Objective: The purpose of this study was to investigate the distribution of mineral components, health and taste index for water supply plants, spring water located in northern Gyeonggi area and bottled waters in market to analyze Ca, K, Mg Na, Si, F<sup>−</sup> and SO<sub>4</sub><sup>2−</sup>. Method: The samples were source and tap water in 15 water supply plants over 9 river basin, 172 spring water and 20 bottled water. The Ca, K, Mg Na and Si were analyzed by ICP-OES. The F<sup>−</sup> and SO<sub>4</sub><sup>2−</sup> were determined by Ion Chromatograph. Then, taste and health index were calculated using Hashimoto equation. Results: The average concentration of major minerals showed in same order of Ca > Na > Mg > K for all kinds of drinking water from water supply plants, spring waters and bottled waters. Total concentration of major minerals (Ca, K, Mg, Na) was calculated that showed 26.79 mg/L of tap water, 21.81 mg/L of spring water, 32.94 mg/L of bottled water on average. So, the spring waters indicated the lowest minerals sum. The tap water from water supply plants was categorized to Group I, II for 33.3, 44.4% according to K-index and O-index. Otherwise, spring water was classified as Group I, II for 44.0, 46.3%. Conclusion: According to the results of K and O-index, water from water supply plant showed higher K-index which means good for the health. Otherwise, spring water indicated higher O-index that people can feel more delicious than tap water. Futhermore, the mineral distribution of source water from water supply plants and spring water had indicated high correlation with geological effect.
