Vapor Mitigation Assessment

In the late 1980s it was recognized that the presence of radon in indoor air was caused by the intrusion of vapors from the subsurface. This recognition resulted in an ever increasing awareness that certain volatile chemicals (petroleum hydrocarbons and chlorinated solvents) in soil and groundwater could also impact indoor air quality as a result of the same pathway pose threats to indoor air quality via the vapor intrusion pathway. With experience in commercial and manufacturing facilities ranging in size from less than 5,000 square feet to more than 5MM square feet, we will gather the data necessary to understand the impacts in the subsurface and the potential for these to impact indoor air quality. We will always use an iterative approach and the most cost-effective characterization tools to get you the information you need, when you need it.
