Book Description
Small communities violate federal requirements for safe drinking water as much as three times more often than cities. Yet these communities often cannot afford to improve their water service. Safe Water From Every Tap reviews the risks of violating drinking water standards and discusses options for improving water service in small communities. Included are detailed reviews of a wide range of technologies appropriate for treating drinking water in small communities. The book also presents a variety of institutional options for improving the management efficiency and financial stability of water systems.

Book Description
Manual of Small Public Water Supply Systems presents current concepts and practices affecting water treatment, financing, management, community involvement in water supply, institutional support, and development of human resources for improved operations and management of water supplies. Information on ground water, surface water, and SDWA requirements is also provided. In short, everything you need to run your small water treatment facility can be found in this book. Material is presented in a thorough, easy-to-read format and a complete bibiliography is included. Fully illustrated, Manual of Small Public Water Supply Systems will soon be dog-eared with use.

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.

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
In 2004, the WHO Guidelines for Drinking Water Quality recommended that water suppliers develop and implement "Water Safety Plans" (WSPs) in order to systematically assess and manage risks. Since this time, governments and regulators, water suppliers and practitioners have increasingly embraced this approach, but they have also requested further guidance. This much-anticipated workbook answers this call by describing how to develop and implement a WSP in clear and practical terms. Stepwise advice is provided through 11 learning modules, each representing a key step in the WSP development and implementation process: 1. Assemble the WSP team; 2. Describe the water supply system; 3. Identify hazards and hazardous events and assess the risks; 4. Determine and validate control measures, reassess and prioritise the risks; 5. Develop, implement and maintain an improvement/upgrade plan; 6. Define monitoring of the control measures; 7. Verify the effectiveness of the WSP; 8. Prepare management procedures; 9. Develop supporting programmes; 10. Plan and carry out periodic review of the WSP; 11. Revise the WSP following an incident ; Every Module is divided into three sections: 'Overview', 'Examples and Tools', and 'Case studies'. The overview section provides a brief introduction to the Module, including why it is important and how it fits into the overall WSP development and implementation process. It outlines key activities that should be carried out, lists typical challenges that may be encountered, and summarizes the essential outputs to be produced. The examples and tools section provides resources which could be adapted to support the development and implementation of WSPs. These resources include example tables and checklists, template forms, diagrams, or practical tips to help a WSP team address specific challenges. These are often example outputs and methodologies adapted from recent WSP experiences. Each Module concludes with case studies so the reader can benefit from lessons-learned from real-life experiences. They are intended to make WSP concepts more concrete and to help readers anticipate issues and challenges that may arise. The descriptions were drawn from WSP initiatives in Australia, the Latin American and the Caribbean region (LAC), and the United Kingdom.
