Thermal Remediation

July 8 @ 12:00 pm - 2:00 pm

In situ thermal remediation (ISTR) has gained wide acceptance over the last 20 years, and it has been used successfully on projects all over the world. ISTR is used to reduce the source of contamination by heating subsurface groundwater and the vadose zone to facilitate volatilization or other contaminant removal mechanisms.  The three major ISTR technologies are the following:

  1. Thermal Remediation: Steam – Steam is generated at the surface and injected into wells, sweeping to extraction wells for liquid and vapor removal.
  2. Electrical Resistance Heating – Electrodes deliver electricity and water to the subsurface, and heating occurs in the subsurface. Vapors are typically extracted either from the electrodes or from separate extraction wells.
  3. Thermal Remediation: Desorption – ISTD is also called Thermal Conduction Heating, combined with fluid extraction. Simple heater borings transfer heat (no fluids) to the subsurface, and chemicals are extracted from liquid and vapor extraction wells.

Technology selection depends on specific site conditions, contaminant properties, and remedial objectives. At many sites, thermal technologies can be combined with less aggressive remediation methods for complete site and plume restoration (e.g., see Thermal Remediation – Combined Remedies).

Rob D’Anjou and Jim Cummings are considered global leaders on these technologies and they will be teaching you more about how to use the correctly for your next project.
