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.
This broadcast is pre-recorded, however, you will still be able to ask John questions and we will answer them following the event.

Williams Air Force Base Steam Enhanced Extraction Project – The Largest Steam Project in the World
Join a webinar that will take you on a journey through the transformative efforts at the former Williams Air Force Base in Mesa, Arizona, a former Liquid Fuels Storage Facility (ST012) Superfund Site, where historic releases of JP-4 jet fuel culminated in an estimated spill of 1 to 11.1 million gallons of contaminants.
The site underwent a comprehensive three-stage remediation approach, commencing with the world’s largest Steam Enhanced Extraction (SEE) project, followed by Enhanced Bioremediation (EBR), and concluding with Monitored Natural Attenuation (MNA). This session will shine a spotlight on the monumental first stage – SEE.
The project’s magnitude brought forth a myriad of challenges, from selecting equipment capable of withstanding extreme conditions and high contaminant loads to evaluating pumping systems able to extract hot steam, contaminants and water from up to 240 ft bgs. Delve into how the team navigated these obstacles and innovatively utilized the recovered LNAPL as a sustainable auxiliary fuel source for the vapor treatment system. The presentation will unveil the outcomes of the SEE phase, emphasizing the ingenious strategies implemented to overcome the challenges during the design and operation at ST012.

Fast, Reliable Remediation: Why Thermal Should Be On Your Short List for Redevelopment Projects
Redevelopment projects can revitalize business districts and create new opportunities for local communities, but they are not without their challenges. Before being fully utilized, many sites must first address long-ignored soil and groundwater contamination.
This is no easy task under normal circumstances, but redevelopment projects often have sensitive schedules that can cost the site owner and developer millions of dollars if they aren’t met—or result in the project being abandoned altogether. Remediation technologies and strategies that can achieve site goals quickly and reliably are critical to project success.
In this webinar, thermal expert John LaChance will discuss how thermal technologies can quickly and efficiently remediate contaminated sites for reuse. He’ll dive into some of the challenges specific to former industrial sites, as well as strategies for overcoming them. John will also share real-life examples of using in situ thermal remediation (ISTR) to clean up impacted properties for sale and reuse.
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. They will also explain why thermal conductive heating (TCH) is the primary ISTR technology for the remediation of high boiling point chemicals. They will also discuss how TCH is used for In Pile Thermal Desorption (IPTD) of SVOCs, important design do’s and don’ts for a successful remedy, common ISTR myths, and typical costs.
How are VOCs Treated Using Thermal Remediation?
Add heat to remediate! Sounds simple enough, but do you ever wonder how raising the temperature can be so effective at removing volatile organic compounds (VOCs) from soil and groundwater, even from difficult-to-remediate low-permeability silts and clays?
TerraTherm technology experts Nikole Huard and John LaChance introduce the primary thermal technologies and mechanisms responsible for this amazing feat. Key site information useful in evaluating whether In Situ Thermal Remediation (ISTR) is the best option for your site will also be covered. They review:
- Important design do’s and don’ts for a successful remedy,
- Common ISTR myths, and
- Typical costs for ISTR at a VOC site.
