PFAS Investigation &
Management Program

RAAF Base Pearce

Community Notice


On 7 October 2021, it was announced that Defence, in consultation with the Western Australian Government, will progress works to connect West Bullsbrook properties to town water.

Defence has explored a range of options to address water supply needs of affected residents in West Bullsbrook, including the installation of rainwater tanks, point of entry and point of use filters for homes and bores, as well as connecting properties to town water.

Connecting West Bullsbrook properties to town water is considered the best outcome for the community.

Defence will update residents on this project as new information is available.

A media release on the announcement has been published with further details.

Community update

Defence has published two ongoing monitoring interpretive reports. The reports share the lastest results of our program of ongoing monitoring, which is tracking the location and concentration of PFAS in the Management Area. For a short summary of the findings of the reports, please see the related ongoing monitoring factsheet.

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.
