This volume contains 13 chapters that detail how to plan, design, model, and apply permeable reactive barrier (PRB) technology for the remediation of groundwater from contaminated sites by allowing it to pass through a buried porous barrier that captures the contaminants or breaks them down. Scientists from the US Environmental Protection Agency and universities and companies in Germany, Australia, and Hungary address developments in PRBs; choosing design and construction technologies for them; predictive modeling to assist in design; and applications, including the impact of trace elements and impurities in technical zero-valent iron brands on reductive dechlorination of chlorinated ethenes in groundwater, the assessment of a PRB for the treatment of hexavalent chromium and trichloroethylene, the pretreatment of nitrate and remediation of trichloroethene, the treatment of heavy metals, arsenic, and acidity, radionuclides, reactive gas barrier and zone technologies, and the remediation of polycyclic aromatic hydrocarbons, NSO-heterocycles, and related aromatic compounds. The book also has a case study of a site in Australia and discusses the use of PRBs in Europe. Annotation ©2015 Ringgold, Inc., Portland, OR (protoview.com)
Remediation of ground water is complex and often challenging. The passive remediation technology, currently in vogue, is based on permeable reactive barriers (PRB) that allow water to pass through while the fence/barrier made of reactive materials remediates the contaminants. Although PRB has been in operation for over a decade there are limited published books available. This book covers in one single volume all the information needed to plan, design/model and apply a successful, cost-effective and sustainable PRB technology.

Professor Ravi Naidu is the chief executive and managing director of the Cooperative Research Centre for Contamination Assessment and Remediation of the Environment. He has researched environmental contaminants, toxicology, bioavailability, and remediation for over 20 years. Ravi has co-authored over 500 technical publications and co-edited 10 books in the field of soil and environmental sciences including field remediation of contaminated sites. His current research focuses on the remediation of contaminated soil, water and potential impacts of contaminants to environmental and human health.
Dr. Volker Birke has around 25 years of experience in organic and environmental chemistry, particularly in green chemistry, the destruction of hazardous wastes and toxic compounds in the environment. He has experience in remediation of contaminated sites, hazardous waste management, and especially ground water remediation, with 12 years as coordinator of the large-scale German R&D program "RUBIN" for the application of permeable reactive barriers (PRBs) to ground water pollution, 25 years in the development and application of innovative ex situ and in situ remediation technologies to persistent organic pollutants (POPs), particularly mechanochemical dehalogenation (MCD) regarding ex situ treatment, as well as innovative ground water remediation technologies such as PRBs or nano and micro scale reactive particles for in situ treatment of polluted ground water. Another focus covers environmental analytics, especially regarding POPs such as polychlorinated biphenyls (PCBs) or dibenzodioxins (PCDD).
He has been senior scientist, project leader, and senior lecturer in environmental chemistry and engineering at the Faculty of Civil and Environmental Engineering at the Ostfalia University of Applied Sciences, Campus Suderburg, Germany, since 2000. Since 2009, he has been commissioned to administer the professorship of chemistry at the faculty. He teaches the management of contaminated sites, remediation technologies, chemistry, physics, and mathematics for engineers and environmental scientists as well as occupational health and safety, with a focus on special applications and requirements for working in areas contaminated by hazardous compounds and at polluted sites.
Dr. Birke has been involved in the management of about 50 remedial investigations, remedial designs and clean-up of polluted sites in Germany as well as abroad (Europe, the United States, India, Australia). He received a PhD in organic chemistry from the University of Hanover. Dr. Birke has published about 50 papers focusing on innovative ex situ and in situ remediation technologies such as mechanochemical dehalogenation and PRBs and is the main author of one book on remediation of contaminated sites using PRBs in Germany.
