The Study on the Quality of Natural Mineral Water

먹는 샘물 수질에 관한 연구

56 samples were analyzed to understand water quality of the natural mineral water of Korea. The geology according to each sample location is grouped into Precambrian metamorphic rocks, Okcheon metamorphic rocks, Jurassic granite, Cretaceous granite, and Jeju volcanic rocks. Average EC and pH values of the water is 150 μS/cm and 7.3, respectively and water type of the water is mainly Ca-Na-HCO3. Fundamentally, there still is no problem for the water quality of the natural mineral water. Nevertheless, nitrate was detected and arsenic and fluoride contents are near the drinking water standards, it is highly necessary to manage the water quality by installment of casing and grouting or by development of another production well.
