Upcoming Webinars
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.

Can Thermal Remediation Technologies be Combined at a Site?
Maybe you have a site with challenging geological features, and you’re trying to figure out if a thermal remediation technology can be used. Or perhaps you have a client who is on a tight schedule and needs to treat a source zone and a downgradient plume simultaneously to develop the site in a short amount of time.
What may come as a surprise is that while each individual thermal technology has its sweet spot, multiple technologies can be used safely at a site simultaneously to address contamination in complex geologies like silts, clays, sands, and fractured bedrock.
In this 30-min flash webinar VP of Technology, Steffen Griepke and Senior Technologist, Erin Hauber will reveal when it’s beneficial to combine thermal technologies to meet the site-specific goals.
