What Is Vapor Intrusion (VI)
Vapor Intrusion (VI) refers to the phenomenon in which contaminated soil vapor is created by the off-gassing of volatile compounds in the subsurface (either in soil or groundwater). In certain conditions, these vapors can migrate through the soil column and enter overlying structures through cracks and gaps in basement floors and walls, and through openings for utilities and sump pits.

​Vapor intrusion is a dynamic process; not only in its scientific nature, but also as an emerging environmental concern for which state and federal laws and regulations are still being developed.
Vapor intrusion concerns present new and complex challenges for building owners and operators. Mitten understands that a practical, cost-effective approach to vapor intrusion management can be critical to the success of your project.
