الملخص:(A study was carried out in March and May 2008 to assess the water quality of the two rivers upon which the Ng Budu Rural Growth Centre (RGH), Saratok depends for water supply. A total of three sampling stations were selected in this study, one for Sg Krian and two for a feeder river, Sg Budu. Eleven water quality parameters were analyzed based on in-situ and ex-situ analysis during study period; and a laboratory analysis were carried out according to the HACH and APHA methods) Results for in-situ water quality parameters are pH (7.03 - 7.13), dissolved oxygen (6.06 - 6.20 mg/L), conductivity (0.020 - 0.025 PS/cm) and temperature (26.8 - 26.9°C). For ex-situ water quality parameters, results for TDS (0.013 - 0.017 mg/1), for TSS (43.20 - 64.33 mg/L); for turbidity (11.6 - 22.5 NTU), and for nutrients (Ammonical nitrogen: 0.049 - 0.085 mg/L; Nitrate: 0.09 - 0.22 mg/L; Phosphate: 0.04 - 0.14 mg/L). Recently, activities such as illegal logging, agricultural activities and development activities have been reported in the surrounding areas of the centre. The impact of these activities have raised some environmental concern to water resources of Sg Budu RGH and adjacent areas which may lead to deterioration of water quality in long term.
