A comparison of disinfection by-product (DBP) results for 12 surface source waters on Vancouver Island, British Columbia determined that there was a distinct spatial difference in DBP production based on biogeoclimatic ecoregions. The main factors affecting the DBP production between ecoregions was source water quality, water body type (stream versus lake) and treatment strategy. Typically water bodies within an ecoregion exhibit similar water quality and produce similar DBPs. Differences in DBPs between water body types were attributed to the source of natural organic matter (NOM), allochthonous or autochthonous origin, and seasonal variability. Additional source water quality parameters such as pH, chlorophyll a, total phosphorus, water temperature and bromide concentrations support the spatial differences observed in DBP production between ecoregions. These results suggest that source water quality and water body type could be used as a preliminary tool to predict the amount of DBPs a community within a specific ecoregion may be exposed to. A review of a long-term data set determined that changes in treatment strategy significantly affected the DBPs produced. The most distinct changes in DBP production were associated with booster station treatment processes in terms of annual versus seasonal re-chlorination and the decommissioning of a booster station. Sooke reservoir water quality, following an inundation project, changed significantly with respect to water temperature and NOM. The increase in TOC levels did not result in any changes to DBP production, however cooler water temperatures reduced the potential for losses of chlorine residual and for the re-growth of bacteria. The results of this research suggest that the management and protection of drinking water sources, along with treatment strategies, is the most promising way to ensure minimal risk to human health.

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.

The EPA has established regulations which classify four types of disinfection byproducts - TTHMs, haloacetic acids, bromate, and chlorite - and requires public water systems limit these byproducts to specific levels. Most of the information required to comply with these standards is either scattered throughout the literature or derived from confere

A state-of-the-science review of the toxicological effects of disinfectants and their by-products, this report considers the implications of these effects upon anticipated regulations. It considers both the residual concentrations of disinfectants that remain when water is consumed and the formation of disinfection by- products, focusing on factors most likely to affect the development of maximum contaminant levels and the consequential effect on the use of disinfectants.

One of the conclusions of the study is that the chemistry of the source water is an important variable in determining not only the concentration but also the types of by-products that are formed when drinking water utilities disinfect their systems. The report covers risk assessment, the chemistry of disinfection by-product formation, the occurrence of by-products in drinking water, epidemiology, toxicological profiles of disinfectants and by-products, practical considerations for individual water systems, communicating with the public, and directions for future research. It is double spaced and not indexed. c. Book News Inc.
