  abstract = {{I}n borehole siting within the basement rock aquifers of {W}est {A}frica, lineament analysis has traditionally been the primary hydrogeological target, where lineaments may indicate the presence of deep geological structures. {H}owever, the limited success of groundwater borehole drilling projects suggests limitations to this approach, calling for a reassessment of its effectiveness. {T}his study examines the role of alternative hydrogeological targets in relation to borehole productivity, focusing on weathering layers and lineaments. {A} comprehensive database of 2347 boreholes in {B}urkina {F}aso was developed for this purpose, revealing a strong correlation between weathered bedrock aquifer geometry and borehole productivity. {T}he analysis indicates that the thickness of regolith and saprock strongly influence drilling success rates, regardless of whether the target yield is for hand-operated or motorized pumps. {C}onversely, the presence, orientation, and length of lineaments show no significant correlation with borehole productivity. {T}he study emphasizes the need to shift focus from lineaments to weathering properties in basement aquifer exploration and highlights the dominance of a landform-regolith conceptual model over a deep geological structure model. {T}hese findings have implications for achieving universal access to drinking water and food security in {W}est {A}frica's bedrock regions.  {P}our implanter les forages dans},
