Abstract


This research investigates the effect of the Andralanitra landfill on groundwater quality in wells serving the surrounding communities. Water samples from five wells located at varying distances from the landfill were analyzed for physico-chemical and microbiological parameters across two contrasting seasons. Statistical analysis using the Pearson correlation coefficient (r) was employed to evaluate the relationship between well distance and contamination levels. The results indicate that pollution indicator bacteria (fecal coliforms, aerobic flora, streptococci) decrease with increasing distance from the landfill, while sensitive physico-chemical parameters such as turbidity and organic matter also show moderate negative correlations. Nevertheless, even the most distant wells exhibited values exceeding recommended standards, indicating a significant health risk. These findings highlight the direct impact of the landfill on groundwater quality and emphasize the need for protective measures and water treatment before consumption.
