Webinar: Thermal Treatment: A Reliable Option For Your Bedrock Source Zone

Treating fractured bedrock is complex, and effective remedial options are limited. Due to the fractured nature of rock, contamination can migrate deep, and pathways out of the bedrock system are limited.

One of the most effective and reliable methods of treating fractured bedrock is to use thermal technologies.

In this webinar, presenters Steffen Griepke, Technology Director at TerraTherm and Niels Ploug, Product Manager at Krüger will discuss the treatment of bedrock source zones, including:

  • The challenges of removing volatile organic compounds (VOC) from fractured rock
  • The pros and cons of the most common thermal treatment technologies in bedrock settings
  • Design considerations and field implementation challenges

The presentation will be peppered with examples and results from the many thermal sites successfully treated by the combined TerraTherm and Krüger teams. Steffen and Niels will also share highlights from a recently completed project—the world’s deepest thermal remediation project of crystalline rock, treated to a total depth of 170 ft.

Webinar: Recalcitrant Contamination: Challenges, Pitfalls and Learnings from 20 High-Temperature Projects

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.

Webinar: 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.

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.

Webinar: Heat It Up: How High Temp Thermal Tackles Recalcitrant Chemicals

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.

Webinar: 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.

Webinar: 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.
