Abstract
Indiscriminate disposal of solid wastes in unauthorized places has become an increasing problem for most communities and cities in Nigeria. The two solid waste disposal sites are potentially serious sources of pollution to environment because of failure of lining system, and are situated very close to residential houses and operated haphazardly. The high pollution potential of these dumpsites is due to the fact that they usually contain almost all the types of pollutants from the source community. The contaminants can leach out through the soil, contaminating the soil itself and groundwater. In this study, six soil samples from a hole each from the two dumpsites at different depths profiles of 0, 25, 50, 100, 120 and 150cm were collected and analyzed using EDXRF and INAA with the view to elucidate: the contaminants migration due to infiltration of leachate, investigate the dynamic and rate of soil infiltration in terms of contaminants concentrations across the soil profiles, in the contaminated soil around the dumpsites at Unguwar dosa in Kaduna north area of Kaduna state. The findings revealed presence, migration and fluctuation of concentrations values in the soil profiles from top surface to the depth of 150cm. It is hoped that further research will be conducted beyond the scope of this research to underscore risk of soil contamination effect to ground water using the same techniques.
