The World Health Organisation (WHO) launched an updated edition of drinking water guidelines on July 4 to push water suppliers to systematically manage the potential risk of contaminants entering water, from the catchment to the consumer. Launched at the Singapore International Water Week (http://www.who.int/en/ and http://www.siww.com.sg/), they can help governments strengthen their management of drinking water quality by adopting water safety planning. The new edition is based on the latest scientific evidence and includes hundreds of risk assessments on specific waterborne hazards.
