Heating Up the Fight Against PFAS: Great strides have been made in using Thermal Conduction Heating (TCH) to clean up soil contaminated with Per- and Polyfluoroalkyl Substances (PFAS). This webinar dives deep into the latest research, exploring burning questions for environmental consultants, engineers, and scientists:

• Can TCH effectively destroy PFAS at real-world sites?
• Are regulators on board with this innovative approach?
• What does a full-scale PFAS remediation project using TCH entail?

Join us for an engaging discussion led by John LaChance, Vice President of Development at TerraTherm. Over the past 20 years, John has become a leading expert in thermal remediation technologies, including TCH. He helps clients select the right technology to effectively and efficiently remediate their sites, meet regulations, and ultimately enable property reuse. With over 50 successful in situ thermal remediation projects, John brings a wealth of technical and strategic insight to the thermal remediation field.

In this webinar, John will share:

• Proven results: Explore research findings from bench-scale testing, demonstrating the effectiveness of TCH in destroying PFAS.
• From lab to land: Learn how TCH systems are designed and deployed for real-world soil treatment, including details on vapor and liquid treatment methods.
• Monitoring made easy: Discover how extracted and produced vapors are tracked to ensure compliance with regulations.
• Verifying success: Uncover the latest soil and vapor sampling and analytical techniques to confirm complete PFAS removal, including precursor compounds.
• Market momentum: Is the industry ready to embrace thermal remediation for PFAS? We’ll discuss the current landscape and what’s needed to move forward.

Don’t miss this informative session! We’ll conclude with a dedicated Q&A to answer your burning questions about the future of thermal remediation for PFAS-contaminated soil.

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.

The treatment of sites with recalcitrant contaminants such as PFAS, PCBs, dioxins and PAHs can feel daunting. Fortunately, there’s an effective solution for high-boiling point chemicals – In Situ Thermal Remediation (ISTR).

In this flash webinar, TerraTherm thermal experts Sam Nienstedt, Technologist, and Steffen Griepke, Vice President of Technology, will provide a brief overview of thermal remediation and share how ISTR can remove or destroy subsurface contaminants.  They explain why thermal conductive heating (TCH) is the primary ISTR technology for remediation of high boiling point chemicals. They will also discuss important design do’s and don’ts for a successful remedy, common ISTR myths, and typical costs.

There will be time for questions at the end, so bring your questions about using thermal remediation to treat hard-to-treat contaminants. This flash webinar is scheduled for 30 minutes.

Recalcitrant chemicals like PAH, PCB’s, Dioxins, PFAS, and Mercury, are hard to treat using traditional remediation methods. Sites with these contaminants are nearly unaffected even by thermal treatments at the boiling point of water. However, when we use our Thermal Conductive Heating technology, we can reach target temperatures well above 300 °C and thereby treat these persistent compounds. Join our free webinar, where the experienced team of TerraTherm and KrugerVeolia experts will discuss:

• Where high-temperature remediation is applicable
• Which chemicals can be targeted
• What results can be achieved
• Tailoring of implementation approaches and specific sites examples
• In situ and ex-situ case study examples.

Doing high-temperature remediation is not a simple task but done correctly, you can reach amazing results. We will touch on challenges, pitfalls and lessons based on our 20 successfully completed high-temperature project.

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.

In this webinar, Vice President of Thermal Technology John LaChance will briefly introduce the primary ISTR technologies, their applicability, and their primary removal mechanisms at MGP sites. He will discuss the key design considerations for varying conditions and remedial goals, and present a real-life example of an MGP site that was recently remediated with ISTR – including analysis and discussion of the potential role in situ smoldering may play at some sites in the removal of creosote/coal tar. John will also cover projects where the goal was not complete removal but volatilization of the low boiling point compounds and in situ immobilization of the high boiling point compounds, such as heavier range TPH and PAHs.

What do coal tar, PAHs, PCBs, pesticides, dioxins, PFAS and mercury all have in common?

They’re all recalcitrant chemicals that are hard to treat using traditional remediation methods. Sites with these contaminants are nearly unaffected even by thermal treatments reaching the boiling point of water. Luckily, high temperature thermal conductive heating (TCH) can reach temperatures of more than 300°C, high enough to address these difficult chemicals.

In this webinar, TerraTherm’s Steffen Griepke will discuss where high temperature thermal is applicable, what chemicals can be targeted and what results can be achieved. Different implementation approaches tailored to the site specific circumstances will be presented, and both in situ and ex situ case study examples will be provided. Steffen will draw on TerraTherm’s 25 years of experience working with high temp thermal projects to answer participant questions during the Q&A.

If you have interest in cleaning up some the most difficult chemicals out there, this is a webinar you don’t want to miss.

Many promising Pump & Treat Technologies are promoted to treat PFAS in groundwater which is excellent to reduce the risk of further spreading. However, no technologies have been applied to eliminate PFAS source zones so far.

Join three experts from TerraTherm and our European partner KrugerVeolia when they address the topical issue: Is it possible to remove the source totally and permanently?

You will learn:

• How do you analyze PFAS – a family with 3000+ members
• What are the lowest and the most optimal temperatures for removing PFAS
• What is the fate of the fluorine
• Which lab tests and full scale projects have been performed worldwide
• What to look for and what to avoid in terms of successful remedy of PFAS source zones

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.
