Environmental soil pollution can enter buildings through a process called vapor intrusion. Vapor intrusion is the migration of volatile organic compounds (VOCs) that have high vapor pressure and low water solubility. They can be present in contaminated soils or groundwater.
Volatile organic compounds are produced and used in the manufacture of fuels, paints, pharmaceuticals, and refrigerants. VOC's are also present in industrial solvents, paint thinners, tetrachorethene (TCE, which is dry cleaning fluid), fuel, oxygenates (MTBE), or chlorination in water treatment systems.
When these contaminants are present in the soil there is potential for vapor migration through the surface soils into surrounding buildings, thus potentially impacting the indoor air quality and posing a health risk to the building inhabitants. This exposure is receiving increased attention by regulators, in many states and represents a significant liability risk for building owners in an evolving regulatory climate.

Since hazardous vapor intrusion into buildings is often associated with soil contamination, the Environmental Protection Agency has done considerable research in this area. The EPA provides basic information about vapor intrusion as well as detailed guidance for vapor intrusion mitigation (also called soil vapor extraction). This EPA vapor intrusion guidance is important for all people throughout the United States to accept and use to take action.
The most common solution is to install systems often used to reduce naturally occurring radon that seeps into building in some geographic areas. These systems, called radon mitigation systems, remove soil vapors from below basements or foundations before they enter the space.
As your local vapor intrusion experts, we can provide you with several quality soil vapor extraction options, including:
We can also install vapor pins for diagnostics and annual maintenance. The vapor pin is a reusable sub-slab soil gas sampling device. The vapor pin is constructed of a single piece metal. This single piece design along with the silicon sleeve eliminates potential leak points. It is installed to provide a sealable measurement point for annual maintenance of the system.
