Where is the Investigation up to?
- A Detailed Site Investigation (DSI) was carried out under the Pilot program at Melbourne Airport, as sufficient data was available to support an initial understanding of PFAS on site.
- The DSI recommended further investigations to address data gaps.
- The Melbourne Airport investigation includes a Mass Flux Study with additional Detailed Site Investigations. A Sampling Analysis and Quality Plan (SAQP) is currently being finalised.
- The investigation's focus will be sampling and analysis on airport land to determine the nature and extent of PFAS in soil and groundwater, as well as potential migration pathways between the airport and surrounding land.
Next steps
- Fieldworks at the airport site are expected to commence in March 2025 and take 12 months to complete.
- Following fieldworks, a Mass Flux Study Report and additional Detailed Site Investigation Report will summarise investigation outcomes and identify and recommend next steps.
- A Human Health and Ecological Risk Assessment may be conducted if investigations identify it is required.
- Investigations will inform the development of a PFAS Management Plan for Melbourne Airport that will document the approach to managing risks associated with PFAS contamination at the airport.
