Site Cleanup with Low Temperature Thermal and Heat-Enhanced Remedies

Part 1: Understanding the Science and Strategy Behind Low Temperature Thermal Remediation – September 24, 2025

Join us for the first session in this two-part webinar series, where remediation experts John LaChance and Erin Hauber will introduce the fundamentals of low temperature thermal and heat-enhanced remediation. Learn how gently heating the subsurface—typically between 35°C and 90°C can amplify chemical, biological, and physical processes to accelerate cleanup, improve remedy reliability, and reduce life-cycle costs.

We’ll explore:

• How low temperature thermal remediation supports natural attenuation and injection-based remedies
• The contaminants of concern (COCs) best suited for heat-enhanced treatment
• Key differences between low temperature and full thermal (100°C) applications
• When and why to consider low temperature thermal as part of your site strategy

Part 2: Real-World Applications and Lessons Learned – October 22, 2025

In the second session, we’ll build on the foundational concepts with two in-depth case studies that demonstrate how low temperature thermal remediation has been successfully applied in the field.

You’ll see how:

• A site with a persistent CVOC DNAPL source beneath an active facility was treated using 35°C heating in combination with EVO/ZVI injections
• Another site achieved effective cleanup of a halogenated DNAPL (EDB) using 70–80°C heating to enhance hydrolysis, without the need for vapor covers or extraction systems

We’ll also revisit the mechanisms, COCs, and technologies discussed in Part 1 to reinforce key takeaways and provide practical insights for your projects.
