Thermal Modeling, Wellfield Design, and Monitoring
March 26, 2025 | 10:00 AM Pacific / 1:00 PM Eastern
In the third session of our webinar series titled “The Nuts and Bolts of Thermal Remediation,” we will review the details of the design of thermal remediation systems, following a thorough review of the Conceptual Site Model (CSM), and the selection of the appropriate technologies and approaches.
Thermal remediation expert, Steffen Griepke will guide us through designing the heating, extraction, and monitoring components of the system. He will also discuss the role of numerical modeling in ensuring effective heating across the treatment zone at all depths and locations as well as in predicting the operational timelines, utility requirements, and equipment sizing.
Some key insights from numerical modeling include estimating electrical power load, electricity consumption, vapor and liquid contaminant loading to the treatment equipment, liquid treatment and discharge rates, and vapor and liquid cooling loads.
We will cover the design of the wellfield components, including the thermal wells (TCH, ERH, SEE), extraction wells, and temperature and pressure monitoring points. This session will also specify which parameters to monitor and at what frequency. Lastly, we will discuss the importance of evaluating whether an insulated vapor cover is needed over the treatment area to ensure effective heating and successful remediation.
Selection and Design of Vapor and Liquid Treatment Systems
April 23, 2025 | 10:00 AM Pacific / 1:00 PM Eastern
Vapor and liquid extraction and treatment systems are essential components of in situ thermal remediation (ISTR). These maintain pneumatic and hydraulic control during all phases of heating to ensure that the contaminants of concern (COCs) are effectively captured and removed from the treatment zone and unwanted mobilization and spreading are prevented.
Once recovered, the COCs must be removed from the vapor and liquid streams for proper disposal. In this fourth webinar in our series titled “The Nuts and Bolts of Thermal Remediation,” we will look at how vapor and liquid extraction and treatment systems are designed.
Presenter Steffen Griepke will draw on his experience to cover:
- Choosing the right treatment technologies for specific COCs and mass levels.
- Special considerations for treating PFAS and 1,4-dioxane.
- The fundamental components of ISTR treatment systems.
- Selecting appropriate materials for vapor manifolds and treatment equipment.
- The role of the mass and energy balance in sizing equipment and in managing the cooling and heating loads.
- Effective strategies for handling non-aqueous phase liquid (NAPL) recovered from the treatment zone or condensed out in the vapor manifold and equipment.

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!
