Abstract
Human activities can have impacts on nearby river water characteristics. Consuming water can alter the environment and living organism’s health. Due to various types of pollution sources in the catchment, the objective of this study was to examine both chemical and physical properties of Koya River and its main tributaries. Both point and non-point pollution sources have their inputs to the river including raw sewage and runoff from municipal solid waste landfill, industrial and agricultural areas. Overall, six samples were taken from the point sources of the river catchment. Samples analyzed, important water quality parameters including heavy metals and bacteriological. Most of the selected parameters show positive result, for instance very high bacteria and high part per million (PPM) of some heavy metals, high suspended solids, very turbid water, which exceed the World Health Organization (WHO) Guideline 2017. In the long term, the river water quality may worsen, as human activities will increase with population growth, and yet there is no plan in place to control the pollution course.
