A Study of some Water Quality Parameters and Metal Concentrations in Engineering and Built Environment Lake Faculty - UKM, Selangor, Peninsular Malaysia during 2019

A study of water quality parameters (temperature, conductivity, total dissolved solid, dissolved oxygen, pH, and water hardness) in Engineering and Built Environment Lake Faculty - UKM, Selangor, Peninsular Malaysia was conducted in January, April, July, and October 2019. Six metals i.e. cadmium, chromium, lead, nickel, zinc, and copper were determined in the most compartment of the lake namely water. The water samples were collected randomly from different sampling points around the lake. The water quality parameters were tested and recorded at each sampling station using Hydrolab Data Sonde 4® and Surveyor ® 4 a water quality multi probe (USA). The metals concentration were determined by Inductively Coupled Plasma Mass Spectrometer (ICP –MS), Perkin Elmer Elan, Model 9000. The water quality parameters were compared with National Water Quality Standard (NWQS Malaysia) while metal concentrations were compared with Malaysian and international standards. Study showed that the averages of water temperature, conductivity, total dissolved solids, dissolved oxygen, pH and hardness values during the months of the study were (29.02°,134.37µS/cm,920 mg/L,5.92 mg/L,8.29 and 37.35CaCO3 mg/L) respectively. The mean metal concentrations in water (in micrograms per liter) based on monthly sampling (in descending order) for Zn, Cu, Cr, Ni, Pb, and Cd were (10.02), (5.36), (2.89), (2.55), (0.73) and (0.080) respectively,
