This study was performed to investigate the Natural mineral water quality at 47 sites in Chonnam area, samples were collected spring, summer, fall, winter for a seasonal variation in 1996. The results obtained were summarized as follows 1. The mean of F, pH, HCO$_3$, NO$_3$ -N were 0.19 mg/l, 6. 9, 34.99 mg/l, 1.40 mg/l and those of Na, K, Ca, Mg were 12.1 mg/l, 1.2 mg/l, 7.7 mg/l, 2.1 mg/l respectively. 2. The contents of F were reasonable at Multonggol as 1.35 mg/l and Yongbayui as 0.57 mg/l respectively, but there is no detected at Sidong and detected below 0.1 mg/l at Gubongsan, Hansansa area. 3. According to the geological effect, the content of F was showed higher in granite than in tuff, and index of pH was higher in tuff than in andesite, and content of HCO$_3$ was higher in andesite than in granite. 4. The K and O values were used as index of healthy and delicious water. As a result, thirtyfive sites(74.5%) was decided as healthy and delicious water. 5. The contents of NO$_3$-N were detected over 5 mg/l at Sukchonsa, Gajanggol, Yudalsan, Muchang, Kisan.
