Abstract

The objective of this study is to determine the physicochemical, biological condition and their water classification of the Nerus River, to identify the spatial-temporal reelationship between water quality and the pollution by using statistical techniques. The methodology of the study starting  with  analyze  of  13 of  water  quality  parameters  such  as  temperature,  pH,  DO, conductivity, TDS, salinity, turbidity, TSS, COD, BOD, NH3-N and E.coli. Total of three sampling stations (station 6, 7 and 11) were selected and sampling was carried out during dry and wet seasons from 2005 to 2010. Results of the study based on WQI, the river at station 6 and 7 was classified as Class II and Class III, while Class III and Class IV for station 11.Under NWQS, the level most of the parameters remained at Class II and Class III.
