  abstract = {{T}he presence of fermentative hotspots in municipal waste dumps has been reported for several decades, but no study has focused on their size and shape. {T}he uncontrolled landfill of {S}oub {S}ekt, covering an area of about 8 hectares in the {T}adla plain in {M}orocco, is the source of a permanent pollution plume in the groundwater, detected by self-potential ({SP}) measurements. {T}he study aims to detect and characterize these hotspots as well as the leachates that form within them. {T}hese hotspots are typically circular and smaller than 3 m in size, and they are concentrated within recent waste deposits. {I}ntense electron transfer activities, particularly during redox reactions leading to metal solubilization, result in very low {SP} values (down to -60 m{V}), facilitating their detection. {S}everal successive field campaigns suggest that they are active for 2-3 weeks. {D}ue to the low permeability of the soils, highly mineralized leachates (average {E}lectrical {C}onductivity 45 m{S} cm-1) rich in organic ions accumulate on the soil surface at the base of the waste windrows. {T}here, they evolve by concentration due to evaporation and oxidation due to slow diffusion of atmospheric {O}2. {D}espite the small size of the hotspots generating the leachates, the accumulation of leachates in ponds and the low soil permeability limits the percolation rate, resulting in moderate but permanent groundwater pollution.},
