Sustainable Groundwater Purification: Leveraging Local Materials for Lead, Iron, and Cyanide Removal in Ghanaian Mining Communities

This study aims to evaluate the effectiveness of Moringa Oleifera seeds and banana peels as natural coagulants for the removal of lead, iron, and cyanide from groundwater in mining-affected communities in Ghana. Experimental laboratory analysis was used to analyze groundwater samples collected from five mining communities in the Atwima-Kwanwoma and Obuasi East districts of the Ashanti Region, Ghana, and treated with Moringa oleifera seeds and banana peels as natural coagulants. The concentrations of E. coli, cyanide, lead, and iron were measured before and after treatment. The study found a 100% removal efficiency for E. coli, cyanide, lead, and iron after treatment with Moringa oleifera seeds and banana peels. These results align with previous studies indicating the efficacy of these natural coagulants in water purification as the Moringa oleifera seeds and banana peels are effective, low-cost natural coagulants for removing contaminants from groundwater in mining communities.
