Book Description
Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Book Description
This research studied the use of multi-element sensors based on electrochemical techniques for optimizing information related to corrosion control in water distribution systems. Such on-line sensor methods could provide an affordable and reliable tool for daily monitoring and mitigate some of the costs associated with following the mandates of the EPA's corrosion control for potable water.

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.
