This project looked to understand and quantify aquifer reactions occurring due to re-injection of CSG water, and their impacts on water quality.

This resulted in methods for predicting water quality changes resulting from CSG water re-injection.

The final outcome shows that injecting large volumes of treated CSG-produced water at suitable locations within the Surat Basin is unlikely to cause any harm to groundwater quality.

However, to achieve this the water has to be treated adequately to eliminate the risk of polluting groundwater with arsenic – a generally immobile toxic element that occurs naturally in some of the rock formations being considered for re-injection.

Final report, October 2016.
