Preliminary Site InvestigationFurther information on the investigation process can be found at the investigation process page.
The first stage of the investigation, the Preliminary Site Investigation (PSI), has been completed.
Detailed Site Investigation
The second stage of the investigation, the Detailed Site Investigation (DSI), is now complete. This stage involved sampling of soil, sediment, surface water (land and creeks) and groundwater to collect information and better understand how PFAS moves through the local environment.
The Final Detailed Site Investigation Report is available on the publications page.
Human Health Risk Assessment and Ecological Risk Assessment
Based on the findings of the investigation, a Human Health Risk Assessment (HHRA) was undertaken and an Ecological Risk Assessment (ERA) is underway.
These reports will evaluate potential exposure pathways to people, plants and animals. The findings will be used to inform potential actions to reduce PFAS exposure.
The final HHRA report and an Interim ERA are available on the publications page.
