So it is of vital importance to monitor and simulate the water quality parameters to ascertain whether the water is still suitable Tor various uses. Therefore in this paper, determination of the BOD and COD in the pond water samples in Lubok Bongor, Kelantan area. The BOD and COD were identified based on dissolved oxygen (DO). The results showed the value of BOD in the range of 2.58 ± 1.17 mg/L which indicated moderately clean and the demand for oxygen by the bacteria is lower. The observed value of COD was 94 .2 ± 2.44 mg/L which showed tbe presence of high concentration of chemical present in pond water. Therefore, based on the results, it can be concluded that the pond water at Lubok Bongor are still safely to use for plants.
