  • Vapor Intrusion: A hidden danger

    As public awareness has increased, the issue of vapor intrusion in buildings has become a significant environmental concern for building occupants, regulators and industry leaders. According to the EPA, the potential health issues vary and are dependent upon the types of chemicals and concentrations of the chemicals as well as the length of the exposure and the overall health of those that are ...


  • 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 ...
