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.

Cuprins

Chapter 1 Introduction of the concepts and history of vapor intrusion (VI)
Author: Yijun Yao
This chapter gives the readers the basic idea about VI. We are planning to introduce the concepts, history, and framework of risk assessments in VI investigations.
 
Chapter 2 Statistical analysis of USEPA’s VI database
Author: Yijun Yao
This chapter introduces the development of USEPA’s VI database, and the use of it in determining generic attenuation factors. The limits of the database and improvements to generate more realist generic attenuation factors are also discussed.
 
Chapter 3 Statistical analysis of USEPA’s PVI database
Author: Yijun Yao
This chapter introduces the development of USEPA’s PVI database, and the use of it in obtaining vertical screening distances for PVI. Numerical simulations are also involved to justify the developed screening distances for NAPL and dissolved-phase sources of traditional petroleum products.
 
Chapter 4 Screening models of vapor intrusion (VI)
Author: Iason Verginelli
This chapter summarizes existing analytical models of vapor intrusion, and discusses the limits of current screening tools commonly used in this field, and the future research to improve them.
 
Chapter 5 Numerical models of vapor intrusion
Author: Iason Verginelli
This chapter summarizes the current numerical models of vapour intrusion and their use in simulating multiple dimensional scenarios of vapor intrusion and petroleum vapour intrusion.
  Chapter 6 Alternative VI pathways
Author: Yijun Yao
This chapter introduces alternative VI pathways, that connecting subsurface vapour sources with subfoundation zone or indoor air, and discusses the scenarios in which it may play an important role in determining indoor air concentration.
 
Chapter 7 PVI involving High-Ethanol Blend
Author: Jie, Ma
This chapter discusses the possible hazards caused by vapor intrusion form a subsurface source involving high-ethanol blend, a kind of biofuel currently used. The investigations are involving a pilot-scale experiment, analytical calculations, and numerical modelling.
 
Chapter 8 Field practice to assess VI risks at developed sites
Author: Eric Suuberg
This chapter introduces the characterizations of soil vapour intrusion at a developed site, based on a technique of multiple lines of evidences, which includes groundwater sampling, subslab soil gas samples, exterior soil gas samples and indoor air samples, as well as screening model calculations.
  Chapter 9 Field practice to assess VI risks in brownfield redevelopment
Author: Tao Long
The chapter introduces the practical methods to characterize soil vapor intrusion in a brownfield redevelopment case, with a purpose to determine the remediation criteria of soil/groundwater pollution. This chapter also includes an example where chlorinated solvents are involved due to the production of pesticides.


Notă biografică
