CLM - Groundwater Chemistry outputs from multivariate statistics


The dataset was derived by the Bioregional Assessment Programme from "QLD DNRM Hydrochemistry with QA/QC" and "NSW Office of Water Groundwater Quality extract 28_nov_2013" data provided by the Qld DNRM and NSW Office of Water. 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.

The dataset contains the outputs of a multivariate statistical analysis conducted on groundwater chemistry data for different river basins or sub-regions within the CLM bioregion. The analysis was conducted using Statgraphics software. Only samples that passed the QA/QC checks (e.g. charge balances within +-5%) were included in the analysis.

Dataset History

The original datasets were clipped to the CLM bioregion. After an initial data quality check, only those samples that met the criteria (e.g. charge balance between + and - 5%) were included in the multivariate statistical analysis. Multivariate statistical analysis was conducted on the remaining dataset (i.e. those samples that did not meet the QA/QC criteria removed), resulting in different groundwater chemistry groups.

The methodology is described in more detail by Raiber et al., (2012).
