The study was carried out on a weekly basis for a period of four months within the rainy season (June-September) in the year 2013. Three sampling stations were established along the river courses (upstream, midstream and downstream of the cassava processing site). Results of physico-chemical analysis of the water samples showed that cassava processing caused a decrease in dissolved oxygen and pH and an increase in biochemical oxygen demand (BOD), chemical oxygen demand (COD), total microbial count (TMC), temperature, phosphates, sulphates and nitrates. Using a water quality index (WQI) in classifying water quality of the streams show that the values of the index are generally greater than 2 at sampling points A (downstream) and C (upstream) across the three streams indicating that the water quality at sampling points A and C in the three water bodies is acceptable. However, at sampling point B (mid stream) across the three water bodies the water quality index ranges between 0.6 and 1.06 indicating that the water quality at sampling point B across the water bodies is poor.
