-------------------------------------------------------ABSTARCT--------------------------------------------------------------The study involved assessment of the quality of drinking water supplied by water vendors to households in Sabongari area of Kano City in Northern Nigeria. The quality of the water was assessed at commercial sales points, water vendor’s distribution Jeri-cans and household storage tanks. Ninety (90) water samples were collected at 10 locations spread across Sabon-gari and analyzed for physico-chemical and bacteriological parameters. The results obtained were compared with standards recommended by the World Health Organization (WHO), the Nigerian Standard for Drinking Water Quality (NSDWQ) and the European Community (EC). Total Hardness (as CaCO3); Conductivity and Free Chlorine values were not within acceptable limits in most of the samples. Colonies of microorganism were in excess amounts in 9 samples while coliform organism was detected in 19 samples. The percentage of colonies of microorganisms was 27%, 43% and 70% for commercial sales points, hawkers’ Jerry-can, and household storage respectively. Also percentage of samples that tested positive to coliform organism was 10%, 20%, and 33% for commercial sales points, hawkers’ Jerry-can, and household storage respectively. Thus it was concluded that water quality was compromised at the private commercial supply, during hawker’s distribution and in the household storage. It is recommended that the activities of the water vendors need to be regulated and monitored in order to ensure the protection of the public health.
