An in situ thermal remediation (ISTR) design may look good on paper, but how will it perform in the field?
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. Due to the aggressive nature of thermal remediation in parallel with pro-active monitoring, operational challenges must be addressed immediately, typically within days rather than weeks. Lessons learned from more than 100 full-scale TCH, ERH and SEE projects will be discussed, focusing on common operational challenges that arise during full-scale thermal projects.
