Abstract

This study was carried out to determine the water quality in Tasik SST, UMS. YSI Multiparameter Detection Systems and standard method from APHA, 1995 had been used to obtain the data. Sampling was done twice such at 21 January 2006 for first sampling and 23 February 2006 for the second sampling. Three stations were chosen and the sample taken from the bottom until the surface which is take from 0.5m to 2.0m. The samples were analyzed for Temperature, pH, Dissolved Oxygen (DO) and Biochemical Demand Oxygen (BOD). Temperature, pH and Dissolved Oxygen (DO) were measured in situ while Biochemical Oxygen Demand (BOD) was measured ex- situ. DO was measured initially and after incubation for five days. The BOD5 was computed from the difference between DO, and DO5. Result for the selected parameters are T (29.95-31.33 °C), pH (6.73-6.95), DO (3.3- 6.3 mgl-') and BOD (0.1-3.6mg 1""')
