The briefing
A Nature study analyzes groundwater from 54 sites across contrasting aquifers in the semi-arid Sokoto Basin, using hydrochemical profiling and geostatistics to identify contamination hotspots. The work links water quality patterns to mineral weathering, rock–water interactions, evaporation stress, and localized human inputs, offering a transferable framework for monitoring and management.
