Vapor Intrusion

Vapor Intrusion occurs when chemical vapors from groundwater and soil, migrate into a building from below the surface.

Most Vapor Intrusion events occur when volatile organic compounds (VOCs) are released into the soil from underground storage tanks, dry cleaners, gasoline stations, or industrial processes such as degreasing metals. VOCs have a high vapor pressure which means they can easily move into a gaseous state. As a gas, these chemical vapors can migrate upward into buildings and be inhaled by the building’s occupants resulting in potential health concerns including cancer. The level of the risk depends on the toxicity of the individual chemical and its concentration in the building.

Designing an effective and efficient vapor mitigation system is significantly more complex than a standard radon mitigation system. Proper vapor mitigation requires extensive knowledge of building science, and soil gas mechanics, as well as, environmental extremes and their impact on the air pressure in the building. Clean Vapor has developed a proven four step process: Diagnose, Design, Build, Monitor; to provide solutions and regulatory documentation for clients with vapor intrusion concerns.

Our Process



The first step in creating an efficient Vapor Intrusion Mitigation System (VIMS) is to diagnose your unique set of site-specific variables.
