Half-widths(Hw) of 17O-NMR spectra have been obtained for many mineral waters, and are found to be different each other. Furthermore, pH values have been found to control Hw. In this paper, the Hws are analyzed by the multiple regression analysis to investigate which element is controlled mostly in the dissolved minerals and pH. Na and pH are found as the above result. Hw changes by EQR irradiation are also investigated and Ca is found as the controlling mineral.
