Focusing on the investigation of the suitability of the standard for palatable water from Ministry of Welfare in Japan ("Oishiimizu no youken"), chemical analyses and sensory tests were done on about 82 samples of well, spring, river, and commercial mineral waters in Hiroshima district and other districts in Japan. In simple regression analyses between sensory tests and chemical compositions, relatively good correlations could be obtained for organic matter, total hardness, and iron which are included in this standard, and bicarbonate. Using these 4 chemical compositions, multiple regression analyses were done. The multiple regression coefficient for the water from Hiroshima district (n=47) and from other districts (n=35) were 0.8217 and 0.8401, respectively. At the same time, statistical accept ability was satisfactory in every regression analysis suggesting that these regression analyses could be established. These results suggest that the standard for potable water from the Ministry of Welfare in Japan might be approved. In addition, it was confirmed that evaluate of potable water might be possible using these 4 chemical compositions, organic matter, total hardness, iron, and bicarbonate.
