Consultation has concluded

A Groundwater Prohibition Area was established in the stage 1 area on 3 February 2022 from the Edinburgh RAAF Defence Precinct to Port Wakefield Road.

The second stage from the Precinct area to the Barker Inlet was established on 23 February 2023.

The prohibition is required to protect bore users from known per-and-polyfluoroalkyl substances (PFAS) contaminated groundwater and the future migration of this contamination.

The purpose of a groundwater prohibition area is to protect both current and future landholders from accessing contaminated groundwater via a bore on their property.

Please view the interactive map below as the depth of the prohibition varies depending on the location within the groundwater prohibition area.

  • What is the testing protocol used in PFAS testing for soil and water?

    Crooga asked over 2 years ago

    Thank you so much for your question.

    The soil and groundwater was assessed during the site contamination audit  of the Edinburgh RAAF Defence precinct, completed in October 2020, to determine the nature and extent of PFAS contamination both in the soil and groundwater. No further assessment of soil will be undertaken unless a new source of contamination is identified.  Groundwater will continue to be assessed twice a year to monitor the movement of the groundwater PFAS plume in the four aquifers upper aquifers in the area.  This biannual monitoring program will be reviewed at the end of this year to determine the continuing frequency of the groundwater monitoring, which is dependent on a statistical analysis of the plume stability.

    Kind regards,

    EPA
