Geophysical, geotechnical and water quality investigations of Gosa dumpsite in Abuja, Nigeria were performed to unravel the feasibility of upgrading it to a modern sanitary landfill. Nineteen vertical electrical soundings were carried out to geoelectrically characterized the site. In addition, eight soil and nine water samples were analyzed to determine their geotechnical and physiochemical properties as well as their usability. The inversion of VES-DC data indicate 3-4 geoelectric layers. Geotechnically, the soils are classified as well graded clayey-sand to silty-sand with permeability between 5.1 × 10-7 m/s and 1.1 × 10-6 m/s, which makes the groundwater prone to leachate pollution. The physicochemical parameter of the water are generally below the WHO recommended value. It could be inferred that only the northern part of the area possess the required geophysical and geotechnical characteristics for upgrade to a sanitary landfill. The high concentration of radioactive elements in the water revealed that the present dumping activities has negatively impacted the groundwater quality. [ABSTRACT FROM AUTHOR] |
