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.
The presentation in Philadelphia focused on remedial design, construction, and operation of the in situ thermal treatment and enhanced bioremediation remedies. The webinar would provide an update on site progress since the end of 2017 and focus on the technical, contractual, and financial challenges associated with transitioning the project from EPA to the New Mexico Environmental Department after 10 years of RA-O. It will also cover the process of transitioning from ERD to monitored natural attenuation and long-term vapor intrusion mitigation and lessons learned. Finally, the webinar will present the GIS-based dashboard that we're using to integrate operation, VOC, geochemical, and microbial data to support continued system optimization (particularly ahead of the transition of RA-O to the state).
