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.

Sequence stratigraphy has arguably revolutionized stratigraphic analysis in the oil and gas industry since the 1970s, but to date, few environmental companies have utilized this power tool. Although many companies have intended on using sequence stratigraphic correlation techniques to define the subsurface heterogeneity, they have mistakenly used lithostratigraphy, significantly limiting their ability to construct accurate CSMs and develop effective remedial strategies. In this seminar, we will leverage case studies to make participants aware of the pitfalls of lithostratigraphy and highlight the role of sequence stratigraphy in generating robust and realistic hydrogeological models.

Presenters:

Junaid Sadeque, AECOM (Junaid.Sadeque@aecom.com)
Dr. Junaid Sadeque is a recognized Subject Matter Expert in sequence stratigraphy and sedimentology. As a Senior Geologist at AECOM, he plays a pivotal role in applying sequence stratigraphic concepts for predicting contamination flow paths and developing CSMs. Over the past 10 years, he has taught numerous professional courses in applied sequence stratigraphy both locally and internationally. His strong background of previously working for the oil sector helps him bring in fresh and cutting-edge concepts of geology to the environmental world. He has a Master's in Petroleum Geology from the University of Bergen, Norway, and a PhD. From UT Dallas, Texas.

Ryan Samuels, AECOM (Ryan.Samuels@aecom.com)
Ryan Samuels holds a MS degree, Sequence Stratigraphy from Texas A&M University- College Station, and a BA degree, Geology from Franklin and Marshall College. His education and career have focused on extrapolating sedimentological and stratigraphic information from cores and well-logs for sequence stratigraphic analysis. Prior to joining AECOM he was in the petroleum industry, conducting sequence stratigraphic analysis in the Denver Basin, Powder River Basin, and Gulf of Mexico. But now, as a lead stratigrapher at AECOM, he is successfully applying his technical skills to develop comprehensive, integrated Conceptual Site Models and guide the design of cost-effective remedial strategies.

Moderator:

Jean Balent, U.S. EPA Technology Innovation and Field Services Division (balent.jean@epa.gov or 202-566-0832)
Ms Balent is on the staff of the EPA's Technology Innovation and Field Services Division where she has worked to collect and disseminate hazardous waste remediation and characterization information since 2003. Ms Balent manages the Clean Up Information Network website and actively supports online communication and collaboration resources available to EPA. She formerly worked with the US Army Corps of Engineers Environmental Engineering Division in the Buffalo District. Ms Balent was also a member of the SUNY-Buffalo Groundwater Research Group where she constructed and tested large scale models of groundwater flow. Ms Balent has also conducted research relating to the Great Lakes, environmental remediation, and brownfields re-development. She holds a Bachelor's degree in environmental engineering from SUNY-Buffalo and a Master's degree in Information Technology from AIU.
