The object of this study was to produce a single, robust groundwater dataset for South Australia that could be combined with other datasets sourced from elsewhere across Australia. Utilising historical data qualified by minimal metadata is not ideal for geochemical accuracy. However, given the number of samples (~32,000) and their potential utility, it is advantageous to extract useful data from these samples. The South Australian groundwater data was therefore subject to a thorough quality assurance / quality control (QA/QC) assessment. Data that did not pass the assessment was rejected. Though it cannot be assured that all erroneous data had been removed (with particular concern for individual trace metals with concentrations variously expressed in mg/L or g/L), these instances have been minimised, and the data in consequence appear coherent. By combining them into one file having values with consistent detection limits, and by correcting some of the older data for the effects of past analytical method differences when compared to the derivation of recent data, all of the data should now have been rendered readily usable and “seamlessly” comparable. The South Australian groundwater hydrogeochemical data is now being combined with other datasets by CSIRO, in order to map the groundwater chemistry of major geological regions within Australia. Deriving relatively simple parameters showing a spatial variation, such as ion ratios and ion excesses, as well as mineral saturation indices, gives useful input into geological, geochemical and geomorphological mapping.

    Notes: This data release forms part of the Australian Commonwealth Government's “Continental Scale Hydrogeochemistry” initiative that commenced in 2012. The referenced document is the Accompanying Notes to the CSIRO-revised hydrogeochemical data from the SA_GEODATA groundwater dataset. New data collected for the initiative and stored in this dataset was funded by and belongs to the Geological Survey of South Australia. Other historical SA hydrogeochemical data, formerly the property of the South Australian Department of Mines and Energy (SADME), were provided to CSIRO by courtesy of Lloyd Sampson of the South Australian Department of Environment, Water and Natural Resources (DEWNR). The described dataset, plus others created for each of the respective Australian mainland states, are now available online, and users can also contact the authors to obtain copies. The South Australian dataset may be accessed via the link that has been entered into the Related Web URLs field of this index record. Geographic Locality: South Australia Doc No: RB 2015/00035
