Heterotrophic Plate Counts and Drinking-water Safety provides a critical assessment of the role of the Heterotrophic Plate Count (HPC) measurement in drinking water quality management. It was developed from an Expert workshop of 32 scientists convened by the World Health Organization and the WHO/NSF International Collaborating Centre for Drinking Water Safety and Treatment in Geneva, Switzerland. Heterotrophs are organisms, including bacteria, yeasts and moulds, that require an external source of organic carbon for growth. The HPC test (or Standard Plate Count), applied in many variants, is the internationally accepted test for measuring the hetrotrophic microorganism population in drinking water, and also other media. It measures only a fraction of the microorganisms actually present and does not distinguish between pathogens and non-pathogens. High levels of microbial growth can affect the taste and odor of drinking water and may indicate the presence of nutrients and biofilms which could harbor pathogens, as well as the possibility that some event has interfered with the normal production of the drinking water. HPC counts also routinely increase in water that has been treated by an in-line device such as a carbon filter or softener, in water-dispensing devices and in bottled waters and indeed in all water that has suitable nutrients, does not have a residual disinfectant, and is kept under sufficient conditions. There is debate among health professionals as to the need, utility or quantitative basis for health-based standards or guidelines relating to HPC-measured regrowth in drinking water. The issues that were addressed in this work include: the relationship between HPC in drinking water (including that derived from in-line treatment systems, dispensers and bottled water) and health risks for the general public the role of HPC as an indirect indicator or index for pathogens of concern in drinking water the role of HPC in assessing the efficacy and proper functioning of water treatment and supply processes the relationship between HPC and the aesthetic acceptability of drinking water. Heterotrophic Plate Counts and Drinking-water Safety 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.

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.

FIND OUT THE ANSWERS TO THESE QUESTIONS AND MORE: How can a jellyfish, which is almost entirely water and has neither a heart nor a brain, be a living and consciously responsive being? What kind of water is best for our well-being? Why cold water swimming is so good for us? Can water be influenced by thoughts and emotions? Does water remember? What do we really know about water? Could solving the mystery of water also help us understand ourselves? In an unprecedented way, Johanna Blomqvist dives into the mystery of water in her book, approaching water through science, physics, and the latest research, as well as from an experiential perspective. What follows is not only an interesting journey into the history and essence of water but also a highly personal dive into the various ways water influences us during our lifetimes and even through generations. Water is a simple molecule, yet we do not fully understand it. It has many strange and exceptional properties that have yet to be explained. Even the structure of water has yielded surprising results in recent studies. It appears there might be two types of water. The structure of water can begin to mimic the molecules with which it has been in contact, bringing about their effects. Even emotions seem to have a connection to water. Water increasingly appears as a state of being between the material and immaterial worlds. Water is a mystery that we need to solve to understand ourselves — after all, we are over 70% water. Water symbolizes vitality, renewal, creativity, and change. Water is fundamental and sacred. Water is the beginning and the end — from it we are born, and often it has also been the fate of our civilizations, in the form of a flood or other upheaval. "I feel that water is now my teacher, and my task is to discover who I really am and what my deepest essence is. Looking deeply is also a form of surrender. When one dares to surrender and let go, a path unfolds, becoming increasingly clear." The Mystery of Water makes you see water in a new way. You will find a new connection to water — to our deepest essence. Water may contain fundamental answers to our life, existence, and also our future.
