【 摘 要 】

The disposal of wastewater is a problem of great concern throughout the worldspecifically in developing countries. This study investigates the impact of indiscriminatewastewater disposal on soil in Akindeko and Abiola halls of residence at the FederalUniversity of Technology, Akure Nigeria. Soil samples were taken from the wastewaterdisposal site at the surface and varying depths of 10 cm and 20 cm while the control sampleswere taken 10 m away from the polluted soil surface. Physico-chemical and bacteriologicalproperties determined include; colour, odour, soil weight, particle weight, bulk density,porosity, pH, Copper, Manganese, Zinc, Lead, Cadmium, Cobalt, Iron, Sodium, Potassium,Calcium, Magnesium, bacteria, fungi and coliforms. The results showed that all the physicochemicaland bacteriological properties of the soils have relatively high concentrationindicating pollution compared to the control samples. The pH ranged from 8.7 to 7.2 while Caand K have a range of 1277 ppm to 773 ppm and 1273 ppm to 754 ppm respectively. Thehighest concentration of Zn and Mn are 19.30 ppm and 11.70 ppm respectively. It isrecommended that a sustainable wastewater treatment plant should be provided to treat allwastewater generated from all hall of residence in the university and at the same time the soilsin the area require various remediation technologies like bioremediation andphytoremediation by growing certain plants in the area to minimize the rate of contaminationand extent of future pollution problems. This will go a long way in preventing environmentalpollution in the study area.
