Vapor intrusion is a potential pathway for human exposure to subsurface contamination. Vapor intrusion occurs when volatile compounds migrate from contaminated groundwater or soil into the indoor air of an overlying or nearby building. Vapor intrusion can result in human exposure to vapor-forming chemicals, such as volatile organic compounds (VOCs) and some other organic and inorganic compounds, which may pose a potential health risk.
