Application of ERH and SEE to Address Complex Geology and High Groundwater Flux Zones to Treat a PCE DNAPL Source Zone

Thermal remediation at sites with complex geologies where there are both high and low groundwater flow zones requires innovative engineering and a multi-technology approach to achieve success. The Hamilton/Labree Roads superfund site presented such challenges, including a PCE DNAPL source zone beneath a road and a creek, complex hydrogeologic conditions, and high groundwater flux zones. In this webinar John LaChance, VP of Development at TerraTherm will cover:

• Detailed Site Model: Understand the importance of a detailed conceptual site model (CSM) and site lithology in designing an effective remedy.
• Comprehensive Approach: Learn how multiple technologies were integrated to tackle the site’s unique complexities and achieve the remedial objectives safely and effectively.
• Technological Implementation: Discover how 49 steam injection wells (SIWs) and 82 ERH electrodes were used to effectively heat the site, and how a variety of extraction systems were used to maintain pneumatic and hydraulic control.
• Innovative Solutions: Explore the engineered solutions used to protect the creek, including an insulated channel and continuous temperature monitoring.
• Proven Results: Review the outcomes of the remediation process, including achieving soil concentration goals and removing over 7,800 lbs of contaminants.

Join us for an in-depth session into the lessons learned during the design, construction, and operation phases of this successful thermal remediation project. Gain valuable insights from real-world applications and understand how to address the challenges of complex geologic systems with high groundwater flux zones.
