Ensuring access to clean drinking water remains a significant challenge in many developing countries, particularly in rural areas. The existing water purification methods are often inaccessible due to high costs or a lack of technical expertise. To address this issue, we have tested a simple and cost-effective method for purifying Ayin Kiam surface water, specifically for use by rural communities. This method involves utilizing an extract from Moringa oleifera leaves as a natural coagulant, flocculent, and antibacterial agent to clarify turbid water and eliminate pathogens, resulting in clean drinking water. Our research findings provide unequivocal evidence that the aqueous extract of Moringa oleifera leaves significantly improves various water quality parameters. These include pH levels (8.63-8.51), total dissolved solids (6360-4430 mg/L), conductivity (9.67-7.02 mS/cm), turbidity (123-62.4 NTU), iron ion concentration (0.08-0.0 mg/L), and coliform counts (398-177 CFU/mL). The enhancement in water quality can be attributed to the presence of diverse chemical compounds in Moringa oleifera leaves, such as carbohydrates, proteins, and carboxylic acids. The existence of these compounds has been confirmed through gas chromatography-mass spectrometry (GC-MS) analysis. Previous studies have shown that these compounds have the capability to adsorb substances onto their surfaces, thereby supporting the effectiveness of aqueous extracts of Moringa oleifera leaves as an alternative for water purification. Given the severe health implications associated with chemical coagulants, the utilization of Moringa oleifera leaves as natural coagulants in water purification presents a cost-effective solution. These leaves are readily available throughout the year and are not dependent on complex climatic conditions. Thus, the use of Moringa oleifera leaves holds great promise for providing clean drinking water to rural communities in a sustainable and accessible manner.
