An apparatus for high volume in-situ treatment of contaminated soil is a mobile vehicle with a chain trenching tool an excavator drums attached to the idler wheel to extend the width of soil cutting and increase the volume of soil being churned and treated in-situ. The drums may be arranged both for clock-wise and counter clock-wise rotation, and oriented to provide vertical lifting and swirling of the soil. The apparatus may include a hood disposed over the cutting drums to define a remediation chamber with ports for injecting high temperature air or chemical or biological remediation fluid into the soil. In a preferred embodiment, the hood has internal partitions that create a vapor recovery chamber outboard of the drums.
