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.

Factors Affecting Disinfection By Products From Surface Source Waters On Vancouver Island written by Deborah Epps and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2009 with Water categories.
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.

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

There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater. Desalination assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities.
