Book Description
The research reported on here sought to characterize natural organic matter (NOM) in dilute solutions and to isolate it without altering its properties, so that the effect of NOM in drinking water may be considered. Several NOM isolation methods were evaluated, including evaporation, reverse osmosis, nanofiltration, and adsorption. The effects of such isolation procedures on NOM's chemical composition and reactivity were considered. Based on these studies, the report presents conclusions regarding the feasibility and adequacy of in situ and ex situ techniques.

Book Description
As part of the effort to balance water treatment processes between allowing pathogenic infection by doing too little, and raising the risk of cancer with by-products of the treatment, 20 papers from a symposium in Chicago, August 1995, present information on the chemical identity of natural organic matter and its interactions with the inorganic precursor bromide ion. They review the history of natural organic matter in water treatment and the impact of regulations, then plunge into reports on an economical experimental approach to developing predictive models for by-products of disinfection, a comparison of analytical techniques for determining cyanogen chloride in chloraminated drinking water, the effect of ozonation and biotreatment on molecular size and hydrophilic fractions of natural organic matter, removing bromate ion by electric-arc discharge and high-energy electron beam processes, and other topics.

Book Description
Disinfection By-Products and Human Health is based on contributions from speakers who participated in May 2011 workshops on Disinfection By-Products (DBPs) and Human Health at Ozwater 11 in Adelaide, Australia or at an AWA sponsored workshop at the Curtin Water Quality Research Centre, Perth, Australia. The contributions are prepared to facilitate communication with practitioners, rather than researchers, making use of overview illustrations rather than dense text or data tables. Each chapter concludes with up to 5 key findings that are take-home messages for practitioners. Disinfection By-Products and Human Health is aimed specifically at drinking water professionals (engineers, chemists and public health professionals) working on the front lines of drinking water issues where they must encounter actual day-to-day issues of risk management concerning DBPs in relation to all the other regulatory and water quality issues they must manage. Although a topic this complex is certainly not amenable to simplistic explanations, this book aims to provide drinking water professionals with a pragmatic assessment of the current evidence and emerging issues concerning DBPs and public health. Disinfection By-Products and Human Health is an essential, practical and accessible guide for drinking water professionals, engineers, chemists and public health professionals. Editors: Steve E. Hrudey, Professor Emeritus, Analytical & Environmental Toxicology, University of Alberta, Canada, Jeffrey W.A. Charrois, Director and Associate Professor, Curtin Water Quality Research Centre, Curtin University of Technology, Australia, Steve Hrudey is professor emeritus in analytical and environmental toxicology in the University of Alberta's Faculty of Medicine & Dentistry. He spent 13 years as a cabinet-appointed member of the Alberta Environmental Appeals Board, the last four as chair, and was the first non-lawyer to hold this position. During this period, he served on 36 public hearing panels, 19 as chair of the panel. In addition he has testified before senate committees in Canada and the Legislative Council in Western Australia. Hrudey has served on a number of high-profile expert panels, including the Research Advisory Panel to the Walkerton Inquiry (2000-2002), the Expert Panel on Safe Drinking Water for First Nations (2006), the Technical Advisory Committee to the B.C. Minister of Health on turbidity and microbial risk in drinking water (2007-2008, as chair), the Expert Advisory Panel on Water Quality for Washington, D.C., to the U.S. Army Corps of Engineers (2009-2011) and chair of the Royal Society of Canada Expert Panel on Environmental and Health Impacts of Canada's Oil Sands Industry (2009-2010). He has also co-authored or edited nine books, including the widely acclaimed book inspired by the Walkerton tragedy: Safe Drinking Water - Lessons from Recent Outbreaks in Affluent Nations (IWA Publishing, 2004). He has written 26 book chapters, 19 expert panel reports, 163 refereed journal articles, 15 science discussions, six media op-eds and 73 conference proceeding papers.

Book Description
Drinking water quality has been a matter of concern for several decades. Disinfection of drinking water improves its microbiological quality and prevents disease outbreaks. However, continuously increasing scientific research concerns the presence of organic and inorganic contaminants in water. Many of these compounds, named haloforms, originate from the procedure of disinfection, being formed during reactions of disinfectants with natural organic matter present in water. Haloforms may possess carcinogenic or mutagenic properties; therefore minimization of their concentrations in drinking water is a critical issue. Regulatory measures are becoming more and more stringent, as new health effects become known and optimized high-sensitivity analytical methodologies are being developed. Up-to-date research findings concerning all these aspects have been collected, critically reviewed, summarized, and are presented and discussed in the present book.

Book Description
Drinking water disinfection has markedly reduced diseases causes by waterborne pathogenic microorganisms. However, an unintended consequence of disinfection and/or oxidation processes is the generation of disinfection byproducts (DBPs) which are formed from the reactions of disinfectants/oxidants with water matrix components. This volume of the Comprehensive Analytical Chemistry Handbook presents recent advances about the formation, identification, and quantification of inorganic and organic DBPs during oxidative processes. The book begins with a first chapter reviewing the most recent non-targeted screening approaches and workflows to characterize DBPs using low-, high-, and ultra-high-resolution mass spectrometry. The second chapter discusses the analysis of inorganic chloramines in waters using on-site and/or in-lab analytical methods. The third chapter provides an overview of the current knowledge about the mechanisms of chlorine dioxide reactions and byproducts formation. The fourth chapter presents some fundamental and practical aspects about ozonation processes in water treatment and provides an overview about ozone reaction mechanisms and byproducts formation. The fifth chapter focuses on the reactivity of halide ions, particularly bromide and iodide, with common oxidants and the role they play in determining the speciation of DBPs in treated waters. The chapter also presents strategies to mitigate the formation of DBPs during oxidation processes. Finally, the last chapter tackles the topic of DBPs formation during potable water reuse. It discusses the formation of DBPs of major concern in both memebrane-based and non-membrane-based potable water reuse treatment schemes.Researchers, water treatment specialists, and regulators will find in this book a valuable and compact resource on several key topics regarding the formation, identification, quantification, and mitigation of DBPs. - Identification and quantification of known and unknown DBPs - Formation of DBPs during different disinfection/oxidation processes - DBPs of concern in new technologies and/or new applications of existing technologies in water treatment
