Abstract

A hydrogeochemical study is currently being undertaken to assess the impact of the Gaborone landfill on its surrounding surface and subsurface water resources. Soil and granitic saprolite were analysed for their minerals content. Surface and subsurface water samples were analysed for water quality indicators. There are observed changes in water chemistry in the environment, which could be accounted for by the weathering of aquifer minerals being enhanced by carbonic and organic acids presumably from the landfill and sewage ponds. Moreover, two major contaminant plumes were identified as well as several smaller ones. Further research is needed to fully characterise the plumes in order to assess the landfill's full impact on the environment.
