Abstract
Abstract Detailed physical and chemical analysis of domestic water (Borehole) sample was carried out in different residential, industrial and commercial area of the Kano metropolis. It is a common knowledge that today human activities are constantly adding industrial, domestic and agricultural wastes to ground water reservoirs at alarming rate. In the same vein, both the quantity and quality of water are affected by an increase in anthropogenic activities and any pollution either physical or chemical causes changes to the quality of the receiving water body The research used the standard titrimetric UV-spectrophotometer, atomic absorption spectrophotometric (AAS) method to investigate the quality of domestic water for public health protection. A selected physical parameters such as pH, conductivity and chemical parameters such as Ca,Mg,Cl, and NO2, as well as trace metals Cu, Pb, and Zn were analyzed to compared the obtained value with the standard values set by Nigerian industrial standard and World Health Organization. The obtained values of Calcium were 161-191.66 mg/L Copper 3.64-10.04 mg/L,Cl 98-145.4 mg/L, Lead 0.001-0.028 mg/L, Magnesium 85.22-100.4 mg/L, NO2 11.5-21.1mg/L, Zn 2.6-26 mg/L, were all found to be within World Health Organization (WHO), and Nigerian Industrial Standard (NIS 2007) Permissible level (limit). Overall findings the water from all location was found to be safe for domestic consumption. This research suggests that there should be regular monitoring and control of activities especially those leading to ground water contamination.
