This project investigates potential groundwater contamination causes, pathways and vulnerability to understand onshore gas water quality impacts for south east South Australia.

The research achieves a realistic quantification of groundwater contamination risks in gas development areas in south east South Australia, providing improved knowledge for regulators, industry and community.

This study considered three plausible contamination scenarios and for each scenario, water flow and solute transport modelling estimated peak concentrations at risk receptors (i.e. nearby groundwater bores). Results showed that it is very unlikely that plausible contamination events would result in high contaminant concentrations at groundwater receptors in the vicinity of the gas development considered in this study, due to dilution rates over distance to receptor sites and solute degradation within soils and aquifers.

Deep learning emulators for groundwater contaminant transport modelling

This research project investigates the feasibility of using deep learning emulators to improve the efficiency of groundwater computer modelling (generalised flow and contaminant transport model) based on the hydrogeology of an aquifer located in South Australia, where contamination risk from on-shore gas development needs to be assessed. Study results improve understanding of hybrid modelling and show that accurate, efficient and scalable deep learning emulators can be achieved.
