ABSTRACT
ABSTRACT: The groundwater in Bamako City showed 3 hydrogeochemical facies: HCO3/ Ca2/Mg2; Cl/Ca2/Mg2 and HCO3/Na
/K. Statistical methods, including a factor analysis, were applied to determine factors influencing the groundwater quality in Bamako City. Three factors, termed ‘Natural’, ‘Pollution’ and ‘Biological Contamination’ relative to the geology and the anthropogenic processes, were identified and mapped using GIS features.
