Soil Vapor Intrusion is rapidly becoming another area of concern in environmental investigations. Vapor Intrusion is the process by which subsurface volatile contaminants find a pathway into an overlying building. Such a pathway could cause potential adverse health effects to persons in the affected building. To assess whether or not a site is susceptible to vapor intrusion, a qualified consulting firm may perform an initial site assessment which may include testing of indoor air. Such a test would require achieving very low detection limits so that risk assessment calculations can be performed. Should remediation actions be required, that same need for ultra low detection limits and an experienced laboratory would be essential.

AirTECHNOLOGY has been in the fore-front of vapor intrusion projects, participating in ground-breaking vapor intrusion projects and developing a GCMS method that achieves method detection limits in the sub-parts-per-trillion levels.

Table 1 provides a list of the analytes that can be determined using the ultra low-level method.  Additional analytes can be included.
