of groundwater is the primary strategy for remediation. Other less passive
approaches include
• Pump and treat
• Bioventing
• Chemical oxidation (in situ)
• Permeable reactive barrier (more recent)
Pump and treat was one of the first techniques to be trialed in the United
States. This involves pumping groundwater through an ex situ reactor and
the cleansed water then reinjected back into the aquifer. Although pump and
treat has often been unsuccessful and is prohibitively expensive, it is still
widely used by large companies seeking to comply with the demands of regulators. Both bioventing and chemical oxidation techniques are also widely
used and have proven similarly expensive and unattractive to owners of
contaminated sites. For an overview of remediation techniques, readers are
referred to a recent paper by Naidu (2013). Given the high cost of pump and
treat technology, a host of other technologies for hydrocarbon remediation
is also being tested in the field. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a
buried porous barrier that either captures the contaminants or breaks them
down. This approach is gaining popularity in the United States, Europe, and
Australia. This book covers
• Two decades of experience in PRB applications
• Design criteria
• Predictive modeling to assist the design of PRBs
• Application to contaminants beyond petroleum hydrocarbons,
including inorganics and radionuclides
• New areas of research
The book is intended for individuals responsible for the management of site
contamination programs, regulators, remediators, and postgraduate students.
