Physicochemical Characteristics and Environmental Pollution Indicators for Irrigation Agriculture at the Vicinity of River Salanta in Sharada Industrial Areas of Kano State, Nigeria

Abstract

Physicochemical parameters and surface water pollution indicators were investigated using data matrix from nine water sampling points collected in the morning 6.30am and afternoon 2.00pm along the Salanta Stream making the total of 18 water samples. The water samples were taken to the laboratory for physical and chemical analysis of sixteen parameters namely: Ammonium (NH4), phosphate (PO4), Biological oxygen demand (BOD5), Dissolve oxygen (DO), Calcium (Ca), Sodium (Na), Potassium (K), Magnesium (Mg),Chromium (Cr), Lead (Pb) and Chloride (Cl), (mg/l), Nitrite (NO2) and Nitrate (NO3).were analyzed and studied. The results revealed that, the water in the Salanta Stream is controlled by the catchment geology; weathering of silicate minerals from the formation of younger granitic outcrop, dissolve heavy metals and anthropogenic activities from Sharada Industrial areas where effluent is discharge principally with little or no treatment. Therefore, the identification of the main potential water pollution sources in the region by this study will help managers make better and more informed decisions about how to improve the water quality in Salanta Stream for sustainable development.
