Abstract
The aim of this research was to analyze the physico-chemical parameters and the total microbial indicators in water. Water samples were taken in July 2013 from four
sampling sites at Siak river in Tualang, Meredan. The results showed that the range of pH, TDS, and nitrate in water samples were 6.03-6.13, 32 mg/L, 0.413-0.752 mg/L
respectively, which below maximum allowable level, according to PP No. 82, 2001. The water temperature and phosphate content ranged between 29-30oC, 0.427-2.356
mg/L, which were higher than the standard. The level of Coliform and E. coli contamination in water samples were 1.5×102-5.4×103
CFU/mL and 0.2×102
-0.6×103
CFU/mL, respectively. The level of total bacteria contamination in water samples was
2.3×103-1.5×105
MPN/mL while the fungi contamination was 1×102-1×103
CFU/mL.
