Full-Scale In-Situ Thermal Desorption of Hydrocarbon Contamination at the Ford Aquitaine Industry Site in Blanquefort, France

A 1,260 m³ full-scale remediation used 48 heating wells to treat HCOV trapped in a floating mineral-oil layer, with vapour condensation and activated-carbon treatment, achieving the remediation objectives after five weeks of heating.
