SITE DESCRIPTION
Treated Volume | 1,260 m³ of contaminated soil (2,268 T) |
Thermal technology | In-Situ Treatment (ISTD, full scale) |
Main contaminant | Hydrocarbons (HCOV), including perchloroethylene |
Site challenges | Hydrocarbons trapped in a mineral oil layer floating on groundwater, over a 280 m² area at 4.5 m depth |
Project Timeline | 2011 |

SOLUTION
Treatment Method |
Full-scale In-Situ Thermal Desorption following a successful pilot test |
Treatment program | 48 heating wells connected to 24 gas-fuelled burners |
Contaminated Vapors Management | Condensation and cooling, then activated carbon treatment |
Process control | 5 weeks of treatment · continuous monitoring of temperature, air quality and gas emissions |

RESULTS
✅ 1,260 m³ of contaminated soil treated (full scale). |
✅ Remediation objectives achieved for hydrocarbons trapped in the floating oil layer |
✅ Project delivered for Ford Aquitaine Industry with consultant APAVE |
