ESTCP Project ER-201125, 50 pp, 2016

This document presents a tool for estimating vapor intrusion into buildings from unsaturated (vadose) zone contaminant sources. The tool builds on and is related to guidance for evaluation of soil vapor extraction performance relative to the impact of a vadose zone source on groundwater concentrations. This user guide is available with several tools for estimating vapor intrusion at the bottom of the project web page: https://www.estcp.com/Program-Areas/Environmental-Restoration/Contaminated-Groundwater/Emerging-Issues/ER-201125.
