What is Vapor Intrusion?
Chemicals from places like refineries, gas stations, landfills and dry cleaners can contaminate nearby soil and groundwater. When chemical vapors travel from contaminated soil and groundwater into the indoor air of homes and buildings, this is called vapor intrusion. Vapor intrusion may cause health problems depending on the chemical and level of exposure.
