This study was carried cut to evaluate the water quality of spring waters in Pusan area(see Fig. 1). In this experiment, twenty-five water samples were collected from 5 stations from December 1983 to August 1984. Range and mean values of constituents of the samples are as follows: pH $5.80{sim}7.25$, 6.60; water temperature $6.0{sim}23.0^{circ}C,;12.9^{circ}C$; total residue $33.0{sim}325mg/l$, 121.2mg/l; alkalinity $4.75{sim}51.6mg/l$, 24.1mg/l; hardness $9.47{sim}85.0mg/l$, 30.3mg/l; electrical conductivity $0.495{sim}2.750{ imes}^2{mu}{mho}/cm,;1.239{ imes}10^2{mu}{mho}/cm$;turbidity $0.54{sim}7.80$NTU, 2.04NTU; $KMnO_4$ consumed $0.51{sim}8.47mg/l$, 1.96mg/l; chloride ion $4.91{sim}36.0mg/l$, 12.55mg/l; fluoride ion ND-0.30ppm, 0.08ppm; nitrate-nitrogen ND-8.94mg/l, 1.94m:g/l; nitrite-nirogen ND-0.10mg/l, 0.03mg/l; ammonia-nitrogen ND-0.16mg/l, 0.03mg/l: phosphate-phosphorus ND-0.09mg/l, 0.03mg/l; silicate-silicious $0.42{sim}22.7ng/l$, 7.96mg/l; copper ND-10.5ppb, 2.46ppb; lead ND-22.7ppb, 3.54ppb; zinc ND-103ppb, 21.33ppb; iron $20.3{sim}2,800ppb$, 801.72ppb, respectively. Arsenic, cyan, cadmium, manganese, mercury, chrome and phenol were not detected. Total residue, electrical conductivity, turbidity and chloride ion of station 1 (Milrakdong) were higher than others as 178.1mg/l, $2.127{ imes}10^2{mu}{mho}/cm$, 3.16NTU and 16.32mg/l. The concentration of silicious had a great influence on precipitation. The concentration of fluoride ion of spring waters was lower as 0.08ppm than the criterion for drinking water as 1ppm, while iron was exceed 2.7 times as 801.72ppb.
