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 select seminar topics offered since 2012, we are making complete video recordings available through our archives. This feed contains all video seminars archived in the last 12 months. For a complete list of seminars archived since 2000, please visit http://www.clu-in.org/live/archive/. Our Rehabilitation Act Notice for reasonable accommodation is available at http://www.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.

Ten Years of Optimization of the Environmental Restoration program at a DoD Facility in North Carolina (Sep 15, 2021)
The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals. This session will discuss the investigation and remediation of impacted media which has been ongoing at a DoD facility in North Carolina for more than 25 years. Since 2010, the environmental restoration program at the facility has been proactively optimized through the implementation of innovative technologies, focused treatment, and well-defined exit strategies to minimize remediation timeframes, reduce life-cycle costs, and to move away from long-standing pump and treat remedies-in-place and passive long-term monitoring programs. Technologies have included in situ aerobic bioremediation, in situ chemical oxidation, enhanced reductive dechlorination, air sparging, biobarriers, recirculation, bioaugmentation, and subgrade biogeochemical reactors for the treatment of polycyclic aromatic hydrocarbons and chlorinated volatile organic compounds in a variety of hydrogeologic settings around the facility. This presentation will discuss the technologies and various application approaches, lessons learned, mass removal and resulting reduction in time to site closure, optimization, and overall cost savings for the restoration program.
