The purpose of this study was to get nano-analysis on heavy metals and volatile organic compounds of spring water located in Gyeongju by using of ICP and GC/MS. In this research we have analyzed the contents of heavy metal(Hg, Cd, As, Zn, Cu, Fe, Pb and Cr6+) and VOC(PCE, TCE, 1,1,1-TCE, benzene, Toluene, ethylbenzene and Xylene) of spring water as specific pollutants for health in order to recognize be suited to as drinking water, had assigned five spring water place in Gyeongju. we have got the data were examined that minerals components, micro inorganic materials, nitrate-nitrogen, dissolved oxygen, temperature, pH, sulfate ion, chlorine ion and fluorine ion. The results of this study are as following ; It has been shown that all of them generally were suited to as standard of drinking water with the exception of total escherichia coli. group and fluorine ion for spring water in Gyeongju. Also some heavy metal, that is, nano unit amounts of asenic and zinc were detected by inductively coupled plasma method, but the rest of them were not detected. On the other hand volatile organic compounds materials were not detected at all. Finally this study must mentioned as following; spring water places in Gyeongju has been relatively not much are compared with other cities, really many people have positive opinion on available of this places because of very closed distance from people's living place and amounts of water quantity are very much to get it. Therefore the expansion of equipments on emergency water feeding which ground water are very clean and safe are good business for life convenience of regional citizens.
