Soil Treatment Plant

In 2018 Defence entered into a collaborative arrangement with Ventia to trial a soil treatment technology it had been developing. This trial included the design, operation and maintenance of a PFAS soil treatment plant at RAAF Base Edinburgh.

In total, the plant treated over 10,000 tonnes of PFAS impacted soil from RAAF Base Edinburgh, and 1,500 tonnes transported from RAAF Base Williamtown.

The plant successfully removed 90% of PFAS mass from clayey soil and 98% of PFAS mass from sandy soil. 99% of the soil treated from Edinburgh was reused onsite.

The soil treatment plant worked by washing the contaminated soil in a solution which removes the PFAS. The concentrated PFAS removed was then sent off-site for management or destruction at a licensed facility.

Fire Training Area Water Treatment Plant

Defence has engaged Enviropacific Services Pty Ltd to install and operate an on-base water treatment plant to remove PFAS from groundwater beneath the current Fire Training Area.

Water is extracted from the aquifer and following treatment is then re-injected back into the aquifer. Extracted PFAS will be transported off-site for destruction at a licensed facility.

The plant has been installed and commissioned, and has been treating groundwater since mid-August 2019.

2020 Water Sampling Results

The Water Sampling Summaries track the PFAS concentrations against the limits defined by the relevant adopted drinking water screening criteria. They include results for perfluorooctanoic acid (PFOA) and the sum of perfluorooctane sulfonic acid (PFOS) and perfluorohexane sulfonic acid (PFHxS).

The water quality data is drawn from water samples on both untreated and treated water. The summaries of water sampling results can be downloaded below.
