The primary objective of this demonstration study was to identify a cost effective and accurate protocol for investigation of vapor intrusion into buildings overlying contaminated groundwater. Intensively monitored sites, such as the Borden Landfill in Canada, have greatly contributed to our understanding of the physical and chemical processes that control the transport of chemicals in groundwater. For this project, we have used a similar approach i.e., intensively monitored sites with specially-designed monitoring networks to address the critical groundwater-to-indoor air vapor intrusion pathway. For this demonstration, vapor intrusion site investigations have been completed at a total of three buildings located at two demonstrations sites two single-family residences near Hill AFB and a small office building at Altus AFB. For each site, the investigation program consisted of an initial sample point installation and sampling event and one Hill AFB or two Altus AFB follow-up sampling events.
