Getting Started with Thermal Remediation
January 29, 2025 | 10:00 AM Pacific / 1:00 PM Eastern
In this first webinar of our series titled “The Nuts and Bolts of Thermal Remediation,” we will introduce the fundamentals of thermal remediation, covering the key contaminant removal and destruction mechanisms as well as the primary thermal technologies available. We will explore the benefits and limitations of each technology in relation to site geology and hydrogeology, addressing conditions like above and below the water table, high permeability / high groundwater flow settings, fractured bedrock, and complex sites with mixed permeability layers.
We will also cover the three basic thermal treatment approaches: low (35 to 90°C), moderate (100°C), and high temperature (greater than 100°C), discussing their sweet spots, what contaminants can be treated with each, and why you would choose one over the others. The session will wrap up with a case study demonstrating how multiple thermal technologies were successfully combined to effectively treat a CVOC DNAPL site with both low and high groundwater flow conditions.

Whether you’re facing a complex MGP site or a similar contaminated site, this webinar will provide valuable insights into the practical application of thermal remediation and the importance of data-driven decision-making. Walk away with a deeper understanding of how to optimize TCH strategies for challenging sites and achieve successful project outcomes.
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.
The Fate of PFAS During Thermal Remediation
Is it possible to remediate PFAS contaminants? Our research and experience indicate that it is indeed possible using high-temperature thermal remediation, although there are important factors to consider to ensure complete removal and treatment of not only target PFAS but also non-target PFAS such as precursors. In this webinar, we dive into the science of using thermal remediation to treat soil contaminated with PFAS and explore the use of our proven high-temperature thermal remediation technology, where soil temperatures ranging from 350 to 500 degrees Celsius are maintained to achieve stringent cleanup levels. Through our research, which we will share during the webinar, we were able to close the fluorine mass balance and determine the fate of the PFAS compounds during thermal treatment. This allowed us to assess the effectiveness of high-temperature thermal remediation on the removal of PFAS from soil and to design appropriate off-gas treatment systems to ensure that the potential to emit both target and non-target PFAS, including fluorinated hydrocarbons like CF4 and other significant greenhouse gasses, are appropriately managed.

How are SVOCs Treated Using Thermal Remediation?
The treatment of sites with recalcitrant semi-volatile organic compounds (SVOCs) such as PFAS, PCBs, dioxins, and PAHs can feel daunting. A lot of times it seems like the only option is to dig them up and dispose of them in a landfill. But this presents real long-term liability risks for clients. Fortunately, there’s an effective on-site solution for treating soil contaminated with SVOCs – high temperature thermal Remediation.
In this flash webinar, TerraTherm thermal experts Erin Hauber, Senior Technologist, and John LaChance, Vice President of Development, will provide a brief overview of thermal remediation and how it removes and/or destroys SVOCs in soil.
