Although the recently published Senate Select Committee’s final report into the management of PFAS contamination is one of the most significant reviews of emerging contaminants in Australia’s recent history, it seems to have raised more questions than it has answered. The final recommendations carry substantial implications for the millions of Australians who drink water every day and have made it clear that much more research is needed to give consumers both clarity and confidence in their tap water.
PFAS, also known as per- and polyfluoroalkyl substances, have received many headlines over recent years, and rightly so, the public has become increasingly concerned due to their persistence in the environment and potential long-term health impacts. Although utilities in Australia generally perform well against existing guidelines, the Committee’s report highlights gaps in national consistency, monitoring frequency and long-term regulatory planning. For end-users, this raises legitimate questions about transparency, confidence, and access to trustworthy information.

One of the report’s core recommendations is the development of a nationally consistent testing and monitoring framework for PFAS in drinking water. It is impossible to determine whether levels are too high if we are not regularly monitoring them nationwide. Currently, testing frequencies vary widely across states, utilities, and even between treatment plants within the same network, with no legal requirements for frequency or publication of results.
A straightforward national approach would ensure that no matter where a consumer lives, whether it be metro, regional, or remote, they can rely on a baseline of regular PFAS testing.
The Committee noted that while many utilities monitor PFAS, reporting practices range from detailed public dashboards to minimal mention in annual water quality reports.
The Committee also strongly recommended the acceleration of PFAS-specific health-based guideline values within the Australian Drinking Water Guidelines (ADWG). While utilities generally comply with current ADWG parameters through ongoing inconsistent testing, the report acknowledges that scientific understanding of PFAS continues to evolve and that there is a real need for further research, especially given the work already completed internationally. As research advances, it is anticipated that safe drinking water thresholds will be reduced to better align with those of other countries, such as the USA.
The report calls on the Australian Government to support utilities with funding to upgrade treatment infrastructure to better manage PFAS, including through testing and removal. This includes advanced filtration technologies, increased sampling, and long-term catchment management. Government funding would help utilities avoid passing these costs on to Australian households through higher water bills. It was acknowledged that remediation and testing are expensive and may be a barrier to a fast solution to PFAS contamination.
While the report does not call for widespread changes to household behaviour, it does highlight the need for caution. It recommends that the industry ensure consumers have access to accurate, science-based advice rather than leaving them to interpret complex chemistry on their own.
For consumers who wish to reduce potential exposure, they have recommended that consumers first stay informed about PFAS levels in their water supply through their utilities or independent testing, and, if they are still concerned, use certified point-of-use or point-of-entry filtration systems capable of removing PFAS.
