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

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.

What You Need to Know About Thermal Remediation for MGP Sites
When a manufactured gas plant (MGP) site is identified for treatment, the typical remediation approach can be expensive and involve hazards for crews and the community. Any time you excavate contaminated soil and transport it for treatment or disposal, you are introducing potential safety and liability issues. Luckily, in situ thermal remediation (ISTR) is often a safe and cost-competitive alternative.
Join this webinar where our Vice President of Development, John LaChance discusses:
- Primary ISTR technologies, their applicability, and primary removal mechanisms at MGP sites
- Key design considerations for varying conditions and remediation goals
- A case study of an MGP site remediated with ISTR, including:
- Analysis and discussion on the potential role of in situ smoldering in the removal of creosote/coal tar
- Insights into projects with unique goals, such as
- Volatilization of low boiling point compounds
- In situ immobilization of high boiling point compounds, including heavier range TPH and PAHs.
ERH and TCH – How to Choose Your Thermal Remediation Technology (and Why)
It’s one of the most commonly asked questions when considering thermal remediation, and in this webinar one of the industry’s leading experts will answer it. Join TerraTherm, a Cascade Company’s Vice President John LaChance as he introduces the basic operational theory and concepts for both technologies. He’ll discuss their application to a set of typical site conditions (e.g., low and high permeability zones in unconsolidated and bedrock formations) and contaminants (e.g., CVOCs), and highlight typical design approaches, assumptions, and the pros and cons of each.
John will share real-life examples of full-scale projects involving electric resistance heating (ERH) and thermal conductive heating (TCH), including detailed breakdowns and comparisons of costs. He’ll also touch on ETDSPTM, a form of ERH that employs active injection and extraction of water. If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.
Which is Better? Electric Resistance Heating (ERH) or Thermal Conduction Heating (TCH)?
Electric resistance heating (ERH) and thermal conduction heating (TCH) have many similarities, and it can be hard to figure out which one is best suited for a specific project site. It’s critical to know the pros, cons, and differences of each because making the wrong call on technology selection can have expensive repercussions.
In this 30-min webinar VP of Development, John LaChance and Senior Technologist, Erin Hauber will give you a quick overview of the basic operational theory and concepts for both technologies and discuss their application to a set of typical site conditions.

ISTR Challenges Part 2: Electrical Resistance Heating and Steam Enhanced Extraction
Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) are widely used thermal technologies capable of effectively remediating a variety of chemicals in various varying subsurface settings, yet sometimes operations do not perform as planned. An experienced thermal remediation contractor can help you anticipate and address site-specific challenges during full-scale thermal projects.
Presented by Vice President of Development, John LaChance and Vice President of Technology, Steffen Griepke, ISTR Challenges Part 2 covers some of the common issues that can arise at ERH and SEE sites, and discuss how they should be addressed. You’ll hear about scenarios involving
- significantly different soil electrical resistivities than planned
- slower than expected heat-up
- stray voltages and currents
- poor steam quality
- higher than expected mass removal rates
- lack of hydraulic control
- non-uniform steam delivery and heating
