Description: The process of attributing aquifer and aquifer province information to bores is critical for the interpretation of hydrogeological data, as it identifies the hydrostratigraphic unit that occurs within the production zone of a groundwater bore, i.e. the subsurface zone where the bore is open to the aquifer and draws groundwater. Assigning aquifer attribution improves comparison of groundwater data from bores across the investigation area, providing confidence that groundwater data relates to the same hydrostratigraphic unit.This dataset provides information on the hydrostratigraphic aquifer and aquifer province attribution to the screened/open intervals for groundwater bores in the Kati Thanda - Lake Eyre Basin (KT-LEB) region. The geology and hydrogeology of the KT-LEB region are discussed in detail in Evans et al. (2024).Confidence in aquifer attribution (in particular for Cenozoic hydrostratigraphic units) varies considerably and is largely dependent on the varying levels of geological understanding that occur across the KT-LEB. For instance, often Cenozoic sediments are not differentiated into individual hydrostratigraphic units. Whilst more general, the aquifer province attribution is useful, particularly where either aquifer attribution is poorly defined or for providing another (broader) level of grouping for hydrogeological data. Aquifer province attribution is particularly useful if an area includes several stacked or laterally distributed sedimentary basins. Bit of these cases apply to the KT-LEB. Approaches for determining aquifer attribution for bores are outlined in various publications, including the Bioregional Assessment of the Galilee Basin (Evans et al. 2018), the Geological and Bioregional Assessment of the Cooper Basin (Evans et al. 2020), the Broken Hill Groundwater and Regolith Geochemistry project (de Caritat et al. 2022) and the regional stratigraphic correlation studies of the Great Artesian Basin, Lake Eyre Basin and Upper Darling Floodplain region (Norton and Rollet 2023).
