Physicochemical assessment of water quality in selected borehole in Anyigba Town, Kogi State, Nigeria

Abstract

Borehole is an important source of water on which many people in Anyigba metropolis depend for their livelihood. The people of Anyigba in Kogi East of Nigeria depends on this source of water for domestic purpose and other uses hence the need to investigate the quality of the water to ascertain it suitability for domestic and other uses. The physicochemical properties of the water were analyzed using different standard analytical techniques: UVspectrophotometer was used to analyze Nitrate, Sulphate and Ammonia in the water samples. Also, Flame photometer was used to analyze Calcium, Potassium and Sodium in the water samples. the results of the physicochemical analyzed showed the following ranges: pH 6.5-7.6mg/L, Temperature 26-28^oC, Conductivity 10-20us/cm, Dissolved oxygen 0.49- 9.3mg/l, Total alkalinity 10-20mg/l, Total hardness 18-40mg/l, chloride 28.4-71mg/l, Acidity 210mg/l, Sodium 33.5- 38.4mg/l, Potassium 9.90-10.70mg/l, Calcium 92.5-167.8mg/l, Nitrate 26-35mg/l, Ammonia 79-107mg/l and Sulphate 42.5-78mg/L. Some of the parameters were observed to be within the permissible limit stipulated by the World Health Organization, there is still need to protect the underground water bodies against any in flush of pollutants.
