Abstract

The improper dumping of refuse has caused not only water contamination but also air, sea, and land pollution. This can be corrected by geophysical investigation of the earth which involves taking measurement. A detailed of the environmental evaluation is carried out using electrical resistivity method with schlumberger electrode configuration. A total of 13 VES were carried out. The parameter generated was estimated from the combination of geoelectric parameter resistivity, p, and thickness h, this was contoured and presented as map. It enabled the classification of the protective capacity of the study area (Bolorunduro) into excellent (>10) very good (5-10), good (0.7-4.9), moderate (0.2-0.69), weak (0.1-0.19) and poor (<0.1) protected capacity. The data was subsequently processed and interpreted based on an assessment of the contour and geoelectric sections while, the quantitative interpretation comprises iterative computer model using a finite difference algorithm. The geoelectric sections revealed a maximum of four layers consisting the topsoil, clay/clayey sand, laterite/sand, weathered/ fractured basement and the fresh basement. The investigation reveals that the aquifers in the southern and south eastern portion of the study area are poorly protected. The interpretation shows a depth to aquifer horizon varies from 8.7m-27m.
