Abstract

Water samples collected from nine sampling points of three different sources (Well, Bore-hole and Stream) within Toto Local Government Area of Nasarawa State, Nigeria were analysed for trace metals and physico-chemical properties. The trace metals Na, K, Cu, Mg, Fe, Ca, Zn, Pb, Cd, As, Se, Cr and Hg were analysed using atomic absorption spectrophotometric method. Alkalinity, pH, temperature, turbidity, conductivity, total solids, total dissolved solids, suspended solids and soluble anions such as phosphate, chloride, nitrate and bicarbonate were the physico-chemical parameters analysed using standard techniques. The results showed that Cd and Hg were not at detectable range for all the water samples. High spatial variations in the concentrations of the metals and physico-chemical parameters determined were recorded. The trace heavy metals were below the deleterious level while the physico-chemical properties of the water were within the required standard limits set by World Health Organisation (WHO) for drinking water except phosphate ion. However source protection is proposed for these waters for the benefit of mankind
