Abstract:

The use of benthic macroinvertabrates together with physico- chemical parameters are considered as the reliable method for water quality assessment. The main objective of this study was to determine the water qualities of Meta River using biological and physico chemical parameters. One reference site which is less affected by the beer factory effluent discharge and two affected sites in the down stream were used to collect the water samples. A total of three water samples were collected from the three sampling sites. Each water sample was subjected to various physico-chemical analyses. Nine physico-chemical parameters pH, temperature, E.C, TDS, salinity, turbidity, nitrate-nitrogen, nitritenitrogen, phosphate were used. There were significant differences in most of the physicochemical parameters (p
