Description: Hydrochemistry data for groundwater bores and springs were collated from various sources in the SNG region including DEPWS (2023), Geoscience Australia (2024), Gray and Bardwell (2016a, 2016b), McGrath et al. (2021), NT Government (2022), QDRDMW (2023), Schroder et al. (2020) and Trihey and Northey (2021). Given the large variation in temporal range of the data (1948–2022), the most recently acquired data for each bore was used as basis for this assessment. Records with charge balance errors of ≤10% for selected major and minor ions (sodium, calcium, magnesium, potassium, iron, strontium, chloride, bicarbonate, sulfate, nitrate, fluoride, bromide, iodide, and silica) were included for this hydrochemical assessment, totalling 2,154 measurements.A subset of bores have been assigned a source aquifer based on information in existing databases by applying a consistent attribution method (Appendix C in Dixon-Jain et al. 2024).DEPWS (Department of Environment, Parks and Water Security) (2023) Northern Territory bore locations, water quality and groundwater levels [data set], https://data.nt.gov.au/dataset/nt-bore-locations-water-quality-and-groundwater-levelsDixon-Jain P, Bishop C, Lester JE, Orlov C, McPherson A, Pho G, Flower C, Kilgour P, Lawson S, Vizy J and Lewis SJ (2024) Hydrogeology and groundwater systems of the South Nicholson and Georgina basins, Northern Territory and Queensland.
