Impact Of GyadiGyadi Solid Waste Dumping Site On The Quality Of Ground Water Of The Neighbouring Environment

Abstract This work examines the effects of an open dumpsite on the quality of shallow underground water in Gyadi-Gyadi ward of Tarauni Local Government area of Kano State Nigeria. Analysis of the physical and chemical parameters of raw water from four wells located at various distances 100-500m from the dumping site shows that the concentrations of nitrate and phosphate in the analyzed water samples were below detectable limits. Whereas the pH of the ground water is slightly acidic this could be attributed to acidic leachates from the decomposing waste. However most of the water parameters tested fall within the standards of the World Health Organization WHO and the National Standard for Drinking Water Quality NSDWQ. The overburden of the soil underlying the open dumpsite most likely acts as an impervious protective layer that prevents leachates from the waste materials to enter the underground water.
