Since 1998, The Contaminated Site Clean-Up Information (CLU-IN) website has presented Internet Seminars covering a wide variety of technical topics related to hazardous waste characterization, monitoring, and remediation. For each seminar topic, we have selected the highest-quality offering for placement in our archives. Beginning in May 2005, we began offering these archives via podcast, and this feed contains all seminars archived in the last 6 months. For a complete list of seminars archived since 2000 and videos of selected seminars archived since 2012, please visit http://clu-in.org/live/archive/. Our Rehabilitation Act Notice for reasonable accommodation is available at http://clu-in.org/training/accommodation.cfm. CLU-IN was developed by the U.S. Environmental Protection Agency (EPA) but is intended as a forum for all waste remediation stakeholders.

Audio for "Innovations in Remediation at the Center for Bio-mediated and Bio-inspired Geotechnics," Dec 12, 2019
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.
