How to Manage and Optimize the Cost of Your ISTR Project

Originally broadcast on Nov 15, 2022

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.
