Singleton Military Area
PFAS Investigation & Management
In December 2021, Defence completed a detailed environmental investigation into the presence of per- and poly-fluoroalkyl substances (PFAS) on and in the vicinity of the Singleton Military Area.
All 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. This plan informs the activities Defence will undertake to manage, monitor and reduce the risks of PFAS exposure on, and around, the Base.
