Innovations in Remediation at the Center for Bio-mediated and Bio-inspired Geotechnics

Sponsored by: US EPA and Center for Bio-mediated and Bio-inspired Geotechnics (CBBG)

Go to Archive

Environmental remediation and restoration is one of four thrust areas of the Center for Bio-mediated and Bio-inspired Geotechnics (CBBG), a National Science Foundation (NSF)-sponsored Gen-3 Engineering Research Center. Consistent with its mission to develop transformative solutions for sustainable and resilient infrastructure, CBBG investigators are working on a variety of environmental remediation technologies, including combined biotic and abiotic remediation of chlorinated solvents, remediation of acid rock drainage, remediation of metals and metalloids, and fugitive dust mitigation. CBBG also has a robust Industry Partner program that fosters direct participation of industry in CBBG research at reduced overhead rates and an Education, Outreach, and Diversity and Inclusion program designed to meet NSF's goals for workforce development in this emerging field.


In this presentation, an overview of CBBG environmental research and Industry Partner programs will be followed by an in-depth presentation on bioremediation of chlorinated solvents. The chlorinated solvents presentation will recap over a decade of progress on this topic at Arizona State University, the lead academic partner in CBBG, with a special focus on microbial competition for hydrogen. The webinar will close with a case history (treatability study) on remediation of trichloroethene and perchlorate via application of innovative remediation techniques developed by CBBG researchers for a challenging Superfund site in the Phoenix metropolitan area. Challenges addressed in this case history include aerobic groundwater and very high sulfate concentrations.

Edward Kavazanjian, Jr.Edward Kavazanjian, Jr., Director, Center for Bio-mediated and Bio-inspired Geotechnics (Edward.Kavazanjian@asu.edu or 480-727-8566)
Dr. Edward Kavazanjian, Jr. is a Regents Professor and the Ira A. Fulton Professor of Geotechnical Engineering in the School of Sustainable Engineering and the Built Environment at Arizona State University in Tempe, Arizona, USA. He joined the faculty at Arizona State University in August 2004 after 20 years as a practicing geotechnical engineer. He currently serves as Director of the Center for Bio-mediated and Bio-inspired Geotechnics, a US National Science Foundation-funded Engineering Research Center focused upon the emerging field of biogeotechnical engineering. Dr. Kavazanjian has Bachelor and Master of Science degrees in Civil Engineering from M.I.T. and a Ph.D. in Geotechnical Engineering from the University of California at Berkeley. Upon completing his Ph.D. in 1978, he joined the faculty at Stanford University. In 1985, Dr. Kavazanjian left academia and spent the next 20 years working in engineering practice.

Dr. Kavazanjian is widely recognized for his work on design and construction of landfills and waste containment systems and on geotechnical earthquake engineering. In 2013 he was elected to the US National Academy of Engineering for his contributions in these areas. He is co-author of the Environmental Protection Agency guidance document on RCRA Subtitle D (258) Seismic Design Guidance for Municipal Solid Waste Landfill Facilities and the Federal Highway Administration guidance document on LRFD Seismic Analysis and Design of Transportation Geotechnical Features and Structural Foundations. He is recipient of the 2009 Ralph B. Peck Award from the American Society of Civil Engineers (ASCE) for his published case history contributions to landfill engineering, co-recipient of the 2010 Thomas A. Middlebrooks award for his paper in the ASCE Journal of Geotechnical and Geoenvironmental Engineering on Shear Strength of Municipal Solid Waste. In 2011, he received the Terzaghi Award from ASCE for his contributions to soil mechanics and earthworks engineering through his publications in ASCE on landfill engineering and waste containment systems. Dr. Kavazanjian is a registered Professional Engineer in Arizona, California, and Washington.
