Vapor intrusion (VI) occurs when there is a migration of vapor-forming chemicals from any subsurface source into an overlying building. The vapors can enter buildings through cracks in basements and foundations, or through conduits and other openings. Examples of vapor-forming chemicals that are hazardous to human health include methane (from landfills), tetrachloroethene (PCE) and trichloroethene (TCE) from dry cleaners, benzene (from petroleum products), and radon.
APPLIED ENVIRONMENTAL has vast experience in conducting VI investigations, interpreting results, and providing cost effective solutions to mitigate the VI exposure pathway.
