Cooper bore hydrochemical cluster groups

\n## **Abstract** \nThe dataset was derived by the Geological and Bioregional Assessment Program from the hydrochemistry analysis of bores and springs for aquifers within the GAB dataset. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nSelection of samples with values > 0 for all variables: electrical conductivity (EC), pH, Ca, Na, Mg, K, Cl, SO4, HCO3. Normalisation (log-transformation) of all variables, expect pH. Identification of outliers via nearest neighbour linkage and exclusion of samples with dissimilar or unusual chemistry. Attribution of sample to six clusters using Ward’s linkage rule, based on analysis of variance.
