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 prerecorded webinar, thermal expert John LaChance will discuss how thermal technologies can quickly and efficiently remediate contaminated sites for reuse. He’ll discuss some of the challenges specific to former industrial sites and 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.

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.

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.

How can you make thermal remediation more sustainable?  Doesn’t it use a lot of electricity or other fuels to heat the subsurface and doesn’t it require lots of drilling and materials like steel and concrete for construction and operation?  In this webinar, we discuss how we use advanced design, construction, and operations techniques to reduce the carbon footprint of thermal remediation and make it more sustainable.

As you know, In Situ Thermal Remediation (ISTR) is highly effective at quickly cleaning up contaminant source zones, including DNAPL such as Chlorinated VOCs (CVOCs), and even semi-volatile recalcitrant contaminants such as PCBs, dioxins, PAHs and PFAS.  But ISTR requires energy to heat up the soil and groundwater,  volatize the contaminants, and drilling & installation of the energy delivery wells (e.g., heaters, electrodes, and/or steam injection).

In this webinar, we will discuss how we have optimized specific design aspects of our ISTR systems to reduce the amount of power and fuel required to heat and achieve the remedial goals, including:

• Use of numerical models to develop targeted heating strategies and advanced wellfield layouts and heating designs,
• Design of heaters and electrodes that are capable of precisely targeting the treatment interval,
• Incorporation of insulated vapor covers over the ISTR wellfields and
• Use of sophisticated operational strategies to get the most out of the energy delivered to the subsurface for heating and contaminant removal.

So, please join us for an informative look and discussion on how thermal remediation can be optimized to reduce its energy usage and carbon footprint. And importantly, there will be time at the end of the presentation for your questions, so bring them on!

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.

Join this webinar where our Vice President of Development, John LaChance discusses:

• Primary ISTR technologies, their applicability, and primary removal mechanisms at MGP sites
• Key design considerations for varying conditions and remediation goals
• A case study of an MGP site remediated with ISTR, including:
  • Analysis and discussion on the potential role of in situ smoldering in the removal of creosote/coal tar
• Insights into projects with unique goals, such as
  • Volatilization of low boiling point compounds
  • In situ immobilization of high boiling point compounds, including heavier range TPH and PAHs.

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 ETDSP^TM, 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.
