The study assessed in comparison the concentrations of heavy metals in water samples (n=12) collected from groundwater sources at Keko and Kigogo areas. Three trace elements; Copper, Zinc and Lead (Cu, Zn and Pb). Analysis was done once in dry season and once in rainy season at Ardhi University laboratory. The water samples were taken in 4oc equipment for transportation. Results show low concentrations of Cu and Zn for both seasons and study areas. Pb concentrations were detected beyond the WHO

This presence of high concentrations may be due to urban agriculture activities conducted around the areas surrounding Msimbazi river, and also presence and use of onsite facilities (septic tanks and pit latrines). Discharge and runoff collection from garages and industrial wastes is another reasons thought for this high amount of heavy metals. There is need of adopting cheap water treatment technology for domestic purposes so as to protect people from being affected by the use of untreated water directly.
