Correlation matrix among the major solute concentrations and physical–chemical properties. Color coding represents the correlation coefficient: large positive values (⪸0.5) are red, intermediate values (0.5 to -0.5) are white, and small values (⪷ - 0.5) are blue. EC*, electrical conductivity; T*, temperature; pH*, hydrogen ion exponent.
