Getting Started with Thermal Remediation
January 29, 2025 | 10:00 AM Pacific / 1:00 PM Eastern
In this first webinar of our series titled “The Nuts and Bolts of Thermal Remediation,” we will introduce the fundamentals of thermal remediation, covering the key contaminant removal and destruction mechanisms as well as the primary thermal technologies available. We will explore the benefits and limitations of each technology in relation to site geology and hydrogeology, addressing conditions like above and below the water table, high permeability / high groundwater flow settings, fractured bedrock, and complex sites with mixed permeability layers.
We will also cover the three basic thermal treatment approaches: low (35 to 90°C), moderate (100°C), and high temperature (greater than 100°C), discussing their sweet spots, what contaminants can be treated with each, and why you would choose one over the others. The session will wrap up with a case study demonstrating how multiple thermal technologies were successfully combined to effectively treat a CVOC DNAPL site with both low and high groundwater flow conditions.
Using Conceptual Site Models to Guide Thermal Technology Choice
February 26, 2025 | 10:00 AM Pacific / 1:00 PM Eastern
In this second webinar of our series, “The Nuts and Bolts of Thermal Remediation,” we will take a deep dive into evaluating a site’s Conceptual Site Model (CSM) and selecting the optimal technologies and approach to achieve remedial objectives.
We will review the primary thermal technologies, detailing how each works, and discussing their advantages and limitations across a range of geologic and hydrogeologic conditions, including clay, silts, sands, gravels, bedrock, and varying groundwater flow.
Next, we will outline the key data from a site's CSM that determines technology selection, including:
- COC(s) chemical and physical properties
- Remediation goals
- Depth and volume of contamination
- Geology and groundwater flow
- Presence of underground structures or utilities
- Geotechnical considerations
Finally, we will explore how high resolution site characterization (HRSC) and precise source zone delineation can streamline your project, reduce costs, and ensure successful cleanup outcomes.
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.
Key Steps for Installation of Thermal Remediation Systems
May 28, 2025 | 10:00 AM Pacific / 1:00 PM Eastern
As the design of your thermal remediation project nears completion, it is time to start planning for system installation and construction. In the 5th webinar of our six-part series, “The Nuts and Bolts of Thermal Remediation,” we will cover the key steps to ensure a successful wellfield installation and system construction program.
We will discuss what’s needed to prepare your site for safe and efficient drilling and well installation, including:
- Utility locating
- Clearing and abandonment
- Rig access and sequence planning
- Managing overhead utilities
- Drilling inside buildings
- Investigation Derived Waste (IDW) screening and handling
- Oversight and logging
- Opportunities to collect contaminant data and refine the site CSM during installation
Additionally, we will cover the essential aspects of installing the extraction and treatment systems, along with the power supply equipment. This includes materials and equipment off-loading and staging, determining equipment size and location, placing the power drop, primary transformer, and power distribution and control panels; and managing any site access challenges.

Heat It Up: How High Temp Thermal Tackles Recalcitrant Chemicals
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.
If you have interest in cleaning up some the most difficult chemicals out there, this is a webinar you don’t want to miss.
Thermal Remediation of High Mass Hydrocarbon Sites: When NAPL Capture Governs the Mass Recovery
On sites with contaminant masses counted in the hundred-thousand to million pound range, it’s imperative you choose the right technology for your remedy.
Thermal Technologies are widely used to target high mass contaminated sites where non-aqueous phase liquids (NAPLs) are known to be present. While the geology and hydrogeology of a site typically is a driving factor for technology selection, the mass distribution, chemical composition and thermal behavior for the site contaminants are often the key drivers in determining in which phase the mass is mobilized, and thus the extraction strategy. For VOCs, mobilization in the vapor phase typically fully governs the mass removal. However, for more complex mixtures of high boiling point hydrocarbons, that may not be the case.
In this webinar, Technology Director Steffen Griepke explains what to consider when selecting and designing your thermal remedy for optimized mass removal. He shares best practices and examples drawn from the two decades he worked in thermal remediation.
Real-Time Solutions to Unexpected Challenges Encountered During Thermal Remedy Implementation
An in situ thermal remediation (ISTR) design may look good on paper, but how will it perform in the field?
Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) are widely used thermal technologies capable of effectively remediating a variety of chemicals in various varying subsurface settings, yet sometimes operations do not perform as planned. Due to the aggressive nature of thermal remediation in parallel with pro-active monitoring, operational challenges must be addressed immediately, typically within days rather than weeks. Lessons learned from more than 100 full-scale TCH, ERH and SEE projects will be discussed, focusing on common operational challenges that arise during full-scale thermal projects.
