Australian Drinking Water Guidelines - Public Consultation on Draft Guidance for Per- and Polyfluoroalkyl Substances (PFAS)
Overview
The National Health and Medical Research Council (NHMRC) is inviting stakeholder feedback on draft guidance on per- and polyfluoroalkyl substances (PFAS) as part of the Australian Drinking Water Guidelines (the Guidelines).
NHMRC has drafted an update of the PFAS Fact Sheet within the Guidelines that includes revised and newly established health-based guideline values. The draft PFAS fact sheet is supported by a NHMRC Statement on PFAS in drinking water, which provides a summary of the findings that informed the update.
The PFAS reviewed as part of this update include perfluorooctanoic acid (PFOA); perfluorooctane sulfonic acid (PFOS); perfluorohexane sulfonic acid (PFHxS); perfluorobutane sulfonic acid (PFBS) and hexafluoropropylene oxide dimer acid and its ammonium salt (GenX chemicals).
Further information on the NHMRC Review of PFAS in Australian drinking water is available on the NHMRC website.
What are the Australian Drinking Water Guidelines?
The Guidelines are part of the National Water Quality Management Strategy and are designed to provide a framework for safe, good quality drinking water, how it can be achieved and how it can be assured.
Since the Guidelines were published in 2011, NHMRC maintains the Guidelines through a rolling review process to ensure they represent the latest scientific evidence on good quality drinking water. Updates to specific sections, including the chemical fact sheets, are prioritised based on expert advice and availability of new or emerging scientific evidence.
What is changing?
Based on a review of the available evidence, NHMRC is proposing updates to the health-based drinking water guidelines for several PFAS as noted below.
PFAS | Current Guideline Recommendations | Potential Guideline Recommendations for Public Consultation |
---|---|---|
PFOA | Based on human health considerations, the concentration of PFOA in drinking water should not exceed 560 ng/L. | Based on human health considerations, the concentration of PFOA in drinking water should not exceed 200 ng/L. |
PFOS | Based on human health considerations, the sum of the concentrations of PFOS and PFHxS in drinking water should not exceed 70 ng/L. | Based on human health considerations, the concentration of PFOS in drinking water should not exceed 4 ng/L. |
PFHxS | Based on human health considerations, the concentration of PFHxS in drinking water should not exceed 30 ng/L. | |
PFBS | No health-based guideline value in the current Guidelines. | Based on human health considerations, the concentration of PFBS in drinking water should not exceed 1000 ng/L. |
GenX chemicals | No health-based guideline value in the current Guidelines. | No health-based guideline value is considered necessary for GenX chemicals at this time. |
How can I make a submission?
Submissions should be made via the online form below.
The form invites responses to specific questions on the draft PFAS Fact Sheet and draft NHMRC Statement on PFAS in drinking water. Please note the form does not allow for attachments to be uploaded.
You do not have to provide comments on all questions. Please focus on the question/s of most interest to you and/or your organisation.
Where possible, please refer to the relevant page number of the relevant document when providing comments.
The closing date for submissions is 22 November 2024.
Why your views matter
The information provided during this consultation will help us strengthen the management framework for drinking water quality across Australia. Your feedback will assist us in making this guidance as user friendly and relevant as possible.
At the end of the consultation period, all submissions will be considered by the Water Quality Advisory Committee in consultation with the NHMRC.
It is expected that the guidance material will be published as part of the Guidelines in 2025.
