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.

Complex geologies with highly permeable zones can cause significant challenges while heating the subsurface during in situ thermal treatment, and those challenges pose a serious threat to your project’s success. It is critical to have a detailed conceptual site model (CSM) and a proper understanding of the site’s lithology before choosing the technologies and designing the remedy that will best address the contaminant(s), the site’s unique complexities, and the outcomes demanded by state and federal guidance.

In this pre-recorded webinar, thermal expert John LaChance discusses:

• The characteristics and types of areas with high permeability and complex geological structures.
• The impact of these conditions on the effectiveness of thermal cleanup methods
• Examples of successful thermal cleanup projects in challenging geological settings.

Join us for an in-depth webinar exploring cutting-edge techniques in groundwater source zone contamination treatment. Dive deep into the challenges and potential of thermal remediation at sites with high groundwater flux rates. Discover how Steam Enhanced Extraction (SEE) can be utilized effectively with Thermal Conductive Heating (TCH) or Electrical Resistance Heating (ERH) to optimize heating in high-permeability and high groundwater velocity situations. 

However, thermal treatment of groundwater source zones is not without its challenges. Understand the design considerations and treatment system impacts on high flowing thermal sites, along with the change in energy demand associated with maintaining hydraulic control during the thermal remedy.  Equip yourself with the knowledge to navigate these challenges and implement efficient and cost-effective remediation strategies. 

Don’t miss out on this opportunity to learn from industry experts and enhance your understanding of groundwater source zone remediation techniques. Register today for our next webinar and stay on top of the latest trends and techniques in environmental management. 

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.
