PFAS: Australian Perspectives

Following the earlier detection of PFOS and PFOA in groundwater at two Australian Defence Force Installations, the Australian Department of Defence established a national program of PFAS Environmental investigations in 2015. This program has commenced Detailed Environmental Investigations, including Human Health risk assessments and Ecological risk assessments, at 27 Installations across the country. At the end of 2018, 13 investigations including risk assessments have been completed with the remaining 14 investigations expected to be completed by the end of 2019.

Where investigations have been completed the Installations have transitioned from Investigation sites to Management sites with each site having a PFAS Management Area Plan developed. These plans describe the proposed actions to manage elevated risks arising from PFAS contamination on and from Defence installations. Primarily, these actions will focus on limiting people’s exposure to PFAS and limiting migration of PFAS from Defence installations.

Management actions implemented to date include ground and surface water treatment plants, excavation of high concentration source areas, drainage clearance works and waste water treatment initiatives. Communities surrounding these Defence Installations are expecting timely action on management and remediation activities, and the Australian Department of Defence is seeking to adopt promising and proven technologies which mitigate the risk of migration and commence environmental clean up activities.
