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.

What is Thermal Remediation?

Are you in need of a solution for a site with contaminants that are hard to treat, an aggressive schedule, and/or stringent cleanup goals? If so, then thermal remediation may be a strong candidate for your site.

In this 30-minute flash webinar, Senior Technologist Erin Hauber and Senior Chemist Alyson Fortune will cover the basics of thermal remediation. They will introduce the three primary thermal technologies, Electrical Resistance Heating (ERH), Thermal Conduction Heating (TCH), and Steam Enhanced Extraction (SEE). They will explain how they work, the key removal mechanisms, and what constituents & lithologies they are best suited to treat.

If you’re interested in gaining a basic understanding of thermal remediation and how it can be used to remediate source zones, this webinar series is one you won’t want to miss. Watch the webinar-on-demand today!

What is Electrical Resistance Heating (ERH) and How is it Applied?

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.
