Tools for Understanding Transients in Vapor Intrusion
Abstract
This study was motivated by recent reports from a number of vapor intrusion (VI)-impacted sites that the measured indoor concentrations of chemicals of concern could vary by orders of magnitude. The sites in question included two that were impacted by operations at military bases (Hill Air Force Base in Layton, UT and Naval Air Station North Island near San Diego, CA) and one studied by the US Environmental Protection Agency in Indianapolis, IN, where the impacts came from nearby former commercial establishments. The objective of this study was to apply numerical modeling to develop an improved understanding of the VI processes at these sites. The goal was also to demonstrate that such modeling tools offer insights that are difficult to develop without such formal analysis, establishing the value of mathematical modeling as a line of evidence in analyzing VI scenarios. A further objective of this work was to demonstrate that the tools needed for such numerical analysis are now at a level of development that no particular expertise in numerical analysis is required in order to make effective use of the tools.
