Thermal Remediation of MGP Sites, From Strategy to Real-World Performance

Former manufactured gas plant (MGP) sites present some of the most complex remediation challenges, driven by coal tar DNAPL, high contaminant mass, and difficult subsurface conditions that limit the effectiveness of conventional approaches.

This two-part webinar series explores how thermal remediation is applied to address these challenges, from initial evaluation and system design through real-world implementation and performance.

In the first session, attendees will learn how thermal remediation targets coal tar source zones, performs in low-permeability soils, and supports efficient cleanup aligned with regulatory and redevelopment goals. The webinar focuses on key design and implementation considerations, including contaminant profiles, treatment depths, and strategies for managing large contaminant mass, along with how thermal technologies can be integrated with complementary remedies to strengthen overall performance.

The second session builds on these concepts through case studies that demonstrate how thermal remediation systems perform under actual site conditions. Drawing on multiple projects, this webinar walks through the full implementation lifecycle, highlighting how teams have navigated complex subsurface conditions, adapted to field challenges, and achieved successful outcomes.

Together, these sessions provide a practical, field-driven perspective on applying thermal remediation at MGP sites and offer insights that support more informed, defensible remediation strategies.

In this two-part series, you will learn how to:

• Evaluate when thermal remediation is the right fit for MGP sites
• Apply key design and implementation strategies for coal tar source zones
• Manage high contaminant mass and complex subsurface conditions
• Connect site data to technology selection and system design
• Navigate field challenges and adapt during implementation
• Benchmark real-world performance to support defensible decisions
• Soil Sampling Fundamentals: Methods, Tools, and When to Use Them

Applying Thermal Remediation at MGP Sites, Design and Implementation Considerations

Presenter: Steffen Griepke

Former manufactured gas plant (MGP) sites are some of the most challenging to remediate due to coal tar DNAPL, high contaminant mass, and complex subsurface conditions that limit the effectiveness of conventional remedies. 

In this webinar, you’ll learn how In Situ Thermal Remediation (ISTR) is applied to address these challenges and improve project outcomes. This session focuses on how ISTR targets coal tar source zones, performs in low-permeability soils where other approaches are often limited, and supports efficient cleanup timelines aligned with regulatory and redevelopment goals.  

MGP Site Remediation in Action, Case Studies and Lessons Learned

July 22, 2026 | 10 AM PST/ 1 PM EST

Presenters: Erin Hauber and John LaChance

The true test of any remediation technology is how it performs under real site conditions. In this case study-based webinar, you’ll explore how thermal remediation has been applied to address complex coal tar impacts at former manufactured gas plant (MGP) sites.

Through multiple project examples, our experts will walk through the full lifecycle of ISTR applications, including site conditions, technology selection, system design, operational performance, and final outcomes. The discussion highlights how teams navigated challenging subsurface conditions, managed large contaminant mass, and adapted to unexpected field realities.
