The Influence of Transient Processes on Vapor Intrusion Processes

  title={The Influence of Transient Processes on Vapor Intrusion Processes},
  author={Y. Yao and K. G. Pennell and E. Suuberg},
A three dimensional vapor intrusion model was used to investigate the amount of time required to reach steady-state vapor intrusion rates. The effect of pressure fluctuations on vapor intrusion rates was also investigated. These results were obtained for a homogenous soil conceptual site model with groundwater located at 25 feet below ground surface. The time to achieve steady state ranged from approximately 6-12 months depending on geology. However, the time required for crack concentrations… Expand
