Quantitative evaluation reports of water interventions in Mopti region, Mali
GWI Mali carried out a 3 part monitoring study of hydrostatic levels of improved water points in the Baye, Diallassagou, Ouenkoro and Sokoura municipalities in the 15 months to September 2012. Many of the boreholes and wells in the Malian Sourou sub-basin are very deep (up to 80m), making water quality studies particularly crucial. We analysed different rock types in the region, explaining how their permeability influences the static water levels. Data was collected in both the dry and the rainy season. This longitudinal study allowed us to observe whether the change in hydrostatic level was gradual or sudden, furthering our understanding of how the aquifer behaves. In some areas the hydrostatic level measurements indicate a healthy recharge of water, while others show a worryingly slow water recharge. We provide practical solutions for encouraging further data collection, and make recommendations for improved data analysis in the future in order to help improve water access and water quality in the region.
