    This study was performed to investigate the water quality of some natural mineral springs in Busan. Samples for this study were collected at fifty sites during a year, from March 2000 to February 2001. We found out that health hazardous components(Pb, F-, As, Se, Hg, CN-, Cr6+, Cd, NH3-N and NO3-N) and aesthetically influential components(pH, hardness, dry residues, KMnO4 consumption, Cu, Zn, Fe, Mn, Al, Cl- and SO42-) were not found or much lower than water quality guideline for drinking water. The overall tendency of mineral and anion contents were like this : Na > Ca > Mg > K and Cl- > SO42- > NO3-N > F- respectively. Samples for this study have tendency that Na and Cl- are higher than other provinces because this sampling area is adjacent to sea. The correlation coefficient r between Cl- and Ca, Mg, Na, K were 0.3424, 0.4772, 0.4310, 0.1527 respectively, and r was 0.1176 between NO3-N and Cl-. And there was high correlation between hardness and alkalinity(r=0.8108).The K and O index suggested by Hashimoto was followed: delicious water(58%) > not belong to any group(34%) > healthy and delicious water(6%) > healthy water(2%).
