This study was carried out to changes in chemical and microbiological properties of spring waters in Tongyeoung area. In this paper, ninety spring water samples were collected from 9 station for 11 month to evaluated chemical and bacteriological water quality. Range and mean values of constituents of the samples are as followed; water temperature 5.2-25.8℃, 16.3℃, pH 6.0-7.2, 6.7, total residue 33.6-210 mg/1, 90.6 mg/1, turbidity 0.35-5.48, 1.45NTU, KMnO4 consumed 0.51-4.21 mg/1, 1.39 mgll, chloride ion 6.23-42.5, 16.7 mg/1, phosphate-phosphorus ND-0.04, 0.02 mg/1, nitrite-nitrogen ND-0.02, 0.01 mg/l, nitrate-nitrogen ND-3.56, 1.42 mg/1, ammonia-nitrogen ND-0.20, 0.14 mg/1, dissolved total nitrogen ND-3.78, 1.57 mgll, iron 0.04-0.28, 0.13ppm, zinc 0.03-0.66, 0.20ppm, mangan ND-0.01, allumium 0.14-0.58, 0.39ppm, copper ND-0.01, 0.01, lead ND-0.01, 0.0lppm, Arsenic ND-0.01, 0.0lppm, mercury ND-0.02, chrome not detected, cadmium not detetced respectively. The viable cell counts of the spring waters ranged 5.0760/m1(means 130/m1). Range and mean value of total coliform and fecal coliform MPN's of the spring waters were 0-2,400MPN/100 ml, 73MPN/100 ml and 0-540MPN/ 100 ml, 21MPN/100 ml. Spring water quality was usually poor with viable cell counts exceeding 130 CFU/liter and the coliform counts in spring waters of 73 MPN/liter. Composition of coliform by IMViC reaction was 33.3% E. coli, 15.6% Citrobacter freundii, 35.6% Klebsiella aerogenes and others.
