Webinars

Thermal remediation at sites with complex geologies where there are both high and low groundwater flow zones requires innovative engineering and a multi-technology approach to achieve success. The Hamilton/Labree Roads superfund site presented such challenges, including a PCE DNAPL source zone beneath a road and a creek, complex hydrogeologic conditions, and high groundwater flux zones. In this webinar John LaChance, VP of Development at TerraTherm will cover:

• Detailed Site Model: Understand the importance of a detailed conceptual site model (CSM) and site lithology in designing an effective remedy.
• Comprehensive Approach: Learn how multiple technologies were integrated to tackle the site’s unique complexities and achieve the remedial objectives safely and effectively.
• Technological Implementation: Discover how 49 steam injection wells (SIWs) and 82 ERH electrodes were used to effectively heat the site, and how a variety of extraction systems were used to maintain pneumatic and hydraulic control.
• Innovative Solutions: Explore the engineered solutions used to protect the creek, including an insulated channel and continuous temperature monitoring.
• Proven Results: Review the outcomes of the remediation process, including achieving soil concentration goals and removing over 7,800 lbs of contaminants.

Join us for an in-depth session into the lessons learned during the design, construction, and operation phases of this successful thermal remediation project. Gain valuable insights from real-world applications and understand how to address the challenges of complex geologic systems with high groundwater flux zones.

Over the past 20 years, John has become a leading expert in thermal remediation technologies. He helps clients select the right technology to effectively and efficiently remediate their sites, meet regulations, and ultimately enable property reuse. With over 50 successful in situ thermal remediation projects, John brings a wealth of technical and strategic insight to the thermal remediation field.

When a manufactured gas plant (MGP) site is identified for treatment, the typical remediation approach can be expensive and involve hazards for crews and the community. Any time you excavate contaminated soil and transport it for treatment or disposal, you are introducing potential safety and liability issues. Luckily, in situ thermal remediation (ISTR) is often a safe and cost-competitive alternative.

Join this webinar where our Vice President of Development, John LaChance discusses:

• Primary ISTR technologies, their applicability, and primary removal mechanisms at MGP sites
• Key design considerations for varying conditions and remediation goals
• A case study of an MGP site remediated with ISTR, including:
  • Analysis and discussion on the potential role of in situ smoldering in the removal of creosote/coal tar
• Insights into projects with unique goals, such as
  • Volatilization of low boiling point compounds
  • In situ immobilization of high boiling point compounds, including heavier range TPH and PAHs.

It’s one of the most commonly asked questions when considering thermal remediation, and in this webinar one of the industry’s leading experts will answer it. Join TerraTherm, a Cascade Company’s Vice President John LaChance as he introduces the basic operational theory and concepts for both technologies. He’ll discuss their application to a set of typical site conditions (e.g., low and high permeability zones in unconsolidated and bedrock formations) and contaminants (e.g., CVOCs), and highlight typical design approaches, assumptions, and the pros and cons of each.

John will share real-life examples of full-scale projects involving electric resistance heating (ERH) and thermal conductive heating (TCH), including detailed breakdowns and comparisons of costs. He’ll also touch on ETDSP^TM, a form of ERH that employs active injection and extraction of water. If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.

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.

New to thermal remediation? If so, understanding how the technologies work and how to choose the best one for your project can be overwhelming and confusing. Each heating technology has its own strengths and weaknesses depending on the site conditions and contaminants of concern.

In this 30-minute flash webinar, our VP of Development, John LaChance, and Senior Technologist, Erin Hauber, will give you an overview of Electrical Resistance Heating (ERH). You will learn:

• How ERH works,
• What geologic conditions it is best suited for,
• What contaminants it can treat,
• Design considerations to ensure a successful ERH project, and
• ERH sweet spots.

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.  An experienced thermal remediation contractor can help you anticipate and address site-specific challenges during full-scale thermal projects.

Presented by Vice President of Development, John LaChance and Vice President of Technology, Steffen Griepke, ISTR Challenges Part 2 covers some of the common issues that can arise at ERH and SEE sites, and discuss how they should be addressed.  You’ll hear about scenarios involving

• significantly different soil electrical resistivities than planned
• slower than expected heat-up
• stray voltages and currents
• poor steam quality
• higher than expected mass removal rates
• lack of hydraulic control
• non-uniform steam delivery and heating

Join the discussion for insight to help avoid costly project delays in your next thermal project.
