Impact of Domestic waste on Groundwater Quality in Dianeguela (Commune 6, Bamako)

In Commune 6 of the Bamako district, groundwater is exposed to domestic pollution, particularly in the Dianéguela neighborhood. The objective of this study is to analyze the groundwater in Dianéguela and identify the negative impacts of domestic liquid waste on the population. The methodology was based on documentary research, field data collection, and laboratory water quality analysis. In situ parameters (pH, conductivity) were measured. GPS was used to georeference water points. Ion chromatography was used to analyze nitrates and nitrites. An automatic sampler was used to analyze bicarbonate.The main results show that bicarbonate levels vary from 7 mg/L to 1230 mg/L, nitrate levels range from 0.001 mg/L to 416.21 mg/L, and nitrite levels range from 0.001 mg/L to 33.490 mg/L. Human consumption of this water without treatment has a negative impact on consumers' health. Excess bicarbonate at levels above 200 mg/L gives the water a bitter taste. Excess nitrate at levels above 50 mg/L or nitrite at levels above 3 mg/L can cause methemoglobinemia in infants and gastric cancer in adults. Reverse osmosis can be used to correct these non-compliances. Local and national authorities will need to raise awareness among the populations of Dianéguéla and, above all, carry out periodic monitoring of groundwater quality.
