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 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.

Improving the Sustainability of Thermal Remediation

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!

The Fate of PFAS During Thermal Remediation

Is it possible to remediate PFAS contaminants? Our research and experience indicate that it is indeed possible using high-temperature thermal remediation, although there are important factors to consider  to ensure complete removal and treatment of not only target PFAS but also non-target PFAS such as precursors. In this webinar, we dive into the science of using thermal remediation to treat soil contaminated with PFAS and explore the use of our proven high-temperature thermal remediation technology, where soil temperatures ranging from 350 to 500 degrees Celsius are maintained to achieve stringent cleanup levels. Through our research, which we will share during the webinar, we were able to close the fluorine mass balance and determine the fate of the PFAS compounds during thermal treatment.  This allowed us to assess the effectiveness of high-temperature thermal remediation on the removal of PFAS from soil and to design appropriate off-gas treatment systems to ensure that the potential to emit both target and non-target PFAS, including fluorinated hydrocarbons like CF4 and other significant greenhouse gasses, are appropriately managed.
