Abstract

This study was carried out to determine the water quality in Tasik SST in UMS Lake and 10 determine the pollution level of heavy metals by comparing the analyzed data with the guidelines set in Interim Water Quality Standards for Malaysia. The effects of depth and temperature on parameters in Tasik SST are studied too. Three sampling stations have been choosed and water sampling was carried out two times between January and February, 2006. HASH-APHA and standard method from APHA, 1995 has been used to obtain the data. The following analysis that was carried out in the field (in-situ) was temperature and the analysis in the laboratory (ex-situ) was AI, Fe, SO₄²� and Cl�. The results of the study showed the range of values for the various water quality parameters as follows: temperature (29.95 °c to 31.33°c), AI (0.30 mgl�¹ to 0.71 mgl�¹), Fe (0.39 mgl�¹ to 2.59 mgl�¹), SO₄²� (37 mgl�¹ to 66 mgl�¹) and Cl� (2.13 mgl�¹ to 10.28 mgl�¹). Referring to INWQS for Malaysia (1999), the status of water quality in Tasik SST, UMS is still clean status where agriculture development is permitted except for Fe parameters. The overall quality of the water depends on the parameter which foils the standard.
