An Assessment of Groundwater Quality (TDS, EC and pH) of Selected Boreholes in Bal'ad District, Middle Shabelle, Somalia: A GIS Based Study

Ismail Mohamoud Ali

Abstract: Groundwater is almost globally important for human being consumption as well as for the support of habitat and for maintaining the quality of base flow to rivers. GIS helps in better understanding of spatial patterns and relations. The present study represents the spatial variability of ground water quality mapping for Bal?ad district, Lower Shebelle, Somalia. The thematic map of groundwater quality parameters, such as pH, TDS and EC has been tested for all the water samples in order to understand the hydro geochemistry of the groundwater. The results obtained for water quality parameter were compared with standard parameter values suggested by the WHO for drinking water suitability. The spatial contour map of these groundwater quality parameters was derived in Arc Map10.8 software using an Inverse Distance Weighted (IDW) spatial interpolation technique. The study facilitates to understand the existing groundwater quality conditions and to develop appropriate management practices to protect the groundwater sources. The results indicated variations in the groundwater quality parameters, with recommendations for further investigations and management practices.
