Determination of physicochemical parameters and heavy metals content of water samples from domestic and Kaduna River in Kaduna Metropolis, Kaduna State

Water is very essential for the survival of all living things both plants and animals depend on the availability of water. The aim of this work is to determine the physicochemical parameters and heavy metals content of water samples from domestic and Kaduna River in Kaduna metropolis. Standard method were used for physicochemical parameters and atomic absorption spectrophotometer were used for heavy metals of the water samples. The range of temperature (25.1±0.78°C and 27.6±0.21°C), pH value (6.30±0.29 and 8.46±0.06), turbidity (5.05±0.07m and 9.94±0.08m), the respective water conductivity were 5.95±0.49μS/cm and 98.0±2.82μS/cm, the TDS (4.15±0.35mg/l and 0.71±0.01mg/l), DO content recorded (1.18±0.01mg/l and 8.55±0.12mg/l), COD value were 1.08±0.11mg/l and 6.81±0.11mg/l and BOD (1.08±0.11mg/l and 6.81±0.11 mg/l) domestic and Kaduna River. In heavy metals, copper and cobalt concentrations were higher in domestic and Kaduna River water. The concentration of Zinc in domestic water (0.090±0.044ppm) was higher than that observed in Kaduna River (0.027±0.004ppm). Lead were 0.264±0.011ppm and 0.129±0.07ppm, Cadmium were 0.331±0.013ppm and 0.329±0.019ppm, respectively. The results showed that the water analyzed from domestic and Kaduna River water were within limit except chemical oxygen demand which was below, lead, cadmium and cobalt were above.
