    Assessment of Wastewater Quality in Nyabugogo Stream; Kigali-Rwanda
    (Kampala International University, Master’s Degree of Environmental Management and Development, 2012-04) Bonane Bahati, Serge
    The study assessed the characteristics of wastewater of Nyabugogo stream highlighting on their sources and the nature of contaminants they constitute as Chemical and Physio-chemical. It was anticipated that the water in the stream had high levels of both solid and liquid contaminants originating from domestic and industrial activities and wastewater discharges into the stream. The objectives of the study were to assess the nature of contaminants in the wastewater discharged into Nyabugogo stream and to identify the composition of contaminants by chemical and physio-chemical characteristics. The study employed both quantitative and qualitative experimental designs to arrive at the results. Water samples from four sites along Nyabugogo stream through Kigali city were collected in well illuminated containers and taken to Energy and Water Sanitation Authority (EWSA) laboratory for analyses. At the sites, many reactive were done directly on the stream waster using conductivimeter and thermometer to determine Electrical Conductivity, Temperature and pH respectively. The results of the study were analyzed using Stata version 8.0 and Pearson correlation coefficient was complicated to establish the relationship between metal concentration and physico chemical characteristics. The results showed that a lot of water contaminants such as Copper, Magnesium, Iron, Potassium, Calcium, Nickel, Chloride, Sulphate, and Zinc were contained in the wastewater and once they reach the stream, the characteristics of the stream water change. Thus the stream water constituted contaminants from both domestic and industrial/commercial origins
