Please find out the correct Water Quality Index (WQI) formula from Malaysia Department of Environment in order to calculate the WQI using the data from Table 1. State the formula in your answer. Hint: you only need to use 6 parameters to calculate WQI; For SIDO calculation, the value of DO (mg/L) need to be converted to % saturation, which is using this formula, = (DO value/8.3 mg/L) x 100% (Make sure that you show all calculations in detailed) The water quality study of Sungai Way was undertaken by a certified laboratory. The water quality parameter data are presented in the Table 1. Table 1: Water Quality Parameter Results of Sungai Way taken on March 7, 2008. Parameters Station W1 Station W2 pH DO (mg/l) TSS (mg/l) NH3-N (mg/I) BOD (mg/l) COD (mg/l) Faecal Coliform 7.10 3.46 12 6.34 7.41 2.44 8 4.22 4 28 35 10000 6400 (cfu/100ml) As a references : Station W1: 60.1 Station W2: 56.2
