Phase II ESA Question

I’m probably overthinking this but I was hoping to get some feedback on this project I’m working. I usually work large military or industrial sites but I recently took on a small Phase I ESA for a small operation car dealership here in Texas. Only finding was a small concrete pad that stored 55gal drums of oil. There was staining on the concrete pad and a little on the side into the soil.

So I recommend a Phase II to test for presence of petroleum products in the soil. I didn’t think there would be much in the soil, so I offered to cheaply hand-auger a few samples to confirm it wasn’t more than a foot into the soil.

Today I went 4ft down and the entire depth smelt horrible, like a lot of product. I hit refusal due to rock and tree roots, but the soil was still smelling very potent. I imagine it’s all going to come back really hot.

Question: does this go straight to Phase III? Or should I bring in a driller to determine depth of the product in hopes it’s not too deep? Or is 4ft of impacted soil enough to move forward for sure?
