Bekok River is an important river which supply potable water for the community of Batu Pahat. The highly acidic and metal-polluted Bekok River is of major concern to the water treatment plant operations located at the downstream reach of the river. The problem is presumed to be the results of pyrite oxidation in acid sulfate soils, which occurs in the surrounding area of the river. Based on previous study, the construction of drainage system at Parit Ngamarto which part of Johor Barat Project was one of the possible cause of the presence of the pyrite oxidation. However there was yet no evidence to indicate the process. Hence, this study was initiated to study the occurrence of acid sulfate soil and soil oxidation process at Parit Ngamarto and its influence to Bekok River water quality. River and drainage water samples were collected and analysed for pH, SO42-, electrical conductivity, Al, Fe and Mn concentrations. Soils sampled at various horizons were analysed for soil chemical characteristics. There was evidence that the deterioration of Bekok River water quality is probably due to the results of pyrite oxidation in the acid sulfate soils.
