The guidelines for drinking water quality

Guidelines for drinking water quality, 3rd edition cover

This third edition of WHO's Guidelines for Drinking-water Quality provides a state-of-the art perspective on issues of water quality and health and on effective approaches to water safety management.

The most important development in the 3rd edition was the introduction of a framework for drinking water safety [pdf 98 KB], which includes the development of water safety plans. The framework provides a comprehensive approach to water safety management.

The Guidelines are used by countries at all levels of development as a scientific basis for standard-setting and regulation and are used extensively by professionals and local decision makers.
