Multivariate statistical methods, namely: the hierarchical cluster analysis (HCA), and the principal component analysis (PCA) were used to study the spatial variations of the most significant water quality variables and to determine the dominant processes affecting the water quality. Principal Component Analysis (PCA) on the data indicates three factors which explain about 61.004% of the total variance, and suggests temporary hardness of water, salinity of the groundwater and dissolution of bedrock material as the dominant processes affecting the water quality in the study area. Whereas hierarchical cluster analysis HCA indicate two clusters, and suggests salinity of the groundwater, natural mineralization, bedrock dissolution, Temporary Hardness and anthropogenic contamination as the dominant processes affecting the water quality parameters in the study area.

The objectives of this research includes; outlining areas that have high susceptibility to groundwater pollution from surface pollutants and subsurface soils that could be corrosive to buried metal pipes. Twelve (12) vertical electrical sounding (VES) locations were studied using electrode spreads of AB/2 equals to 80 m. OHMEGA Terrameter was deployed to acquire the data by employing Schlumberger array method. The analysis (interpretations) of the results were assisted by employing Win-Resist, Microsoft- Excel and surfer-13 Software The resistivity data interpretation revealed 4 geo-electric layers and the generated distribution curves are of type A, H, K, HK, and QQ. The measured thickness of the overburden lithologic units are in the range of 0.396 m to 27.2 m, w...
