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.

Thermal 101: What Is Thermal Remediation And How Does It Work?
In the last 20 years, thermal remediation has gained a reputation as one of the most effective approaches for addressing sites with hard-to-treat constituents, everything from VOCs, SVOCs and PAHs to MGP coal tar and dioxins. But to achieve site goals, the project has to be well engineered, with a clear understanding of…
- The geological setting
- Which contaminants are being addressed and where they are in the subsurface
- The estimated mass of constituents to be removed
- Which heating technologies are best suited for the site
- The timeframe available for the project
- What the remedial objectives are, and more.
In this webinar, thermal experts Nikole Stone and Steffen Griepke will cover the basics of thermal remediation. They’ll explain how the three primary thermal technologies work, what constituents and lithologies they’re best suited to treat, typical project timeframes, and a few real-life examples. There will also be time for a Q&A, so be sure to bring all the questions about thermal remediation you’ve never had a chance to ask.
If you’re interested in gaining a basic understanding of thermal technology, this is a webinar you won’t want to miss.
ERH vs. TCH: How to Choose Your Thermal Remediation Technology (and Why)?
“How do I choose between ERH and TCH?”
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.
Low Temperature Thermal: The Sustainable Approach
“Thermal” and “sustainable” in the same sentence?!
Yes! Although most often associated with a high demand of resources and infrastructure, thermal remediation can be accomplished sustainably.
In this webinar, John LaChance and Hillary Easter will explain how low-temperature thermal technology can address your challenges in an environmentally and economically friendly manner. They will describe how the technology works, and the remediation mechanisms targeted by low-temperature thermal. He’ll also cover which contaminants of concern (COCs) are most suited for this approach, costs, and timeframe.

Thermal Remediation of High Mass Hydrocarbon Sites: When NAPL Capture Governs the Mass Recovery
On sites with contaminant masses counted in the hundred-thousand to million pound range, it’s imperative you choose the right technology for your remedy.
Thermal Technologies are widely used to target high mass contaminated sites where non-aqueous phase liquids (NAPLs) are known to be present. While the geology and hydrogeology of a site typically is a driving factor for technology selection, the mass distribution, chemical composition and thermal behavior for the site contaminants are often the key drivers in determining in which phase the mass is mobilized, and thus the extraction strategy. For VOCs, mobilization in the vapor phase typically fully governs the mass removal. However, for more complex mixtures of high boiling point hydrocarbons, that may not be the case.
In this webinar, Technology Director Steffen Griepke explains what to consider when selecting and designing your thermal remedy for optimized mass removal. He shares best practices and examples drawn from the two decades he worked in thermal remediation.
Real-Time Solutions to Unexpected Challenges Encountered During Thermal Remedy Implementation
An in situ thermal remediation (ISTR) design may look good on paper, but how will it perform in the field?
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. Due to the aggressive nature of thermal remediation in parallel with pro-active monitoring, operational challenges must be addressed immediately, typically within days rather than weeks. Lessons learned from more than 100 full-scale TCH, ERH and SEE projects will be discussed, focusing on common operational challenges that arise during full-scale thermal projects.
Thermal Remedy of Fractured Crystalline Rock
Investigating and remediating fractured rock can be a lot more complex than treating a porous media like sand or clay. This webinar will present information and data from projects where thermal remediation was successfully used to clean up sedimentary, metamorphic, and igneous bedrock. The removal mechanisms as well as challenges for using thermal remediation technologies in fractured rock will also be reviewed, along with technology applicability and costs.
Thermal Rediation for Treatment of PFAS Source Areas
Per- and polyfluorinated substances (PFAS) are known as forever chemicals because they are persistent in the environment and difficult to remove. Tackling these contaminants is feasible with the right technology. Thermal conductive heating (TCH) is an effective remediation solution for PFAS and other recalcitrant compounds. Recent laboratory studies conducted by TerraTherm partner Krüger have shown better than 99.99% removal of PFAS contaminants when simulating the TCH efficiency.
You know there’s more to project success than technology alone. Experience matters. TerraTherm’s Technology Director with guest speaker Søren Eriksen, Chemical Engineer from Krüger. They addresses the literature background as it relates to thermal removal of PFAS, describes the conducted lab testing and results. They also touch on the fate of the thermally treated PFAS compounds in the process, and presents how a field application will be implemented.
