The purpose of this Engineering Issue Paper (EIP) is to summarize the “state of the science” regarding the use of passive air samplers in air quality investigations, focusing on investigations assessing subsurface vapor intrusion (VI) to indoor air.
This Paper covers the basics of passive sampler design, compares passive samplers to conventional methods of air sampling, and discusses considerations when implementing a passive sampling program. The Paper also discusses field sampling and sample analysis considerations to ensure data quality is adequate and interpretations based on the passive sample data are supportable. The reader is expected to have a basic technical background on the VI exposure pathway and how to use and interpret indoor air sampling data in the context of a VI investigation.
