[Public Review] World Health Organization revisions to the guidelines for drinking-water quality

October 3, 2022

For more information see the official website.

The Guidelines for drinking-water quality (GDWQ) are updated through a "rolling revision" process which ensures that the GDWQ presents the latest scientific evidence and addresses key concerns raised by countries. This has been achieved by systematically updating sections of the GDWQ as new or updated evidence becomes available.

The purpose of the rolling revision process is to maintain the relevance, quality and integrity of the GDWQ, whilst ensuring their continuing development in response to new, or newly-appreciated, information and challenges.

The rolling revision approach also helps implementation of the GDWQ by national agencies by promoting regular, incremental improvement, rather than attempting to promote the implementation of major, comprehensive changes to drinking-water quality management at once.

Now available for review

Per- and polyfluoroalkyl substances (PFAS), with a focus on PFOS and PFOA, are being considered for the update of the GDWQ. The draft background document is now available for public review.  Comments are welcome using the comment sheet below.
