Thermal Remediation of MGP Sites, From Strategy to Real-World Performance
Former manufactured gas plant (MGP) sites present some of the most complex remediation challenges, driven by coal tar DNAPL, high contaminant mass, and difficult subsurface conditions that limit the effectiveness of conventional approaches.
This two-part webinar series explores how thermal remediation is applied to address these challenges, from initial evaluation and system design through real-world implementation and performance.
In the first session, attendees will learn how thermal remediation targets coal tar source zones, performs in low-permeability soils, and supports efficient cleanup aligned with regulatory and redevelopment goals. The webinar focuses on key design and implementation considerations, including contaminant profiles, treatment depths, and strategies for managing large contaminant mass, along with how thermal technologies can be integrated with complementary remedies to strengthen overall performance.
The second session builds on these concepts through case studies that demonstrate how thermal remediation systems perform under actual site conditions. Drawing on multiple projects, this webinar walks through the full implementation lifecycle, highlighting how teams have navigated complex subsurface conditions, adapted to field challenges, and achieved successful outcomes.
Together, these sessions provide a practical, field-driven perspective on applying thermal remediation at MGP sites and offer insights that support more informed, defensible remediation strategies.
In this two-part series, you will learn how to:
- Evaluate when thermal remediation is the right fit for MGP sites
- Apply key design and implementation strategies for coal tar source zones
- Manage high contaminant mass and complex subsurface conditions
- Connect site data to technology selection and system design
- Navigate field challenges and adapt during implementation
- Benchmark real-world performance to support defensible decisions
- Soil Sampling Fundamentals: Methods, Tools, and When to Use Them

Which is Better? Electric Resistance Heating (ERH) or Thermal Conduction Heating (TCH)?
Electric resistance heating (ERH) and thermal conduction heating (TCH) have many similarities, and it can be hard to figure out which one is best suited for a specific project site. It’s critical to know the pros, cons, and differences of each because making the wrong call on technology selection can have expensive repercussions.
In this 30-min webinar VP of Development, John LaChance and Senior Technologist, Erin Hauber will give you a quick overview of the basic operational theory and concepts for both technologies and discuss their application to a set of typical site conditions. The webinar will focus on the pros and cons for each technology combined with real-life examples of full-scale TCH and ERH projects, including detailed breakdowns and comparisons of costs.
If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.

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. They will provide several examples of projects where thermal technologies have been successfully combined.
Join the discussion for insight on how and when to combine thermal technologies to treat sites with varied and complex conditions. There will be time at the end for Q&A, so bring your questions about using thermal to remediate sites.

How to Manage and Optimize the Cost of Your ISTR Project
Why do thermal remediation projects cost so much? And is there anything that can be done to manage those costs?
In part one of this webinar series, TerraTherm experts Erin Hauber and John LaChance explained how in situ thermal remediation (ISTR) costs are determined.
In this second, 30-minute installment, they shared ways to manage the cost of ISTR and discussed how decisions made during the site characterization, technology selection, procurement, and design phases of a project impact costs. They also covered…
- Establishing the treatment area and interval
- Soil and water cleanup goals (e.g., what happens when the cleanup goal within the treatment area is much less than concentrations remaining on the outside)
- Starting mass estimates
- Subsurface vs. above grade wellfield completions
- Conservative temperature performance goals (e.g., every sensor must achieve 100°C).
Erin and John provided guidance on how to compare competing proposals to identify the best technical approach and overall value, giving you and your client the highest probability of success for the minimum cost.
Why Do Thermal Remediation Projects Cost So Much?
Ever wonder why using thermal remediation technology costs so much? Are owners of thermal remediation companies driving around in fancy cars and vacationing on the Riviera (or fill in the blank for some other nice spot)?
As hard as it may be to believe, the answer is no. In this two-part flash webinar series, our experts will delve into the details that determine in situ thermal remediation (ISTR) project costs, and how those costs can be managed.
In part one, TerraTherm experts Erin Hauber and John LaChance will explain all the moving parts that go into the delivery and implementation of a successful ISTR project. They’ll pull the curtain back and break down the components of a thermal project (drilling, surface cover, vapor and liquid extraction, manifold piping, treatment system, power supply, and design, operations, engineering support, etc.) and how site conditions (COCs, depth of treatment, geology, groundwater flux, and site access limitations) affect design approaches and costs.
You’ll also have a chance to ask your most burning questions about thermal remediation costs, so be sure to register and attend!
ISTR Challenges Part 2: Electrical Resistance Heating and Steam Enhanced Extraction
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.
