Pathway for toxicant default guideline value publication

The publication of default guideline values (DGVs) on the Water Quality Guidelines website involves a publication approval process (refer to Figure 1) that includes initial approval to develop a DGV, development of the DGV and final approval.

All toxicant DGVs published in the Water Quality Guidelines from 2018 onwards, whether funded through the Water Quality Guidelines or contributed by third parties, are subject to a period of public comment.

When draft DGVs have successfully passed through the public comment phase, they will be final, and published on the website as a DGV (refer to Figure 1).
