Spatial Analysis of Water Quality in Parts of Rivers Niger and Kaduna Catchments, North Central, Nigeria.

Abstract

It is understood that human activities have continue to alter the physico-chemical patterns of water and it’s resources, which has resulted into poor water quality in the study area. As comprehensive distribution of water quality parameters in the study area is of great interest, there exist a golden opportunity to consider a study with GIS aided spatial coverage beyond laboratory analytical dimensions. Thus, a total of thirty two (32) samples of water and sediment were collected during rainy and dry season for physico-chemical analysis. Water samples collected were analysed in situ for seven (7) parameters using HANNA multiparameter analyser and eight (8) other parameters were analysed in the analytical laboratory following standard methods. The finding revealed a significant number of parameters analysed were beyond regulatory limits. It is hence recommended that visible policies aimed at ensuring good water quality in the study area are critical for sustainability.
