Multiple source vapor intrusion investigations are challenging due to numerous potential sources of indoor air impacts. Use of limited measurements can lead to false conclusions regarding vapor intrusion. On-site analyses and other advanced methods can identify source of VOCs in quickly ( 1 day) and economically.
Indoor sources of volatile organic chemicals (VOCs) are ubiquitous, resulting in detectable concentrations in indoor air, often at concentrations above regulatory screening levels. At VOC contaminated sites with potential vapor intrusion concerns, the presence of indoor VOC sources significantly complicates the exposure pathway investigation. Because of these indoor sources, the detection of a site-related VOC in a potentially affected building at a concentration above the regulatory screening level does not ...
