Jakara River, northwestern, Nigeria has been found to be polluted by\r\nvarious sources of pollution associated with excessive land use. This study attempted\r\nto identify the sources of pollution in the Jakara Basin using principal component\r\nanalysis and factor analysis (PCA/FA). Four different sampling points were designed\r\nalong Jakara River and surface water samples were collected for sixty days. Fifteen\r\nphysico-chemical parameters were analyzed which includes: water temperature,\r\nturbidity, salinity, conductivity, pH, nitrates (NO3-), ammonia-nitrate (NH3-NL), total\r\nsolids (TS), suspended solids (SS), dissolved solids (DS), 5-day biochemical oxygen\r\ndemand (BOD5), chemical oxygen demand (COD), dissolved oxygen (DO),\r\nphosphates (PO43-), and chloride (Cl). PCA/FA extracted five principal components\r\n(PCs) explaining 70.7% of the total variance of the raw data. PCA/FA showed that\r\nJakara River is influenced mostly by organic and nutrients (anthropogenic) pollution\r\nfrom domestic wastewater and little contribution from geology of the area, erosion\r\nand farmland run-off. These results provide fundamental information for the\r\nauthorities to take sound action for developing better water pollution control and\r\neffective management of river water quality in the area.
