Updated from the 1999 edition, this manual provides critical information regarding waterborne viral, bacterial and parasitic pathogens. Each pathogen is described along with its health effects, and water treatment techniques for destroying the pathogens. Also covered are cross-connection control, dead-end flushing, and hydrant flushing. This manual is intended for water operators, engineers, water quality personnel and students to learn how to monitor, sample and test waters for pathogens, optimize treatment plant performance and maintain high water quality standards.

Written by a team of international experts, this third edition designed to guide public health personnel or teams in any country that investigates reports of alleged waterborne illnesses. The manual is based on epidemiologic principles and investigative techniques that have been found effective in determining causal factors of disease incidence. The guidelines are presented in the sequence usually followed during investigations and are organized so that an investigator can easily find the information needed in any phase of an investigation. The book services as a guide to: • Develop a waterborne disease surveillance and emergency operations program • Handle illness alerts and water-related complaints that may be related to illness • Interview ill persons, those at risk, and controls • Develop a case definition • Transport water specimens and clinical specimens • Trace sources of contamination • Identify factors responsible for contamination, survival of pathogenic microorganisms or toxic substances, and/or propagation of pathogens • Collate and interpret collected data • Report information about the outbreak This edition has been extensively updated. A section has been added on water not intended for drinking as a source of illness. The chapter on “collection and analysis of data” has been significantly expanded to explain how data is collected and used to suggest possible vehicles, routes, and agents. The book is designed to improve the quality of investigation of outbreaks and disease surveillance. The International Association for Food Protection is a non-profit association of food safety professionals. Dedicated to the life-long educational needs of its Members, IAFP provides Members with an information network through its two scientific journals (Food Protection Trends and Journal of Food Protection), its educational Annual Meeting, international meetings and symposia along with international interaction between food safety professionals.

Updated from the 1996 edition, this manual provides water supply engineers and operators a single source for information about fiberglass pipe and fittings. New in this edition are the addition of metric equivalents; an expanded discussion of pipe mechanical properties with stress vs. strain curves; Buried Pipe Design chapter has expanded discussion of deflections caused by live loads and soil properties, a second method of determining pipe stiffness, and a new equation for pipe buckling; Guidelines for Underground Installation has additional information on soil backfill considerations and minimum trench width, new information on angularly deflected pipe joints, pressure testing, and a new section on trenching on slopes.

AWWA Manual of Water Supply Practice M57 provides all the information required by water treatment professionals to understand and mitigate problems caused by algae in source waters, such as tastes and odors, biofouling, and toxin production. With more than 450 pages and hundreds of photos and illustrations, the manual is a comprehensive reference for identifying and treating algae from drinking water sources.

This AWWA manual of practice provides water professionals with solutions to algae-related problems. Topics covered include identification of algal species, monitoring programs, and best management and treatment strategies.

Bacteriophages have received attention as biological control agents since their discovery and recently their value as tools has been further emphasized in many different fields of microbiology. Particularly, in drug design and development programs, phage and prophage genomics provide the field with new insights. Bacteriophages reveals information on the organisms ranging from their biology to their applications in agriculture and medicine. Contributors address a variety of topics capturing information on advancing technologies in the field. The book starts with the biology and classification of bacteriophages with subsequent chapters addressing phage infections in industrial processes and their use as therapeutic or biocontrol agents. Microbiologists, biotechnologists, agricultural, biomedical and sanitary engineers will find Bacteriophages invaluable as a solid resource and reference book.

Following the events of 9/11, the Administrator of the US Environmental Protection Agency created the Water Protection Task Force (WPTF), which identified water and wastewater systems as a major area of vulnerability to deliberate attack. The WPTF suggested that there are steps that can be taken to reduce these vulnerabilities and to make it as difficult as possible for potential saboteurs to succeed. The WPTF recommended that be scrutinized with renewed vigor to secure water and wastewater systems against these possible threats. It also recommended that water and wastewater systems have a response plan in place in the event an act of terrorism occurs. The WPTF identified water distribution networks as an area of special vulnerability and highlighted the need for rapid on-line detection methods that are accurate and have a wide detection range. As a result of these recommendations novel technologies from various fields of science and engineering are now addressing water security issues and water and wastewater utilities are looking for innovative solutions. Once such technologies are available, there will be a rapid implementation process that will present many business opportunities for the private sector. However, in addition to terrorist threats water and wastewater systems are inherently vulnerable to natural disasters such as earthquakes and floods. This volume will address the problems associated with both intended terrorist attacks and natural disasters affecting water or wastewater systems. The book is divided into parts based on the kinds of threats facing water and wastewater systems: (1) a direct attack on water and wastewater infrastructure storage reservoirs, and distribution and collection networks; (2) a cyber attack disabling the functionality of the water and wastewater systems or taking over control of key components which might result in system failures; and (3) a deliberate chemical or biological contaminant injection at one of the water distribution system’s nodes. It will examine unique plans, technological and managerial innovations for protecting such systems, and includes descriptions of projects that were implemented to respond to natural disasters. Case studies are presented that discuss existing projects and evaluate their performance, with an emphasis on providing guidelines and techniques that can be implemented by water and wastewater planners and managers to deal with natural and manmade disasters should they occur.
