Chemical Quality of Groundwater from Hand-Dug Wells in Jos Metropolis and Environs, North-Central Nigeria.

Abstract

Water samples were obtained from 30 hand-dug wells, distributed in the different rock types within Jos, Nigeria and its environs. These samples were analyzed for chemical parameters. The nitrate elevated values where noticed to be predominant within the most developed areas resulting from sewage, pit latrines, and refuse dumps. The results in this study could be used to structure a public health program that would take into cognizance this threat to human health in health care program planning. Additionally, this study may be of benefit in selection and siting of wells for the purposes of monitoring groundwater quality based on the places where some of these parameters measured above the WHO standard. In light of the data presented in this study, adequate siting and planning of well locations is strongly suggested.
