Webinars

“Thermal” and “sustainable” in the same sentence?!

Yes! Although most often associated with a high demand for resources and infrastructure, thermal remediation can be accomplished sustainably.

In this flash webinar, John LaChance and Erin Hauber 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. They’ll also cover which contaminants of concern (COCs) are most suited for this approach, costs, and timeframe.

John and Erin will answer questions during a Q&A at the end of the presentation, so be sure to submit yours during registration.

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.

Using thermal technologies is one of the most effective and reliable methods of treating fractured bedrock.

In this flash webinar, presenters Steffen Griepke and John LaChance, (VPs of Technology and Development, respectively) discuss the treatment of bedrock source zones, including:

• The challenges of removing CVOCs and DNAPL from fractured rock
• The pros and cons of the most common thermal treatment technologies in bedrock settings
• Design considerations and field implementation challenges

This recorded webinar will include examples and results from bedrock sites successfully remediated using thermal. Steffen and John will also share highlights from a completed project—the world’s deepest thermal remediation project in crystalline rock, treated to a total depth of 170 ft.

If you are involved in the evaluation or remediation of any bedrock sites, this is a webinar you want to watch.

More and more frequently, In Situ Thermal Remediation (ISTR) is being used to treat contaminations located below buildings, roadways, and other critical infrastructure. Subsidence and potential geotechnical effects on buildings and infrastructure are concerns often raised in the initial design phase of a thermal remedy.

While the heating approach and main heating mechanisms differ based on the ISTR technology utilized, heating in general will thermally expand the soils treated and at the same time, change the saturation of the treated volume due to boil-off of some of the water. Depending on the geology, this can lead to changes in the geotechnical integrity.

In this flash webinar, the basics factors affecting the geotechnical properties during a thermal remedy will be discussed, along with a general description of soil types where subsidence is more likely to happen. Examples of geotechnical pre-investigations and tests utilized to determine the impact of a structure’s stability will be given along with case studies showing data from thermal areas remediated below structures.

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.

In Situ Thermal Remediation (ISTR) has a reputation as one of the most effective approaches for addressing sites with hard-to-treat constituents, including volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). Want to learn more? This flash webinar will help you understand how ISTR works to accomplish your cleanup goals.

TerraTherm technology experts Erin Hauber and John LaChance will cover the basics of thermal remediation and explain how the three primary ISTR technologies treat VOCs, including BTEX. They’ll also review:

• Key contaminant removal mechanisms
• Important design do’s and don’ts for a successful remedy
• Common ISTR myths
• Indication of typical costs

There will be time for questions at the end,  so bring the thermal remediation questions you’ve never had a chance to ask. This flash webinar is scheduled for 30 minutes.

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; including everything from, VOCs, SVOCs and PAHs to MGP coal tar PCBs, dioxins and even PFAS. But to reliably and uniformly 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 second flash webinar of the series, Nikole Huard and Steffen Griepke will cover how to select the best technology for your site and remedial goals and provide a few real-life examples.

There will be time for Q&A after each webinar, 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 two-part webinar series is one you won’t want to miss.

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.
