What is it about?
The migration of Vapor phase contaminants from subsurface to the ground or a building is a complex process. This article provides a simple method to estimate how long it will take for the vapor contaminant to reach a constant state of maximum concentration.

Why is it important?
By knowing the time for subsurface vapor phase contaminants to reach the ground surface or a building basement, one can develop a better sampling plan for monitoring and/or mitigating the vapur intrusion issues.
