The phrase “soil vapor intrusion” refers to the process by which volatile chemicals migrate from a subsurface source, through soil vapor and into the indoor air of a building where an adverse exposure is possible. Soil vapor, also referred to as soil gas, is the air found in the pore spaces between soil particles (Figure 1). Soil vapor ...

When a group of chemicals known as volatile organic compounds (volatile chemicals) are released into soil or shallow groundwater, these chemicals evaporate, producing vapors that travel up through the soil. These vapors can enter nearby homes and businesses through crawlspaces and cracks or other openings in the foundation. This process is known ...

Volatile organic compounds (VOCs) are present in soil and groundwater at virtually every industrial and commercial facility that ever stored, used, or disposed of fuels or solvents. The potential for VOCs to migrate upward into a building is known as “vapor intrusion” and is now among the highest priorities of EPA and state agencies.

By Cox-Colvin & Associates, Inc based in Plain City, OHIO (USA).

Although air quality issues typically result from direct emissions from exhaust stacks or chemicals used in industrial processes, vapour intrusion is caused by contaminants in soil or ground water volatilizing (evaporating) and moving indoors through the foundation or floor slab. Vapour intrusion, particularly of volatile organic compounds (VOCs), ...
