4 Benefits of Continuous Air Sampling for Vapor Intrusion

Typical grab sampling or integrated sampling methods used for indoor air monitoring to evaluate vapor intrusion risks may not tell you the whole story.  They represent only a static snapshot of conditions, or an average value of contaminant concentrations over a certain period of time. What’s the risk in that?  Sampling results may be misleading.  …
