Abstract: This study applied physico-chemical and spatial techniques to investigate potential transport of leachate from the Dompoase Landfill site in Ghana. Groundwater contamination gradient from the Landfill site provided evidence of leachate transport and potential impact on adjoining communities. Static water level (SWL), pH and electrical conductivity (EC) of well water, as well as nitrate (NO3-), phosphate (PO43-) and lead (Pb) concentrations showed negative correlation with distance from the Landfill. The negative gradient of SWL suggests relatively deeper water table in areas proximate to the Landfill. For the other parameters, the negative gradient provided evidence that the contamination potentially emanated from the Landfill, but appeared to attenuate naturally with distance. Nickel (Ni) and mercury (Hg) however behaved differently spatially. While the concentration of Ni in groundwater did not change with distance from the Landfill, Hg showed a positive gradient. Presumably, there were other sources of contaminations from Hg other than the Landfill. A sharp contrast existed in groundwater quality between communities located at the east and west ends of the Landfill. The groundwater quality was suitable for drinking at the eastern end, but relatively poor at the western end. Potentially, the groundwater flow and contaminant transport was influenced by a shallow aquifer, which maintained a contamination gradient that affected communities located west of the Landfill.
