Civil engineering (General) This study was carried out to determine the status of the water quality condition in Cempaka Lake, Bandar Baru Bangi, Selangor, Malaysia. Seven sampling stations were selected to represent the water quality condition of the lake. The sampling was carried out in two different times; the first sampling was in June 2010 and the second sampling in August 2010. A total of fifteen water quality parameters was selected, analyzed in-situ and ex-situ, and classified based on WQI and NWQS Classifications. Results for in-situ water quality parameters are: pH content ranged from 6.13 to 6.92; DO from 1.63 to 4.94 mg/L; temperature from 26.02 to 28.37 ºC and conductivity from 94 to 213μS/cm. For ex-situ water quality parameters are: BOD from 0.38 to 2.4 mg/L, Escherichia coli from 120x102 CFU/100mL to 403x102CFU /100mL; nitrite from 0.06 to 0.99 mg/L, nitrate from 1.0 to 1.8 mg/L; ammoniacal nitrogen from 2.00 to 2.84 mg/L; phosphate from 0.21 to 0.56 mg/L; sulphate from 21 to 35 mg/L; COD from 9.3 to 69 mg/L and TSS from 1.8 to 33.3 mg/L; oil & grease from 5.7 to 11.8 mg/L; hardness from 13.89 to 35.57 mg/L.
