This book introduces key concepts in modeling and risk assessments of
vapor intrusion, a process by which the subsurface volatile contaminants
migrate into the building of concern. Soil vapor intrusion is the major
exposure pathway for building occupants to chemicals from the
subsurface, and its risk assessments determine the criteria of volatile
contaminants in soil/groundwater in brownfield redevelopment. The
chapters feature the recent advances in vapor intrusion studies and
practices, including analytical and numerical modeling of vapor
intrusion, statistical findings of United States Environmental
Protection Agency's Vapor Intrusion Database and Petroleum Vapor
Intrusion Databases, the challenges of preferential pathways, and the
application of building pressure cycling methods, and field practices of
vapor intrusion risk assessments at developed contaminated sites and in
brownfield redevelopment. This volume also summarizes the advantages and
limits of current applications in vapor intrusion risk assessment,
laying the groundwork for future research of better understanding in
risk characterization of soil vapor intrusion using models.
Written by experts in this field, Vapor Intrusion Simulations and Risk
Assessments will serve as an invaluable reference for researchers,
regulators, and practitioners, who are interested in perceiving the
basic knowledge and current advances in risk assessments of soil vapor
intrusion.
