PFAS Investigation & Management
All the findings of the investigation are available on the publications page, including detailed reports and factsheets.
Defence has used the findings of the investigation to develop a PFAS Management Area Plan (PMAP). This plan will inform the activities Defence will undertake to manage, monitor and reduce the risk of PFAS exposure on, and around, the Base.
With the conclusion of the investigation, Defence remains committed to working with the community, and to continue being actively involved in the remediation and management of PFAS in Katherine.
