An assessment of water quality in the Kisumu bay area of the Wiman Gulf, Lake Victoria, Kenya

Abstract

The project involved a biologiccl and physico-chemical assessment of lake water quality in Kisurnu Bay in relation to abstraction and treatment for the Kisumu water supply and the impact of the rains on the water quality. At present, most of the water for Kisumu's domestic and industriaI requirements is drawn from the Iake 'ri'hich also acts as a receiving waterbody for the wastewater from Kisumu. The expected increase in population will result in en increase in the demand for water with concomitant increase in the amount of wastewater produced. At the present low levels of water abstrcction from the lake, the raw water quality does not show signs of serious deterioration but with an increase in the dew.and for water, the quality of the lake water may be seriously impaired.
