The Australian Government’s Trusted Environmental and Geological Information (TEGI) program is a scientific program led by Geoscience Australia. Geoscience Australia is collaborating with CSIRO to deliver regional geological and environmental assessments underpinned by transparent, trusted baseline geological and environmental data. The program will initially focus on the north Bowen, Galilee, Cooper and Adavale geological basins, where there is significant local, state and national interest exists to expand resource development.

This paper focuses on the compilation and integration of resource and groundwater/surface water data into an environmental assessment framework within the Adavale Basin extended region. The Adavale Basin extended region is the geographic area corresponding to the subsurface Adavale Basin plus a 50 kilometre buffer beyond the basin province boundary. The extended region also includes parts of the overlying Galilee, Eromanga and Lake Eyre geological basins and surficial sediments to encompass groundwater, surface water and ecological assets.

The environmental assessment includes a groundwater evaluation that places groundwater data (bore screen depth, groundwater level/pressure, hydrogeochemistry and aquifer yield) from bores and petroleum wells into the context of a regional tectono-stratigraphic framework. Guided by the prevailing depositional environment, the groundwater data were modelled to define key groundwater characteristics. These datasets provide the first fully integrated inter-basin groundwater resource assessment for the Adavale Basin extended region.

The Adavale Basin-scale analysis demarcates zones of groundwater recharge and discharge, inter-aquifer connectivity, groundwater salinity, groundwater levels/pressures and aquifer yield to produce a qualitative groundwater conceptual model. The model highlights the groundwater resource potential of the region and will be publicly available in TEGI’s data repository. CSIRO will build a causal network on the basis of this work that assesses potential environmental impacts of resource and associated industrial development.

This analysis has far-reaching consequences in defining groundwater flow paths targeted to potential resource development in the Adavale Basin extended region, allowing appropriate identification and management of risk to groundwater resources and other environmental assets applicable to industry, regulators, and other stakeholders.
