Webinars

Join a webinar that will take you on a journey through the transformative efforts at the former Williams Air Force Base in Mesa, Arizona, a former Liquid Fuels Storage Facility (ST012) Superfund Site, where historic releases of JP-4 jet fuel culminated in an estimated spill of 1 to 11.1 million gallons of contaminants.

The site underwent a comprehensive three-stage remediation approach, commencing with the world’s largest Steam Enhanced Extraction (SEE) project, followed by Enhanced Bioremediation (EBR), and concluding with Monitored Natural Attenuation (MNA). This session will shine a spotlight on the monumental first stage – SEE.

The project’s magnitude brought forth a myriad of challenges, from selecting equipment capable of withstanding extreme conditions and high contaminant loads to evaluating pumping systems able to extract hot steam, contaminants and water from up to 240 ft bgs. Delve into how the team navigated these obstacles and innovatively utilized the recovered LNAPL as a sustainable auxiliary fuel source for the vapor treatment system. The presentation will unveil the outcomes of the SEE phase, emphasizing the ingenious strategies implemented to overcome the challenges during the design and operation at ST012.

Join us for this presentation of the world’s largest steam jet fuel remediation project, and the challenges encountered during design and operation of the SEE system. Whether you’re an environmental aficionado, an academic, or intrigued by groundbreaking sustainable practices, this webinar is a treasure trove of insights.

Dive into the groundbreaking remediation techniques of the “Williams AFB SEE Project,” hosted by industry expert Steffen Griepke, VP of Technology at TerraTherm and Stuart Pearson, Principal Environmental Engineer at WSP.

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. 

Is it possible to remediate PFAS contaminants? Our research and experience indicate that it is indeed possible using high-temperature thermal remediation, although there are important factors to consider  to ensure complete removal and treatment of not only target PFAS but also non-target PFAS such as precursors. In this webinar, we dive into the science of using thermal remediation to treat soil contaminated with PFAS and explore the use of our proven high-temperature thermal remediation technology, where soil temperatures ranging from 350 to 500 degrees Celsius are maintained to achieve stringent cleanup levels. Through our research, which we will share during the webinar, we were able to close the fluorine mass balance and determine the fate of the PFAS compounds during thermal treatment.  This allowed us to assess the effectiveness of high-temperature thermal remediation on the removal of PFAS from soil and to design appropriate off-gas treatment systems to ensure that the potential to emit both target and non-target PFAS, including fluorinated hydrocarbons like CF₄ and other significant greenhouse gasses, are appropriately managed.

The treatment of sites with recalcitrant semi-volatile organic compounds (SVOCs) such as PFAS, PCBs, dioxins, and PAHs can feel daunting. A lot of times it seems like the only option is to dig them up and dispose of them in a landfill.  But this presents real long-term liability risks for clients.  Fortunately, there’s an effective on-site solution for treating soil contaminated with SVOCs – high temperature thermal Remediation.

In this flash webinar, TerraTherm thermal experts Erin Hauber, Senior Technologist, and John LaChance, Vice President of Development, will provide a brief overview of thermal remediation and how it removes and/or destroys SVOCs in soil.  They will also explain why thermal conductive heating (TCH) is the primary ISTR technology for the remediation of high boiling point chemicals. They will also discuss how TCH is used for In Pile Thermal Desorption (IPTD) of SVOCs, important design do’s and don’ts for a successful remedy, common ISTR myths, and typical costs.

Add heat to remediate!  Sounds simple enough, but do you ever wonder how raising the temperature can be so effective at removing volatile organic compounds (VOCs) from soil and groundwater, even from difficult-to-remediate low-permeability silts and clays?

TerraTherm technology experts Nikole Huard and John LaChance introduce the primary thermal technologies and mechanisms responsible for this amazing feat.  Key site information useful in evaluating whether In Situ Thermal Remediation (ISTR) is the best option for your site will also be covered.  They  review:

• Important design do’s and don’ts for a successful remedy,
• Common ISTR myths, and
• Typical costs for ISTR at a VOC site.

There were interesting questions at the end of this session so make sure to listen all the way through. This recorded flash webinar is 30 minutes.

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.

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.

Although Steam Enhanced Extraction (SEE) may not be the most common thermal remediation technology, it is the go-to approach for heating and treating sites with high permeability and groundwater flux. Did you know it’s also the most cost-effective way to input energy into the subsurface?

In this 30-min webinar, two thermal remediation experts will give you an overview of SEE. You will learn:

• How SEE works,
