Abstract
This study employed the use of multi-criteria decision approach to identify the most suitable site for a solid waste disposal facility in Ethiope East, Nigeria. Nine decision criteria which were selected based on the characteristics of the area were investigated and ranked for ten different locations. The result of the hydro-geophysical criteria showed that the protective capacity of the aquitard in the survey area ranged from poor to weak. This is an indication that the siting of a solid waste disposal facility in the study area must follow acceptable standards to guide against exposing the groundwater to avoidable pollution. The analysis of the result showed that Samagidi, Isiokoro and Eku ranked highest with a value of 72, 70 and 70 respectively. The result also revealed that Samagidi is the most centralised site among the three locations that ranked highest. Hence it is recommended that a solid waste disposal facility to serve the people of Ethiope East Local Government Area be established in Samagidi.

Summary
The selection of suitable sites for solid waste disposal is a critical issue in the planning of towns and cities. This is as a result of its serious environmental implication in terms of economy, ecology and environmental health of the people in such an area (Chang et al, 2008). It is a common fact that our towns and cities are overcrowded as a consequence of the dearth of housing infrastructures. This problem has put so much pressure on the available facilities required to effectively handle the waste generated. The challenges posed by the shortage of available facilities have called for the need for city planners to brace up to the challenge of effective management of our waste. (Chang et al, 2008)
