ERH And TCH – How To Choose

Date/Time: May 17, 2022 from 1:00 pm - 2:00 pm eastern

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.

Introduction to ISTR – Part 1

Date/Time: April 19 @ 1:00 pm - 1:30 pm EDT

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 first of two flash webinars, thermal experts Nikole Huard and Steffen Griepke will cover the basics of thermal remediation. They’ll explain the key removal mechanisms and how the three primary thermal technologies work and what constituents and lithologies they’re best suited to treat as well as the essential site information required to evaluate whether thermal remediation is a good fit and typical project timeframes.

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.

Brownfield Success: How to Select the Right Remediation Technology For Your Budget and Timeline

The demand for redevelopment in many cities is at an all-time high, and states and federal agencies are responding by increasing funding for addressing brownfield sites. Brownfield sites can be contaminated with several chemicals, ranging from petroleum hydrocarbons to chlorinated solvents and metals. Many sites may also include PFAS or 1,4 dioxane, and traditional technology approaches on these sites could result in costs that would kill the project budget and timeline.

In this webinar, a panel of experts from TerraTherm and Cascade will explain how you can identify the unknowns in your site’s subsurface, and select remediation options tailored to the contaminants present and the turnaround time you need to achieve.

They’ll share case studies, methodologies, opportunities to optimize for cost and time, and explain how, when and why certain technologies may be your unexpected best bets.

Data Management: The Most Underrated Aspect of Thermal Remediation

Because a thermal wellfield is a constantly changing entity with many different characteristics, collecting and managing the right data is essential in a successful treatment outcome. The field data and process numbers we get from collected data reveal trends and details that allow us to optimize our treatment approach, streamlining the path to completion. To gain real-time feedback, our team utilizes the “TerraTherm Insight Portal,” which allows us to optimize the thermal remedy and track important site data, as they are collected.

In this webinar, Anthony Caravella, Instrumentation Engineer at TerraTherm, a Cascade Company, will explain the importance of data management and how it helps to optimize treatment. He will highlight the functions of TerraTherm’s Insight Portal and how it improves the lines of communications between our team and the client. Attendees will also learn about real-life examples of data management from the field.

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.

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.

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.
