Normal soil remediation is to take a vacuum truck to suck up the pool of oil and then just dig out the contaminated soil.

It may have seeped into the ground water over the years to be sure, but the trenches at the lumber yard were well above the water table. The system as I understood it was to pull the fumes out being diesel & gasoline, which would vaporize more so than say oil.
Years later while working for the City I was assigned a 12" watermain install project on the street the lumber yard was on. One of the sampling wells was in the road and long abandoned, just not properly being left in place with no grout fill or anything to signal it was no longer in use was right in the proposed lines path. When the contractor called the 811, underground service alert it was not claimed or marked by its "owner". With my local knowledge I went into the lumber, they dug up their file and told me the name of the company who did the onsite remediation, so I was able to have the encroachment permit for the sampling well pulled up. My project manager reached out to them, some 20+ years later notifying them as to what they wanted to do. Crickets, we dug through it and paid the water installer under change order to grout infill it and trenched on by.
The city should have paid me a ton more for all of local knowledge having grown up there.
