Book Description
"Perhaps no other advancement of public health has been as significant. Yet, few know the intriguing story of a simple idea-disinfecting public water systems with chlorine-that in just 100 years has saved more lives than any other single health development in human history. At the turn of the 20th century, most scientists and doctors called the addition of chloride of lime, a poisonous chemical, to public water supplies not only a preposterous idea but also an illegal act - until a courageous physician, Dr. John L. Leal, working with George W. Fuller, the era's greatest sanitary engineer, proved it could be done safely and effectively on a large scale. This is the first book to tell the incredible true story of the first use of chlorine to disinfect a city water supply, in Jersey City, New Jersey, in 1908. This important book also corrects misinformation long-held in the historical record about who was responsible for this momentous event, giving overdue recognition to the true hero of the story-an unflagging champion of public health, Dr. John L. Leal."--Back cover.

Book Description
Disinfection Byproducts in Drinking Water: Detection and Treatment presents cutting-edge research on how to understand the procedures, processes and considerations for detecting and treating disinfection by-products from drinking water, swimming pool water, and wastewater. The book begins with an overview of the different groups of Disinfection Byproducts (DBPs), such as: Trihalomethanes (THM), Halo acetic acids, and Haloacetonitrile (HAN). This coverage is quickly followed by a clear and rigorous exposition of the latest methods and technologies for the characterization, occurrence, formation, transformation and removal of DBPs in drinking water. Other chapters focus on ultraviolet-visible spectroscopy, electron spin resonance, and gas chromatography-mass spectrometry. Researchers will find a valuable resource to a breath of topics for DBP detection and treatment, including various recent techniques, such as microfiltration, nanofiltration membrane and nanotechnology. Explains the latest research in detection, treatment processes and remediation technologies Includes sampling, analytical and characterization methods and approaches Covers cutting-edge research, including membrane based technologies, nanotechnology treatment technologies and bioremediation treatment technologies Provides background information regarding contamination sources

Book Description
A working group of 23 experts from 13 countries met in Lyon to evaluate the evidence for carcinogenicity of arsenic (mostly naturally occurring) as a contaminant of drinking-water, and of the water-disinfectant chloramine. The working group also evaluated or re-evaluated four chlorination by-products found in drinking-water, namely chloral hydrate, di- and trichloroacetic acids, and 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as MX). High-level exposure to arsenic in drinking-water occurs in some regions such as China, Latin America, Bangladesh and West Bengal. The Working Group reviewed epidemiological studies of human cancer (mainly ecological studies in Taiwan and Chile, and several case-control and cohort studies) in relation to arsenic in drinking-water. Arsenic in drinking-water (primarily inorganic, as arsenate and to a lesser extent arsenite) was evaluated as carcinogenic to humans (Group 1) on the basis of sufficient evidence for an increased risk for cancer of the urinary bladder, lung and skin. Studies on inorganic arsenic in experimental animals provided limited evidence for its carcinogenicity, but sufficient evidence was found in experimental animals for the carcinogenicity of dimethylarsinic acid (an organic form of arsenic), which produced urinary bladder tumours in rats and lung tumours in mice after oral administration.

Book Description
New edition covers the latest practices, regulations, and alternative disinfectants Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment. This Fifth Edition, with its extensive updates and revisions, reflects the current state of the science as well as the latest practices. Balancing theory with practice, the Fifth Edition covers such important topics as: Advances in the use of UV and ozone as disinfectants Alternative disinfectants such as chlorine dioxide, iodine, and bromine-related products Advanced oxidation processes for drinking water and wastewater treatment New developments and information for the production and handling of chlorine Latest regulations governing the use of different disinfectants For each disinfectant, the book explains its chemistry, effectiveness, dosing, equipment, and system design requirements. Moreover, the advantages and disadvantages of each disinfectant are clearly set forth. References at the end of each chapter guide readers to the primary literature for further investigation. Authored and reviewed by leading experts in the field of water and wastewater treatment, this Fifth Edition remains an ideal reference for utilities, regulators, engineers, and plant operators who need current information on the disinfection of potable water, wastewater, industrial water, and swimming pools.

Book Description
Water is our natural heritage, our miracle of life. However, our increasingly technological society has become indifferent to water. Far from being pure, modern drinking water around the world contains many undesirable chemical and bacterial contaminants. The existing techniques employed for the disinfection of water are either energy-intensive or

Book Description
This text prepared by an international group of experts addresses the 'heterotrophic plate count' test which is widely used in drinking-water assessment: what it detects (and what it does not detect) its direct and indirect health significance and its use in the safety management of drinking water supplies. It includes the consensus statement from an expert review meeting and takes account of the presentations and posters at an international conference on the theme co-sponsored by WHO and NSF-International. It provides valuable information on the utility and the limitations of HPC data in the management and operation of piped water systems as well as other means of providing drinking water to the public. It is of particular value to piped public water suppliers and bottled water suppliers manufacturers and users of water treatment and transmission equipment and inline treatment devices water engineers sanitary and clinical microbiologists and national and local public health officials and regulators of drinking water quality. ...The book will be of great value to the piped public water suppliers bottled water suppliers manufacturers users of water treatment and transmission equipment and online treatment device makers water supply engineers sanitary engineers clinical and water microbiologists national and local public health officials and regulators of drinking-water quality. - Indian Journal of Medical Research

Book Description
Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
