Elliott Andelman, Professional Geologist, Directional Technologies, Inc.

IPEConnect PRESENTATION DATE: November 7, 2024

Horizontal remedial applications including biosparging, soil vapor extraction, and injections remain a proven technique to minimize contaminants located beneath surface infrastructure or heavy traffic areas. This presentation will provide an overview of horizontal remediation well design, installation processes, and remedial applications. Two case studies will be presented for sites where horizontal remediation wells were installed and operated to remediate petroleum plumes at (1) a bulk fuels facility and (2) an underground storage tank (UST) facility.

Mr. Andelman is an Environmental Scientist and Licensed Professional Geologist who works for Directional Technologies, Inc. (DTI), a company that specializes in the design, drilling, and installation of horizontal remediation wells. Elliott received his bachelor’s degree in geology from James Madison University, located in central Virginia. He then received a master’s degree in geological engineering from the University of Wisconsin in Madison. After spending five years working in environmental consulting, where he worked on multidisciplinary remedial projects, both assisting others and managing his own, he joined the Directional Technologies’ team. He now works with environmental consultants to assess how horizontal remediation wells may benefit their more challenging remediation projects.

By attending this presentation, environmental consultants from entry-level to experienced will learn about how horizontal remediation wells can help provide access to obstructed contamination, reduce the remedial timeline, and save money throughout the duration of the project. Horizontal wells can perform any remedial application that vertical wells can, whether it be biosparging, soil vapor extraction (SVE), injections, permeable reactive barriers, and more. Compared to vertical remediation wells, a single horizontal well can have hundreds of feet of screen precisely installed within the contaminated zone. By use of directional drilling techniques, horizontal wells can be placed beneath active facilities, fuel storage tanks, roadways, railroads, and any other surface or subsurface obstruction. As a result, the horizontal screen has significantly more contact with the contaminant plume, providing advanced remediation that reduces the remedial timeline and keeps clients happy.
