Title: Current Research: Bacterial Contamination in Tap Supply
Abstract: 
The number of breakthrough pathogenic activity in water distribution network system is constantly increasing day by day especially at level of consumption. Bacterial growth or survival rate often relates to acidity and alkalinity of water. Sudden changes in pH value and temperature indicates a possibility of present bacterial contaminant in aqueous environment. The observation of pH- and temperature based for tap water supply samples in Malaysia regions therefore was determined. On the basis of the findings, the observed pH value was compared to the recommended range for pH tap and drinking water, which is between 6.5-8.5. A significant spread can be seen among the measured parameters within the range of pH and temperature at 6.00 to 8.65 and 19.20 to 32.00 °C, respectively. There is a statistically significant difference between each sampling regions based on the measured pH value (DF4,145 = 44.79, p < 0.05) determined by one-way ANOVA. The pH value and temperature evidence significant effects by various environmental conditions (air temperature, weather, humidity etc.). There appears to be a negative Pearson correlation between the two water parameters in region WM01 (r = -0.352, p > 0.05), WM02 (r = -0.207,p > 0.05), WM04 (r = -0.334, p > 0.05) and WM05 (r = -0.21, p > 0.05).
