Effluent containing nutrients of nitrogen and phosphorus discharged at industries and Wastewater Treatment Plants (WWTP) are usually swept off through surface runoff into River Kisat (RK) and Nyalenda Wigwa stream (NWS) and finally into the Winam Gulf of Lake Victoria leading to eutrophication. There is lack of information on the efficiency of the Lagoons in reducing the levels of nutrients and the contribution of industries towards pollution, therefore the current study was carried out in order to acquire knowledge that will be useful for management of water quality and related functions.The...

Lake Victoria is eutrophicated with Myxophyceae (blue green algae blooms), Vassia cuspidate griff (hippo grass) and Eichhornia crassipers (water hyacinth) being evident. Several problems have been identified that have arisen out of this eutrophication problem in the Lake, among them being but not limited to water quality. This book therefore, endeavored to substantiate the source of the reported phosphates in Rivers Nzoia, Yala, Kisat and Nyalenda waste water treatment plants in Kenya. This was achieved by assessing phosphate levels in water, sediments and air above the rivers both upstream...
