Project 3: sub-slab depressurization systems

An example of the predicted influence of sub-slab depressurization systems on the VOC contaminant concentration beneath a house (red indicates high concentrations, blue, low concentrations; the right panel shows the “unprotected” house, and the left the same house with a depressurization system activated). This is an example of how three dimensional engineering modeling of a vapor intrusion situation can guide the design of measures aimed at protecting residents.
