Sydney Tap Water Now Contains 31 PFAS Chemicals, Sensitive Testing Shows
Sensitive Testing Finds 21 More PFAS Types in Sydney’s Tap Water
Australian researchers have discovered 21 new PFAS “forever chemicals” in Sydney’s tap water, bringing the total detected to 31 distinct types. The breakthrough came from the University of New South Wales team using advanced, sensitive methods to analyse samples from four water catchments.
While most PFAS levels remain extremely low, “like one drop in 20 Olympic pools” and well within Australian drinking water guidelines, the US EPA considers that there is no safe PFAS level due to long-term health risks. Some Sydney water samples were found to be near or above international safety benchmarks.
Significantly, the team detected a PFAS chemical never before reported in tap water anywhere in the world, likely originating from food packaging, and another rare breakdown product of firefighting foam found in Australia for the first time.
Sydney Water assures residents that water treated at its nine filtration plants is safe and compliant with local guidelines, yet the findings highlight a need for broader, ongoing PFAS monitoring and international scientific cooperation.
Sensitive testing is revealing more PFAS chemicals in our water than ever before. While levels are currently low, the discovery emphasises the need for ongoing vigilance, research, and updated standards to safeguard public health.

Puraffinity partners with the U.S. Army ERDC to evaluate Puratech G400, an advanced adsorbent for PFAS removal, through lab and field trials comparing its performance and cost-effectiveness to existing PFAS treatment technologies
An exclusive panel featuring Puraffinity CEO Vincent Caillaud, who will join industry leaders to discuss cutting-edge solutions for combatting PFAS, “forever chemicals”, in drinking water. With PFAS contamination presenting urgent health challenges due to their extreme persistence, mobility, and health impacts at trace levels, this session will spotlight the realities of PFAS in water supplies, the latest science driving regulatory change, and the next generation of removal technologies.
WEFTEC 2025 is the world’s largest annual water quality conference and exhibition, held September 27–October 1, 2025, at McCormick Place in Chicago. It gathers over 20,000 water professionals from 100+ countries to explore cutting-edge water technologies, attend technical sessions and workshops, and network with sector leaders. The event features a massive exhibition of advanced solutions, educational opportunities, and speciality pavilions focused on topics like sustainability and digital innovation. Our CEO, Vincent Caillaud , and CCO, Neal Megonnell , will be in attendance.
In the Building World-Class Teams webinar series, Henrik Hagemann and Jessica Middlesmiss will be discussing how to Create Cultures that Scale
Neal Megonnell brings over three decades of experience in various leadership, technology and sales roles in the carbon industry to his new position at Puraffinity.
