Preliminary study of water quality index of stream at UiTM Pahang branch, Jengka campus / Farah Wahida Mohd Latib ... [et al.]

This study was carried out to determine the preliminary water quality status of stream at
UiTM Pahang Branch, Jengka Campus based on the physicochemical and biological
parameters. The sampling was conducted on rainy season with seven sampling points that
were selected along the stream. A total of 10 water quality parameters were measured and
analyzed using standard methods for the Examination of Water and Wastewater, APHA
(2005). Malaysian Department of Environment Water Quality Index (DOE-WQI) was
calculated and classified according to the National Water Quality Standard, Malaysia
(NWQS). The physical and chemical variables were temperature, dissolved oxygen (DO),
conductivity, pH, total dissolved solid (TDS), salinity, biochemical oxygen demand (BOD),
chemical oxygen demand (COD), total suspended solid (TSS), and ammonia-nitrogen (NH3-
N). Based on Malaysian WQI, the water in this study area is classified as Class III, which is
classified as ‘common of economic value and tolerant species and safe for livestock
drinking’.
