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.
