Select "API Soil and Groundwater Research BulletinsOther
bulletins dealing with vapor transport are #16 and #15.Technical bulletin #15 describes 4 basic soil gas concentration
profiles in the vadosezone and (may) describe how best to fit a
model to them.This was the beginning of the work that led
to the O2-limited vapor model.The "Dominant Layer
Model" as used in RISC is presented in API Publication Number
4674 which costs $55.
