Bet California doesn't allow that. There are specialists with kit to do this. You truck all the contaminated ground away to them, where a centrifuge-like machine heats it, mixes it with water, splits it into components, etc and deals with it all. Expensive machine, not used that much, so costs a lot when you do. Charged by the ton. Meanwhile, truck back in fresh soil. Old roadside fuel station sites invariably have petrol and diesel which has leaked from the tanks into the ground below and needs this before you build something else there.
