Groundwater Quality Appraisal in Southern Parts of Kaduna State, Nigeria

Abstract

Assessment of groundwater quality fro m the rocks of the Basement Co mplex in the southern parts of Kaduna State, Nigeria was carried out. Forty samp les fro m boreholes, hand-dug wells and springs were collected during the dry and raining seasons for chemical and bacteriological analyses. The essence of the study is to assess the quality and the portability of the groundwater using the World Health Organization (WHO) standards for drinking water. The results of the water samples analyses indicate a lo w total mineralization. However, results of some hand dug wells suggest that the water might have been contaminated due to human activities and closeness to pit latrines/soak-away and other domestic refuse dumps. The Piper's trilinear and Schoeller diagrams showed that the groundwater in the study area can be classified to be Ca-Na-HCO3 fresh water.
