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 highlight a talk from the Third Western Symposium Design and Construction Issues at Hazardous Waste Sites (DCHWS) held November 5-7, 2018. The presentation will discuss a project now in the Feasibility Study (FS) stage, which has developed unit costs for key technologies that will be used in the Big River FS. The site team will have draft alternatives (incorporating sediment traps, bank stabilization, and conventional technologies) developed by the end of August 2019 and be ready for discussion. A side-by-side discussion of remedial strategy for Big River watershed and remedial strategy for Spring River watershed will be included. Big River focuses on larger river channel further away from historic sources. Spring River focuses on smaller, more dynamic tributary channels with historic sources distributed around the watershed in close proximity to impacted streams. The comparison will illustrate how the larger strategy can be adapted to site-specific conditions. Also, the site team plans to have multiple pilot tests of innovative technologies. One of the pilots is finished, with two in progress now. The presentation will highlight how the team is applying pilot testing to refine the application of these innovative technologies prior to full scale remediation.
