Environmental impact assessment of area around Ilokun waste dumpsite was carried-out in other to evaluate the possible impact of the waste dumpsite on soil and ground water in and around Ilokun environs. Thirteen (13) soil samples were collected using a hand auger. The soil samples were collected at horizon B of the soil subsurface. The soil samples were designated S1 to S13. Samples S1 to S12 were collected in and around the waste dumpsite while sample S13 was collected far away to serve as the control point. Seven (7) water samples were collected in and around the waste dumpsite. Five (5) water samples from hand dug well (HDW) and two (2) water samples were collected from boreholes (BH). The concentration of cations such as K, As, Zn, Rb, Sr, Zr, P, Ni, Th and Y which ranges from 542 to 1065ppm, 70 to 1131ppm, 166 to 1257ppm, 113 to 1094ppm, 251 to 714ppm, 1500 to 12914ppm, 24 to 161352ppm, 500 to 2444ppm, 441 to 1034ppm and 42ppm to 219ppm respectively. Which were found to exceed the control point, which has a concentration of488ppm, 25ppm, 125ppm, 63ppm, 100ppm, 1471ppm, 0ppm, 424ppm and 421ppm and 0ppm respectively. The concentration of cations such as Fe, Mg, Mn and Pb of concentration range are relatively high in water samples and are found to 0.177 to 0.503 ppm, 3.520 to 4.566 ppm, 0.128 to 0.313 ppm and 0.001 to 0.031 ppm respectively. They are found to exceed the Nigerian standard for quality drinking water [1] and the World health organization [2] standards. The alkalinity concentration in water in the area ranges 120.0 to 232.0 mg CaCO3/l which exceeds the maximum …
