Abstract

The Semenyih River is one of the most important rivers in Selangor, Malaysia,because it functions as a resource for domestic water supply, fishing, and recreation. It has been adversely affected by urban and industrial wastes since the early 1990s. This study assessed the contamination status of the Semenyih River based on the National Water Quality Standards for Malaysian rivers (NWQS) and the national Water Quality Index (WQI) classifications. Although 10 of the waterquality parameters were within the recommended levels for the NWQS, levels of phosphate (PO4), E. coli, and total coliform bacteria were found to exceed the threshold. The Semenyih River is polluted by human activities from its upstream section (contamination by E. coli, coliform bacteria, and PO4) and is therefore characterized as Class III based on NWQS classificationBased on WQI, the Semenyih River was classified as slightly polluted and placed in Class II for Malaysian rivers at all sampling stations except stations 5 and 7, which were more polluted and therefore classified under Class III. According to WQI, the river is suitable for recreation and permissible for body contact.
