"What you should know about vapor intrusion"
March 9, 2010
The EPA has a useful online fact sheet about vapor intrusion
into homes and other buildings which illustrates how the vapors from chemicals like volatile organic compounds can seep from the groundwater and contaminated soils into habitable buildings. Vapor-intrusion hazards aren't particularly common, though they do occur frequently enough that many large cities have case studies and example sites nearby. In Waterloo, Iowa, for instance, the site of an old coal gasification plant
has been identified as a location where vapor-intrusion controls will be required for future construction. Vapor barriers
are an effective means of reducing the risk of vapor intrusion and can also be helpful for reducing the incidence of hazards like black mold. We are happy to answer your questions about vapor barriers -- just contact us
