QLD DNRM Hydrochemistry with QA/QC

## **Abstract** \n\nThis dataset was derived by the Bioregional Assessment Programme. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThe resource contains hyrochemical data which includes field sampling data (e.g. water temperature, pH, EC, DO, alkalinity) and sampling laboratory data (e..g. major ions, trace metals and isotopes). This dataset was extracted directly from the DNRM 'water analysis' table and underwent quality assurance procedure which checked the ionic balance and kept only those samples which balanced to +/- 10%.\n\n## **Purpose** \n\nIt has been created to analyse the hydrochemical trends in the aquifers and coal seams of QLD hydrogeological formations\n\n## **Dataset History** \n\nQLD DNRM bore point data was joined to water analysis data and a spreadsheet of the matching features exported. This spreadsheet was used to provide QA/QC on each water sample by checking the ionic balance and retaining only those samples which retained a +/- 10% balance. Validated data was then returned to a shapefile point dataset and the original spreadsheet retained.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) QLD DNRM Hydrochemistry with QA/QC.
