Does anyone know if the phase 1 assessment checks for radon? I've heard that could cause cancer as well...or are we talking about the same thing here? Thanks.

Hi Alphazulu, many Phase I Environmental Site Assessments do have a screen for radon (each area of the country is assigned a risk level for radon and most Phase Is note this risk level), but sampling for radon can be easily included in the scope of a Phase I if requested. Vapor Intrusion, however, usually refers to non-naturally occurring vapors that originate from contamination beneath the property.

Oh and yes, radon is a carcinogen.

This is the very important thing for the real estate investors to know about the vapor intrusion. As somebody suggested that it is the non natural thing beneath the property So, I think the investors should keep in mind about this before investing.
