Introduction 3

air flow rate, extracted COC concentrations, effect of temperature on vapor
flow, cleanup time, and sizing of vacuum pumps.
Chapter 6: Groundwater Remediation. This chapter starts with design cal-
culations for capture zone and optimal well spacing. The rest of the chap-
ter focuses on design calculations for commonly used in situ and ex situ
groundwater remediation technologies, including activated carbon adsorp-
tion, air stripping, in situ and ex situ bioremediation, air sparging, bio-
sparging, chemical precipitation, in situ chemical oxidation, and advanced
oxidation processes.
Chapter 7: VOC-Laden Air Treatment. Remediation of impacted soil and
groundwater often results in transferring organic COCs into the air phase.
Development and implementation of an air emission control strategy are an
integral part of the overall remediation program. This chapter illustrates
design calculations for commonly used off-gas treatment technologies,
including activated carbon adsorption, direct incineration, catalytic incin-
eration, internal combustion (IC) engines, and biofiltration.

1.3 How to Use This Book
This book is constructed to provide a comprehensive coverage of commonly
used soil and groundwater remediation technologies. It is written in a cook-
book style and user-friendly format. Both SI and US customary units are used
throughout the book, and unit conversions are frequently given. Examples
are given following the design equations. Some of the examples are provided
to illustrate important design concepts. One of the best ways to use the book
is to glance through the entire book first, by reading the text and skimming
the problem statement and discussion, and revisit the specific topics in detail
later when related design calculations are to be made.
