Abstract

Tasik Puteri, a man-made lake with an area of 131 hectares is located in Dungun District, Terengganu. The lake was once used for iron ore washing process and has now turned into a recreation centre for people living nearby. Nearly, a decade of industrial scale iron mining operations in Bukit Besi has passed and has caused an impact on the region's surface water quality. However, no information with respect to the water quality status of this lake has been provided to the public. The aim of this work is to evaluate the physicochemical quality of the lake water. Parameters measured were temperature, pH and dissolved oxygen. Water samples from 14 sampling point with different depth were taken. All the parameters were measured in situ by using Hach Water Quality Analysis Kit and was done according to the guidelines of Department of Environment (DOE) Malaysian water quality assessment with respect to Interim National Water Quality standards (INWQS). Results showed that the pH for almost all sampling point is around 3-4, temperature around 30 oC and dissolved oxygen less than 10 mg/L. Based on DOE Water Quality Index Classification the lake was classified as polluted against class IV. This shows the lake is not suitable for recreational activities such as fishing and canoeing but more to irrigation.
