Right from World creation, there is no way man as one of the living organisms can live without water – bathing, cooking, drinking etc. Thus, drinking water is one of the necessities for all living organisms and one of its basic requirements is cleanliness. Dumping of waste causes environmental pollution by deteriorating the water quality and ultimately affects the health of local inhabitants – This is very rampant in developing countries in which Nigeria as a country is no exception. This study was carried out in Ado-Ekiti Metropolis of Nigeria with intention of analyzing and assessing the effects of dumped waste site on (ground) water qualities. Some water samples were taken from the selected waste dumping site and some laboratory tests were conducted on them. The results showed the presence of leachates and E – coli bacteria in both surface and subsurface water. Conclusively, the waste-dumping site has great negative effects on the water quality of Ado – ekiti. It shows that the water is not fit for consumption and may not be suitable for some Civil Engineering works unless undergo rigorous treatment. There is also need for quick intervention by government and individuals to avert outbreak of epidemic diseases.
