  abstract = {{I}n the basin of {M}ekong, over 70 million people rely on unimproved surface water for their domestic requirements. {S}urface water is often contaminated with fecal matter and yet little information exists on the underlying mechanisms of fecal contamination in tropical conditions at large watershed scales. {O}ur objectives were to (1) investigate the seasonality of fecal contamination using {E}scherichia coli as fecal indicator bacteria ({FIB}), and (2) establish links between the fecal contamination in stream water and its controlling factors (hydrology and land use). {W}e present the results of (1) a sampling campaign at the outlet of 19 catchments across {L}ao {PDR}, in both the dry and the rainy seasons of 2016, and (2) a 10-day interval monitoring conducted in 2017 and 2018 at three point locations of three rivers ({N}am {O}u, {N}am {S}uang, and {M}ekong) in northern {L}ao {PDR}. {O}ur results show the presence of fecal contamination at most of the sampled sites, with a seasonality characterized by higher and extreme {E}. coli concentrations occurring during the rainy season. {T}he highest {E}. coli concentrations, strongly correlated with total suspended sediment concentrations, were measured in catchments dominated by unstocked forest areas, especially in mountainous northern {L}ao {PDR} and in {V}ientiane province.},
