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

Dichloroacetic acid in drinking-water

Dichloroacetic acid is included in the plan of work for rolling revision of the WHO Guidelines for Drinking-Water Quality.

Background

The Guidelines for drinking-water quality Final Task Force meeting (Geneva, 2003) recommended that dichloroacetate (DCA) be moved to the rolling revision until new data on its mechanism of carcinogenic action are evaluated and can be incorporated into the risk characterization. US Environmental Protection Agency completed its risk assessment for DCA through the Integrated Risk Information System (including internal and external peer review) and prepared a background document for consideration by the Working Group.

Expected end-product(s):

Revised background document and summary statement, for publication in the first addendum to the Third Edition of the Guidelines.

This is now available as drafts for comments.
