Isa Baba Koki, Aminasalihi Bayero

Abstract :

 Rivers and lakes are the main sources of water to public in the cities and villages either by adequate treatment or by direct consumption from the source. But the quality of water bodies has now deteriorated due to urbanization, industrialization, farming and other anthropogenic activities; this is of a great concern because of importance of water to our lives. Water pollution is on the high rise globally and results in health complications and deaths due to consumption of polluted water. Water quality assessment and possible classification encompasses critical analysis and frequent monitoring of chemical, physical and biological parameters that affects aquatic organisms and humans. Heavy metals including Lead, Arsenic, Cadmium, Copper and Zinc may be monitored due to their high toxicity even at low concentrations. Other parameters of interest includepH, dissolve oxygen, alkalinity, biochemical oxygen demand,electrical conductivity, chemical oxygendemand, and nitrates
