A Study on Water Quality Status of Varsity Lake and Pantai River, Anak Air Batu River in UM Kuala Lumpur, Malaysia and Classify it based on (WQI) Malaysia

Abstract

Rivers and lakes are primary sources of water for towns and villages. However, the quality of these water bodies is currently deteriorating due to urbanization, industrialization, farming, and other anthropogenic activities. This study was conducted within January 25th to November 26th 2017at designated points at Pantai River, Anak Air Batu River, and Varsity Lake, University of Malaya, Kuala Lumpur, Malaysia, where the physic-chemical and biological characteristics were determined in order to increase the statistical basis of these regions. In the physic-chemical evaluation of the water samples, diverse parameters were measured, such as the pH, turbidity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Suspended Solids (SS), ammonia, phosphate and nitrate attention, and biology. These parameters were compared with the Water Quality Index (WQI) standards of water quality. Overall, the result showed that the DO, BOD, COD, and SS fall within classes II, III, while Ammoniacal Nitrogen (NH3-N) falls within classes II, IV, and V, and pH and temperature fall within class I. The study area reported moderate levels of pollution between classes I and IIA due to urban activities. The results showed that the water collected from the study area was unsuitable for human consumption due to the significant presence of microbes.
