  abstract = {{S}tudy region: {M}iddle {N}iger {R}iver, upstream to downstream of {N}iamey city, {S}ahel, {W}est {A}frica. {S}tudy focus: {U}nderstanding surface water pollution dynamics and identifying its main drivers is particularly important in regions where surface waters are largely used without proper treatment. {T}his study is focused on the {N}iger {R}iver water and assesses {E}. coli numbers, and physicochemical parameters upstream and downstream of {N}iamey. {D}ata collected over three years, supplemented by occasional campaigns, aimed to determine the spatial and temporal variability of water quality. {N}ew hydrological insights for the region: {SPM} and {E}. coli showed high values during the rainy season, peaking before the {R}ed flood. {E}. coli increased from the first rainfall events in {N}iamey with a peak occurring before {SPM} peak. {D}istinct sources play an important role on their seasonal dynamics; {E}. coli mainly originates from urban areas along the {N}iger {R}iver, while {SPM} comes from right-hand tributaries upstream of {N}iamey. {D}ownstream of {N}iamey, {E}. coli were significantly higher than upstream, highlighting the city's substantial contribution to fecal contamination through wastewater discharges, particularly on the left bank. {N}o significant differences between upstream and downstream were observed in the other physicochemical parameters analyzed. {C}onsidering spatial distribution in {E}. coli sources and environmental parameters such as rainfall and {SPM} is of major and global importance for understanding and addressing fecal contamination in urban environments.},
