| description | Anoxic condition of reservoir often results in the presence of sulphide in the water. Warm water column in Batang Ai Hydroelectric Dam is well-suited for the production of sulphide in the water column. Temperature, pH, dissolved oxygen (DO) and sulphide concentrations were measured at S locations at 3 different depths in the reservoir. Highest temperature recorded was 30.31 °c at STI while the lowest been recorded was 24.75 °C at ST4. The pH values were found to rang!; from 6.63 to 7.37. The sulphide levels were lower at the 1 m depth compared to 14 m and 27 m. They ranged from 0.3 to 6.7JlglL. Most of the stations (ST2, STI, ST4 and STS) were found to have higher concentration of sulphide at the 14 m compared to 27 m except at STI. Sulphide concentration was measured highest at 14 m of STS (14.7 IlgIL) and lowest at 1 m of ST2. The surface water concentration of sulphide at STI differ significantly with ST4 (p=0.024) while at both 14 m and 27 m depth, the concentrations of sulphide at STI were significantly. lower than STS. One way ANOV A shows that there were significant differences among stations at every depth (1m, p=O.028; 14 m,p=0.029; 27 m, p=O.028). Hence, the concentrations of sulphide were found to be different at every locations as well as different water column depending on the sampling sites. |
