Abstract
Understanding the connection between aquifers, aquitards, and groundwater-dependant ecosystems remains a key challenge when developing a conceptual hydrogeological model. The aim of this study was to develop a systematic strontium isotope (87Sr/86Sr) fingerprinting framework of rocks and water within the sedimentary Surat and Clarence-Moreton basins (SCM basins) in eastern Australia – an area of extensive coal seam gas development and high potential for aquifer and groundwater-surface water connectivity. To do this, new groundwater samples (n = 298) were collected, analyzed and integrated with published data (n = 154) from the basins' major sedimentary, volcanic and alluvial aquifers, includ..

This publication integrates data collected between 2011 and 2022 as part of multiple independent research projects by authorship team members from different organisations and with funding provided to different organisations from multiple sources. Funding to this research was provided through CSIRO's Gas Industry Social and Environmental Research Alliance (GISERA) with contributions from the Australian Government's Department of Industry, Science and Resources. GISERA is a collaboration between CSIRO, Common-wealth, state and territory governments and industry established to undertake research on the impacts of onshore gas exploration and development on the environment, and the socio-economic costs and benefits. For information about GISERA's governance structure, projects and research findings visit https://gisera.csiro.au. This research was also supported through CSIRO strategic funding. The Queensland Office of Groundwater Impact Assessment (OGIA) was established in 2011 to undertake independent cumulative impact assessments of coal seam gas (CSG) , conventional oil and gas, and mining activities, focusing on the Surat, Clarence-Moreton and southern Bowen basins. Technical assessments and management arrangements are revised every three years and reported in an Underground Water Impact Report. OGIA is funded by a levy on resource tenure holders (htt ps:// www.ogia.water.qld.gov.au/about) .
