Abstract: The research aims to examine the coliform bacteria contamination in Kut Ta Po canal that flow through of Watthana nakhon Sub-District Municipality zone, Watthana nakhon District, Sa kaeo Province. The sampling site was divided into 8 points. The water sample was collected in two times, in August 2020 of rainy season sample and in December 2020 of drought season sample. The water quality was conducted by analyzing total coliform bacteria, fecal coliform bacteria, physical, and some chemical characteristics such as pH, temperature, dissolved oxygen, EC, total dissolved solids, turbidity, transparency and BOD. The results showed that total coliform bacteria was 75->1,100 MPN/100 mL, fecal coliform bacteria was 11-38 MPN/100 mL, pH was 6.16-7.60, temperature was 25.2-28.8 ๐C, dissolved oxygen was 1.99-6.02 mg/L, EC was 150-200 μs/ cm, total dissolved solids was 120-150 mg/L, turbidity was 97.5-172.2 NTU, transparency was 30.1-56.1 cm, and BOD was 1.22-13.24 mg/L. The water quality of Kut Ta Po canal was ranged in the limit of water quality standard in surface water sources, category 3, except drought season, DO was lower while, BOD was exceeded. The obtained information of this study could be used as a guideline for preventing and solving of water pollution problem that occur in the future.
