Sixty‐nine groundwater samples were analyzed for six chemical parameters. Partial and simple correlation coefficients for these parameters indicate that partial coefficients are superior to simple coefficients in establishing geochemical relationships for the aqueous system evaluated. The improved reliability arises from the ability of partial correlation analysis to hold outside factors that may be affecting the two variables of interest, constant.
