Abstract

River water quality assessment is crucial in order to quantify and monitor spatial and temporally. Malaysia is producing WQI and NWQS indices to evaluate river water quality. However, the study on recreational river water quality is still scarce. A study was conducted to determine selected recreational river water quality area and to determine impact of recreation on recreational stream. Three recreational streams namely Sungai Benus, Sungai Cemperuh and Sungai Luruh in Janda Baik, Pahang were selected. Five sampling stations were chosen from each river with a 200-400 m interval. Six water quality parameters which are BOD5, COD, TSS, pH, ammoniacal-nitrogen and dissolved oxygen were measured. Sampling and analysis was conducted following standard method prepared by USEPA. These parameters were used to calculate the water quality subindex and finally an indicative WQI value using Malaysia water quality index formula. Results indicate that all recreational streams have excellent water quality with WQI values ranging from 89 to 94. Most of water quality parameter was homogenous between sampling sites and between streams. An one-way ANOVA test indicates that no significant difference was observed between each sub index values (p>0.05, α=0.05). Only BOD and COD exhibit slightly variation between stations that would be due to organic domestic wastes done by visitors. The study demonstrated that visitors impact on recreational is minimum and recreation streams are applicable for direct contact recreational.
