Brisbane Airport Tests a Different Endgame for PFAS Cleanup

An industry-led project shows how treating large water volumes could change remediation planning, though regulators remain cautious

Efforts to clean up PFAS contamination at large sites are beginning to shift, as asset owners test methods designed to handle vast volumes of polluted water more efficiently. A closely watched example is underway at Brisbane International Airport, where an industry-led treatment project is informing debate on how future remediation may be carried out.

Decades of firefighting foam use at the airport left so-called “forever chemicals” in groundwater and surface water, producing millions of litres of contaminated water that require management. Conventional approaches typically rely on filters or resins that trap PFAS but then create secondary hazardous waste, adding to disposal costs and extending remediation timelines.

At Brisbane, the airport operator worked with technology provider EVOCRA to deploy a foam-fractionation-based treatment system, according to industry case studies. The approach focused on reducing the volume of contaminated water rather than storing or containing it on site.

About 20mn litres of PFAS-affected water were treated, with most processed to a standard suitable for discharge under existing guidelines. The remaining PFAS was concentrated into a much smaller residual stream, which was transported off site for specialist destruction.

Supporters of volume-reduction methods argue that shrinking the amount of contaminated material can help large site owners better understand their long-term remediation obligations. By limiting the volume that needs ongoing management, they say projects such as Brisbane can improve cost forecasting and reduce future liability.

However, these claims rest largely on vendor data and industry-led case studies. Publicly available, independently audited cost figures for the Brisbane project have not been released.

The airport project is often cited as an early example of how active PFAS mass removal could sit alongside traditional containment strategies. While some regulators and site owners are exploring such options, there has been no broad regulatory move away from containment. Government programmes at airports, including Brisbane, remain centred on investigation, monitoring and risk management.

Significant hurdles remain. Advanced treatment systems require upfront capital, regulatory approval and confidence built through independent verification. Not all contaminated sites are suitable for the same technologies, and capacity to destroy concentrated PFAS waste is still limited in parts of Australia.

Even so, industry participants say projects like Brisbane are influencing how large-scale PFAS remediation is discussed. For a sector long defined by uncertainty, they offer a cautious indication of how cleanup strategies for major assets may evolve.
