The first stage of the investigation, the Preliminary Site Investigation (PSI), has been completed.
Detailed Site Investigation
The Detailed Site Investigation (DSI) has been completed and involved sampling on-base and in the surrounding region.
Human Health and Ecological Risk Assessment
Based on the initial findings conducted for the DSI, Human Health and Ecological Risk Assessments (HHERA) has been conducted. The HHERA evaluated potential risks to the human population and ecology, and informed actions to mitigate risks. The HHERA was completed in November 2017. The HHERA findings can be found in the HHERA Report.
Based on the outcomes of the HHERA, Defence is currently working on an Addendum to the HHERA to clarify and seek additional information. The Addendum to the HHERA is expected to be complete by mid-2018.
A PFAS Management Area Plan will be developed to manage potential PFAS exposure to human health and the environment posed by the legacy PFAS contamination both on-base and off-base.
