  • Vapor Intrusion Update

    Vapor intrusion (VI) is a process by which chemicals in soil or groundwater migrate to indoor air above a contaminated site. VI first hit the regulatory scene in 1993 when people began to first realize that this was a primary pathway to be exposed to suburface contamination. As a result, requirements were initally ...

  • CMT simplifies Vapor intrusion monitoring

    Vapor intrusion refers to the movement of volatile chemicals from the subsurface into the indoor air of overlying buildings. The most common source is groundwater or soil contaminated with volatile organic compounds (VOCs). VOCs emit vapors that migrate into pore spaces of the soil and upward into the overlying environment. Generally, vapors enter buildings through cracks and openings in the ...
