Abstract
Shortage of land for waste disposal and inappropriate landfill site is one of the biggest
problems in most of large urban areas. Therefore more efforts are needed to overcome this
problem. Most of the landfill sites are selected randomly, and waste is burned and not
treated, which impacts nature and human. The main aim of this research is to determine a
suitable Petroleum Landfill Site (PLS) with less impact on environment. In this research, a
potential site for an appropriate area for the Shama Ahanta Area was determined by using
Geographic Information System (GIS) as a tool to aid the decision making process. To
achieve this purpose, thematic layers and different tabular data such as topography, land
use, roads network, ground and surface water, infrastructure, and urban areas were
collected from different institutions and governmental agencies. Thematic maps were used
to create the suitability map for the area and the result was compiled to the buffer zones
around sensitive areas. By using multi-criteria analysis, a candidate site was allocated
taking into consideration the sensitive areas in order to find out the best location for the
anticipated PLS
