Commercial lot with contaminated soil

[Logan Krutsch]

Hello BP,

I am looking at a 6 acre lot to develop a self storage facility on. The problem is the land has been contaminated due to fuel tanks leaking from a gas station next door as shown on the phase II soil survey. The owners of the gas station are aware of the contamination and are not willing to cooperate in any way. The land is also next to a quarry and is likely gravel (which would make construction easier but could also mean the contamination is very deep). It is possible that over 1 acre of the land is contaminated but we will find out after the second soil survey is finished to determine the size of the contamination. I am wondering if anyone has any experience or stories dealing with contaminated soil and how I would estimate the costs to remediate. 

Any advice or help is appreciated,
