Abstract

Poor access to improved water and sanitation in Nigeria remains a major contributing factor to high morbidity and mortality rates among children under five. The use of contaminated drinking water and poor sanitary conditions result in increased vulnerability to water-borne diseases, including diarrhoea which leads to deaths of more than 70,000 children under five annually[5]. This study was carried out in Zango ward of Bade local government area of Yobe state. Water samples were collected in a sterilized one litre plastic gallon and transported to Yobe state University science laboratory in a container filled with ice for physicochemical analysis. The samples were collected from Borehole, Well, Hand pump and WASH borehole respectively.  Atomic absorption spectrophotometer (AAS) was used to determined level of, manganese, sodium,  cadmium, total dissolved solid ,chromium, zinc, iron and arsenic concentration in the samples, and P.H meter was used to determine the P.H levels of the samples while Colorimeter SMART3 was used in analysing turbidity, chloride, sulphate and nitrate respectively. The study found that out of thirteen (13) parameters tested, nine (9) were found to be within the drinking water standard of world health organization from all the sources: these include zinc, sodium, manganese, P.H, Total dissolved solid,chloride, sulphate, nitrate and arsenic, whileit is recommended that Government should start regular monitoring and assessment of water quality to ensure its palatability, households should be encourage to purify their drinking water before consuming.
