SITE DESCRIPTION
Treated Volume | 3,648 m³ of contaminated soil
|
Thermal technology |
In-Situ Thermal Desorption (ISTD) |
Main contaminant |
Trichloroethylene (TCE) |
| Site challenges |
Urban brownfield requiring remediation to an extremely low cleanup target (<1 mg/kg) |
Project Timeline | Jan - May 2025 |
SOLUTION
Treatment Method |
In-Situ Thermal Desorption |
Treatment program | 135 heating tubes, 135 Smart Burners, 11 MPE wells, VTU/CTU vapor treatment with continuous temperature monitoring. |
Contaminated Vapors Management | Extraction through MPE wells with treatment by VTU/CTU before atmospheric discharge. |
Process control |
Continuous monitoring using thermocouples to control subsurface temperatures during heating. |
RESULTS
✅ 99% of TCE removed from contaminated soil. |
✅ 3,648 m³ (6,564 tonnes) treated using ISTD technology. |
✅ Most of the treatment area achieved significant contaminant reduction; the remaining hotspot was scheduled for excavation to meet the client's stringent cleanup target (<1 mg/kg). |
