Determination of Chemical Oxygen Demand of Some Selected Wells and Ponds in Bayero University, Kano and its Environs

Abdullahi Muhammad | Lawan Sabo Ahmad

Abstract: Chemical oxygen demand measurements of eight different ponds and wells were determined by back titration method. All samples were analyzed immediately and Chlorides and nitrites interferences were eliminated. The work is aimed at evaluating the pollutional strength of the waters so as to recommendations concerning the detrimental effects that may arise from various uses of such waters. The ponds have 216.59 12.07 while the wells have 74.26 23.31. This further justify the notion that due to a number of factors like washings, agricultural practices and making local bricks ponds were more polluted than wells. Drinking water its high COD directly could results in water borne diseases such as cholera, typhoid, dysentery, etc.
