Abstract: 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 [ $PO_4-P$ ](R = 0.930, $R^2$ = 0.866, adjusted $R^2$ = 0.839, p<0.05), and that of the E coli was described as -0.012 + 0.004 [ $Cl^-$ ](R = 0.622, $R^2$ = 0.387, adjusted $R^2$ = 0.351, p<0.05).
