2002 Edition Of The Drinking Water Standards And Health Advisories

This volume describes the methods used in the surveillance of drinking water quality in the light of the special problems of small-community supplies, particularly in developing countries, and outlines the strategies necessary to ensure that surveillance is effective.

This publication contains the first addendum to Volume One of the 3rd edition (2004, ISBN 9241546387) 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, including approaches to ensuring microbial safety. It gives details of all changes to the Guidelines since 2004, including the addition of three new chemical fact sheets and revisions to several others, updated guideline summary tables, new information to address local actions in response to chemical water quality problems and emergencies, an expanded discussion of chemicals used in water treatment and chemicals arising from materials in contact with water, and a complete list of minor revisions or amendments.
