full range of environmental impacts of products and services to assess their ecobalance. This information is used to improve efficiency of processes and make informed decisions.
Accelerated biodegradation of non-recyclable household waste can be used to produce methane and topsoil within a portable, containerized unit that captures methane. Methane can then be used as a fuel for either heating or energy production.

Contamination
In-situ mining of uranium poses contamination concerns. Research is on-going on subsurface uranium redox geochemical mobilization and post-mining reclamation modeling.
