Australia Australia and New Zealand Release Version 3.1 of the PFAS National Environmental Management Plan

Updating Drinking Water Guideline Values

Australia and New Zealand Release Version 3.1 of the PFAS National Environmental Management Plan

In May 2026, the Australian, state, territory, and New Zealand governments through the Heads of EPA Australia and New Zealand (HEPA) published Version 3.1 of the PFAS National Environmental Management Plan (PFAS NEMP). This plan serves as a nationally consistent framework designed to manage PFAS contamination in the environment across Australia and New Zealand, providing governments with a framework to implement risk-based regulatory measures for PFAS. This update (Version 3.1) reflects new guideline values for PFAS in drinking water based on the Australian Drinking Water Guidelines (ADWG). It also incorporates new guideline values for PFOS (perfluorooctane sulfonic acid) in freshwater based on the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZG).

The updates introduced in Version 3.1 are summarized below.

 

Summary of Updates

Update Affected Sections Description
Reflection of new guideline values for PFAS in drinking water Table 4 in Section 8.6.1 For PFOS, PFHxS, PFOA, and PFBS, this update adds:

  • Tolerable Daily Intake (TDI)
  • Drinking water quality guideline values
  • Recreational water quality guideline values
Reflection of new guideline values for PFOS in freshwater Table 8 in Section 8.7.3 For PFOS, this update:

  • Updates guideline values for freshwater exposure scenarios
  • Updates guideline values for marine water exposure scenarios (interim values reflecting the freshwater guideline values)

 

For reference, the sections of Version 3.0 of the PFAS NEMP and their overviews are outlined below.
