Abstract

Summary Wide Range of human and anthropogenic activities impinges on the urban environment in most cities in Nigeria, to degrade the quality of water resources. Some of these activities (daily discharge of solid and liquid waste, industrial effluent, and physo-chemical weathering processes) are discharged directly on sources of water supply to the populace of Onitsha. Based on this problem, this paper examines the quality of water from hand-dug wells in Onitsha. 15 wells water samples were collected during the month of January, July, and August with the aid of sterilized containers. And sent to the laboratory for analyses, results showed that wells that are located close to dumpsites are more polluted in terms of turbidity, TSS, CaCo2 conductivity salinity acidity, Pb, Fe and bacteriological quality of the well water. Also most of the hand-dug well water qualities are unsafe for human consumption, because they are generally above the WHO maximum acceptable threshold. Since this source of water form one of the major source of water to the inhabitants, there is need for purification proper disposal of waste, public education of the health implication of waste/impure water and other management measures.
