Phase III required (way more than I expected)

[Lesley Cabrera]

So I invested into a property without knowledge of its past (1st mistake) I have already had a phase 1 and phase II completed. Apparently there are pollutants in the soil. Does anyone have any experience with this?. I have gotten 2 different proposals which range so vastly. The lender is requiring me to have this "all cleared" before moving forward.  Any referrals would be greatly appreciated.
