同海大学 Pollution of Lake Victoria Tongji University ● Most cities lack the proper and complete operational capacity to completely dispose industrial waste. Non-point source pollution makes it even more difficult for regulations to be enforced and pollution sources determined. Deforestation and soil erosion deteriorates ecosystem and ruin water quality. ● Poor governance and low levels of public awareness are accelerating the pollution
