- Abstract
Based on results and analysis, the values of ten parameters namely; Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Turbidity, Nitrate, Nitrite, Chlorine, Fluoride, pH and coliforms bacteria in the study stations were influenced by evaluate water quality during the three months of study periods. Hence, this research aimed to assess and evaluate the 8 drinking water condominium stations at Kelana Jaya area, Selangor, Malaysia. The average value of nitrate, turbidity, chlorine, fluoride was higher of tap water in some condominiums especially ST3, ST4, ST5, ST6 and ST7. The highest value of this physicochemical parameters at stations ST5 (pH 8.6, nitrate 0.16 mg/L, turbidity 1.5 NTU, chlorine 1.2 mg/L, and fluoride 1.65 mg/L) and ST6 (pH 8.5, nitrate 0.15 mg/L, turbidity 1.6 NTU, chlorine 1.95 mg/L and fluoride 1.73 mg/L) which slightly higher than drinking water standard. With same aim of this investigation to determine the level of total viable counts and fecal coliform bacteria of taps waters before using filters which indicate that there were 3 stations have higher value ST3 (before 563 and after 5 CFU/100 mL), ST5 (before 579 and after 7 CFU/100 mL) and ST6 (before 582 and after 15 CFU/100 mL) respectively. The house filter in most physicochemical parameters is more accurate than commercial filter (WFS) but for total viable counts and fecal coliform bacteria found that commercial filter is more effective and accurate than housefilter.
