Treatment of PFAS contaminated groundwater – Rutherford
Rutherford, NSW 
Environmental Treatment Solutions (ETS) / Suez 
Dec 2020 – September 2022SciDev were contracted through Suez and Environmental Treatment Solutions (ETS) to design a temporary solution to capture and treat any contaminated surface water runoff on the Truegain site. The site was formerly an oil refinery, with a known source of hydrocarbons, oil and per-and poly-fluoroalkyl substances (PFAS). The site was inactive from 2016 with no management or containment of leaking storage tanks or hazardous run-off water into the local environment.
The project presented several challenging criteria:
Utilise remote monitoring andminimise on-site personnel, to capture on-site water.
Manage and treat wastewater with varying concentrations of PFAS, hydrocarbons and oil, resulting in a batch treatment methodology process to pre-treat the contaminated water before the filtration process.
Providing a cost-effective treatment solution off-site
To date, the project has treated over 4.4ML, which is an incredible achievement for a batch treatment plant. SciDev are in the process of undertaking upgrades on the WTP at the ETS facility to provide more automation and to manage any future co-contaminants in the waste stream.
