SOLUTION
Treatment Method |
In-Situ Thermal Desorption |
Treatment program |
Treatment of 420 m³ over two batches using 90 heating tubes (propane, natural gas and diesel burners), target temperature of 250°C
|
Contaminated Vapors Management | Vapors captured and treated using the Reburn system, with continuous emission monitoring using gas analyzers |
Process control |
21 temperature monitoring wells, 8 pressure wells and continuous emission measurements ensured optimal heating performance and compliance throughout the treatment |
RESULTS
✅ Soil and groundwater remediation targets successfully achieved (TPH <300 mg/kg in soil and <300 µg/L in groundwater) |
✅ Cross-contamination from soil to groundwater successfully eliminated |
✅ Demonstrated the efficiency of ISTD using multiple fuel sources and Smart Burners® technology |
