Jandakot Airport

Site Investigation

  • Environmental Resources Management Australia Pty Ltd (ERM) is the contaminated land specialist leading the Program investigation at Jandakot Airport.
  • The Program investigation at Jandakot Airport commenced in March 2024 and is anticipated to take approximately two years to complete.
  • The investigation will address potential sources of PFAS at the airport, as well as potential migration pathways to receptors both on and off airport.
  • JBS&G Australia Pty Ltd is the accredited contaminated land auditor engaged by the department to independently audit the investigation to ensure compliance with relevant regulations, national guidance and best practice.
  • The department is engaging with relevant state agencies to support the review of key investigation reports and plans.
  • Airport participation in the Program is voluntary. Jandakot Airport signed a Memorandum of Understanding with the department to join the Program on 25 July 2023.
PFAS Airports Investigation Program (Tranche 2) Jandakot Airport

Where is the Investigation up to?

  • The Jandakot Airport investigation will include a Preliminary Site Investigation (PSI), Sampling Analysis and Quality Plans (SAQP), Detailed Site Investigation (DSI) and Mass Flux Study.
  • 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 adjacent residential land.
  • The PSI report, Mass Flux SAQP and DSI SAQP have been prepared by ERM and reviewed by the department, the contaminated land auditor and the Jandakot Airport Investigation Consultation Forum.
  • On airport fieldworks commenced late 2024 and are expected to continue throughout 2025.
  • Off airport fieldworks, including residential property sampling, commenced in February 2025.
  • ERM visited around 180 residential properties and, where the resident consented, undertook sampling (informed by a Water Use Survey).

Next steps

  • Investigation fieldworks will continue throughout 2025 and include the installation of additional groundwater monitoring wells on and off airport.
  • All off airport residents that consent to sampling under the Program will receive a copy of the sample analysis from their property. Relevant WA authorities will be consulted about residential sampling results and will provide associated guidance and advice to residents as appropriate.
  • ERM will engage with airport tenants and off airport residents impacted by the investigation works ahead of any scheduled activities.
  • Following fieldworks, a Mass Flux Study Report and 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 the investigation identifies it is required.
  • The investigation will inform the development of a PFAS Management Plan for Jandakot Airport that will document the approach to managing risks associated with PFAS contamination at the airport.
