There has been a rapid rise in the need for soil vapor intrusion (SVI) assessments to meet environmental compliance requirements regarding brownfields development and asset improvement in both the commercial and private sectors of the marketplace. As these requirements become more pervasive throughout the country, planners and stakeholders are approaching environmental professionals for solutions. Our approach to SVI sub-slab testing for existing structure interiors incorporates a tracer gas monitoring technique that has proven to be very cost effective. This method allows for the verification that the sample collected from beneath an impervious surface is truly isolated from the ambient air inside the building. Implementation of this method has met with the approval of New York regulators and is consistent with their Soil Vapor Intrusion Guidance, which was published in 2005.
