PFAS contamination in Australia's water supply
PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals that have been linked to various adverse health effects, including thyroid disease, certain types of cancer, and liver damage. Due to their persistence in the environment and the human body, they have been dubbed "forever chemicals". PFAS contamination in water supplies is a significant issue in Australia, with the country being identified as one of several "hotspots" for these toxic chemicals.
The Australian government has not imposed a complete ban on all PFAS chemicals, but it has implemented measures to control their use and reduce their environmental and health impacts. The government is working closely with affected communities to help them understand PFAS contamination and provide advice on reducing exposure. The Department of Defence has also initiated a comprehensive PFAS Investigation and Management Program, identifying around 27 defence sites for investigation or management.
Despite these efforts, PFAS contamination remains a challenge. PFAS chemicals are highly mobile in water and can travel long distances from their source. They have been detected in surface and groundwater, with levels in some areas exceeding safe drinking water criteria. The National Health and Medical Research Council (NHMRC) has developed the Australian Drinking Water Guidelines to ensure the safety of drinking water, but these guidelines only apply to treated water, leaving some sources of drinking water unregulated.
To address PFAS contamination in water supplies, Australia has phased out firefighting foams containing PFAS at airports and defence sites, promoting PFAS-free alternatives. Water providers are encouraged to publish annual water quality reports and provide up-to-date information to the public. Individuals can also take proactive steps by staying informed about PFAS updates from environmental agencies and health departments and advocating for stricter regulations and cleanup efforts.

Health concerns and PFAS-related illnesses
PFAS, or per- and polyfluoroalkyl substances, are synthetic chemicals found in many products and are known for their persistence in the environment and their resistance to natural degradation. They are commonly referred to as "forever chemicals" because they do not break down in the environment or the human body.
While PFAS have not been completely banned in Australia, specific actions and regulations have been implemented to control their use and manage their impact. This includes significantly restricting their use in firefighting foams, which have been a major source of environmental contamination.
PFAS exposure has been linked to several health problems, although the understanding of the human health effects of long-term exposure is still evolving. Here are some of the health concerns and PFAS-related illnesses that have been identified:
- Cancer: PFAS exposure has been associated with an increased risk of certain types of cancers.
- Thyroid issues: PFAS can interfere with thyroid hormone production, leading to potential thyroid disorders.
- Hormonal imbalances: PFAS have been linked to altered sex hormone levels, which can have a range of health consequences.
- Kidney problems: Reduced kidney function has been observed in some cases of PFAS exposure.
- Liver damage: PFAS contamination has been associated with liver damage in some individuals.
- Reproductive issues: PFAS exposure may lead to low birth weight and potential effects on foetal development, impacting reproductive health.
- High cholesterol: Prolonged PFAS exposure has been linked to high cholesterol levels, which is a risk factor for cardiovascular disease.
It is important to note that the health effects of PFAS exposure can vary depending on individual factors and the level and duration of exposure. While research is ongoing, the Australian government recommends reducing exposure to PFAS wherever possible as a precautionary measure.
If you are concerned about potential PFAS exposure, you can refer to the advice provided by local health authorities and the Australian Government Department of Health. Additionally, staying informed about PFAS investigations and regulatory actions can help you make informed decisions to minimise your risk of exposure.

PFAS in everyday products
PFAS, or Per- and Polyfluoroalkyl Substances, are synthetic chemicals that are used to make products resistant to heat, stains, grease, and water. They are human-made and almost everyone will have some exposure to them in their lifetime. PFAS are bio-accumulative and do not break down naturally in the environment. They are also highly mobile in water, which means they can travel long distances from their source point.
In Australia, PFAS have been widely used in firefighting foam in Defence Force bases, airports, and industrial areas. Increased environmental levels of PFAS have been detected at these sites. PFAS have also been used in consumer products such as non-stick pans, rain jackets, cosmetics, sunscreen, and stain-repellent sprays. Most Australians are likely to have very low levels of PFAS in their bodies from exposure to these everyday items.
PFAS have been linked to negative health outcomes, including increased cholesterol and uric acid levels in the blood, and an increased risk of testicular and kidney cancer. There is also evidence of negative immune and cardiovascular impacts, as well as negative impacts on fetal and infant growth. However, the understanding of the human health effects of long-term PFAS exposure is still developing.
While there are no current restrictions on PFAS in food or trade in agricultural or aquaculture products, food safety regulators can set maximum limits for contaminants in the environment if they consider it necessary to manage exposure through food. People living near PFAS-contaminated sites may be advised to reduce their consumption of homegrown produce to minimize PFAS exposure.
Some Australian states, such as South Australia, have taken steps to ban PFAS-containing firefighting foams to minimize environmental and human health risks. The Australian Government has also been working since 2002 to reduce the use of certain PFAS and prevent or reduce environmental and human PFAS exposure.

Australian government's response to PFAS
Australia has not imposed a complete ban on all PFAS chemicals, but specific actions and regulations have been implemented to control their use and manage their impact. PFAS, or per- and polyfluoroalkyl substances, are commonly referred to as "forever chemicals" due to their persistence in the environment and the human body without breaking down. Over time, these substances can accumulate in water, soil, and living organisms, leading to widespread environmental contamination and potential adverse health effects in humans, including thyroid hormone disruption, cancer, liver damage, and effects on foetal development.
Recognising the risks associated with PFAS, the Australian government has taken several measures to address the issue. Firstly, they have phased out firefighting foams containing certain types of PFAS at airports and defence sites, promoting PFAS-free alternatives. This is a significant step as firefighting foams are a major source of environmental contamination. The Department of Defence is actively investigating and managing PFAS contamination at identified defence sites, with around 27 sites currently under investigation.
Airservices Australia is also conducting its National PFAS Management Program, assessing sites where aviation fire and rescue services have been provided. Additionally, the Australian Government has allocated $130.5 million for the PFAS Airports Investigation Program at airports where PFAS-containing firefighting foams were historically used. State and territory governments are also conducting their own investigations of state-owned sites, such as fire-fighter training sites.
The Australian government is working closely with affected communities to help them understand PFAS contamination and its implications. While the specific advice may vary depending on local circumstances, community members are advised to follow the recommendations provided by the investigating agency's human health risk assessment and state or territory advice for their area. The Australian Government Department of Health and local health authorities provide general advice and information on exposure and health effects.
To manage existing contamination and prevent further contamination, the Australian Government PFAS Taskforce was established, operating from 2017 to 2022. This task force supported the coordination and oversight of government responses to PFAS contamination. The use of PFAS in various products has been decreasing due to rising health concerns and regulatory actions. Water providers are required to publish annual water quality reports, and the Australian Industrial Chemicals Introduction Scheme (formally NICNAS) has published several alerts on PFAS, recommending restrictions on certain PFAS chemicals.

PFAS contamination sites in Australia
PFAS (Per- and polyfluoroalkyl substances) contamination has been detected at numerous sites across Australia, with the Australian Government committing $130.5 million to the PFAS Airports Investigation Program. PFAS contamination has been found in sites where firefighting foam containing PFAS has been used, including military bases, airports, and industrial areas. PFAS has also been detected in homes, vehicles, and where Scotchguard has been used.
PFAS chemicals have been linked to various diseases, and they are now ubiquitous in the environment, concentrating in waterways and sediments. PFAS can enter the food chain through contaminated groundwater and food grown using contaminated water. The Australian Government is working to manage existing contamination and prevent further spread, with state and territory governments sharing information to address the issue.
In Western Australia, sites contaminated with PFAS must be reported to the Department of Water and Environmental Regulation (DWER) under the Contaminated Sites Act 2003. PFAS investigations in WA include sites associated with the use and/or storage of aqueous film-forming foams (AFFF), as well as landfills, wastewater treatment plants, and waste disposal facilities.
The Australian Government has developed health-based guidance values for PFOS, PFOA, and PFHxS, with the National Health and Medical Research Council (NHMRC) publishing guidance for PFAS in recreational water bodies. The PFAS National Environmental Management Plan (PFAS NEMP) provides a framework for the environmental regulation of PFAS-contaminated sites, with the aim of responding to emerging research and knowledge.
Despite the efforts to manage and prevent PFAS contamination, the Australian Government has not banned PFAS, even though it has been prohibited in other countries.
