  • Modulo for Vapor Intrusion

    The system creates an under slab void that works as a capillary barrier against moisture - yet uses less concrete than other standard slab equivalents but has, at the same time, a superior load bearing capacity. This is also a “green” building product that will lower future electrical costs and contribute to LEED points on sustainable building projects. Moreover, Geoplast’s ...

  • 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 ...

  • Vapor Intrusion Issues Concern Nebraska Residents

    Nebraska health officials identified volatile organic compounds (VOCs) in the water wells of Columbus, NE in 1983. Beginning in 1987, the U.S. Environmental Protection Agency (EPA) began implementing procedures to reduce the levels of tetrachloroethylene (PCE) that were found in the area.   Recently, the EPA announced plans to tear down several businesses to speed up the remediation process ...

  • Vapor Intrusion Risks a Real Threat to Building Occupants

    Vapor intrusion is the process by which chemicals migrate to the indoor air above a contaminated site.  Vapor intrusion generally occurs when there is movement of volatile chemicals from contaminated groundwater or soil into an overlying building. In extreme cases, the vapors may accumulate in dwellings or occupied buildings to levels that may pose near-term safety hazards from explosions, ...

  • California Residents Concerned over Trichloroethylene and Vapor Intrusion

    Last month, Palo Alto’s Mountain View Voice published a story about concerns over toxic chemicals at a former military housing complex.  The focus has been on Orion Park ever since trichloroethylene (TCE) has been found in the groundwater and from air samples taken from buildings on the site.  The TCE is believed to have contaminated the area from its years of military use.  ...

  • Vapor Intrusion, an Invisible Threat to Building Occupants

    In 1970, over a dozen railroad cars left their tracks in Leroy, New York.  Several ruptured containers held trichloroethylene, also known as TCE.  An estimated 30,000 to 35,000 gallons of the chemical spilled to the ground.   The TCE that spilled has made its way into the ground across the area prompting officials to perform vapor intrusion testing in a number of homes decades ...

  • CMT for high resolution vapor intrusion monitoring

    Background 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 ...
