Hi being the vapor, I would guess that my topic would be self evident! However, vapor intrusion has been quite a long time before it became an environmental buzz word in the recent past. I would ask your Brownfield types to use some technical knowledge and common sense in evaluations of vapor intrusion rather than some complciated and generic flowchart that does not reflect reality. As they said at a recent forum held in my honor in Philadelphia: "Use multiple lines of evidence" that would include modeling but not limit the potential based on theoretical modeling rather than data.

I am the true vapor accept no cheap substitutes!
