Community update

West Bullsbrook Scheme Water Supply – Expression of Interest to connect your property

Property owners within the RAAF Base Pearce PFAS Management Area were recently sent an update on the provision of scheme water infrastructure.

To refine the design, Defence needs to know the number of properties likely to connect to scheme water as that number will influence the flow of water within the network, which can impact water quality and pressure. For the network to be feasible, a minimum number of properties will need to opt-in.

If you have decided to opt-in, please complete the West Bullsbrook Scheme Water - Expression of Interest form, or return a hard copy using the reply-paid envelope we provided. If you need to take additional time to decide, or require further information, please let us know.

On 21 June 2022, Defence held two Community Information Sessions to answer your questions and provide additional details about the proposed network. To view information from those sessions, please visit the RAAF Base Pearce Community Consultation page. Further answers to questions raised during those sessions will be published in the coming weeks.

RAAF Base Pearce

PFAS Investigation & Management

In November 2018, Defence completed a detailed environmental investigation into the presence of per- and poly-fluoroalkyl substances (PFAS) on and around RAAF Base Pearce.

Investigation Reports and factsheets are available on the publications page.

The outcomes of the investigation have been used to develop a PFAS Management Area Plan (PMAP) that outlines the best management and remediation solutions for the unique circumstances on and around RAAF Base Pearce.

Defence is undertaking a range of activities to address PFAS contamination on and around RAAF Base Pearce. This includes:
  • eliminating PFAS exposure pathways through the provision of alternative water;
  • reducing PFAS leaving the base through remediation works at the Grounds Maintenance Area and the current and former Fire Training Areas;
  • conducting a mass flux study to establish a detailed understanding of PFAS migration from the base, and to inform the need for any further remedial works; and
  • continuing to monitor the nature and extent of PFAS contamination on, and around, RAAF Base Pearce through the Ongoing Monitoring Program.
With the conclusion of the investigation, Defence remains committed to working with the community, and to the appropriate and responsible remediation and management of PFAS on and around RAAF Base Pearce.

Detailed Site Investigation

Complete
Jul 2018

The Detailed Site Investigation involved sampling of soil, sediment, surface water and groundwater, to better understand how PFAS moves through the environment.
