The main purpose of this study is to search the water factor which influences to occurrence of the total coliforms. Occurrences rate of the total coliforms and the E. coli were 57.9%, 10.5% in 2007 and 47.4%, 23.7% in 2008 respectively. According to the result which examines the correlation analysis and a regression analysis, most the water factor which is effect was Na+(0.497, p<0.05) in appearance of the total coliforms and was Cl-(0.622, p<0.01) in appearance of the E. coli. The water factor that simultaneously influences to the total coliforms and the E. coli appearances was the Cl-. The predictable regression formula for appearance rate of the total coliforms was expressed as 0.462+0.028 [Na+]-0.644 [COD(Mn)]-8.889[PO4-P](R=0.930, R2=0.866, adjusted R2=0.839, p<0.05), and that of the E. coli was described as -0.012+0.004[Cl-](R=0.622, R2=0.387, adjusted R2=0.351, p<0.05).
