WHO drinking water guidelines update
Guidelines for Drinking-Water Quality, Second Addendum to the 3rd Edition Volume 1 - Recommendations was released online by the World Health Organization (WHO) in December 2008. This addendum adds to and supersedes information in the third edition of the Guidelines. In response to feedback received, the second addendum includes more guidance on household water management, rainwater harvesting, vended water, temporary water supplies, and pesticides used for vector control in drinking-water sources. It also includes a series of new microbial and chemical fact sheets. Expanded fact sheets are included for key chemical risks such as arsenic, fluoride and nitrate/nitrite. You can find the main volume in HOORC's Library and the addendum online.
