Drinking Water Criteria

Quality criteria for raw water generally follow drinking-water criteria and even strive to attain them, particularly when raw water is abstracted directly to drinking-water treatment works without prior storage. Drinking-water criteria define a quality of water that can be safely consumed by humans throughout their lifetime. Such criteria have been developed by international organisations and include the WHO Guidelines for Drinking water Quality (WHO, 1984, 1993) and the EU Council Directive of 15 July 1980 Relating to the Quality of Water Intended for Human Consumption (80/778/EEC), which covers some 60 quality variables. These guidelines and directives are used by countries, as appropriate, in establishing enforceable national drinking-water quality standards.
