Future effect of adjacent land contamination

[Clay W.]

I am evaluating the purchase of a former gas station pad that has long since been demolished and paved over. There has also been awarded a No Further Action letter related to years of monitoring after cleanup. However, there is an operating gas station across the street that has an underground "plume" that affects the dirt underneath the subject pad. The company that operates the gas station is supposedly paying for the ongoing vapor/soil testing, etc. I know some investors that run from anything having to do with current or former environmental issues while I know others that find a way to deal with it. I'd like to know how much weight an NFA carries with the subject pad and what I have to worry about in the future if a case then resumes related to my soil even though it would likely be determined that the neighboring gas station was responsible. Are there reasonably priced environmental insurance policies that I could pay for that would over future liability given that the land now has NFA status? --Thanks
