Many Vapor Intrusion guidance documents encourage analyzing a short list of comhttp://www.blogger.com/img/blank.gifpounds in indoor air -- for example, instructing the lab to report only the compounds detected in subsurface samples during previous related investigations. But be careful! As vapor intrusion assessment moves toward indoor air sampling, analyzing only for a short list of compounds could come back to bite you.

I agree with the post. . can natural gas affect the behavior in the environment. because that was part of my study...thanks
