The assessment, remediation, and redevelopment of manufactured gas plant (MGP) sites pose a significant technical and financial challenge to successor property owners, including municipalities and other public entities undertaking brownfields revitalization, and to their consulting environmental engineers. Due to the toxicity of many coal tar constituents, sites contaminated as a result of gasworks operations pose a significant threat to public health. This book will discuss the history of the manufactured gas industry in Massachusetts (the largest in the US), as well as the toxicity of gasworks waste products, technical challenges in the cleanup process, and the process for site cleanups.

Winner of the 2013 Claire P. Holdredge Awardee for Remediation of Former Manufactured Gas Plants and Other Coal-Tar Sites. This award, first established in 1962 by the Association of Environmental and Engineering Geologists, is named in honor of Claire P. Holdredge, a founding member and the first President of the Association. The award is presented for a publication by an AEG Member(s) within the 5 previous years that is adjudged to be an outstanding contribution to the Engineering Geology profession. Remediation of Former Manufactured Gas Plants and Other Coal-Tar Sites is geared toward environmental professionals who want to design and implement gasworks remediation strategies that offer the greatest chance to successfully protect the public. Exploring the bases for selecting remedial alternatives to adequately address today’s environmental wounds, this compendium of essential knowledge combines historic and modern scientific data and technology with common sense and empirical lore passed down from past generations of gas professionals, a group that is now all but extinct. Most of the general population does not have a sufficient understanding of remediation needs. Unfortunately, there seems to be a similar lack of knowledge among some environmental professionals whose job it is to protect the public from the health threats associated with coal tar. Pitfalls in remediation are common and represent a significant risk to the public, especially when processes are based on inaccurate assumptions. This book sifts through the existing scholarship from around the developed world to present the necessary evaluation factors used in effective remediation. Almost encyclopedic in scope, it offers 265 separate tables with checklists, hard data facts, and associations to help readers define site-specific gas plant conditions. It also includes a plethora of photographs and historic drawings, as well as an extensive glossary that is indispensible for understanding potential and actual gas plant contamination. Useful for engineers, scientists, regulators, public officials, historians, and journalists among others, this book is intended for those who conduct remediation, as well as those involved in review and oversight. Its goal is to bring users closer to safely reclaiming land and reviving old coal gasworks sites in ways that ultimately will be sustainable for the public interest.

Winner of the 2017 CBHL Literature Award of Excellence in Landscape Design and Architecture Phyto presents the concepts of phytoremediation and phytotechnology in one comprehensive guide, illustrating when plants can be considered for the uptake, removal or mitigation of on-site pollutants. Current scientific case studies are covered, highlighting the advantages and limitations of plant-based cleanup. Typical contaminant groups found in the built environment are explained, and plant lists for mitigation of specific contaminants are included where applicable. This is the first book to address the benefits of phytotechnologies from a design point of view, taking complex scientific terms and translating the research into an easy-to-understand reference book for those involved in creating planting solutions. Typically, phytotechnology planting techniques are currently employed post-site contamination to help clean up already contaminated soil by taking advantage of the positive effects that plants can have upon harmful toxins and chemicals. This book presents a new concept to create projective planting designs with preventative phytotechnology abilities, ‘phytobuffering’ where future pollution may be expected for particular site programs. Filled with tables, photographs and detailed drawings, Kennen and Kirkwood's text guides the reader through the process of selecting plants for their aesthetic and environmental qualities, combined with their contaminant-removal benefits.

In the past decade, officials responsible for clean-up of contaminated groundwater have increasingly turned to natural attenuation-essentially allowing naturally occurring processes to reduce the toxic potential of contaminants-versus engineered solutions. This saves both money and headaches. To the people in surrounding communities, though, it can appear that clean-up officials are simply walking away from contaminated sites. When is natural attenuation the appropriate approach to a clean-up? This book presents the consensus of a diverse committee, informed by the views of researchers, regulators, and community activists. The committee reviews the likely effectiveness of natural attenuation with different classes of contaminants-and describes how to evaluate the "footprints" of natural attenuation at a site to determine whether natural processes will provide adequate clean-up. Included are recommendations for regulatory change. The committee emphasizes the importance of the public's belief and attitudes toward remediation and provides guidance on involving community stakeholders throughout the clean-up process. The book explores how contamination occurs, explaining concepts and terms, and includes case studies from the Hanford nuclear site, military bases, as well as other sites. It provides historical background and important data on clean-up processes and goes on to offer critical reviews of 14 published protocols for evaluating natural attenuation.

This book provides an account of the major environmental contaminations present today, and offers detailed insights into their potential remediation through bio-based solutions. Bringing together the work of various international experts in this field, it contains comprehensive reviews on the mechanisms of bioremediation. Moreover, the book discusses the strategies by which bacteria and plants help in the decontamination of environmental pollutants. As such, it represents a valuable resource for a wide audience, including environmental scientists, biochemists, soil scientists, botanists, agronomists and molecular biologists.

This two-volume work is an effort to provide a common platform to environmental engineers, microbiologists, chemical scientists, plant physiologists and molecular biologists working with a common aim of sustainable solutions to varied environmental contamination issues. Chapters explore biological and non-biological strategies to minimize environmental pollution. Highly readable entries attempt to close the knowledge gap between plant - microbial associations and environmental remediation. Volume 1 focuses on important concepts such as biological remediation strategies to enhance soil quality at contaminated sites; synergistic influences of tolerant plants and rhizospheric microbial strains on the remediation of pesticide contaminated soil, and the role of plant types such as hyperaccumulator plants in the cleanup of polluted soils. Readers will discover mechanisms and underlying natural inherent traits of various plants and microbes for tolerating, excluding, remediating, accumulating, or metabolizing a variety of pollutants.
