Abstract:

The use of benthic macro invertebrates together with physico- chemical parameters was considered as the reliable method for water quality assessment. This study was conducted to assess the level of pollution in the Rukkisa River water using biological and physico chemical parameters. Three sampling sites were selected, one site was not affected by the coffee processing plant effluent used as reference site and two affected sites in the outlet and downstream 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 and biological analyses. Five physico chemical parameters pH, Temperature, Total Alkality Turbidity and BOD were analyzed. In addition, identification and quantification of benthic macro invertebrates was carried out for each sampling sites. There were a significant differences (p
