DOWNLOAD EBOOK →This is the third edition of the WHO's guidelines which are used by countries worldwide to set standards for the regulation of drinking water quality and effective approaches to water safety management. This revised edition has been updated to take account of recent developments in risk assessment and management. Topics discussed include: a framework for drinking water safety and discussion of the roles and responsibilities of different stakeholders, such as national regulators, water suppliers and independent surveillance agencies; guidance on microbial safety of drinking water through safety plans; new scientific information on chemicals, waterborne pathogens and individual chemical hazards of actual or potential concern. It also considers the application of the guidelines in specific circumstances, such as in emergencies and disasters, and to specific applications, such as bottled water. It also contains information on over 130 documents which substantiate or explain the content of the Guidelines, and on good practice guidance in achieving drinking-water safety.

These criteria are to accurately reflect the latest scientific knowledge (a) on the kind and extent of all identifiable effects on health and welfare including, but not limited to, plankton, fish shellfish, wildlife, plant life, shorelines, beaches, aesthetics, and recreation which may be expected from the presence of pollutants in any body of water including ground water; (b) on the concentration and dispersal of pollutants, or their byproducts, through biological, physical, and chemical processes; and (c) on the effects of pollutants on biological community diversity, productivity, and stability, including information on the factors affecting rates of eutrophication and organic and inorganic sedimentation for varying types of receiving waters. In a continuing effort to provide those who use EPA's water quality and human health criteria with up-to-date criteria values and associated information, the document was assembled. The document includes summaries of all the contaminants for which EPA has developed criteria recommendations.
