History

Selection 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.
