The National Health and Medical Research Council (NHMRC) plays a pivotal role in safeguarding public health by developing the Australian Drinking Water Guidelines (the Guidelines). These guidelines serve as a crucial resource for water regulators and suppliers, offering comprehensive advice on monitoring and managing drinking water quality across Australia.
One significant focus of the Guidelines is addressing contaminants like per- and polyfluoroalkyl substances (PFAS). PFAS are persistent chemicals that do not break down easily in the environment, leading to their accumulation in soil, water, animals, and even humans. Given their enduring presence and potential health risks, governments across Australia advise the public to minimise PFAS exposure while ongoing research continues to investigate their impacts on human health.
To ensure the Guidelines remain relevant and reflect the latest scientific knowledge, NHMRC reviews prioritised sections of the Guidelines with advice from the Water Quality Advisory Committee. This rolling review process aims to maintain a high standard for the management of drinking water supplies and provide authoritative guidance on what constitutes safe and good quality water, how it can be achieved, and how it can be maintained.
Currently, NHMRC is conducting an independent review of the health-based guideline values for PFAS. This update is part of NHMRC’s commitment to keeping the Guidelines current and scientifically sound. The review, funded by the Department of Health and Aged Care, includes examining recent international PFAS guidance and reviews, such as the recommendations from the United States Environmental Protection Agency (USEPA), to determine if the current NHMRC advice remains appropriate.
The review is already underway and is anticipated to be completed by late 2025 and public consultation is a key component of this process and is scheduled for late 2024 to early 2025. This approach aligns with the Commonwealth's commitment to continuously consider evolving evidence and international guidance as they become available.
It is important to note that the Guidelines are advisory, not mandatory or legally enforceable. Their adoption and implementation are at the discretion of each state and territory, which integrate the Guidelines within their own administrative and legislative frameworks.
For detailed information on how these Guidelines are applied in different states and territories, stakeholders are encouraged to contact their respective drinking water regulators or health departments.
