Physical and chemical parameters monitored at eight locations in Challawa Industrial Estate, Kano were analyzed. Principal component analysis (PCA) was used to extract the factors associated with the tannery effluents pollution variability and to obtain the spatial and temporal changes in the effluent quality. Temperature, total solids, total dissolved solids, total suspended solids, conductivity, chloride, sulphide, alkalinity, biochemical oxygen demands and chemical oxygen demands were the main patterns extracted. The spatial analysis isolated six sampling sites showing a possible point source of pollution. Six of the properties (temperature, total dissolved solids, total suspended solids, sulphide, biochemical oxygen demand and chemical oxygen demand) exceed apparent standard limit for industrial effluent discharge in Nigeria for most of the tanneries. Treatments of these effluents are also recommended before discharge.
