Given the COVID-19 national health emergency and its affects on corporate/government travel policies as well as local/state health requirements, it has become necessary to hold the conference as a remote webinar based event. With the DCHWS Philadelphia Conference being canceled earlier this year, our fall conference will be co-sponsored by the SAME Philadelphia Post, the SAME Denver Metro Post, and the U.S. Environmental Protection Agency.

Registration for this session closed on October 22. For more information on this session, please visit the sponsor's event website.

A photograph of Lauren SoosLauren Soos, TRS Group. Inc. (
Lauren has over 17 years of experience in the environmental consulting and remediation industries, focusing on soil and groundwater remediation. Over 10 years ago, as an environmental engineering consultant, Lauren was exposed to the fast-paced implementation and certainty of in situ thermal remediation (ISTR) and became obsessed with the technology. Shortly after, Lauren joined TRS Group (TRS) and has been directly involved with over a dozen of ISTR projects throughout the United States. As an engineer and manager in the TRS operations and technical sales teams, she oversees ISTR design, implementation, and operations. Lauren lives in New Hampshire with her husband, Seth, and daughters, Emma and Isla. Their favorite family activity is skiing, which they think is pretty awesomesauce, an adjective their youngest daughter uses to describe these recent adventures.
