Naval Communication Station Harold E Holt Areas A & B PFAS Investigation
Summary of the Investigation
In September 2017, Defence commenced a detailed environmental investigation into the presence of per- and poly-fluoroalkyl substances (PFAS) on and in the vicinity of Naval Communication Station Harold E Holt Areas A and B.
The objective of this environmental investigation is to identify the nature and extent of PFAS in the environment from the use of legacy fire-fighting foam at the Base.
There are three main stages to the investigation:
Preliminary Site Investigation
The first stage of the investigation, the Preliminary Site Investigation (PSI), has been completed.
Detailed Site Investigation
The Detailed Site Investigation (DSI) has commenced and will involve sampling on-base and in the surrounding region. A detailed report will be prepared and shared with relevant government and regulatory bodies as well as the community. The DSI is expected to be complete in late 2018.
Human Health and Ecological Risk Assessment
The DSI findings will be used to inform the requirement to conduct a Human Health and Ecological Risk Assessments (HHERA). If required, the HHERA will evaluate potential PFAS exposure risks to the human population and ecology.
Further information on the investigation process can be found at the investigation process page
The findings from the investigations will be used to identify and prioritise site specific management actions to address PFAS contamination.
Defence is committed to regularly updating the community throughout the investigation. As well as community information sessions, updates are provided through the project website, direct mail and information sheets as new information becomes available.
