Work in progress and drafts for the ongoing revision of the guidelines

1,4 Dioxane

Background

1,4-Dioxane was not considered in any previous versions of the Guidelines for Drinking-water Quality. The Guidelines for drinking-water quality Final Task Force meeting (Geneva, 2003) recommended that the new background document that had been prepared on 1,4-dioxane for publication in the third edition be moved to the rolling revision in order to deal with substantial reviewers’ comments concerning its mechanism of action and guideline value derivation.

Expected end-product(s)

Background document and summary statement for inclusion in first addendum to third edition

This is now available as a draft for comment.

Comments on the draft would be welcome and should be submitted by e-mail before 31 October 2004.
