Abstract:
The main objectives of the study are to assess the groundwater chemistry and delineate the hydro chemical facies at study area aquifers system. Fourteen (14) water samples were collected for chemical analyses, from water wells distributed throughout the study area and analyses have been done at Water and Environmental Sanitation Project laboratory (WES) at Al Fashir town. All water samples were analyzed, according to standard methods for water examination. GIS technique was used to construct water sample location sites and Strater Demo-4 software for great cross-sections. Chemical data were manipulated using Piper diagram for chemical facies and SPSS software for statistical analyses such as basic statistics (minimum, maximum, mean and standard deviation).Generally the chemistry of the groundwater in relation to major ions (cations and anions) visualizes increase of concentrations to the northern and south-eastern side of the study area. According to Piper Diagram the dominant water type is Na+-HCO3--SO42- facies. The groundwater geochemistry controlled by dissolution of silicate minerals and carbonates as. The results show that, the groundwater in area are good for domestic uses with a few exception found to be above the recommended values given by (WHO, 2006) and (SSMO, 2009). |
