Abstract

Introduction: All types of farming activities,· including run-off from pesticide and fertilizer use, and from feedlots, animal manure and crop residues are one of the causes of agricultural pollution which causing water pollution. Objective: To assess the level of microbiological E.coli, . . total coliform and water quality including pH, turbidity, COD, BOD and Tbs along Bertam River, Cameron Highlands. Methodology: The study was conducted along Bertam River, Cameron Highlands consists of 14 sampling points. All physicochemical parameters including pH, turbidity and total dissolved solid were analyzed by using YSI (model 6600-m). Chemical Oxygen Demand (COD) measurement was analyzed using colorimetric method. Biological Oxygen Demand (BOD) was done by 5 days incubator. The E.coli concentration was determined by membrane filtration technique. All E.coli isolates from the three regions were deposited in the collection of Institut Penyelidikan Hidraulik Kebangsaan Malaysia (NAHRIM) Laboratory. Results: pH values, E.-coli, Total Coliform, TDS within the normal threshold range for Malaysian river water while turbidity and COD exceed the National Water Quality Standard (NWQS). Turbidity was significantly higher in lower Bertam compared to the upper Bertam. For correlation between concentrations of physicochemical properties and total coliform with E.coli concentration, the resulting Pearson's correlation coefficient, r of 0.634 indicates a moderately positive correlation. There is significant difference between turbidity and bacteria concentrations. Conclusion: The study showed the E.coli colonies and total coliform for all the 14 sampling points were within the guideline value. Both turbidity and COD exceeded the limit. Correlation matrix showed a strong positive correlation between pH and turbidity with total coliform. Periodic monitoring needed for further to monitor the water quality. Keywords: Water Quality, physicochemical parameters, microbiological parameter, E.coli, Total Coliform, river pollution
